I am looking for a textbook for front desk orthodontic staff who have no
orthodontic experience. Ideally, the book would cover dental
nomenclature and orthodontic numbering, an overview of orthodontic
appliances, and a discussion of orthodontic records. Is anyone aware of
such a text?

I have an adult male patient who has been in treatment for 9 months. Total
treatment is scheduled for 12 months. He has fallen behind on his payments,
and has paid for only 1/2 of his treatment. He was in today and told us that
his insurance is not paying as much as he thought they would.
He informed us that he would NOT honor his contract and that he would pay us
an amount that was considerably amount less than agreed upon.

What rights do I have as far as terminating treatment.?
Can I refuse to schedule an further appointment until his account is paid?
Can I terminate treatment, take his braces off and give him retainers?
Can I not give him retainers unless his account is paid?

What is the best way (and legal way) to approach this without "abandoning the
patient" or leaving him with an unstable occlusion?

Thanks for all your replies to this difficult situation.

However a small error occurred (I should have taken typing in high school!) The sentence beginning "Her maxillary central were previously avulsed completely..." should read "maxillary centrals", meaning both were avulsed and reimplanted, and are now failing.

I can't remebr if the patinet required extractions in the lower arch - if this is the case a neat plan is to use the lower premolars into the central sockets - you need a good delicate surgeon (get him to read Andresen's book on trauma of incisors) the success rate is as good as implants.

but you need close coporeation with someone to do the RCT on the transplanted teeth then to reshape the crowns

you place the molars side on

we have used this with good results in a number of case following trauma and in hypodontia

In Newcstle on our hypodontia clinic this is a common problem
if there is no lower crowding or need for retraction of the incisors we
mainatin the E's as long as possible to keep bone - if necessary building
crown height to keep the occlusion
as and when they are lost 0 acid etch bridges work very well

if there is crowding then close the space.
ps.
class III molars are perfectly stable

There probably are such texts but my suggestion is to close your office for
a long lunch hour (3 hours or so), order in sandwiches or pizza, and teach
your staff directly, creating the manual as you go. TGS.

Laws differ. In Ontario you cannot abandon a patient for non-payment, but there
is a protocol for stopping treatment. My advice is to contact either a lawyer or
your state/provincial licensing association (or both). TGS.

Hello group

I have an adult, mandibular deficient patient, who is part
way through a combined surgical-orthodontic
treatment in Toronto, Canada. She has not had her surgery
yet.

She will be moving to Ireland (Belfast area) for about one
year.

Can anyone recommend an orthodontist/surgeon who could take
over her treatment???

Thank You

John,

You have no obligation to work for free. What would your attorney do if you
stopped paying what you agreed to pay?

Simply inform the patient that treatment has been terminated because of
unmet financial obligations. Also inform him that emergency services ONLY
will be provided for 30 days. Inform him that he needs to seek orthodontic
care because of the risks of having braces without treatment. Then send the
letter certified. That's all you need to do.

Regarding the non paying patient, our contract with our patients specifies
that I can terminate treatment for nonpayment. I send the patient a
registered letter that he is in violation of our contract and can pick up
his records, direct where he wants them sent, get assistance in finding
another doctor, or have his braces removed. The legal definition of
abandonment is not the same as patient "dismissal" . Check with your state
dental board for the exact procedure required to dismiss a patient.

Re: textbook for new front desk. If you can find something I'd like to know
about it also. My chairsides have brought in their dental assistant texts
but there is not much on ortho. This is a real problem for our profession.
Al Landucci, pres of Calif Assoc Ortho, is trying to get something started to
address the staffing education problem.
Re:invisalign use - call me at 650-368-8348 or email at orthodas @aol.com and
I'd be glad to answer any questions and tell you my experiences. You could
also talk to patients if you'd like.
Re: retained SUBMERGED lower E's. The key here is the word submerged. How
submerged. As a former restorative dentist for 16 years before going into
ortho, I can tell you that the important point here is alveolar bone height
and width. Now that there are the grafting procedures you have many more
options. I would consult with a perio or oral surgeon who has experience
grafting and determine when would be the best time to ext and graft. Because
the long term consequences of leaving these teeth is not good. You can have
them restored but they will continually be a problem. It may be that
adjusting the width now to conform to bi size and then later ext and grafting
is indicated or it may be that now is the time to remove them.

John:

Not knowing what type of case this delinquent patient was may change things but lets assume that since it was a 12 month case it was not a biggie nor was it a significant extraction case. My answers to your questions are several, no, no, and no. My first question though is why would you be worried about abandoning this patient? Look at it this way, he agreed to a treat plan, he agreed to pay a certain fee in a certain manner, and he unilaterally decided not to honor his financial obligations for his elective therapy (orthodontics is elective) and he unilaterally determines that you should treat for less. He abandoned you!

Lets look at your questions. Your rights are that you can (a) acquiesce to his demands and accept less or (b) tell him to take a hike and finish his treatment elsewhere. If you are going to terminate tell him in writing why (non-payment) give him sufficient time to seek substituted care (4-8 wks.), inform him that he still needs continued care and that you will be available for emergcies only during this 4-8 weeks, that you'll make his records available to him or any subsequent treating practitioner, etc.

You cannot refuse to give him any more appointments until his account is paid. This is consructive abandonment.

You cannot terminate in the middle of treatment and place retainers unless he agrees to accept an unfinished result as the removal of appliances and th placing of retiners may interfer with his ability to seek substituted care.

You cannot refuse to give him retainers until his account is paid. You can only withhold clinical tratment for clinical reasons, not financial ones.

In short, you have a right to tell this bozo to pay up or take off. Rights are funny things. Your decision to exercise them may cost you but they are your rights to exercise. ost Docs and Lawyerrs out the would tellyou to eat it (finish the case and move on). This is smart risk management as you just paid a high price for the cost of aspirin (to get rid of the headache)      It doesn't address the etiology of your headache (poor account management)

Hope this helps.

I have an adult male patient who has been in treatment for 9 months.  Total 
treatment is scheduled for 12 months.  He has fallen behind on his payments, 
and has paid for only 1/2 of his treatment.  He was in today and told us that 
his insurance is not paying as much as he thought they would.
He informed us that he would NOT honor his contract and that he would pay us 
an amount that was considerably amount less than agreed upon.

What rights do I have as far as terminating treatment.?
Can I refuse to schedule an further appointment until his account is paid?
Can I terminate treatment, take his braces off and give him retainers?
Can I not give him retainers unless his account is paid?

What is the best way (and legal way) to approach this without "abandoning the 
patient" or leaving him with an unstable occlusion?

Thanks for all your replies to this difficult situation.

I can't remebr if the patinet required extractions in the lower arch - if this is the case a neat plan is to use the lower premolars into the central sockets - you need a good delicate surgeon (get him to read Andresen's book on trauma of incisors) the success rate is as good as implants.but you need close coporeation with someone to do the RCT on the transplanted teeth then to reshape the crowns you place the molars side on we have used this with good results in a number of case following trauma and in hypodontiaross Hobson[Ross Hobson]

In Newcstle on our hypodontia clinic this is a common problem
if there is no lower crowding or need for retraction of the incisors we
mainatin the E's as long as possible to keep bone - if necessary building

as and when they are lost 0 acid etch bridges work very well

if there is crowding then close the space.

Drew Kohl asked about the Invialign course and other questions. Here is the
company's latest news release, which reinforces my hunch that this will
become the method of choice for GPs/"orthodentists" and dovetails exactly
with the wave of "cosmetic" dentistry. Notice that it begins with references
to orthodontists and subtly the references change to dentists. We may be the
scientific communities first distributed beta testers testing for our future

Straightening Teeth Over the Internet; Thousands of Orthodontists Use Web for
First Time to Treat Patients

Major New Internet Initiative in Orthodontics

SUNNYVALE, Calif., April 6 /PRNewswire/ -- Align Technology Inc today re-
launched invisalign.com, a website that helps orthodontists straighten teeth.
The site -- which targets both doctors and patients -- is an integral part of
the Invisalign System (TM), a new, virtually invisible way to straighten
teeth.

Align Technology launched the Invisalign System (TM) in June 1999. Since
then, the Company has certified over 30% (more than 2,600) of U.S.
orthodontists to use the System. Over 2,500 patients are now straightening
their teeth the 'wireless' way.

Doctors treating patients with Invisalign spend approximately one hour per
case on invisalign.com viewing a 3D graphical representation of their
patient's teeth via ClinCheck(TM), a movie-like software program showing
teeth moving from present position into a final, straightened state. The
doctor diagnoses and plans the case by scripting and editing the movie of the
patient' s prescribed treatment -- all via the web. This makes invisalign.com
the only "must view" web-site in orthodontics and one of the stickiest
websites in the medical world.

There are already over 1000 registered users of invisalign.com. This figure
is expected to grow rapidly as the website becomes a central means of
communication between the doctor and Align Technology and, eventually,
between the doctor and his patients.

invisalign.com is a powerful platform for bringing together the 8500
orthodontists in the US. As a group these doctors consume $1 to $2 billion
in supplies per annum and have an aggregate income of over $2 billion, or
$250k per doctor. In addition to providing a quality community site for the
industry, Align intends to sell to orthodontists via invisalign.com
everything they need to run their practices.

Orthodontists are not the only visitors to invisalign.com. The website is
also valuable to potential patients looking for information on Invisalign;
Invisalign-certified orthodontists in their neighborhood; testimonials of pati
ents who have gone through treatment; and a customer service forum where they
can interact with customer support representatives and current patients.

Expanding to Serve All In the Dental Arena

Orthodontists and their patients are just the beginning. Align intends to
make invisalign.com the portal of choice for tens of thousands of dentists.
For example, the site will offer dentists and patients new versions of
ClinCheck(TM) to help them visualize treatment solutions for cosmetic dental
services.

invisalign.com is another step in Align's quest to bring 21st Century
technology (not limited to the Internet) to the practice of orthodontics.
Align has devised a multi-step system for straightening teeth without the use
of metal braces:

1. The doctor sends digital photographs, x-rays and an impression of the

patient's teeth to Align via e-mail and by courier. Using this data

Align makes the 3D movie showing the tooth movements necessary for a

straight smile.

2. Then, the doctor uses invisalign.com to tell Align how to treat the

patient's teeth. This description becomes the script for the

ClinCheck(TM) 3D movie predicting the entire course of treatment.

3. Days later, both doctor and patient can view the movie using Align's

unique web-based diagnostic tool (ClinCheck)(TM). This revolutionary

software allows them to take a virtual tour inside the patient's

mouth. The patient sees her teeth as they are now, the way they will

be at the end of treatment and all the stages in-between.

4. The doctor's role is to edit the movie and approve the "final cut."

The editor's remarks are entered into the website. Align then uses

CAD/CAM technology to translate the approved "final cut" to create a

series of customized "aligners" for his patient.

The aligners are clear, lightweight polycarbonate devices that fit over the
patient's teeth and are worn at least 20 hours per day. Unlike metal braces
the aligners may be removed for eating, brushing, flossing or even kissing.

Most importantly, the aligners are clear, plastic and disposable, like
contact lenses that straighten teeth. They are nearly impossible to see when
worn, which removes a major barrier for the millions of adults who wish their
teeth were straighter but would never consider wearing metal braces. Just as
contact lenses eliminated the need for unsightly spectacles, Invisalign
eliminates the need for a mouth full of metal.

According to Align, 50% of adults age 25-to-49 -- or 50 million adults --
"wish their teeth were straighter." Yet less than 1% opt for braces every
year. This represents an enormous opportunity for orthodontists to expand
their patient base and significantly increase their revenues.

I have seen a patient for consultation. He presents as a 16yr old with a
history of naso pharangeal carcinoma of the naso-palatine area diagnosed
and treated at age seven. He received large doses of radiation which has
destroyed all of the hair follicles on his head. Dentally, he has
arrested growth of all teeth at the time of the radiation. There is
little root formation on the second molars and incomplete root formation
on the bicuspids and cuspids. The maxillary centrals are flared and the
maxillary right cuspid is erupted labially and slightly blocked out. He
has a constricted maxilla with bilateral lateral open bites. The boy
would like his "front teeth to look better".
Does anyone know the problems with moving teeth through heavily
irradiated bone? At most I would consider aligning the anteriors.
Thanks for the input.

Hi Mary,
Just a thought about training front desk personel without any ortho
experience. Do you have a R.O.P. program in your area? They are usually
administered through a school district and have a dental assistant program
(and usually a dental front desk part also).
If you don't, I may be able to get the manuals from our R.O.P. and send them
to you. I don't know what the cost would be. Let me know.

The California Orthodontic Association published a letter that can be sent to
patients informing them of your intention to dismiss them from your practice.
Usually patients that are behind in their financials are also poor about
keeping appointments and hard on their appliances. Your decision to
discontinue can be "lack of cooperation".   If you would like a copy of this
letter, pleae let me know. I have been using it for years, more as a
collection letter, but my intent is clear to the patient and parents. Very
seldom do I actually have to dismiss someone, but it acts as a good "wake-up
call".

        Why the criteria of obtaining the "O" center in this analysis differs from
some books to the original articles by Dr. Viken Sassouni? Are there any
explanations for the changes that are made? What principles for marking this
point are the orthodontists from USA using nowadays? And why?

The worm will probably turn at least once more. When they have
recruited the dentists to do the ortho and the company needs more
profit they may then recruit dental technicians and then DIY at home
kits. I can see a DIY kit really endearing itself to the dentists,
just like they may plan to do to orthodontists first.

Thankfully, like many technology advances on the web, others have
access to similar materials (for suckdowns) and others will see an
opportunity to make a profit and this will introduce its own
competition.

Invisalign looks interesting from my view in Australia but again from
this distance it looks like by using them you just may be helping to
develop yourself out of some work.

Regarding the adult patient who decided to not honor his contract..

You have every right to terminate treatment of this case based on the decision of the financially responsible party to abrogate his contract without cause.

There is a fundamental question to ask first. Is the patient is in equal or better clinical condition today than he was when you started treatment?

If the answer is "yes" and the patient is clinically (excessive emergencies, abysmal home care), or administratively (excessive missed appointments), or socially (a real jerk, loud, verbally abusive/demanding), or financially (non-payment) uncooperative, you may terminate treatment.

There are a couple of caveats. You must have:

Evidence that you have expended adequate effort to resolve the problem, and have failed to do so.

Evidence that you have given the patient/responsible party adequate written notice of your intentions.

My recommendation to a client would be to, after adequate notice, remove this patient from the practice. You have a right to quality of life within your practice and, subject to the answer to that fundamental question I mentioned, you have no legal, moral, or ethical obligation to continue to treat a patient who actively damages the quality of life within your practice.

An attorney may well give you the opposite advice. Remember that an attorney can get in no trouble and has no risk at all in telling you to "play it safe" and finish the case. After all, it is not his money being lost nor is it his quality of life that is suffering. If, in fact, you do hear opposite advice from your attorney, ask him to quote the specific statute or case law upon which his advice is based. You will likely find that the advice is based on personal opinion and not statute or case law. To my knowledge there has never been a single case where a doctor was ruled against when the doctor/practice terminated a patient after fulfilling those two caveats.

Dear Group,

In continuation of discussion of dealing with subdivision cases, asymmetries
are hard to dealwith. Especially in good many cases if the mandible is weak
on one side -it also results in maxilla being smaller on the same side
because of the reduces functional forces of the affected side. In such
situation how does one resort to any funcational appliance -as it will
impede maxillary growth as well.

We have a 10 year old female patient. Due to ankylosis she underwent
condylectomy on the left side 3 months ago. Occlusion (Overjet, overbite and
midline) is perfect at this time but during mouth opening the mandible is
deviating significantly to the leftside. She is likely to develop asymmetry?
I invite opinions on what are the options available to treat this girl - to
give the best possible outcome. What happens if she is left untreated.

I would highly recommend "The Book" by Dean Bellavia.
This covers very comprehensively all office procedures and includes a
section on dental anatomy etc.
Not a cheap book but one I have found very useful over the past 10 years.

It is available direct from his company :Bio-engineering Co., Buffalo, New
York.
This is the best address I have got unfortunately.

If anyone has a better contact address perhaps they might post it here.

Dear Mary and Similarly Interested Colleagues-

Don't reinvent the wheel. An excellent orthodontic text and workbook were
developed by Dean Bellavia who runs (ran?) the Bio-Engineering Co. out of
Buffalo, NY, an orthodontic consulting co. I could not find him listed in the
ATT directories. Perhaps one of you can supply his phone/adddress.

Some years ago Dean came out with "THE BOOK" and some of you may have it. It
was a detailed treatise on the nuts and bolts of running an orthodontic
practice. I would recommend it for those of you who don't want to afford a
consultant at this time, but have aspirations to be super organized. Bellavia
and "attention to detail" are synonymous. No financial interest---just
admiration.

Hope this is helpful.

His website and a recent nationwide mailing contain images illustrating orthognathic surgery treatment simulations on a series of patients having a variety of skeletal malocclusions. The more popular simulation software programs have been used in "auto treat" mode, meaning that no touch-up was done on any of the images. An actual postoperative outcome is also shown for comparison. I prepared these simulations with the help of Dr. Myron Tucker and Dr. Arlet Dunsworth over two years ago. They were part of a pilot study in preparation for a thesis project currently underway at the University of North Carolina. I showed the results to each of the vendors at the AAO meeting in San Diego and offered to send copies to those interested. Dr. Blaseio asked that I send him a CD with the images so that he could use them in a lecture he was giving last summer. I was flabbergasted to find that he had posted this material on his website without the permission of the authors or releases from the patients whose faces are being splashed all over the internet. I was even more shocked to learn that he has included this material in a nationwide mailing of a brochure promoting his products. Again, no permission, no releases. This was clearly not my intent in giving him access to these images. I would like to set the record straight. I realize there may be a limited readership of this list, but word can travel and it appears there is an international audience. [1] These images were prepared with software versions which are several years old, yet Dr. Blaseio implies they are current. This does a disservice to the other vendors to have made multiple improvements in image simulation since this pilot study was done. [2] Dr. Blaseo states that I clearly demonstrated the superiority of Quick Ceph Image Pro at a CE course held at UNC in April 1999. http://www.quickceph.com/qc2000_index.html I made no such statement. I simply displayed the images, explained how they were generated and allowed the audience to draw their own conclusions. I *did* say that Quick Ceph and DF Plus seem to manage patients having vertical changes (open bite and deep bite corrections) better than the other products. All products seem to perform reasonably well on sagittal movements. [3] I in no way endorse Quick Ceph Software. In fact I don't use it on a daily basis. I have tried to forge a good working relationship with all vendors in completing this pilot study and starting the larger research project, and it is an injustice to them that this material has been used in a misleading manner for self-promotion and advertising. It is clear that Dr. Blaseio likes to play by the rules....as long as he is the one who makes them. Paul M.

Perhaps it got lost in cyber space, or I possibly missed it. Let's try it again! Greetings All- Though I haven't been much of a contributor as of late, I certainly have enjoyed the postings. Being retired, with the exception of some limited teaching, should afford me a lot of free time. However, being somewhat inefficient, and without the assistance of my organized staff to keep me on track, I find myself still playing catch-up! A few preliminary remarks: It it is all well and good to "leave orthodontics to the orthodontist and prosthetics etc.", but there are also socioeconomic issues to be considered, perhaps(?) more in other countries than ours. There are some patients whom you know will never be candidates for the ideal prosthetic restoration, and for whom protraction of posterior teeth in the face of congenitally missing premolars would be providing the best service, taking into consideration the skeletal pattern, the size of the teeth etc. We should all be very concerned about over-retracting the lower anterior teeth when protracting lower molars. Obviously, the key to success is to enhance your anterior anchorage, reduce your posterior resistance, and very important, to reduce your force levels. Bonding a lingual wire to every tooth from first premolar to first premolar goes a long way to fulfilling the first objective and I strongly recommend it for "long distance" protraction. Those of you who have the advantage of Tip-Edge mechanics can fill the brackets with a rectangular wire and add the potent resistance of root uprighting springs. I have found that by placing the wire in the relatively larger .036 molar double tube, there is a reduction in the amount of force necessary to protract the molar. Although some tipping may occur,once the space is closed, this is resolved by switching to the edgewise tube and subsequently leveling. (Obviously none of us would attempt to protract the first and second molar concomitantly, right?) I am aware that edgewise brackets now have the capability of receiving uprighting springs, (thanks, Dr. Begg) but I feel the problem of increased posterior resistance is created with a full slotted wire in the edgewise tube necessitating increased forces for protraction which can result in undesirable anterior over-retraction. Tony Gianelli certainly has the right idea with his Bidimensional Technique and I recommend a review of his articles for you edgewise mavens. Additionally, anterior anchorage can also be enhanced by placing an off-center bend, a la Mulligan, just distal to the first bicuspid in those instances where the second bicuspid is congenitally absent or has been extracted. A related issue I would like to mention is the integrity of the contact point between the 1st bicuspid and the molar in second bicuspid (minimal anchorage) extraction cases, particularly in adults, and also in those instances where the molar has been protracted a long distance when the 2nd bicuspid is congenitally absent. Frequently, the contact is loose, or reopens just enough to distress our periodontal colleagues. My clinical impression is that bonding a buccal wire between the molar and first bicuspid for 6 months or more after the space has been tightly closed allows the tissues to reorganize and mature and can minimize this problem. But even then there is no guarantee for a permanently tight contact. One last issue is the minimal occlusal contact area of the maxillary second molars when only lower second bicuspids are missing or extracted and the spaces closed. Your speculation relative to this occlusion is as good as mine. Perhaps some of may have some long term data. Sorry to be so long winded, but as you can see there are many considerations regarding this problem. We would all welcome additional insight into this problem.

Remember, this technique is only a tool for our trade. Our trade is healthy occlusion and esthetics, not braces. Our expertise is in diagnosis and treatment planning far more than in placing appliances. As such, I believe that Invisalign, and whatever variations that follow, will not only open new markets for us directly, but will significantly broaden the demand for our more "traditional" services. Also, since the advent of Bionators, straightwire appliances and nickel titanium wire have not made orthodontics so easy that any GP can do it, neither will Invisalign spell our demise even if GP or home kits are offered.. While there may be lots that this appliance can do, there will be much it can't do. Dx and TxPlanning will be just as tricky, with as many shades of gray, as there are with any appliance. For instance, this appliance, so far anyway, is strictly INTRAARCH mechanics. I will not be surprised if we see anchorage effects create beautiful but mismatched arches since real anchorage vectors are not predicted in the Clincheck diagnostic process. Just like with fixed appliances, I think you should feel comfortable educating and encouraging your GP's to get involved (when the time comes), for after the first few cases that don't turn out, you'll still have a great source of referral. So far, I have four cases in progress with the fourth being my own self (just three days into a 20 step treatment), and two more in the lab. So far, I have felt totally in control of the treatment planning process and the appliances have been impeccably fabricated. I have also had to reject some cases from consideration - a choice only an orthodontist could make. So, if any of you are feeling too defensive to get involved, I suggest you let your guard down. There is great potential here for something that you would be foolish not to have in your bag of tricks. BTW. Absolutely no financial interest.

Dr. Tucker informed me that Gunther Blaseio did, in fact, ask him for permission to use the Quick Ceph simulations and that his patients had given permission for publication of their likenesses.

The text represents a letter to the patient, but can be adapted for the responsible party. In view of the continuing lack of cooperation on your part, I am hereby advising you that I shall terminate your treatment thirty days from the date of this letter. In my opinion, you can benefit from continued orthodontic care and I urge you to seek the services of another orthodontist. If you decide not to have another orthodontist take over your treatment within the next four weeks, I recommend that you contact my office to have the appliances removed since there may be health problems from wearing appliances without periodic maintenance and adjustment. these potential problems include decalcification of teeth, increased risk of cavities and the possibility of injury to soft tissues of the mouth from loose or broken appliances. This should be sent by certified mail with a return-receipt-requested. Save the receipt in the patient's file, or if the letter is returned unopened or not deliverable, save the letter in the file. My experience has been that most patients or parents respond to this letter in a positive way. That is, they are more likely to clear up their account and proceed with treatment than go elsewhere. If the patient returns after a lengthy period (6 months) and wants to continue treatment, then they are informed of the necessity of new treatment records with a new diagnosis, treatment plan and fee. I have found this to be a reasonable way to prevent possible problems in the future. I hope this helps to your patient management a little easier. See you all in Chicago.

Likewise, it is very costly, and demands full cooperation from the patient. Furthermore, just as any removeable appliance, it only produces a tipping movement of the teeth, rather than a bodily movement. So if you want to save alot of money for yourself as the orthodontist, and save the patient alot of cash, a modified Essix retainer can easily produce equal results with minimal labwork. I can prove that. So anyone who thinks that this new company isn't a total marketing gimmick and isn't going to go after orthodontists' pockets is totally mistaken. By the way, no financial interest in Raintree-Essix here.

Greetings,
    I intend to send an anonymous survey to my patients with the hope of getting some feedback on how our team is doing (?Do I really want to do this!). I have an idea of some of the questions that I would like to ask, but I wonder if anyone else has ever done this before. Anyone care to share their thoughts?

Hi All,
I thought you would all benefit from this disertation sent to me by my IT
person.
Good Luck! It was nice to see many of you in Chicago. This meeting had more
technological content than any AAO meeting before it.

You may have heard about this morning's world-wide virus attack called
"ILOVEYOU", and this is a perfect example of what NOT to do. Opening
attachments without first scanning them for viruses is just asking for
trouble. .exe, .com, .vbs, .js, .ws, .wsf, .bat, and .cmd files (there are
more, but these are the main ones) are executable, that is they are not data
files, they are actually code that executes. If you get any files with these
extensions, NEVER open them from your email program. In fact, don't open
them AT ALL unless you're absolutely sure that they do NOT contain malicious
code. Data files such as .jpg, .mp3, .tif, etc. cannot execute code so they
cannot contain viruses, but Microsoft Word and Excel and other Office
products can contain macros which do execute code. These programs also have
security settings to prevent unauthorized code from executing, but a virus
contained in a program (.exe., .vbs, etc.), or even a macro that someone
chooses to run, could disable this security, so you need to keep an eye on
the security settings to make sure you're protected. A program can do
anything a user can do, such as modify security settings of other programs
and delete files.

The Melissa and ILOVEYOU viruses work by reading the victim's address book
and sending itself to everyone in there AS THE USER WHO OPENED IT.
Therefore, it looks like it came from the user who opened the attachment.
The problem with .vbs files is that there's really no way of programatically
determining whether or not it's doing something harmful. Virus scanners have
a list of viruses and they scan for the "signature" of these viruses in
files on your system and sometimes even in email attachments, but these
signatures need to be downloaded every so often in order to have the latest
list. If a new virus hits you before its signature has been downloaded to
your antivirus software, you won't have any protection aside from knowing
not to open it. At the time of this writing, Norton's LiveUpdate still does
not contain the signature for ILOVEYOU. Some virus scanners can detect code
from unknown viruses based on known destructive patterns, but this
technology is still in its infancy and doesn't catch everything. If it did,
antivirus companies would be out of business.

Windows Scripting Host programs (.vbs, .js, .ws, .wsf) are very powerful
utilities but the potential for harm is also a huge concern. They are much
like .bat files, which contain DOS commands, but they're written in Visual
Basic or other scripting languages and can do anything a user can do and
more. A program that contains some code such as "myfile.delete()" is not a
bad thing, I use that command myself in scripts I create to clean up
temporary files when my script is finished. But if I said "for each file in
c:\; file.delete(); next", it would delete the entire contents of the hard
drive, which IS a bad thing. Unfortunately the actual code to do that is not
written in stone, there are many ways to do the same thing, therefore it's
practically impossible to write antivirus software that will catch these
programs before they've been discovered. So the only way to find out if a
script is harmful or not is to either have someone familiar with the
scripting language eyeball it and make a decision, or wait until some poor
victim finds out the hard way. The only foolproof method for eliminating
viruses is to never, ever, double-click on an attachment unless you're
absolutely sure that it's safe. Some files are easy, a .jpg file will never
be able to execute code on your system, but others require education. If
you're not sure, ask someone who knows or just delete it. If you must send
an executable file to someone, call them on the phone first and tell them
that the file you're about to send them is OK to execute.

Here is a checklist to keep your system as safe as possible:

1) Keep your antivirus software up to date. Most have automatic updates you
can configure. Antivirus software can't catch everything but they do help
immensely. Norton and McAfee (and some others) have server versions for NT,
Exchange, Proxy, etc. that can scan files before they even reach the user.
2) Lock down the file permissions on servers and even workstations so users
only have the access they need to get the job done. If my wife accidentally
opened the ILOVEYOU virus (she knows better), it would replicate itself to
everyone in her address book but the MP3s and JPGs on the server would be
safe because she has read-only permissions to them. Viruses can only run
with the permissions of the user who opened them.
3) Administrators, keep a separate admin account and do your day-to-day work
as a regular user. The NT Resource Kit has su.exe, which allows you to run a
program with elevated privileges by supplying the admin name and password,
so you don't have to log out to reset someone's password.
4) Don't open questionable attachments, even if it comes from someone you
know. Unfortunately, not everyone learned from the Melissa virus which was
relatively harmless. ILOVEYOU is very destructive and operates the same way.
5) Closely monitor your applications' security settings, especially Word,
Excel, Internet Explorer, Outlook, and Outlook Express. Microsoft supplies
System Policy files for the entire Office suite and IE that will enforce
settings upon login. Use them.

If you have any concerns about your company's security (or lack thereof),
Langtech will be able to provide a comprehensive review of the hardware,
software, and policies in your company and install any necessary software,
hardware, and system policies to make sure your computers are doing all they
can to keep themselves virus-free. The final step (and biggest security
hole) is user education, everyone should know not to open attachments unless
they're absolutely sure they're safe. They haven't written a virus (yet)
that can spread itself without the help of users.

What are the chances of eliminating our plaster models and substituting them with 3-D models from Ortho Cad? The cost is $35 and the effect on the parent is high techish. Will the ABO accept? The images are watermark to show no tampering.It appears that high tech is rapidly changing orthodontics. Does anyone have any opinions on how Acuscape is going to effect ou diagnosis in orthodontics? It is certainly an exciting technology.

Hi Tim:

Up until a year ago, we used to send out a survey to all active patients
in treatment at their six month mark.   We would simply run a report on
all patients that became ACT for a certain month six months earlier.

We asked questions pertaining to service provided, ease in financing,
attention to details, ease in making appointments, perception as if our
office ran on time, comfort and of course if they thought things were
going more smoothly than they had intended. These questions had
multiple choice answers along with blanks for comments. I also asked
that they make comments about the staff - positive and negative.

They could sign their name or not. We had close to an 80% response
rate. We would send out one color for adult patients and one for
parents of patients. After doing this for three years and fine tuning
the office based on constructive criticisms, we stopped sending out the
forms. Stopping had more to do with not knowing how to run the same
report with our new system than not being interested in parent/patient
comments anymore.

I would highly recommend it. I would also tell you not to bother doing
it if you are only looking for the praises. You had better have some
thick skin and be open minded. Some comments are ridiculous but at
least you get a better idea of what is expected of you and what the
patient/parent perception might be.

Good luck, Mark

Hey Roy,
I'm here in Lyon, France following the AAO meeting (and my wife). We have
been using OrthoCad for about 6 months, but impressions are still necessary.
Redmond Orthodontics has agreed to beta test Orametrics which does intraoral
scanning, produces a 3D model which can be segregated into individual teeth
and then diagnostic setups are possible. Expansion, interproximal reduction,
extraction patterns, etc. Once you decide on treatment, then Orametrics
provides indirect bonding trays with brackets of your choice and archwires to
get from beginning to end with least change. Imagine the effect of knowing
from visit to visit how much tooth movement has taken place (and if it is in
the proper direction). This would require scanning at each visit, but think
of the possibilities. My two sons and I have a bet as to whose treatment
protocol will more quickly achieve the finished result. Also, we will
determine if 2 week or 12 week intervals are better (or something in
between).
It appears we have a dichotomy, Invisalign or Oralmetrics, but maybe they
will survive side-by-side. What a wonderful time for orthodontists! We have
never had the capability to micro-measure our techniques, but now it is
available. Who will survive? Wait for the next chapter of "Day of Our Lives
(Orthodontics)."
I think I have consumed too much wine tonight, but I hope you understand my
concept.
It was certainly nice to see all you computer "geeks" in Chicago.

set up Invisalign Centers around the country ( similar to Smile Centers =

Sincerely,
Roy King
Jupiter,Fl

I would like to point out that the introduction of "straightwire" 20 years
ago was viewed as a way to let the "general dentist's nose under the tent of
orthodontics." While it certainly has had an effect of making us less
exclusive, it really does not seem to be a major problem.

I predict that Invisalign will do something similar. Yes, it will have an
effect; yes they most likely will open Invisalign franchises; and for those
of you who thought they bought a franchise when you went through your ortho
residencies, welcome to the reality of modern business. Not just for ortho
is the world more and more competitive.

You may have noticed that Unitek has done very well since the Ormco bought A
Company. Unitek did not stand on the sidelines and say, "Gee, we already
have 20% market share. That's enough. Ormco deserves a chance also." The
Unitek reps worked the situation hard and converted two major accounts in my
area from Ormco to Unitek. That's business. I for one don't see a problem.

As far as technology taking over the market place, it was a great meeting. I
would love to have a Suresmile robot in the lab. If I could afford that, I
would stop buying large size gloves. Now that I think about it, I need to
run a cost benefit analysis on the cost of gloves vs. the cost of the
Suresmile scanner and robot.

Seriously, the world changes but not everything sticks. Some years ago,
Dolphin started as a way to eliminate xrays for cephs. We were all going to
scan our patients and create an "image" but not a ceph. Last I looked, no
one is doing that and Dolphin has metamorphisized into a more traditional
imaging company.

I also looked at the Serona (sic?) Digital Xray machine which involved CCD
technology. $55,000. That means $110,000 if you have two offices. Maybe
that will fly and maybe not. Great images but the CCD is very fragile and it
has to be physcially move from the ceph to the pan locations on the machine.
This means that it is going to be moved multiple times per day.

I asked the rep how fragile a CCD unit was since I had heard that was a
problem. She told me that they teach the DA's that they need to think of the
CCD as a newborn. In other words, no dropping allowed. For those of you
without OB-GYN trained DA's, $8,000 for a replacement CCD although you
probably can buy a rider for your insurance.

Still a great system with great technology except the patient has to stand
still for 14 seconds for a ceph. I have some young patients who can't stand
still for a 0.5 sec ceph. Time will tell. Actually, this will probably fly.

Anyone else care to make specific comments about things they saw.

I know this is a funny story but the reality of the market place is very
close to the first part of the story, not the second part. All I hear is how
hard it is to find an associate. This is a nightmare for the senior ortho
who truly wants to retire. He or she can't.

For work dogs like me, I intend to let my estate worry about the practice.

Not to sound ludicrous but what if one had to finish all of their patients and
then close the doors. Equipment was written off, building that they owned could
be leased for additional income or sold and one's savings would be used for
retirement (the way it was supposed to be used). So, what if you could not sell
that practice? Would it really be the end of the world? Are we really that
dependent on what we may or not sell our practices for?

Considering that most in the workforce do not own their own businesses but rather
work for someone else, how do they manage to live out their lives with no
business to sell at the end. Although the sale of a practice is everyone's
desire, is the thought of possibly not doing so the end of the world? Is it
worth selling to a MSO just in case?

I do hope that I have saved enough in the end that the sale of my practice does
not make a difference. We are part of a great profession that rewards us
handsomely. My wife has already told me that I am giving the practice to my kids
so I am planning on living off of my savings and not the value of my practice.
If my kids do not go into this great profession and I end up selling my practice
for a buck, the grandkids will be guaranteed a great education and I get to
splurge or make a few charities very happy.

In the end, if we do not bank on selling our business for retirement, our mindset
will be different and we will plan around it. Then selling it simply becomes
icing on the cake rather than the focus of our retirement. I know my financial
adviser never considered the sale of my practice part of our retirement plan.

What do I know? I am just a 10 year veteran with some distance between now and
then. Maybe I will change my mind when retirement grows nearer. I do know that
it is not a part of my retirement package at this point in my life. Goodwill is
great but sometimes difficult to sell. Hard assets' values may change but they
still have some value.

If the patient has a deep bite, I would suggest you to avoid any extraction, because, that will deepen the bite.

Dear ESCO Members,

Anyone catch the May 22nd issue of Time Magazine (p. 73)? They did an
article about the 10 hottest jobs of the next decade and the 10 jobs that
will disappear. Number six on the list of jobs soon to
disappear......orthodontists. Apparently these little, computer-generated
plastic things called "aligners" will soon make our profession obsolete.
Guess I should pull out and dust off the ol' resume. Alternately, I could
tear up my ortho certificate, practice as a GP, and wait for my friendly
Invisalign rep to come knocking.

TIME magazine's May 22 issue ran a story predicting the 10 upcoming hottest jobs and the 10 jobs headed for extinction (pp. 72-73). They mention orthodontists in the latter category, and base this claim on the advances in the industry made by the Invisalign System (created by Align Technology). Please read on for Align's response to this article, which reflects the company's position on this issue.
Thank you.

Dear TIME editors,

Your tongue-in-cheek article "What Will Be the 10 Hottest Jobs and What Jobs Will Disappear� [May 22] was an interesting read, but flawed in prophesizing the demise of orthodontists. I�m the President and Co-Founder of Align Technology, makers of the Invisalign System (you mention our aligners in your article). It�s simply untrue that computer advances will render orthodontists obsolete. While Invisalign�s ability to straighten adult teeth (through a series of removable, clear plastic aligners) is made possible by advanced 3-D imaging technology, the system relies on the diagnostic expertise and treatment skills of orthodontists to work.

Adults currently make up approximately 20% of all orthodontic cases, though an estimated 2/3 to 3/4 of the adult population could benefit from orthodontic treatment. Adults wanted an alternative to metal braces. Now, with Invisalign on the market, we expect many more adults will get their teeth straightened. More adults in treatment could actually mean we need more, not fewer, orthodontists. Already more than one-third of US orthodontists have been certified to use Invisalign. Invisalign is now available commercially across the US and Canada. For more information, readers can visit the website at www.invisalign.com.

Sincerely,

Kelsey Wirth

My reply:

I am the other end, Mark, having practiced almost four times as long as
your ten years. I don't own my building. I rent. My office is in an
expensive prime spot in my town. I have equipment that has not been
written off yet because it was bought only a few years ago. I try to
keep my technique up to date by going to clinics, meetings, etc. I
cannot see myself paying the overhead (rent, utilities, salaries, etc.)
I would have to pay to finish all of my patients. How can I afford to do
this when the last few patients occupy the time previously allocated for
several hundred? I do not depend on selling my practice for my
retirement.   I would like to choose and train someone who would make
the transition much easier for the patients, and for me. If I can get
some compensation for this, so much the better. With graduates looking
for the big time practice, I'm afraid I may be out of the loop. My
practice is small--less than 300 K/year. I am sort of at a loss to be
able to know how I might successfully make this transition. I wish it
were as simple for me as it apparently is for you. Orm

For all of those planning on attending the College of Diplomates meeting in
Halifax, please leave your deodorant at home or be prepared to be arrested

Charlie Ruff

    HALIFAX, Nova Scotia - Perfume is meant to provoke passion, but not the
sort stirring this
      historic seaport.

To the horror of perfume makers worldwide, Halifax has become the first
major center in North
America to prohibit the wearing of all cosmetic fragrances - from Giorgio to
grandmother's lavender
soap - in most indoor public places, including municipal offices, libraries,
hospitals, classrooms, courts,
and mass transit buses.

With little fanfare, and less public debate, a city renowned for its sea
breezes and friendly folk has
declared underarm deodorant, herbal shampoos, colognes, and other scented
products to be hazardous
to public health - or at least too politically incorrect to be countenanced.
The ban, backed by ardent
scent opponents, reflects not only concern for people discomforted by
fragrances but a grim new
environmental view that sees a morning slap of aftershave as a blow against
Mother Earth.

''Aromatic chemicals are poisoning people and the planet as much as tobacco
or pesticides,'' said
Karen Robinson, an anti-scent campaigner who compares the fight against
fragrances to writer
Rachel Carson's celebrated early warnings about the effects of DDT, a
powerful insecticide now
restricted by law. ''We don't want a `Silent Spring' brought by cosmetics in
Halifax. We've even got
scent-free doughnut shops.''

Meanwhile, students have been suspended from class for wearing hair gel and
other scented goo (one
nearly landed in jail for ''assaulting'' his teacher's olfactory senses); an
84-year-old woman was
booted out of City Hall for wafting her customary cologne while making a
civic inquiry; and another
woman was ordered off a city bus for smelling too sweet.

Private enterprise is joining the crusade with surprising alacrity. The
Chronicle-Herald, dominant
newspaper in the city of 350,000, has ordered its employees to refrain from
even ''strong
mouthwash.'' Other companies send perfumed or deodorant-wearing workers home
to a take shower,
deducting the lost time from their paychecks.

Critics are calling it the Halifax Hysteria.

''We're abandoning common sense in order to placate a small handful of
individuals bothered by
scents,'' said City Council or Steve Streatch, one of the few local
politicians willing to speak for the
record on what has become a highly emotional issue, with campaigners wearing
gas masks turning out
to jeer anyone opposing their view.

''People have been wearing fragrances since biblical times,'' Streatch said.
''If someone wears too
much, if they become obnoxious to people around them, then a friend should
speak to them. Or a
work supervisor. But bringing government into what people dab on their face
or rub into their
underarms is just too much like Big Brother.''

But anti-fragrance advocates hail Halifax as standard-bearer for a
burgeoning New Age movement.
In the United States, only Marin County, California, has displayed similar
zeal in combating perfumes
and other fragrances. But its ''ban'' on scents in civic places remains
voluntary.

''Almost alone, this good city up in Nova Scotia is showing the courage to
take a stand against
neurologically toxic chemicals guised as fragrance,'' said Fred Nelson of
the Michigan-based National
Foundation for the Chemically Hypersensitive. ''Canadians are showing an
empathy for victims of the
cosmetic chemical industry that seems to be lacking among Americans.''

At the heart of the hullabaloo is a syndrome called Multiple Chemical
Sensitivity, also known as
environmental illness. Sufferers claim that the ubiquitous presence of
chemicals in modern life has a
cumulative effect that causes some individuals to become violently ill at a
whiff of any scent, whether
Chanel No. 5 or Irish Spring.

The trouble is, most US and Canadian physicians and researchers refuse to
recognize Multiple
Chemical Sensitivity as a true organic disease. Specialists say some people
do suffer severely from
exposure to perfumes and scented cosmetics, but the reasons are poorly
understood and the reactions
- including headaches, vomiting, and seizures - do not appear to be caused
by genuine physical
allergies, much less poisoning.

By and large, mainstream epidemiologists and occupational health doctors
believe Multiple Chemical
Sensitivity is a complex psychological, or ''psychosocial'' malady.

''What's taking place in Halifax appears to be collective hysteria over an
illness that does not exist,''
said Dr. Ron House, an epidemiologist at the Occupational Health Center at
Toronto's St. Michael's
Hospital.

''The uproar is fascinating from a cultural view. But [the ban on
fragrances] isn't good medicine, it's
folly - political pandering to a few rather strident activists,'' he said.
''Sadly, the whole business leaves
Halifax looking more crackpot than compassionate.''

In a case that made world headlines, a 17-year-old student named Gary
Falkenham last month was
handed over to the Royal Canadian Mounted Police by officials at a Halifax
area high school after
showing up in class wearing Dippity Do hair gel and Aqua Velva deodorant.
His scent-sensitive
teacher, Tanya MacDonald, demanded that he be charged with criminal assault
for supposedly
jeopardizing her health.

''This is insanity,'' said Charles Low, president of the Canadian Cosmetic
Toiletry and Fragrance
Association. ''This teenager was threatened not only with expulsion but a
criminal record for wearing
deodorant.''

The RCMP dutifully investigated but finally declined to bring charges. ''We
can't ignore complaints,
but maybe this kind of thing is better resolved with dialogue,'' said
Sergeant Wayne Noonan.

The school backed away from demands that Falkenham be prosecuted, and
instead suspended him
for two days.

Nancy Radcliffe, columnist for the Halifax Daily News and one of the few
Haligonians to raise a
public voice against the fragrance ban, said Canada's famously civil society
has lately become far too
credulous when confronted by anyone claiming to be a victim.

''Our problem is, we're too darn polite,'' she wrote recently. ''We don't
want to inconvenience anyone,
so we're constantly giving up our rights because somebody claims it's
offending them.''

Manufacturers of scented products are stunned by events unfurling in
Halifax, where sales of scented
products have plunged 25 percent, according to local retailers. They are
most appalled that their
industry is being cast as a ''merchant of death,'' in a league with Big
Tobacco and gunmakers.

But cosmetics makers and perfumers may be in for a long battle. The
anti-scent movement appears
to enjoy some support beyond the hard-core activists.

''The rest of the country may think we are a bunch of crackpots, but I
believe some people are
canaries in a coal mine,'' Stephanie Domet, an editor at The Coast, a Nova
Scotia weekly, told the
Toronto-based Globe and Mail newspaper. ''We've created a world where some
people are overly
sensitive to chemicals. So is it really such a hardship for you not to be
able to pour on the Charlie?''

I see that the subject of retirement and disposal of an orthodontic practice has come up again and I would like to discuss my experience, having retired last year.

Dr. Grimes has put his finger on a very vexing issue: what to do if you have a practice that is modest in size.My own practice was not large enough to attract any buyers, so my solution was to decide on a retirement date and then work an additional two years, treating the income from that period as though it had come from a buyer. I then arranged with a nearby orthodontist to take over my practice at no cost to him. Obviously, he would have inherited my patients anyway if I had just closed my office. We had an arrangement whereby I worked in his office for a certain period of time, about 6 months, I think, getting my patients ready for the transfer. My building, which I owned, was sold without much trouble , but not to a dentist.

If I had had a million dollar practice it would have been easy to hire an associate to eventually take over, but with a smaller practice, you can't do that, as there is insufficient cash flow for that.

However, being aware of the situation for many years prior to retirement I made sure that I always made the maximum contribution to my Keogh plan. I can't emphasize how important that is. At present, thanks to that strategy, my retirement account has grown to the point where I make more income than I ever made doing orthodontics. So, as Dr. Lively has astutely pointed out, the disposal of the practice should not be the prime consideration when contemplating retirement. Hopefully with proper planning, the sale of the practice will just be the " icing on the cake", and can be ignored if it doesn't happen.

When I am at a dental meeting, if the topic comes up, I try to impress my younger colleagues to fully fund their retirement plans. I am always surprised with the excuses I hear from them. When they say    that they can't afford to do so, I say to them that they can't afford not to do so. Although they may not like to hear it, I suggest that they should forgo the new BMW or the boat until after the Keoghs and IRA's are fully funded.

The above takes discipline, but it can be done, and you will reap the rewards after retirement.

My reply:

I am the other end, Mark, having practiced almost four times as long as
your ten years. I don't own my building. I rent. My office is in an
expensive prime spot in my town. I have equipment that has not been
written off yet because it was bought only a few years ago. I try to
keep my technique up to date by going to clinics, meetings, etc. I
cannot see myself paying the overhead (rent, utilities, salaries, etc.)
I would have to pay to finish all of my patients. How can I afford to do

this when the last few patients occupy the time previously allocated for

several hundred? I do not depend on selling my practice for my
retirement.   I would like to choose and train someone who would make
the transition much easier for the patients, and for me. If I can get
some compensation for this, so much the better. With graduates looking
for the big time practice, I'm afraid I may be out of the loop. My
practice is small--less than 300 K/year. I am sort of at a loss to be
able to know how I might successfully make this transition. I wish it
were as simple for me as it apparently is for you. Orm

hey ormond, they never told us at wash u. that we had such a solely
unique future problem, unlike any in any other phase of the healing
arts. man, it is really tough out there and a huge concern, not just
expenses but possible refunds. you can't stop taking new patients if you
want to sell or bring someone in, and if you finallydecide to quit and
not take new patients, there is not much to sell if someone would come
along. this is not just from me but from almost all the other orthos i
talk to. amen to your words.

The California Dental Board has recently changed its requirements for
sterilization procedure. It now requires bagging instruments prior to
sterilization. This would seem to require me to change from a dry heat
sterilizer to either a cemiclave or steam autoclave. Does anyone have an
opinion about the pros and cons of these options?

I have read everything I can get a hold of regarding this issue because we have 7 high heat sterilizers (of the old variety) that will need to be replaced. I appears that we will receive a discount from Dentronix for our old machines, but the cost is still considerable. Additionally, the new sterilizers will not cycle as fast, nor will they hold as many instruments. The good news is that high heat is still the best for pliers. We will soon bite the bullet and buy more pliers and trade in our old sterilizers and move forward, awaiting the next costly regulatory change.

You retain complete control of your practice, utilizing only the concepts you prefer to implement. For a 17% service fee, you receive 100% of the last 12 months receipts, half cash and half in a 3-yr note yielding 9.5%. After 5 years, you can walk away if you wish. This is a "transition" scenario I sent to Ormand: Find an orthodontist in your area who is willing to join OrthAlliance. Include your practice in the deal. OrthAlliance will pay the orthodontist you locate one year's gross, 50% cash and 50% as a 3-yr note yielding 9.5%. The orthodontist can just pay the money to you as you walk away. He, in turn, gets the full 100% for his practice and then continues to work at his practice with your practice, as a satellite. His overhead goes up 17% but so does his income. Bottom line... you and he get cash, you walk away, and he makes a great income with an additional satellite office.

Here's another scenario that will give the retiring orthodontist about the same overall income at the end, but may offer other advantages. For example let's take a practice which grosses $500,000 a year and has a %50 overhead. With the OrthoAlliance option: The orthodontist recieves $250,000 cash and a 3-year note of the same value. Overhead now goes up to 67% per year. This gives the orthodontist an income of $165,000 per year for 5 years (assuming that billings stay the same). After 5 years, the orthodontist is $1.35 million ahead and can walk away. Who will take over patients...maybe OrthoAlliance finds a new guy to come in. The other option: The retiring orthodontist finds a young and growing orthodontist in the area. He offers his practice to him for $250,000 (about 15-20 % below market value) and to stay on as an associate at 40% of billings. The retiring orthodontist gets $250,000 initially plus $200,000 income per year (assuming he still produces $500,000 of billings). Or he could decide to slow it down, hence the new orthodontists practice grows. He also receives coverage from another orthodontist, security that if he has to leave the practice sooner than 5-years that there is someone to take over his patients and to work with a young orthodontist who may invigorate his desire to practice. (i.e. more enjoyable). All said and done, the retiring orthodontist after 5-years makes way with $1.25 million (only 100,000 less that OAlliance scenario) plus other benefits as mentioned above. The young guy also wins: he buys a practice for less than market value, the security of a long-established practice and referal base and also has an orthodontist for coverage...not to mention the extra 10% left over from the paying of associates fees. The overall overhead of the practice could also be reduced, especially is the retiring orthodontist's office is gradually joined into the young orthodontist's facilities (overhead of one office as opposed to two). It appears as a win-win situation.

Dr Vendittelli did a great disservice by painting a pretty picture for a retiring orthodontist. His picture of OrthAlliance is totally incorrect also.
First, OrthAlliance is not interested in signing up retiring orthodontists. The average age of the doctors is 47 and they are some of the most successful in the country. Although there must an exit to any contract, it is not the main reason for joining this company. Our exchange of ideas have allowed the doctors to grow their practices without working harder or longer. When a young orthodontist joins OrthAlliance, experienced OrthAlliance doctors will mentor him/her as the practice grows and they have 6 full-time consultants that work in the field to help institute practice improvement programs that are proven to work.
But if you simply want to look at the 5 year senario in dollars, with the OrthAlliance program, you must add 7% minimum interest for 5 years to the $500,000 which is over $200,000 in the bank and could be more even with diversified investment vehicles. OrthAlliance can help you find an associate and you can give him the practice, you have already been paid!! I have a large group practice in Atlanta and I have 5 associates. You are not going to find anyone smart to pay you $250,000 and make $50,000 coming in the door. Where does he get the money to pay the principle and interest on $400,000. Am I missing something here? Most retiring orthodontists have practices in areas of declining school age populations and are treating a select population that cannot be sustained by a young orthodontist without help. what are you going to do that you haven't done already that will make up the diference for him. Where does the help come from as you retire?   I don't see anything in your senario that is even near the value offered by OrthAlliance. Check your numbers and your potential associates and then call OrthAlliance.

Dear ESCO

If an orthodontist was not going to be certified by the ABO, is there any risk being certified by the NBO. The premise is that they are trying to mimic the rest of the medical profession. So the question is if you know that you are not going to take the ABO, then why not take the NBO?

I just read an article about some victims of the Los Alamos wildfire
disaster -- post-graduate students who lost three years of computer data
when their offices in field trailers burned up, setting back their
career plans. This sort of thing happens over and over -- people using
computers take for granted the safety of the data in those machines, but
when disaster strikes, they discover how vulnerable they were. Not long
ago I heard of an orthodontist in my area who lost all of his computer
data when his office burned. He had his staff religiously make backup
tapes, but left them in the office routinely! It's not rocket science.
Make backups, not all on the same removable media but rather on a
rotating batch of them. Take the backup tapes or disks off-site.
Always verify the backups by reading them back and comparing with the
hard disk. (A good backup program should do that automatically, but you
may need to turn on that option.) Better yet, have a spare computer off
site and read the backup into that computer. This keeps a spare
computer up to date for use at a moment's notice and it verifies that
the backup is readable by another computer. Even if you have a service
contract, the service people can't recreate your data from smoke.
Assume the worst, but prepare for it, too. I've used my own computers
since the late 1970's and have seen that everything that can go wrong
eventually will go wrong: hard disks fail, backup drives fail,
computers write faulty data, backup tapes can't be read back into the
computer when needed, power supplies fail and fry the computer circuits,
the backup disks were left in the direct sun and warped, etc., etc.

Just thought this would be a good time to remind everyone to back up
your data often, verify that the backup is useable, and take the data
off-site for safety.

Happy computing,

Dear Colleagues:
Don't let the media scare you away from attending the ABO in Halifax.
The "scent police" are not as pervasive as the media would have you
believe. I smell great and still wear deoderant....We are just
particular of the type of scent. Our #1 favorite is "Eau de Lobster".
Look forward to seeing you in Halifax.

Does anyone have any experience or thoughts to share about the Sony DSC

Camera Co. sells a nice, complete Sony package. Other than Dolphin, I'm

ESCO members,
Dr. Rosenberg recently asked about digital cameras. I have a question about digital camcorders. Has any one used them in orthodontic applications for their photo taking ability? The Panasonic PV-DV910 for example can take 750 still photos on a 60 min tape. It has an 18x optical zoom and 300x digital zoom. From what I've seen they can get very clear pictures, very close up, in low light. With index search so you can find your pictures and book mark so you can remove and replace partially used film and continue to add to it.These images can be saved on the computer and printed out or printed out on the digital photo printer. There seem to be several good, uncomplicated, rather inexpensive models to chose from. Just a thought. Forgive me if this has already been discussed, I haven't been paying close attention lately.

hello,

i just caught up on 20 or so ESCO and so my comments will ramble through
topics...
and please, I invite comments on the following...

first, to hit clinical stuff first and continuing the thread on avulsed
centrals...I am treating a patient w/ two centrals that were traumatized and
the patient would work well as a upper premolar extraction case...if the
upper centrals were questionable and you knew you had to take out two upper
teeth, would that sway anyone towards extracting the centrals rather than
risk taking out two premolars and then risking the loss of the centrals...

second, regarding missing mandibular 5s (2nd premolars ) and ankylosing
Es...has anyone out there done a vertical osteodistraction in the premolar
region to augment the bone for implants a few years down the road...I saw
this done for the anterior mandible at the AAO Meeting in Chicago using a
tooth-borne distraction device that was ligated to the cortical bone and
then slowly distracted the bone vertically to create bone for implants...it
looks like a better bone augmentation approach than a graft...

third, as a resident closing in on graduation...Ortho Cntr of America offers
$85k and $115k as a starting point for the first two years...that would mean
the standing offer is currently $100k a year for a warm body with an
Orthodontic degree...and by the way, every practitioner out there I know
thinks this is a bad deal in the long run, so you do the math...
also, I often talk to our instructors (Saint Louis U has about 20-25
part-time clinical instructors and others who teach) about this...my
metaphor is to imagine how cheaply you, as a hiring orthodontist, could put
me in a satellite office...well, that's how much it would cost me, plus I
could delay paying for anything for a year because every dealer will give me
a sweetheart deal...why would I pay one year gross for your practice?? or
even net??
lastly, there are more retirees than graduates and that means this is a
buyers' market...

fourth, along the same lines as above, despite some of what I am reading, I
don't personally foresee an actual shortage of orthodontists (except for
full-time academic roles) because most residents now see 250-300 starts a
year (grossing $750k plus) as average to small...we may be wrong, but its
our perception...OCA promotes that its practices start, on average, 450
patients per orthodontist, I believe...so what do you guys think, because if
there are fewer of us and our practices are not larger than those in the
past, we are heading for a shortage...

fifth, along the lines of dropping a patient...if the patient is a minor,
then they are a third party beneficiary to the deal and the fact that the
paying party broke their contract with you does not let you off the hook
with the third party beneficiary...that's what several lawyers I know tell
me...in addition, if the minor is paying, they still cannot be held
responsible for the contract, however you can be held responsible to your
part of the deal...these are basics of contract law, to my knowledge...

again, I invite personal remarks to smoronsg@slu.edu

Dear Club Members,

At the risk of being ostracized for ignorance, I have a basic question to float around. Why would you routinely articulate your study models? I know orthodontists that routinely mount all their cases, but get a foggy answer why. We know that occasionally there is difference between CO and CR and know that this knowledge may affect our treatment plan But my question deals with all the other times. For your information I am board certified and have been in practice for 18 years. I am wondering if I am missing something.

If you believe, as I do, that enlarged tonsils and adenoids have an
adverse effect on the posture of the tongue and mandible, especially if
nasal breathing is compromised, then this item found on the Internet
will be interesting. It describes a way that surgeons can use to shrink
hypertrophic tonsils without removing them. A radiofrequency
heat-generating probe (I think one brand has been called a "Hyfrecator")
is inserted into the tonsil and small amounts of heat are generated.
The killed tissue shrinks as it heals, thus shrinking the tonsil to a
more normal size. It's a new application of an old device. Since it is
quick, safe to do "in the chair" instead of in the hospital, and has
less risk than excisional tonsillectomy, it holds promise for a way that
oral surgeons can help us deal with those patients that have
malocclusions secondary to hypertrophic tonsils.

Dear Club Members,

At the risk of being ostracized for ignorance, I have a basic question to float around. Why would you routinely articulate your study models? I know orthodontists that routinely mount all their cases, but get a foggy answer why. We know that occasionally there is difference between CO and CR and know that this knowledge may affect our treatment plan But my question deals with all the other times. For your information I am board certified and have been in practice for 18 years. I am wondering if I am missing something.

Dear Colleagues
    This procedure is being touted for snoring. It also "shrinks" the palate
and ENT docs started pushing it about 2 years ago. I had this procedure done
to help me reduce a snoring problem.. I annotated in toto the procedure on
my website at drted.com. You can even see the progress chart I made with my
snoring problem..
At the home page click on the link "somnoplasty to eliminate snoring" at the
bottom of the page. Cordially, Ted :-)

dear smoronsg,

I read your post on esco about OCA, etc, and felt compelled to respond. I am
an independent, solo, private practitioner, 45 year old male, 16 years out of
ortho residency. It concerns me that so many residents are considering OCA or
other mso's as a viable entry vehicle into private practice. it strikes me
from my perspective as being short sighted. Yes, the starting salary is
tempting. I would have been tempted, too. Perhaps like you, I was in
substantial debt when I finished school. I bought a practice for a year's
gross, and had a few lean years as I paid my debts and my practice note.
More importantly though, I steadily turned the practice into what I always
wanted. Now I have a large, state of the art practice with an income I
wouldn't have imagined when I was in school. I am not tethered to a
"management" company. Rather, I can hire consultants as I feel needed, and
have no strings attached. My practice is just that, with 50+% going into my
family's pocket every year.
If you guys would look beyond the first few years, you will realize, as many
consultants have astutely pointed out, that you will earn substantially less
over your practice lifetime affiliated with an mso. Why do that? It defies
logic. Sure, the first few years are easier. But aren't you gutsy enough to
venture out on your own and call your own shots? I believe that you will
become very weary of paying the "management" fee after a while, realizing
that you are the one busting your behind every day to please patients and
parents and keeping staff happy. Don't think for a minute that OCA deals with
and solves your staff management problems for you. The concept of coming to
work every day and only treating patients, leaving management to OCA, is
wishful thinking, in spite of what their recruiters may say.
This is a great profession, and I hate to think of it turning into what
optometry has become. Corporate America sees orthodontics as a profit
center, understandably so, and OCA is looking for young residents to make
money for them. That's not why I went to school. How about you?

Dear Scott:
    On June 17, you wrote to the mailing list some thoughts as a senior
orthodontic resident nearing graduation. You asked "Why would I pay one
year gross for (a) practice?? or even net?? . . . Lastly, there are more
retirees than graduates and that means this is a buyers' market." You
went on to explain that "Orthodontic Centers of America (OCA) offers
$85k to $115k as a starting point for two years ..."
    As an orthodontist 28 years in private practice, approaching
retirement, I offer some counter-thoughts.
    I looked into OCA several years ago. The starting salary is not
truly a salary. Rather, OCA guarantees that you'll be paid that amount,
but during the ramp-up of a new practice, your practice will be in
negative cash flow. OCA loans the practice the money it needs to get
going: construction, equipment, supplies, salaries, advertising, and
your personal salary, . . . to cover the negative cash flow. The
practice accrues interest debt to OCA on the loan balance. OCA shows
you spreadsheet projections that make certain assumptions, albeit based
upon experience from other practices they started, but still they are
projections and estimates. Your mileage will vary. If you start so
many cases per year, you'll ramp up so fast, reach positive cash flow in
month "X", and start paying back the loan to OCA. Meanwhile, OCA is
sharing the practice income with you, since they "own" half of the
practice, and you pay them a fee for their services to the practice.
The contract is non-cancellable by you except if OCA fails to perform
(but by what criteria, and would you be in a position to take OCA to
court to enforce your disappointment with their performance, would they
say it's your fault that the practice didn't meet the projections?).
Study that contract and get competent advice.
    Okay, so you weather the ramp-up period. Now you are working an
established practice that is bleeding out cash to OCA to pay for its
corporate profits (remember the stockholders expect return on
investment) and for corporate salaries and limos, etc. Who controls
those expenditures? OCA has a 20-year locked-in contract with the
practice, with an option to renew for 20 more years. That's surely
longer than you'd want to be working, so basically, this is indentured
servitude. Maybe you'd be better off with a Big Brother running your
show because you don't want to manage your own office or don't think you
can do it, but most of us went into dentistry to be our own boss, not to
be a cog in a wheel. And remember, OCA isn't in that office, dealing
with the staff as people, dealing with the patients, doing the treatment
-- it's you. They'll help you because they want the office to succeed,
but you're still the one where the buck stops.
    If you buy a small practice by your scale, say one grossing $500k,
well run, with an existing well-trained staff in place, all knowing
their jobs and working like a machine, you can have an overhead in the
50% to 55% range, more or less. Let's say 55%. You net 45%. That's
$225k net to you, before debt service. Let's say you draw $115k per
year, as you say that OCA offers. That leaves $110k per year for debt
service. If you pay the seller $350k for his practice and finance it
all, how long would it take you to pay off the loan? I don't know the
current loan rates and I don't want to take the time to be precise on
the estimate, but my spreadsheet says you'll pay it off in about 3 years
9 months at 12% per annum paying $110k per year. You can do the math.
    At that point, you'll own 100% of the practice. If you want a
practice management consultant to help you, you can hire one for just
those services you feel you need. You can fire them, shop around for a
better service, do without them, whatever. It's your show. Moreover,
you aren't paying for the lease on the corporate headquarters and the
corporate salaries and perqs and the shareholder dividends. As you
said, there are lots of orthodontic suppliers competing for your
business and you can get good deals without OCA. Moreover, supplies are
only a small part of your overhead.
    Meanwhile, you are building your practice on top of the one you
bought. You can do almost anything that OCA can do for you, without the
hooks attached. Besides, the best practice builder is your personal
contact with people, especially your referrers or potential referrers.
OCA can't do that for you. Any techniques they have, you can do, too.
    When nearby older orthodontists with shrinking practices decide to
retire, you can buy one as a satellite, already in positive cash flow.
Pay a reasonable price. Maybe even pick up a bargain. I've seen some
advertised. You can be the consolidator, instead of OCA.
    Sure, you can go the route of OCA and its like, but don't disregard
the advantages of taking over a private practice already running,
without a ramp-up, with a trained staff, systems in place, a workable
office space, a recall pool, prior patients who bring their kids in and
refer their friends, good relations with referring doctors, etc. You
can gradually remake the old practice to your own desires, updating
equipment and redecorating, while you earn an income. And it will be
100% yours, and you call all of the shots.
    And OCA isn't all that smart. One OCA office I visited was using a
kitchen counter-top convection oven as a substitute for an FDA-approved
sterilizer.   Who would take the blame on that when a malpractice
lawsuit hits over an alleged cross-contamination infection?   That's
right, the doctor with the license, not OCA. Another was designed with
the sterilization station way in the back of the office, making the
assistants walk the length of the office to recycle instruments after
each patient visit, whereas the x-ray and darkroom were centrally
located to the operatory although they are only needed a few times per
case. Where is the expertise that office layout?
    Final thought: I don't think you're right that there are more
retirees than graduates, not yet. The boomer bulge will reach
retirement age soon, but many orthodontists like to continue working
longer than you may imagine. When they finally are retiring in greater
numbers than new graduates emerge, who'll take over the patients of the
practices that don't sell? Practices will consolidate, or disintegrate
and the neighboring offices will pick up the patients. There will be
fewer practices, but they'll be bigger. Get ready. Get a practice.
You can succeed. You know it. Do it.

hello again,

i thought i would clarify three things about my previous posting...

1) i am NOT considering OCA...i appreciate the advice, but a monkey could
figure out that OCA is not the way to go (apologies to all those associated
with OCA, but capital is not in short supply for orthodontic graduates)
2) i base my assertion about practice size of 250-300 patients as medium to
small based upon discussions with faculty and private practitioners...the
ones doing less than 250 consider themselves not at full capacity but they
are STILL QUITE SUCCESSFUL...i want to iterate that size of practice should
be a function of practice philosophy, not the basis of measuring one's
success...
3) my comments on practice values can be further explained...if fair market
value of the practice is one year gross, then in a buyer's market the value
decreases...and i know people who have been looking for a purchaser for
years...and others who have no problem...

by the way, i appreciate the great responses....but i'd rather not mislead
anyone into thinking that i would even contemplate OCA...i get enough junk
mail as it is...

Jim,
I find that after mounting all cases there is no other time, that is, I
am unable to determine by looking in the mouth what the type of
discrepancy is and the amount. Only by mounting casts are you able to
determine the character of the discrepancy. It may be horizontal or
vertical or both, and you cannot tell by manipulating the mandible. Most
slides that appear to be horizontal are in fact vertical problems, and
this can markedly alter your treatment.
Philosophically, I believe that mounting your cases in the best centric
relation of the day allows one to diagnose and therefore treat to a
seated condylar reference position. Doing so has helped me reduce the
amount of problem cases I have in my office.
I also found that when I tried to pick the cases to mount, often I
missed something, but when I started mounting all cases, then the amount
of information available in the study cast increased substantially.
And finally, from a purely practical standpoint, mounting cases is
quicker, easier, and less expensive than polished, white stone models
with a great deal more information available.

Dear Members,

I am useing curing light with Apollo 95E lite Plasma Arc.
I think that it is good. However I feal that some materials need curing time
about 6 second.
Other some materials need curing time about 1-3 second.
but I don't have information for curing time.
I want to some information for curing time for some bonding materials and

I know a few of the people here have been doing it for years. They
led me to start mounting models and I am thankful for their guidance.
Had I not been part of this group (ESCO) I think I would not have
changed.

Me, I've only been mounting models for a bit over a year.

The occlusion is (remarkably) more accurate regarding the overbite
and buccal relations. Models ground with a wax bite I now regard as
bordering on fictitious.

Plus it is (a little) cheaper and frees my staff up. It is easier for
the staff to get this right than model trimmer models.

You are proabably right, much of the time it makes little diference
but already I have a couple of patients where the diference from
mounting is significantly different to hand held models. I know I can
hear arguments already as to why it should make no difference. IMHO
it has made a difference.

In a decade or two I expect the publication standards for changes to
occlusion induced with orthodontics will need to be measured off
mounted models as hand held models will not have (it never has had)
adequate reliability and accuracy to measure for example the change
in molar relations in mm between pretreatment, deband and
posttreatment. This accuracy is required if a meaningful
interpretation of postreatment crowding, overbite and overjet changes
is desired.

So James, I am not saying you are wrong or your records are poor or
deficient just that for me I think there may be a better way.

Dear Stan:

Great piece. I have been in practice now for 10 years and for the past
7 I have been in solo practice. I bought an existing practice, will be
making my last note payment next month and do not regret it. I paid one
years gross and it was worth it. I started out with a great income from
day 1, was my own boss, bought into an established referral pattern, the
dentists in the area became familiar with my work immediately, I ran the
show and use consultants as needed.

I did better than the OCA salary from day one and most should be able to
beat this if they are looking to buy a practice rather than going in as
an associate. I gave the original ortho 3 months to do aquatint me with
all patients, treatment plans, intro to dentists and familiarize myself
with remaining tx plans to remaining balances. It worked out great and
I was an immediate owner of my own business.

I cannot imagine doing it any other way. Starting from scratch has its
advantages(not treating someone else's patients) and disadvantages
(starving). Going with OCA may work well for some but I cannot imagine
that a soon to be graduate would not be smart enough to examine this
from all sides. The second year resident sounded more like a paid
solicitor for OCA. He was totally clueless and obviously frustrated.

Do the math, you cannot lose paying someone one years gross if you
simply buy out the practice from day one. The banks will finance part
of the purchase and the owner will usually finance the other half.
Great deal and great income from the very start.

Mark

I have been doing lingual since 1980 and there are no short cuts!!!! The

This is a deep philosophical question (or religious, if you prefer). To my knowledge, there is no research to support the efficacy of *routinely* mounting models, so the motivation must be (as mentioned below) sales and marketing (implied superior technique and $$ for the guru teaching the technique)...or.....because it makes me feel good. There *is* scientific evidence to suggest that you can equillibrate CO and CR, but whatever means...ortho, surgery, diamond, green stone, cranial suture manipulation, whatever.....but they (CO and CR) won't stay "synchronous" over time. For all the science in the AJODO, it's amazing how many orthodontists are susceptible to dental cults. There are cult members who believe the temporomandibular joint looks like working portion of an articulator. You might call them "technologists". There are others who view the temporomandibular joint as a biologic structure...complete with metabolism, variability, change over time, etc, etc. You might consider them "biologists".

Chuck Greene (of Laskin and Greene fame) suggested that we have the TMJ olympics...complete with teams and uniforms. Each cult would field a team and compete for superiority on a *scientific basis*. If there was a clear winner, they would be awarded the TMJ gold medal. If there was *no* clear winner (and I suspect that would be the case), we would go back to doing what feels good and hopefully not harming patients.

My mentor has suggested that some orthodontists go through practice life transitions which he calls the "senile decline". The first stage is a developing obsession with occlusion and TMD diagnosis. This usually culminates in the second stage, which is buying a series of "5 speed" articulators and all the associated paraphernala to mount cases. One can generally "recover" from the first two stages. The third stage is an obsession with nutrition, complete with organic supplements, hair and fingernail analysis, in-office counseling, etc. To his knowledge.....NOBODY has recovered from the third stage.

Dear Club Members,

At the risk of being ostracized for ignorance, I have a basic question to float around. Why would you routinely articulate your study models? I know orthodontists that routinely mount all their cases, but get a foggy answer why. We know that occasionally there is difference between CO and CR and know that this knowledge may affect our treatment plan But my question deals with all the other times. For your information I am board certified and have been in practice for 18 years. I am wondering if I am missing something.

A kinder and gentler approach might be laser UPPP....assuming that the level
of obstruction has something to do with tonsils. Generally, they are so
atrophied in adults that they're a non-issue. I hate to think what they'd
do if the level of obstruction is determined to be the tongue. :-)

I guess I would start conservative and see if one of the plethora of
"anti-snore" appliances was effective. There is some science out of British
Columbia on this approach for those interested in science.

I wouldn't recommend them. I had them installed when I first built my
present office. Only one remains in a consultation room. The provide
monofocal light and are worthless for seeing the lower arch in a reclining
patient. It's too easy to block the light source with your hands. The
parabolic reflector on conventional lights has a purpose...and that's to
provide a light source that's uniform and hard to block with your hand(s).
I've installed conventional lights on all the units. I found that the
double banks of fluorescents don't quite do it for eyes past age 40.

I tested many of these camcorders, along with most digital cameras as they
hit the streets ... bth for myself, and the sake of others that take my
courses or ask.

It is true that you can get OK picture quality, as you noticed, and can
append voice notes during the seconds that the image is frozen while the
tape continues to record, and that you can get many images on one tape.

I have a digital camcorder (Sony PC-100) and find that iti isn't too
difficult to go through the tape either (I have a SONY Vaio laptop with
i-link that fully controls this process in the camera by remote through the
program in the VAIO ... you could also use MotoD-V interface and software in
a regular computer).

BUT

1) There still won't be correct color and saturation in the images without
ideal lighting (unless you build color-corrected white LED video lights like
I have for other docs)
2) The standard is now assumed to be greater than 400 lines resolution, and
you will lose more after you crop.
3) You may get tired of downloading
4) you will need a close-up lens to be far enough away from the subject
(except full-face views)

Which means what you suggest (with a few mods) makes a great mid-treatment
records acquisition camera, and a great introduction to multimedia fun, with
less $$ outlay.

It used to be that there were very few digital cams that had a decent enough
lens to do ortho pics (100mm equiv), but lots of DV cameras did. Now there
are some exccellent choices out ther, that with few mods, will work.

I bought the SONY PC-100 because I wanted video and stills in one camera. It
has a megapixel still, that shoots through a fast Zeiss lens, and a flash
shoe and mating flash, that wih a #2 close-up, puts you far enough away from
the subject that there aren't any flash problems (unless you are doing model
pictures with a flash?). This makes for a simple off the shelf system that
also allows me to take videos of my kids and grandaughter.

If you don't need video, consider the older olympus 200 or Nikon 950 or
Sony DSC D700L ... all of which are heavily discounted, but work well with
the close-up lens on (Olympus needs a special adaptor tube). The Sony needs
a special flash system unless you use the LED ringlite. The new generation
are even easier to use and better, and, surprisingly, not much more $$$.

This may seem a horrible, mercenary way of thinking;
when you routinely mount models it is easier & faster
than producing trimmed, soaped, polished "orthodontic"
models.
And fee guides allow a higher fee for mounted models
than for orthodontic models.
So they cost less for staff to produce & you get a
higher fee? Hmmmm... let me see.... tough decision.
And of course they do provide more information about
CR-CO. Didn't that mildly experienced Dr. Roth say
once-upon-a-time; "never believe what you see in the
mouth"?

Hi Denise,
I think we all face this type of problem. Rather than try to solve the
dilemma yourself, it is probably time to contact your workman's comp carrier.
You can do this to discuss the situation and they will give you advice and
probably suggest a clinical exam by one of their doctors. You may be going
down the path of no return with this employee, so be careful what you say and
do. You may also want to discuss the situation with your other employees to
determine their position on the issue. Make sure that all your office
systems are in order: Osha, Wage and Labor, Sterilization, Duties performed
by office staff (especially BackOffice), and cash handling procedures. It is
far better to be prepared and act, than unprepared and react.
Good Luck,
Ron Redmond

and I apologise for the unfinished letter. As mentioned, I have a

anyone aware of any articles in the literature regarding this situation?

Dear Kim:

When you say European Orthodontics, exactly what are you describing. There is an ortho in my town that sells the parents on the "European Technique". He advises them that it is used and Europe and his cutting edge. He then delivers a bionator a few weeks later.

Hello Montanan,
We all do! There was a difference in the "old" days, but today all
orthodontists use very similar techniques.
Good Luck,

Mark,
You are the exception and not the rule, and you did not move to a
metropolitan area. And you did not build out a new office to start. The
silent majority out there are having a hard time getting started, not only
do they struggle in getting a good lease, getting a good buildout, and
marketing themselves, but they need mentoring. They have no money and very
little experience. Orthodontics is so good that you can fail and still
partially succeed. That doesn't mean that you do as well. MSO's and
especially OrthAlliance give the new graduate a wealth of resources that are
not available otherwise. And OrthAlliance is an group of independent
orthodontists that have joined together to help each other grow, whatever
the goals of the individual orthodontist. Check out the differences.

A little knowledge is dangerous! Unfortunately, I know a little about a
lot. Readers beware!

After 22 years of experience using a Quint laminagraph, I have read and
listened to various opinions questioning the validity of TMJ tomos. My
experience with these films has been excellent especially when used and
interpreted correctly while realizing their limitations...as any other
diagnostic tool.   I've also taken numerous, but certainly not all,
occlusion and TMD courses over the years. I am a proud owner of two
articulator systems----which adorn my lab shelving most of the time. Please
don't take me lightly since I own 3 & 4 articulators of each system along
with the variators and other devices. We do occasionally use mounted models
when deemed appropriate--such as open bites and surgical cases.

As a result of the above, I have more questions than answers.

The real question and dilemma is who can scientifically define and document
the TRUE CENTRIC RELATIONSHIP? What is Centric Relation? It was different
for the earlier gnathologists than most currently held beliefs. Is it
possible that centric relation might be the wrong position for SOME finished
cases? Perhaps, centric occlusion is best for that particular patient. Is
there true data that supports any of the myriad of mandibular manipulation
and mounting techniques? Are there studies that demonstrate accurately and
without bias what the actual condyle position is for any given manipulation
technique? How can the techniques all be different and correct at the same
time? If one religiously mounts their cases, does that mean they are saying
a prayer that the condylar position is correct? Has anyone ever verified
the condylar position radiographically for a their definition of centric
relation? Or is this highly significant subject being addressed anecdotally
by our authorities and leaders? (I suppose we could ask similar questions
about amalgam.)

What about growth? What is the normal condyle-fossa relationship in a
growing child--or adolescent? When is the joint fully formed? What changes
in joint morphology occur with various treatment modalities? Do we have the
mechanics to fully treat to our perceived mounted-models-treatment-plans in
a realistic fashion for all of our patients?

When models are mounted, how do we know where the condyle really
is???????????????   And if we do, then how do we accurately duplicate the
movements of this complex joint with flat articulator sufaces? And where is
the disc especially in clicking patients? And how do we compensate on our
mounted models for disc displacements, perforations, and adhesions?

I believe that I know some of the answers to these questions but would
rather hear your responses. If any of you would be kind enough to provide
me with valid references, I would be most appreciative.

Thank you,

I know a few of the people here have been doing it for years. They
led me to start mounting models and I am thankful for their guidance.
Had I not been part of this group (ESCO) I think I would not have
changed.

Me, I've only been mounting models for a bit over a year.

The occlusion is (remarkably) more accurate regarding the overbite
and buccal relations. Models ground with a wax bite I now regard as
bordering on fictitious.

Plus it is (a little) cheaper and frees my staff up. It is easier for
the staff to get this right than model trimmer models.

You are proabably right, much of the time it makes little diference
but already I have a couple of patients where the diference from
mounting is significantly different to hand held models. I know I can
hear arguments already as to why it should make no difference. IMHO
it has made a difference.

In a decade or two I expect the publication standards for changes to
occlusion induced with orthodontics will need to be measured off
mounted models as hand held models will not have (it never has had)
adequate reliability and accuracy to measure for example the change
in molar relations in mm between pretreatment, deband and
posttreatment. This accuracy is required if a meaningful
interpretation of postreatment crowding, overbite and overjet changes
is desired.

So James, I am not saying you are wrong or your records are poor or
deficient just that for me I think there may be a better way.

To Robert Pickron, OrthoAlliance member

Dear Robert,

I would like to make the following counterpoints to your ESCO post regarding
new graduates and mso's. First, who ever said it was going to be easy
starting your own orthodontic practice? The best things in life never are.
Certainly, as you say, there are challenges in getting a good lease, getting
a good buildout, and marketing your practice. And yes, new grads need
mentoring (I still do, too), but don't sell them short. The point is that
new grads are equipped to handle these and other challenges, and will be
seasoned by the process. I find the language you use, like other mso
supporters (mso members, of course), plays on the fears and insecurities of
residents. Ortho residents are the best and brightest people in dentistry. I
trust that they will see through the mso sales rhetoric and resist the
temptation of an easy start, and instead holdout for the superior rewards
(financial and otherwise) that true private practice holds. As for
mentoring, there are great consultants available who are very capable of
helping you get going in the right direction, and advising you along the way
to stay competitive in any market. In short, you don't need to become
chained for life to an mso to achieve a successful practice. Mso's are
looking for new grads to make money for them, and as I've said before, that's
not why I went to school.

I am very much in line with Dr. Lively's comment regarding the choices available to recent graduates. I spent ten years in banking and now 21 years as an orthodontic consultant. Start-up money, and lots of it, is available to new orthodontists. In fact, there are very few people that bankers would rather lend their money to and, from the lender's perspective, there are few better reasons to borrow money. Start-up capital is not a problem.

It does take some courage, some self-confidence, and a willingness to be at risk, to start your own practice and/or to borrow money to build or purchase a practice. However, the net income will be there, in time to pay the school loans, the bank loans, and with enough left over to take a decent salary. Once those loans are paid....... We have 500+ orthodontic clients, some are "old-timers" and others are recently out of school, but all started from "scratch." None of them, not even one, would trade his or her experience.

As I wrote a couple of years ago, the MSO experience is right for some doctors, but it would be a serious mistake for a young graduate to believe that participating with an MSO is the only realistic choice he or she has.

Hi,
    I guess the part I have trouble understanding is why articulated
models are more accurately related, upper to lower, than are ground. It
seems to me that the bite registration is all that could be different.
If one uses the same bite registration technique then I can't see what
the difference would be. That is unless, of course, the articulated
models are set up with protrusive and lateral check bites. What is the
point of doing that for T1 ortho where you expect the occlusion to be
changing? The whole mounting issue seems to me to be much more sensible
for pre-T2 so you can look for interferences and function.

Nicely stated! And it's gratifying to see the "indoctrination" from the
various courses didn't cloud your ability to ask the important questions. I
sometimes think the cosmic significance of joint space and condylar position
is a discussion best held at the bar over adult beverages. It seems like
you've found the path of reason despite having multiple articulator systems.
Was it Lysle Johnston who defined gnathology as "the study of how
articulators chew"?

Denise Lawry >>

Denise,

The advice I am going to give worked for me in the US. Things (laws) may be
different in the land of Crocodile Dundee so check with your attorney or
check with your Workman's Comp carrier as suggested by Dr. Redmond.

I've had this happen to me twice in 20 years. Once it was a front desk
person and then it was a clinical assistant. I've always taken the approach
that staff are long term investments. I've seen colleagues take a different
tack with staff and it tends to be more confrontational that way.

Assuming your staff are long term investments, you might start by asking your
Workman's Comp carrier for advice. I did not do that. I asked a PT I was
friendly with for her advice on the issue. She told me that she wanted to
make a site visit and observe the front desk employee at work. She felt that
she might be able to make some suggestions regarding work habits, work
posture, etc. In fact, she made one site visit and suggested that the staff
person needed more support for her wrists and forearms while doing data
entry. She recommended a chair with special forearm supports that would cost
around $800 (8 years ago). I was delighted to have that info and doubly
delighted when she suggested that my Workman's Comp carrier might pay for the
chair as an "injury preventer." That is exactly what happened. The staff
person is still with me and while she does not do quite as much data entry as
she used to, she works with a computer 60% of her day with no recurrance of
the problem.

The other situation involved my lead chairside assistant. She basically did
everything and was always willing to jump in and do more than her fair share
if someone was falling behind. She started to complain that if she did
several debands in a day, her wrist would hurt afterwards. She attributed it
to removing composite with a carbide tipped bond removing plier. She felt
this repetitive motion was the cause of the problem.

Interestingly, her dad is a machinest and she and her dad are constantly
making things together. She has made a custom canoe with dad as well as a
sea going kayak. At the time she was experiencing problems in the office,
she was also doing a lot of custom basket making with a friend. Obviously,
this is a person that likes to stay busy and use her hands as part of her
hobbies.

She and I talked it over. It was clear to me that she was a career oriented
DA and she did not want to leave the office or be forced to leave. We tried
to modify her duties so she did fewer debands in a day. Her limit seemed to
be one or occasionally two. She also came to realize that basket making was
not helping the situation so she stopped that on her own. Again, she is
still with me after 5 plus years and no additional problems. She is now
clinical supervisor. And we no longer remove cement with a carbide tipped
plier.

My suggestion is to take people at face value. When I teach on staff
management, I frequently use the expression, "Expect a lot. You will rarely
be disappointed." I believe that and it seems to be an attitude that works
for me.

I have just bought a Nikon Coolpix 990 digital camera. I am trying to
figure out how best to use it for intra-oral shots, but the learning
curve is steep!

Has anyone in the group any advice? Either direct settings etc., or

The point flash built into the camera is excellent and provides aesthetic shadowing that a ring flash won't give. If you find the right cheek casting too much of a shadow, you can either pull the camera back a little bit or flip it upside down to get the point on the other side. 9) Normal distance from subject is about 8 inches. Purchase your left thumb on the camera (near the flash) and your pinky on the patient's cheek/chin.

For the right side, I hold the camera upside down to have the flash in the mouth instead of the cheek's shadow. Only the front (smile) shot is taken without the flash. Since the sequence is always the same, I have built a macrocommand in Photoshop to process all the pictures at the same time with only one click of the mouse.

They are both 3.3 million pixel cameras and the prices are similar. My planned usage is for general photography (mostly home photography) with occasional use as a back up clinical camera. We recently purchased a Minolta RD 175 as our main digital clinic camera (just starting the learning process) but I anticipate that inevitably there will be some breakdowns and a backup may be needed. One obvious difference between the two cameras is the positioning of the flash relative to the lens. This seems like it would be significant when one is using the camera for close up applications. I am an absolute rookie in anything to do with digital photography and I'd deeply appreciate any feedback on these two cameras.

Thomas and Lester Kuperman and Craig Andreiko cannot be answered by writing as well as by experiencing the differences between model trimmer centric and articulator centric. All I can state is my own experience. I first went to a GP course on occlusion which opened my eyes to my own ortho problems, and realized that I knew a lot about alignment and zero about dynamic function. As I grew to learn articulators, I realized that while imperfect, they allow us to visualize a problem in three dimensions better than any other method. So I mount cases on a simple Whip Mix articulator (developed by Niles Guichet as a simple method of analyzing casase before mounting reconstruction problems on his "big box" Denar fully adjustable instrument). As Craig says, initial mounting doesn't require as much information about condylar inclination, etc., as that required to construct crowns or bridges. But it IS a three dimensional recording unlike hand held models. I was heartened a few years ago to hear Larry Andrews explain his disposable articulators as sufficient for ortho because we really only need to capture the terminal relation. Exactly. All the angles and curves are immaterial because we are going to move the teeth. But, we must know where we're heading. Without a map, it's just a guess. So while some are content to argue, others have found true utility in having a more accurate diagnostic tool which cuts our error rate immeasurably. Once one learns to mount cases, one realizes that the majority of class II cases have significant vertical interferences which can be seen and demonstrated and replicated and felt. As the mandibular cast is moved against the maxillary member, it is possible to see the condylar member separate from the eminence. Why bother? Because this is what occurs in all of our patients. They are not just a set of teeth. Articulators are simply a method of visualizing the problems of occlusion more fully. If one carries the disbelievers logic to conclusion, why make models at all. We have the teeth to view in vivo. And why record the positions now since we're going to move thenm anyway? I have been contemplating a one day hands-on course for orthodontists with assistants which would teach simple case mounting on an inexpensive Whip Mix articulator system (not because there aren't other good systems, because that's what I know). Is there any interest for such an endeavor?

I apologize for the length, but it seemed indicated. Why are articulated models more accurately related, upper to lower, than are ground models? It should be very clear to all that they are not more accurate. However, something should be said for the handles. As a method of evaluating the relationship between upper and lower casts, the articulator mounting has many advantages over the unrelated, ground casts. If the interocclusal record is removed, as must be done to evaluate tooth contact, then transverse discrepancies and relations are lost. If there is contact on only the posterior teeth, then evaluating that is difficult at best, while the models are positioned on the bench. Viewing the lingual relations in a more realistic vertical position is impossible unless there is some type of mechanism to relate the upper to the lower cast. In this case, if one subscribes to a seated condylar reference position, then utilizing a technique to capture the �hinge axis� is important. For this the hinge becomes an integral part of the evaluation. Bite registrations are the only difference. Quite true, the importance of the �bite registration� is important. However, one must be aware of the limitations of the centric bite of the day. Each technique is operator sensitive, and it is not a skill that one achieves without some practice. Reproducibility is difficult at best and requires skill and practice, mostly practice. Use of lateral and protrusive check bites. If one chooses an instrument which only follows straight lines, then these procedures will seem adequate. If the true border movement of the mandible is important for the success of the treatment, then these will not be sufficient, and at best could only give an indication of the functional movements which are being portrayed. Mounting at T2. Assuming this is at a time prior to appliance removal, this would have to be another ideal time to observe. If one could avoid problems by observing earlier, is there no value in that? Why would one wish to limit the information available? Indoctrination and clouding ones abilities. Indoctrination from various courses and abilities to ask questions. Does this suggest that those who find value in mounting cases have been indoctrinated and are only following the guru? Perhaps this represents utilization of the scientific method as originally proposed. Observation is a part of the scheme, is it not? Definition of Gnathology An operational definition of gnathology might be the measurement of how the tops of the teeth move across each other, and how to design a system which will allow movement without detrimental collision. It is obvious that articulators do not chew, and that most humans are not rigid structures that move in straight lines. The articulator is a tool, nothing more. Some find it useful, and after having it help to provide satisfactory results with our treatment, choose to use it as a measuring instrument. None of us, who follow a clinical path, want less than the best for our patients. These gnathologic concepts have helped refine that which we do on a daily basis. The fallacy of using tomographs as the basis for utilizing or not utilizing mounted study casts. Viewing a two dimensional representation of a thin slice of a structure gives credence to the concern the clinician has for the integrity of the structure, but beyond that, the relationship is less clear. In making the decision to mount casts or not, TMD may be a factor, but only one. The value of the technique does not rely solely on its ability to identify a �disease state�. Owning machines: The fact that several systems have been purchased over the years, could suggest several things. Different systems do some things better than others, and this could be a reason. Things have improved, and with time we learn and choose systems which serve us better. A better use for usable systems might be donation rather than adornment. Questions: What is Centric Relation and has it changed? It would appear that the meaning, and what that represents has not changed. The semantics have and the precise wording has been altered, but what is represented has not. The condyle has always been viewed as being most stable when it is positioned against the eminence with the disk interposed and from which position all movements of the mandible could be made. Centric Relation wrong for some finished cases. If there is no disk, if the morphology of the system will not allow this, then perhaps one could suggest that centric relation coincident with centric occlusion might not be the best for the patient. In the absence of pathology, that is, a healthy joint, it is difficult to understand how a position of stability would be detrimental. Is it better to learn to treat to the what if case, or to the healthy case? The answer would appear obvious. Mandibular manipulation and mounting techniques: If the reason for utilizing these techniques, is the achievement of a reference position, then utilization of observation, hypothesis formation, testing, and corroboration would appear to provide the necessary verification and data sought. It is suggested that if a reference position is located, then the method that is used to capture that relation does not matter. Perhaps the methods necessary to achieve this position need further refinement, but the repeatability of such a position in the hands of skilled clinicians suggest that it is possible. In other words, centric is centric is centric. Religion, Prayer and mounting cases: Methods are available to test the reliability and reproducibility of the techniques, and they have been published. With more sophisticated measuring tools, will these techniques be shown to be inaccurate? Almost certainly! Is one doing the same when no measurements are taken as compared to using a standardized approach? Again the answer appears obvious. Condylar position radiographically in centric relation: Why would one technique with as many inherent variations as tomography, be held as the gold standard for evaluation of a position over another with equally as many variables. Perhaps the ease with which one is obtainable, and the ability to visualize what appears to be a good representation has deceived us. It may be possible that both techniques offer advantages, and useful information. The future may provide better methods of obtaining the information with less effort, but until that occurs, testing one against another may obscure the value of both. Growth and the normal condyle-fossa relationship: Change and increase in size occur. Our patients generally grow larger. Yet, has anyone suggested that more basketball players could be produced if we held the surfaces of the knees apart? There does appear to be some semblance of order with regard to the workings of the parts. The �closed packed� joint appears to remain as that which has the best opportunity to function. Function is the operative term�movement. Centric or the seat Condylar reference position is just that, a place that can be returned to for evaluation. To interject these other questions, only clouds the issue�why mount casts. Mechanics available to treat to the plan: Assessment of this question requires the reference against which to judge. Unfortunately, unless the same records are taken prior to treatment and then after, and then compared, the answer will elude us. For some, there is sufficient evidence that mounting casts is one method of assessment. Again, observation is the key. Articulators duplicating movements: The gnathic system is not made up of flat surfaces, and to use a system which is unable to duplicate the movement one is interested it makes little sense. Does this mean that there is no valuable information available with such instrumentation. If the limitations are recognized and accepted, then much is to be gained. If one expects to hold a fully representational model of the skull in one�s hand, then disappointment awaits. TMD, discs, clicking: Do not all of these suggest pathology or at least alteration of structure? Should the clinician expect to be able to avoid taking these changes into account when treatment is contemplated? If in only one case, the use of a technique can more accurately represent the condition, is the effort wasted? If the technique has been thoroughly investigated and discarded as useless, then please disclose the reasoning. If on the other side, others find value, with little increase in risk for our patients, then what is to be gained by casting aspersions. Which leads to the final comment: Valid references: What constitutes references which are acceptable, and who deems them valid. Is the Scientific Method really defined by double blindedness. Observation and testing would still seem to be part of the scheme. The goal of the profession should be to improve, not tilt windmills. If a segment of a profession utilizes a technique, finds it useful and valuable, and produces results which corroborates their hypotheses, then isn�t it incumbent upon the profession to at least look over their shoulders and try and duplicate that which appears to be working? Thank you for your persistence. I speak only for myself, and my experiences. I have found this to be a valuable tool, and I believe it has made my practice better and my life easier.

Craig Andreiko In a previous posting I suggested that ground casts probably give much of the clinical information most of the time. You asked where differences between hand held and articulated models might be. IMHO if wax is being used for the bite registration and grinding then even the best lab will return the models with the bite a little different as the pressure and vibrations distort the wax. This would be why mounted casts would be more accurate. Other bite registration materials will be less susceptible to creep (I use silicon). I agree that I usually am going to control each and every erupted tooth in full banding so pretreatment interferences are invariably going to be moved so the pretreatment prositions are not as relevant but then again if you take your logic further, if we are going to move all the teeth then why bother with casts? I believe it is to see what we started with. Hand held models are a an unreliable means of determining pretreatment overbite especially in open bite and incomplete overbite cases. Your point about T1 and T2 is most reasonable but I aslo found that as my wax bites distorted they were more likely to return ground nearer to CO than CR and when held by hand they were also more likely to move towards CO with both giving a false view of the problem to be addressed. Maybe these problems were issues within my office alone (and every uni department I have ever seen which used wax bites) but these problems have been cured for me now that models are being mounted. But hand held models look and feel prettier. Please yourself and don't mount models, I see this as one of the smaller improvements I have made to the way I work in the last few years. I am sure I could return to hand held models if I had to but I would prefer I did not. Yours, Mark Cordato Bathurst markc@ix.net.au Date: Sat, 08 Jul 2000 15:54:02 -0500 From: "Kevin C.

If that's what you're looking for it's simply a term used by the weekend hotel orthodontic lecturers (not to be confused with educators) to make their "students" somehow feel they are learning a superior form of orthodontics. Many European orthodontists are educated in the U.S., do they practice differently than we do? What you want is an AAO member and preferably one that is ABO certified (ABO certification won't guarantee a better practitioner but there is a certain amount of effort required to become certified). Mounting models? Cheaper, OK. Higher fee, all right... but providing more information about CR-CO? And "never believe what you see in the mouth."?! Do you mean to say that mounted study models with all of the inherent errors induced in the transfer process, distortion of impressions, etc., give you a better picture of the patient than a clinical exam? Just because someone teaches something doesn't mean it is so. Experience doesn't necessarily make someone correct. For thousands of years the Sun revolved around the Earth. If mounting models is cheaper and more profitable, I'm all for it. But if you are telling me that mounted models allow you to make a better diagnosis and, more importantly, get a better result, where's the evidence to support this?

It was in response to a posting about OCA. He has advised me that no one that he has contacted felt that his post was pro-OCA and that most residents are very much aware of the pitfalls involving MSO's. He advised me that the only negative responses were knee-jerk responses from the "older orthos". He also advised me that he has successfully purchased a practice and is not going the way of the MSO. I was also very happy to hear this and advised him that if one is willing to roll up their sleeves and struggle for awhile, they will find it to be a worthwhile experience. Ortho is such a great career. He also advised me that the older orthos were responsible for the current state of affairs for not paying graduates what they deserve to be paid as associates and for not helping with the financing. Based on his comments he was speaking for most residents. I thought I might pass this along to those hoping to find the right person to take over their practice. If this is the state of mind of most residents then you might be working longer than you were hoping. I was also advised that insulting someone has no place in an intelligent conversation. I have to agree with this and so I do apologize for my rude remark. If I am a representative of the "establishment" I hope that I have not been an embarrassment to you and I also apologize to my colleagues for my remarks.

Maybe it will have some impact, but I am not ready to run up the white flag. After 20 years I can still count the number of patients treated successfully with removable appliances on one hand. Patients will comply with something that doesn't impact appreciably on their lifestyle. They will wear a retainer at night.....sometimes. Few will wear something 24 hours per day, especially for the period of time to achieve the desired and detailed changes. Time, of course, will reveal the truth of this, but I think the metalo-orthodontists don' t have to panic just yet..... Paul M.

They are both 3.3 million pixel cameras and the prices are similar. My planned usage is for general photography (mostly home photography) with occasional use as a back up clinical camera. We recently purchased a Minolta RD 175 as our main digital clinic camera (just starting the learning process) but I anticipate that inevitably there will be some breakdowns and a backup may be needed. One obvious difference between the two cameras is the positioning of the flash relative to the lens. This seems like it would be significant when one is using the camera for close up applications. I am an absolute rookie in anything to do with digital photography and I'd deeply appreciate any feedback on these two cameras.

My experience with lower incisor extractions has been favorable using
immediate initiation of space closure following extraction and with
rapid closure. I have been able to finish with a good amount of tissue
interproximally in what was the extraction site and the bone has looked
good radiographically.

But the current case in question has an almost full-size, erupted,
supernumerary, maxillary central incisor. The tooth in the midline is
to be extracted because of its form and caries. A consulting
periodontist has suggested that the bone be allowed to fully reorganize
before the adjacent teeth are moved into the extraction site. I fear
that a long wait will result in loss of both alveolar height and
thickness and thereby cause a larger interproximal space in this
aesthetically critical area.

Any thoughts? Please relate your practical experience (or reference to
any articles) as to the speed with which anterior extraction spaces can
or should be closed without causing problems to the periodontal
ligaments.

Hi all,
    I have a very nice, well adjusted, above average, twelve y.o. boy with a terrible gag reflex. We have gotten thru records and extractions but bonding has been very difficult. I have tried several different retractors trying to avoid placing anything on the roof or floor of the mouth (these areas seem to precip. an unwanted reflex). I am considering using a glass ionomer cement so moisture control will be easier. I was able to get brackets 3I3 and separators today without incidence (mom not feeding him prior to the appt is also a plus), next week is bands, then place lower bonds later. Any suggestions? drugs? hypnosis? Any and all recommendations welcome.

The Shape of PCs to Come?
Department: Technology & You
The new Qbe tablet computer from Aqcess Technologies (www.qbenet.com) may be a harbinger of shapes to come. The Qbe relies on data-entry technologies that aren't quite ready for prime time and is further handicapped by some poor design choices, but it is an interesting design pioneer.

The Qbe Cirrus that I tried is a box about 14 in. long, 10 in. wide, and 2 1/2 in. thick. The top is mostly covered by a 13.3-in. touch-sensitive display, and there's a built-in video camera at the top. The Qbe runs on a 400-MHZ Pentium II, features a 12-GB hard drive and 128 MB of RAM, and costs a steep $4,745. The less expensive Celeron-powered Genus model fetches $3,995. Both use Windows 98 and run standard PC software.

The Qbe is designed to be used on your lap or any horizontal surface. It stands up with a removable prop called a "porticle," which includes a full complement of parallel, serial, and other ports. With the prop and a keyboard and mouse attached, the Qbe is basically a variation on the desktop PC. Used as a tablet, however, it's something quite different from either a desktop or a notebook.

The problem is entering data. The Qbe offers three choices, none fully satisfactory. First, you can write on the screen with the pen, using ParaGraph's PenOffice software. Unfortunately, handwriting recognition doesn't work a lot better than it did in the days of Apple's much-ridiculed Newton. In the case of the Qbe, the accuracy problem is made worse by a noticeable delay before the writing actually appears on the screen. Having the option of a more accurate shorthand, like Palm's Graffiti, would be a big help.

The second method is to use the speech-recognition software included with the Qbe--Lernout & Hauspie's Voice Xpress. It does pretty well after you invest some time in training, but to get it to work I had to use a Telex digital headset to bypass the apparently defective audio system.

The final method is typing on a touch-sensitive keyboard that can pop up to cover the bottom quarter of the screen. The keys are big enough to hit with your fingers, and while touch typing is out of the question, the keyboard works well enough for limited amounts of data.

COOLER, CHEAPER. Beyond the data-entry problems, the Qbe has some design issues. At six pounds, it weighs heavy on your lap, especially since the Pentium heats the magnesium case up to an uncomfortable temperature. The Qbe can run on battery power, but only for about 90 minutes at a time, so you won't want to get very far from a power outlet. And this is a device that really wants a wireless connection to the Internet, since the tablet design is ideal for Web browsing.

Better, lighter, cooler, and cheaper tablets are on the way. Aqcess hopes to have a three-pound, $1,500 unit this fall. Later this summer, Qubit Technology plans to ship a much-delayed 2 1/2- pound Web-browsing tablet featuring a wireless link to the Internet.

Hi all,

Last year I purchased an Olympus D620l (1.4 mp) camera. I have been
extremely happy with this model. It is a SLR (thru lens focusing) camera,
reachargeable batteries, screw on macro lens with flash diffuser, and a
built in flash. Photos are very good even in the medium quality setting. I
know this is not a 2.4 mp but has it has served me well. I wonder why
Olympus has not made a high mp SLR camera? Or do they? Are the download
times with a high mp camera greater than the increase in picture quality?
Anyone have a comparison b/n quality in picture and download time. -- Does
it make a difference? I am downloading thru a floppy adapter -- which can be
slow. Is anyone using a built in drive that accepts the flash cards? Where
can you get one ? $$? Too many questions? All the best.

Hey Guys: Why all this talk about the CoolPix?

I did my homework over several months and last month took delivery of the
BEST digital clinical camera I have ever had, to replace my aging Fuji 220.

I bought a SONY DSD D770. It is a single-lens-reflex camera, auto or manual
focus, completely programable or manually selectable, came with a ring flash
which can be switched down to 1/16 power output for intraoral..in all...its
is supurb.

Unlike the Olympus 2500, the Sony can be used in EITHER viewfinder mode, or
on the screen mode...while composing. Has instant playback.

I purchased mine from Dolphin ...no financial interest.

Have a look at the Sony: you will be pleased with what you see.

Dear Member

I found Desital Camera for intro-Oral Photo.
It is Fuji Fine Pix 2900Z with Original Ring Leight.(about 1800$)

It can take a picture with X1/2-1 intra-oral photo.
I hope that I take intra-oral photo and facial photo(x1/10).

Please sent some information.

I just bonded a patient on Thursday who was born premature. He has been
intubated approximately 38 times over the past 16 years and has
difficulty swallowing food. He and his parents desperately wanted to
have his teeth aligned so we agreed to do the treatment.

No models were taken, only x-rays. Photos were next to impossible. We
managed to get cheek stretchers in, more than I was hoping for. As I
have in prior cases, we bonded all teeth with FUJI and light cured. I
spoke with mom again last night and he is doing great and all brackets
are still in place. Could not have done this without the FUJI OrthoLC.

Forget drugs.
1. Patient seated upright, not lying.
2. Cotton rolls with flavoring, not bonding frames.
3. Glass ionomer cement for bands.
4. Theta Dri-angle triangles over cheek salivary ducts.
and all will go well.

My experience with lower incisor extractions has been favorable
using
immediate initiation of space closure following extraction and with
rapid closure.  I have been able to finish with a good amount of
tissue
interproximally in what was the extraction site and the bone has looked
good radiographically.

But the current case in question has an almost full-size, erupted,
supernumerary, maxillary central incisor.  The tooth in the midline
is
to be extracted because of its form and caries.  A consulting
periodontist has suggested that the bone be allowed to fully reorganize
before the adjacent teeth are moved into the extraction site.  I
fear
that a long wait will result in loss of both alveolar height and
thickness and thereby cause a larger interproximal space in this
aesthetically critical area.

Any thoughts?  Please relate your practical experience (or reference
to
any articles) as to the speed with which anterior extraction spaces can
or should be closed without causing problems to the periodontal
ligaments.

Hi all!

For those interested in the Eureka Spring and its source, there was an
article entitled "The Eureka Spring" in the July 1997 issue of
JCO, page
454.

The source of the spring is Eurika Spring Company, 1312 Garden St., San
Luis
Obispo, CA 93401.

Do you think information management in orthodontic offices will use devices like the one below? Another innovation is in screen technology. Check out www.trivium.com/news/crains_june2000.htm Those interested in Trivium, financially can contact Mr. David Kinsley at 1-914-767-0431. Ron ParsonsLawrenceville, GA The Shape of PCs to Come?
Department: Technology & YouThe new Qbe tablet computer from Aqcess Technologies (www.qbenet.com) may be a harbinger of shapes to come. The Qbe relies on data-entry technologies that aren't quite ready for prime time and is further handicapped by some poor design choices, but it is an interesting design pioneer.

The Qbe Cirrus that I tried is a box about 14 in. long, 10 in. wide, and 2 1/2 in. thick. The top is mostly covered by a 13.3-in. touch-sensitive display, and there's a built-in video camera at the top. The Qbe runs on a 400-MHZ Pentium II, features a 12-GB hard drive and 128 MB of RAM, and costs a steep $4,745. The less expensive Celeron-powered Genus model fetches $3,995. Both use Windows 98 and run standard PC software.

The Qbe is designed to be used on your lap or any horizontal surface. It stands up with a removable prop called a "porticle," which includes a full complement of parallel, serial, and other ports. With the prop and a keyboard and mouse attached, the Qbe is basically a variation on the desktop PC. Used as a tablet, however, it's something quite different from either a desktop or a notebook.

The problem is entering data. The Qbe offers three choices, none fully satisfactory. First, you can write on the screen with the pen, using ParaGraph's PenOffice software. Unfortunately, handwriting recognition doesn't work a lot better than it did in the days of Apple's much-ridiculed Newton. In the case of the Qbe, the accuracy problem is made worse by a noticeable delay before the writing actually appears on the screen. Having the option of a more accurate shorthand, like Palm's Graffiti, would be a big help.

The second method is to use the speech-recognition software included with the Qbe--Lernout & Hauspie's Voice Xpress. It does pretty well after you invest some time in training, but to get it to work I had to use a Telex digital headset to bypass the apparently defective audio system.

The final method is typing on a touch-sensitive keyboard that can pop up to cover the bottom quarter of the screen. The keys are big enough to hit with your fingers, and while touch typing is out of the question, the keyboard works well enough for limited amounts of data.

COOLER, CHEAPER. Beyond the data-entry problems, the Qbe has some design issues. At six pounds, it weighs heavy on your lap, especially since the Pentium heats the magnesium case up to an uncomfortable temperature. The Qbe can run on battery power, but only for about 90 minutes at a time, so you won't want to get very far from a power outlet. And this is a device that really wants a wireless connection to the Internet, since the tablet design is ideal for Web browsing.

Better, lighter, cooler, and cheaper tablets are on the way. Aqcess hopes to have a three-pound, $1,500 unit this fall. Later this summer, Qubit Technology plans to ship a much-delayed 2 1/2- pound Web-browsing tablet featuring a wireless link to the Internet.

Hi all,

 Last year I purchased an Olympus D620l (1.4 mp) camera. I have been
extremely happy with this model. It is a SLR (thru lens focusing) camera,
reachargeable batteries, screw on macro lens with flash diffuser, and a
built in flash. Photos are very good even in the medium quality setting. I
know this is not a 2.4 mp but has it has served me well. I wonder why
Olympus has not made a high mp SLR camera? Or do they? Are the download
times with a high mp camera greater than the increase in picture quality?
Anyone have a comparison b/n quality in picture and download time. -- Does
it make a difference? I am downloading thru a floppy adapter -- which can be
slow. Is anyone using a built in drive that accepts the flash cards? Where
can you get one ? $$? Too many questions? All the best.

Hey Guys: Why all this talk about the CoolPix?

I did my homework over several months and last month took delivery of the
BEST digital clinical camera I have ever had, to replace my aging Fuji 220.

I bought a SONY DSD D770. It is a single-lens-reflex camera, auto or manual
focus, completely programable or manually selectable, came with a ring flash
which can be switched down to 1/16 power output for intraoral..in all...its
is supurb.

Unlike the Olympus 2500, the Sony can be used in EITHER viewfinder mode, or
on the screen mode...while composing. Has instant playback.

I purchased mine from Dolphin ...no financial interest.

Have a look at the Sony: you will be pleased with what you see.

They make a 2.5 Mp SLR, the C2500L. Usually the viewfinder version of their
camera is released before the SLR version, so expect to see a 3.3Mp SLR
soon. I can't comment on download times by direct cable, but using a
compact flash card reader which fits into the USB port takes about 90
seconds for 96MB, that's about 160 2.5 M pixel JPG's.

Mine cost about $120 Australian, about $70 US. I also bought a PCMCIA card
adapter which fits straight into the slot on a notebook for $25.

I use a Coolpix 990.

-In my experience the camera is extremely easy to use once you have
established your Manual settings for exposures. Resolution does allow you to
use the digital zoom beyond the normal tele.
-The camera is very portable (important for me to be able to take to the
o.r.)
-Image quality is satisfactory (I don't think anything can beat the qualtiy
of my 35mm Minolta bellows with Washington Scientific flash).
-I am glad I don't have to deal with a ring-flash (dull lighting and
ring-highlights on pictures), one of the biggest misconceptions in close-up
and macro-photography ("you need a ring-flash"), NO YOU DON'T WANT ONE.
-Viewfinder? I don't use it - I use the LCD screen which is basically TTL,
no problems here.
-Batteries? No experienced problems so far (2-3 months, 500 pictures), I
carry a second set of fully charged NiMH with me all the time (two sets of
NiMH and a 12Vcharger in the car), never ran out of power without backup.
-download time? What is that? I use a PCMCIA adapter for my laptop, there is
no download time, the computer reads the flashcard as drive E, access time
is as fast as I can imagine. I have never used the USB port or "god forbid"
the serial connector. Image sizes are typically a little over 1MB,
downloading must be a pain.
-card size? I use a 64MB Delrin, That gives me ca. 50 pictures at fine
resolution.
-how does it compare to other cameras? I don't know, screw on lens adapters
are not necessary though (=better optical quality and versatility), no
ring-flash (=better close-up flash, except you can't rotate it), small and
compact to carry (personally I like the rotating body, allows me to take
shots no other camera can).

That's my impression, I am sure this is not the camera for everybody, but it
is one of the better ones. I recommend it, it surpassed my expectations and
seems to fit my needs.

It can be found now, due to the new models, for about $400-500. It takes an ordinary floppy disc and on the medium size and fine setting will hold approximately 10 pictures(an orthodontic series of 8 easily). This allows my assistants to write the patients name on a piece of tape and label each floppy for later down-loading(no confusion with multiple patient down-loads). Picture quality is very good. Rechargeable 179min battery. Automatic focus setting is easy. Some quirks I have found: 1 I have taped a white paper label over the flash(which is set to on) to filter it's power. 2 The macro setting must be on all the time. 3 Because the flash is on the side of the camera it must be held upside down on the left buccal shot to not cause a shadow from the cheeck. 4 Finally I've found the best place for the zoom is just above the lightning bolt from the flash (if you have the camera you'll know what I mean). Has anyone tried any of the new Sony's.

Kaiser officials spent the past week calling all 858 members and apologizing, said Kaiser spokeswoman Beverly Hayon. "Some are upset," Hayon said of members' responses. "The vast majority have been gracious." More than 400 of the misdirected e-mails were intended for Kaiser members in California, said Hayon, who characterized the error as an isolated incident that has been rectified. "What we're talking about is nothing that breached security of Kaiser On-Line. No hacker, no virus," Hayon said. FUTURE CONCERNS Privacy experts, however, say the incident raises concerns about the safety of online medical services -- especially with the health care industry pushing digital medical care as "the new frontier" to cut costs and improve access, said Earl Lui, senior attorney with the Consumer Advocacy Organization in San Francisco. "It's an example of what could go wrong when you rely on technology rather than people seeing people. This would not have happened if these people had come in and seen a nurse or called a nurse," he said. "When you lose that human element, errors like this can happen." The error happened while Kaiser -- the nation's second-largest health insurance plan -- was doing a routine capacity upgrade of the online system, which is attracting 20,000 new members a month, said Anna- Lisa Silvestre, director of Kaiser Permanente On-Line. About 250,000 of Kaiser's 8 million members nationwide have signed up for the interactive site, which allows free access to health care news and chat rooms, as well as medical and pharmaceutical advice and appointment clerks. The site conducts about 8,400 transactions a month, mostly in scheduling appointments. A notice on the Web site assures privacy, reading, "We are dedicated to keeping your personal health information confidential. We take many precautions to make sure others can't pretend to be you and get your confidential information from this Web site." However, during the system upgrade, a technical problem occurred that interrupted delivery of about 8,000 e-mails, Silvestre explained. Since Kaiser Permanente On-Line has promised to respond to e-mail queries within 24 hours, technicians quickly wrote a program to resend the e-mails. On August 2, about 20 minutes after the send program was initiated, a technician noticed an error and stopped the transmission. WRONG E-MAIL ADDRESS Kaiser didn't know about the ramifications of the error until the next day when a member reported that she had received a response to her question -- along with messages intended for several hundred other Kaiser members. The member was one of 19 people who received 20 to 400 messages not intended for them. Kaiser said most of the e-mails were about routine matters. However, at least one of the e-mails was a response to a member's question about a sexually transmitted disease, the Washington Post reported. Kaiser On-Line is conducting a "root cause analysis" to determine the source of the problem, which will help determine procedures to prevent a similar mistake, Silvestre said. Because of lower costs, increased accuracy and convenient access to health care, online medical services are "the future of health care," said Sam Karp, chief information officer for the California Health Care Foundation, which funds health care research and did a landmark study on Internet privacy. While Kaiser's mistake "raised an alarm" concerning security and safeguards in online health services, Karp praised the HMO as a pioneer in the industry. "We're seeing the early pains of a new health care system emerging," Karp said. "I certainly hope the (Kaiser) incident won't discourage providers from offering (online services) or consumers from using it." Problems with privacy in the health care arena existed "before we had all these new technologies," said Daniel Zingale, director of the state's new Department of Managed Care, who also has high hopes for online health services benefiting the public. "Privacy is one area of legitimate concern, but it can be addressed," he said. "It's like the automobile industry. You don't want to stop building cars because of break-ins -- you want to build them with locks."

RE: Impacted molars without alveolus

Sounds like "primary failure to erupt". The only publication I know of on the subject is
by Proffit, in both a journal (I believe the AJO) and also mentioned in one of his texts.
It's tough to treat because the molars won't move and teeth posterior to the affected tooth
will also be affected. It's believed that there is a defect in the eruption mechanism.

Good luck,

Two comments: (1) Everyone does things differently. Different techniques,
different approaches and different speeds (times) to do similar procedures.
Better to monitor your own work habits and find average times for your
common procedures. (2) Ultimately you depend on other people (your patients)
to fall in line with your schedule. They don't know it; don't understand it
and have their own lives to lead in which they try to fit in your
appointments. And sometimes the weather blows your day all to hell! Get used
to the idea that the best schedule never works the way it's designed because
of outside effects over which you have no control. Relax. TGS.

This might sound like a strange request, but...

I need an orthodontist who fits all of the following:

    1) Board Certified (ABO)
    2) Practices in a pre-adjusted appliance
    3) Full start and strip records taken (models + ceph)
    4) 200 starts a year or more

You will have to do nothing except allow me access to your records.
Basically, I want to look at treatment time duration.

The ABO is for credentials, pre-adjusted is now the norm, I need the records
for comparison, and the 200 starts a year are so I can get the cases I need
to fall within a 5 year period in your practice (fewer changes in practice
philosophy).

At present, I can get 3 out of 4 easily with many practitioners, but I am
running into trouble getting all four.

If even remotely interested, contact me. I'll give you more details
one-on-one. If nothing else, you'll have someone give you alot more info
about your practice approach.

Hi All:

I am getting ready to make the plunge and convert to phosphorous
technology. I was ready to plunk down the $21K for the Dentoptix when I
received the brochure on Wehmer's Digident CR. It processes faster,
erases the screen during the process and costs $8K less. Is it too good
to be true or is the Dentoptix overpriced (this is a given)?

Any input would be greatly appreciated. BTW, I am not interested in
going to pure digital at this time so my choices are one of the above.

Thanks in advance,

Mark

Dear Colleagues,
    I have always resisted the tempatation to mount my cases on an
articulator. In fact I still have my H-2 Hanau from dental school (1965). The
only part that was misssing was the front pin which I ordered anew. Indeed
there in the "back" I even found the face-bow and bite fork. My staff was
bewildered and curious as to what the contraption was used for. Being a
teacher at heart I proceeded to explain the vagaries of habitual centric
occlusion as compared to muscular guided centric relation. I lold them how
the articualator was supposed to mimic the patient's jaws in relation to
their TMJ and how it could sometimes show up a patient's "true" bite rather
than the one the they us. That conversation led to talk about how error was
introduced when taking a wax bite on a facebow bite fork. Indeed I recalled
the need to "deprogram" the bite just before taking the bite. So I come to
you desiring to know how you "deprogram" the bite and the methods "you" use
to capture a centric related bite with a facebow bite fork. I am going to
show my staff just how much fun it can be.
Will you please refresh my memory regarding the specifics of these tasks.
Thanking you in advance for your kind help. Sincerly, old dog.

Dear Priscila,

I just opened the digest this morning.

As I recall the Eagle Sindrome involves the calcification of the
estilomandibular ligament. The estiloid process seems elongated in the Rx.
It will probably cause pain when opening the mouth. During the day I may get
some more info. You may contact me directly if you wish.

RE: Eagle's Syndrome
Eagle's Syndrome is an elongation and ossification of the Stylohyoid
Ligament. It can cause 1. Ear & throat pain 2. Sense of foreign object in
throat, 3. Pain on palpation
There is a high correlation between degenerative arthritis of the TMJ of the
same side and calcification of the Stylohyoid ligament on AP radiograph.
Sometimes the ossified ligament will fracture and continue to grow and the
radiographs show what appears to be bone as large as a finger with knuckling
(pseudoarthrosis) extending from the styloid process downward to the hyoid
bone. Sometimes you can see the calcification on a lateral Ceph. extending
from the styloid process to hyoid bone.

Hello Group

>>>A friend asked me about eagle syndrome, what is it, I remember reading
somewhere about it, its about a bone in the face that grows more than it
should and causes a lot of pain, but I don't remember which bone it is.
Can anyone help me?

Eagle's Syndrome, according to Jim Fricton, Co-Director of the Pain Center of
the U of Minnesota, is due to a calcified stylohyoid ligament. It usually
can be seen on a panoramic radiograph.

It mimics a glossopharyngeal neuralgia in presentation. Certain movements of
the jaw will trigger a sharp pain in the lateral pharyngeal area as the boney
ligament rubs on soft tissue.

Surgical excison is the tx of choice.

Warm regards

Styloid process elongation and calcification leads to glossopharyngeal
neuralgia...burning and strange sensations in the throat and neck when the
patient turns their head. Treatment is fracture or resection of the styloid
process.

Dear Priscila,
The Eagle's Syndrome has to do with the styloid process of the Temporal bone. It happnes when this styloid process growth more than it should, like a big nail, and the patient contact the tip of the styloid process with the interior anlge of the mandibule when opening. This might be painfull. I don't know how to treat this syndrome.
I hope this information will help you.
Sincerly,

Seem to recall the culprit being a calified Stylo-Hyoid Ligament that
binds when turning the head. I'm probably wrong but thought this
might be a start for you.

hi priscila,

eagle's syndrome: elongated styloid process and/or ossified stylohyoid
ligament WITH symptoms

you can search for eagle's syndrome at http://www.dentalmedline.com
at the search line type "eagle syndrome" (use the quotations marks...) you
will find about 114 publications on the syndrome... some of these
manuscripts can be ordered from the AAO's librarian...

Hello Group

A friend asked me about eagle syndrome, what is it, I remember reading
somewhere about it, its about a bone in the face that grows more than it
should and causes a lot of pain, but I don't remember which bone it is.
Can anyone help me?
Thank you

Dear group;

I would like to know what is your experience and opinion in dragging up
horizontally impacted wisdom teeth (upper and lower) to replace badly
carious or restored second molars (upper and lower) in an adult of late
20's. Overall dentition is of severe crowding in the upper and lower jaws
with poor long term prognosis of the second molars. What difficulties do
you normally encounter with uprighting horizontally impacted wisdom teeth?

I would also like to know whether there's any one out there in Huston who
practices lingual orthodontics as I have a patient who might be posted to
Huston, Texas for a period of years. I do appreciate if you could contact
me.

Once again thank you.

I hope to start treatment on a 12 year old with ameliogenesis Imperfecta -it
is the variant which has a very very thin layer of enamel but with minimal
pitting. - classic anterior spacing, small stubby central incisors etc. I
need just to align the upper anterior to maximize the chance for good
restorative options in the future.

Had any on successfully bonded such cases. If so what bonding system did you
use?

Dear Group members,
                                Dr. Levitt's kind attention is drawn to an
article in AJODO-1999(Dec)116:651-8"Eruption diturbances of the first and
second molars:Results of treatment in 43 cases":By Eduard
Valmaseda-Castellon et.al
        The results do not appear very encouraging, but still in such cases
where most odds are against orthodontic success, something is better than
nothing.

        Currently we do have two cases under treatment wherein all the three
lower molars on both sides are impacted.
                                sincerely,

Dear all,

I saw a NEW patient today (26 year old female) who has a history of
recurring Hodkins (Jaw /lungs).
She has in the past undergone extensive radiation to the jaw, prior to
which her third molars were prophylactically removed. She was then told not
to have any further extractions done for fear of poor healing etc.
She has also had "accelerated menopause" prophylactically induced.

She recently had a "Dexa test" done and was told that she has a significant
risk of developing Osteoporosis (?later in life).

ORTHODONTICALLY, she has upper and lower crowding which could be resolved
with fixed appliance therapy together with judicious interproximal stripping.

My question to the group is this:

"Are there any contraindications to treatment given both the irradiated
bone and susceptibility towards osteoporosis ? "

I would appreciate any thoughts/comments/experiences.

Thank you

Dear Colleagues:

I am wondering if any of you has had experience treating osteoporotic patients. We have a 55 year old lady about to start orthodontic treatment requiring maxillary and mandibular tooth removal. She has been told that she has the bone density of an 80 year old woman. She is controlling the osteoporosis through medication, and bone density scans have shown stability over the last 2 years. Any input or references on the subject would be greatly appreciated.

Thank you.

Priscila

Dear P,

First thought- you just finished tx and now your going to give him a
headgear? And you think he will wear it?
Second thought- if you knew he was class III, why did you treat him so early?
To have finished treatment on an 11 year old boy with class III potential
staggers my imagination. Why not let him grow and revisit around age 14 or
older to see how much class III and how much vertical is going to actually
occur?

This reminds me of a transfer case I just received. Same age as your
patient. In braces for a year and strong class III potential. Tall parents
and the patient had clearly not begun to grow when I first met him. Short of
cold steel, there is little I can do to prevent future class III growth.
Having the braces on for it makes it look like the underbite was my fault ---
"happened while he was wearing braces, doc" My treatment plan was to suggest
that the best approach in this case was to remove the braces and restart in
several years. Mother's comment: "Good, I always thought that other
orthodontist was too anxious to get the braces on."

Growth can help us in class II patients but not in class III patients. Why
make life harder than it has to be? Treat class II during growth and class
III's after growth. I'm not the brightest bulb in the lamp, but I figured
that one out.

Tengku:
It's been our experience that disto-angular upper 3rds can reliably replace
extracted 7's with little intervention needed. If they are mesio-angular,
they can be tough, but not impossible. Lowers, especially mesio-angular
ones with complete root development are a pain in the <expletive
suppressed>!

You mentioned severe crowding present--- assuming healthy joints that don't
need maximal posterior support, why not remove the 7's AND 8's and just
distalize to alleviate the crowding??

Just my 2 cents worth.......

Dear Escovians,
    All of us as orthodontists must at times convey information about the
need for bridges or implants to our patients. I recently completed (Sept 7th)
the implant-crown procedure on myself (9 and 10), and I fully documented this
experience including photos. I learned alot to say the least. It can be seen
at my website www.drted.com (Home page: "getting dental implant surgery")
You might find it useful to refer patients to this URL when you want to be
informative without mincing words: <A
HREF="http://www.drted.com/index.html/Getting_Dental_Implant_Surgery.htm">http
://www.drted.com/index.html/getting dental implant surgery.htm</A>   In
addition, I have just added to the site the "Informed Consent" for the one
hour tooth whitening which I offer in my office. For those of you are
considering offer that "profit center" to your list of services, it will save
you some effort by reviewing the one I provide to my patients. Here is the
URL: <A HREF="http://www.drted.com/index.html/teeth whitening Informed

I am currently treating a patient with ameleogenisis imperfecta. The
areas that have enamel hold the brackets just fine. However, I have had
a few brackets come off due to enamel chipping. Replacement of the
bracket on another area of the tooth has resolved that problem. I
recommend Reliance Assure bonding system(but I'm sure any system will
work). It is currently the strongest bonding system I know of and very
resonably priced (speak to Paul Gange).

Here in Northern California, in the Sacramento area in particular, our dental
society sent out a warning for a potential mail scam targeting dentists. I
personally got such a bill and after I gave it a second thought (and fished
it out of the trash) I gave a call to the BBB, but the line was busy
(probably other dentists doing the exact same thing!) It then sat on my desk
and then tonight I get this e-mail from my local society.
Watch what you write checks for! This is their warning (from the Sacramento
District Dental Society) :
"We have been contacted by several member dentists today about a bill for

waste collections for $49.00 on Account # 000177631 from "General Help,

Inc., 4809 Avenue N P.O. Box PMB 127, Brooklyn NY 11234. This bill has

the same account number on it for all offices it was mailed to and same

amount owing. It has been forwarded to the US Postmaster for follow up. We

would just like to have you spread the word to fellow colleagues."

On both occasions we bonded we there was enough enamel and banded bi's through molars where most enamel had stripped. Usually I would not bond on "thin enamel" , however, according the the IUSD Dept of Oral Pathology, most of these patients will need comprehensive restorative procedures as the enamel fails. Considering this, I'm not sure I would bond, as this may lead to earlier than necessary prosthetics. If the teeth are to be rebuilt soon after your treatment I don't see a problem with direct bonding. ---------- >From: orthod-l@usc.edu >To: Electronic Study Club for Orthodontics >Subject: ORTHOD-L digest 719 >Date: Tue, Aug 29, 2000, 9:34 AM > Date: Sun, 3 Sep 2000 02:23:58 +0200 From: "Peter De Wilde" To: Subject: Re: Amelogenesis Imperfecta Message-ID: <003a01c015e9$ba87d040$280a0201@peter> MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: 8bit Dear Karen, I am treating a family 3 childeren of which present with a severe form of congenital amelogenesis imperfecta. The eldest, a girl, terminated treatment 2 years ago. She originally presented with a huge Cl.II/1 deep bite malocclusion, overbite of 10 mm and 3 missing second premolars, projected on a skeletal Cl.I. The enamel malformation was apparent on all teeth, some of which showed spots of no enamel covarage at all. She was conventionally bonded with a no-mix adhesive (Relyabond). The brackets on the enamel deficient teeth came off almost immediately, an had to be replaced by cemented bands. The treatment of the second child, a boy with a similar malocclusion, is still in progress. In contrast with his sister he presents with an enamel pattern similar to the one you discribed in your pati�nt: a full coverage by a thin yellowish enamel layer with minimal pitting. After phosphoric acid etching (35%) a typical dull pattern of decalcification was clearly visible. His case was set up by means of a light cured adhesive (Transbond) and so far no abnormal bonding failures were recorded, apart from one that could be asociated with the extreme deep bite pattern. The youngest brother will get his braces in the near future. His teeth present with the same promissing enamel type as the older boy. So, without any doubt I will just glue them on!

I am about to embark on a software project involving "Automated
Cephalometric Landmark recognition".

I am curious as to whether there would be a demand for such software. I
have been following the research and papers on this subject for about 10
years and it appears that like voice recognition it may be more trouble than
it is worth. For example with voice recognition the "teaching" curve is so
steep that it is still easier to use a Dictaphone and a typist with some
good word processing/correspondence software linked to a practice/patient
management package. Not to mention the plethora of "manual" transcription
services that are now available on the net.

Given that you can now digitise and analyse a ceph within 5 minutes and
often a procedure that can be delegated to auxiliaries - would I be right in
assuming that Automated Landmark recognition would only be useful in a
research environ involving large samples?

Is anyone else working on such a project?

Dear Fellow ESCO Members,

This note is in response to recent postings by Dr. John Schuler and Dr. Vaughn Johnson regarding Invisalign.

I am the Chairman and CEO of Align Technology, the manufacturer of the Invisalign System.

Dr. Schuler's posting is inflamatory. Although his posting is in the form of a question, it implies Dr. Schuler's belief that Align Technology will not survive greater than two years and, as a consequence, the orthodontic profession will be left without Align Technology's support.

Perhaps Dr. Schuler is not aware of our organization. Briefly:

1. We employ over 1100 people worldwide, more than the top three orthodontic manufacturers combined.
2. We have over $150 million in capital with over $10 billion in additional financial resources available to us through our financial partners.
3. We have trained over 4300 orthodontists in the U.S. on the use of the Invisalign System.
4. Over 2000 orthodontists are already Align Technology customers.
5. We are the fastest-growing orthodontic company in history.
6. The vast majority of patients and orthodontists that have used the Invisalign System are highly enthusiastic about their experience.

Dr. Johnson's posting regarding our recent price increase could be interpreted as humorous, but, in the interest of clarity, I would like to state that our price changes were not in response to any balance sheet constraint. In fact, we have no outstanding material financial debts at all. Instead, our price changes were consistent with the costs of running our business and the current level of demand we are facing from our customers.

At Align we are doing our best to improve the selection of treatments that orthodontists can offer their patients. We urge our partners in the orthodontic community to support our efforts to help them. Inflamatory, reactionary or cynical postings do a disservice to the broader orthodontic community and are disheartening to the 1100 employees of Align. If there are legitimate questions about Align Technology or the Invisalign System, we would be delighted to speak to them directly.

Sincerely

Zia Chishti
Chairman and Chief Executive Officer
Align Technology, Inc.
Sunnyvale, California

Has any university done any basic research on how the teeth move with
invisalign, rate of movement, torque control, type of bone resorption
ect... or do we only get the invisalign clinical point of vue?

The people with the original venture capital investment. Has anyone looked at the stock trendline for Infocure lately? The corporatization of ortho and related services seems to be a tough row to hoe.

re: Invisalign

One good thing that has happened with offices that have signed
on with Invisalign is-       Vinyl Polysiloxane impressions-
We now use VPS for indirect bondings, Vacuum formed retainers,
and other dimensionally critical appliances.

You can't buy stock in Invisalign, but how about ESPE ???

In ancient history (1989-91) I worked with an engineering graduate student
from the University of Windsor on this interesting area. We found that the
techniques were feasible but that at that time the computer processing power
was inadequate and very slow. Things have changed in this regard.

He subsequently published his Ph.D. thesis.

We had a grad student working on that about 8-9 years ago. Never got it off
the ground. He's now teaching part-time at UCLA...or at least he was.

John,
Still seems pretty subjective as to how some landmarks are defined/located.
I expect that any automation may end up causing some grumbling about
definitions and locations. As long as the operator could "adjust" the
outcome by changing the location of various landmarks to suit them, I think
it may fly. I can't speak to the return on investment curve, but I'd imagine
that existing ceph tracing programs may be interested in incorporation this
technology into their programs. Good luck.

Thank you for all the responses over the topic.

Dr. Eric R. Brannon had suggested distallisation of lower 6's to create
spaces and Dr. Paul M. Thomas suggested implants for 7's replacement.

However, would there anymore alternative available when the patient is not
able to afford the prosthesis (implant and prostho fee) and furthermore,
how successful has anyone distallised lower 6's to create 7-9mm of space for
alignment.

I dont mean to offer orthodontic as charity work as it is really hard work
to make patient's mouth perfect. But given the situation to present itself
in one of close friends or relatives, it would be tempting to attempt to
"utilise" unerupted teeth for replacement of bad teeth.

It may be difficult to upright the tooth but how much different it would be
than applying tipping type of tooth movement?

I hope anyone can enlighten me further on this matter and I do really
appreciate all the previous alternatives offered.

Sincerely yours;

Tengku

We have bought the software a few months ago, after I had seen it at Chicago AAO meeting. We are now quite happy with it. At the beginning we had just a few problems with our flatbed scanner that did not seem to work properly with the software. The tech support from Italy solved our problem.
It is not very difficult to learn how to use the software if you are familiar with the occlusogram, as described by Marcotte, even if I have to say that the on-line manual is not very well written.
3DO combines the lateral ceph with the occlusal images of the dental arches. The basic concept is that you move the front teeth to the desired position on the X-ray, and then you see on the occlusal view of the dental arches the movements that all the teeth should do to reach their final desired position.
We are now using 3dO to do the treatment planning of our most difficult cases.
There is a paper published on the AJO about this software.

Hi All:

I was wondering if anyone was familiar with a software program that
could be used to plot the location of patient addresses on a map so that
I could visualize possible clusters. I am in the process of moving to a
larger office and thought it would be wise to first get a better feel
for exactly how my patient base is distributed before selecting a new
location.

If such a program exists, I am wondering how difficult it would be for
that program to then use my practice management software, IMS, as the
source for the addresses. If anyone has any knowledge of such a program
or can point me in the right direction it would be greatly appreciated.

Thanks in advance,

Mark

Thank you for your information and the example you gave about a transfer patient.
I think that I too would do the same, tell the patient to come later,
What got me , I think is because I didn"t have a really good class III when I received the patient. No family history too.
Anyway, I can tell him how it would be good for him to wear the chin cup now and see what happens. It would be a good experience.
In such cases, not really a strong class III, the opinions between my friends get divided. Some think better to let even the suspected cases go to older age, and then treat ,others like to interfere, to make the client not look so bad, in such an important age , and not hold possible maxila growth. I fit in the second group.
although class III surgery is the one I like most, find it with a great success rate, compared to others, like open bite. Its a pity that patients here are so difficult to convince.
I have one friend that has an excellent orthognathic rate in her office, but her husband is the surgeon.

For those of you who are not subscribers to Compuserve, you may be interested
in the following report (which is a "headline") from the front page of
Compuserve. I must admit that there are days when I feel like I'm driving a
buckboard. What do you think?
Look, Ma! Straight Teeth, No Braces
Orthodontia is a rite of passage for many youngsters. Wires and silver and
rubber bands and expanders and a few teasing nicknames are all part of the
deal. That could all change. A Silicon Valley startup called Align Technology
Inc. has created a 3D computing imaging system that straightens teeth without
metal braces. "Orthodontics has been in the horse-and-buggy age for a long
time now. We are this industry's automobile," said Kelsey Wirth, Align's
31-year-old president and daughter of former Colorado Senator Tim Wirth. The
patented system, which has been named "Invisalign," maps out a treatment plan
using 3D computer images. Then the computer software allows Align's
technicians to create a series of clear, removable retainer-like
molds--called "aligners"--that move teeth with few hassles, little pain, and
no obtrusive wires or brackets. In most cases, a patient would wear 20
different removable "aligners" for two- to three-week periods. Orthodontists
have their reservations. "It's not a cure-all. It's going to be more of a
niche product," predicted California orthodontist Dr. Michel Van Bergen.
"There is also potential for abuse here. There could be more dentists that
may try to use (Invisalign) just to make patients look good, but they might
not get the bite quite right." No matter. Align Technology is planning an
initial public offering that could be filed as early as this week. --Cathryn

In a message dated 9/20/00
Zia Chishti
Chairman and Chief Executive Officer
Align Technology, Inc.
questions the paranoia of orthodontists regarding Invisalign

I'm not paranoid about the technology, in fact I think it is a marvelous
complement to existing methodology and with time and experience will prove to
be more useful than is now recognized. My clinical experience to date is
positive, but 90% of eligible patients have declined due to cost. Obviously,
I need coaching on marketing or fee cutting.

Perhaps Zia Chisti would be comfortable explaining why we have listed, in
Portland Oregon, a general dentist, Dr Roger Amiton, as an Align certified
orthodontist? Look it up for yourselves on the Align website.

I still really dislike merchants getting into a study club and calling a
doctor's post "Inflamatory."

I think it is "Inflamatory" to have a merchant get in between a conversation
of orthodontists.

Don't you think that if we wanted the opinion of a particular merchant we
would know where to go???

Of course I will not give out my opinion on Invisalign in this forum. But if
anyone wants to approach me directly I would share my opinions.

I feel it is a lose to our study club to allow this to happen and miss out on
real opinions about what happens in the clinic.

Again I exhort our organizers to allow merchants to view, but do not
participate in our discussions.

--------------------------------------------------------------

Dear Fellow ESCO Members,

This note is in response to recent postings by Dr. John Schuler and Dr.
Vaughn Johnson regarding Invisalign.

I am the Chairman and CEO of Align Technology, the manufacturer of the
Invisalign System.

Dr. Schuler's posting is inflamatory. Although his posting is in the form
of a question, it implies Dr. Schuler's belief that Align Technology will
not survive greater than two years and, as a consequence, the orthodontic
profession will be left without Align Technology's support.

Perhaps Dr. Schuler is not aware of our organization. Briefly:

1. We employ over 1100 people worldwide, more than the top three
orthodontic manufacturers combined.
2. We have over $150 million in capital with over $10 billion in additional
financial resources available to us through our financial partners.
3. We have trained over 4300 orthodontists in the U.S. on the use of the
Invisalign System.
4. Over 2000 orthodontists are already Align Technology customers.
5. We are the fastest-growing orthodontic company in history.
6. The vast majority of patients and orthodontists that have used the
Invisalign System are highly enthusiastic about their experience.

Dr. Johnson's posting regarding our recent price increase could be
interpreted as humorous, but, in the interest of clarity, I would like to
state that our price changes were not in response to any balance sheet
constraint. In fact, we have no outstanding material financial debts at
all. Instead, our price changes were consistent with the costs of running
our business and the current level of demand we are facing from our
customers.

At Align we are doing our best to improve the selection of treatments that
orthodontists can offer their patients. We urge our partners in the
orthodontic community to support our efforts to help them. Inflamatory,
reactionary or cynical postings do a disservice to the broader orthodontic
community and are disheartening to the 1100 employees of Align. If there
are legitimate questions about Align Technology or the Invisalign System, we
would be delighted to speak to them directly.

Sincerely

Zia Chishti

Just curious about the previous posting about the trendline on Infocure -
this prompted me to look up their "chart". It appears that they own a
number of Practice management systems - ie, they're out there buying out all
the competition. Is this why there is very little good ortho management
software around - no one seems to be completely satisfied.

Dear Sir,
             I did my thesis on occlusograms in 1984 for masters degree
(BOMBAY UNIV.) by taking 1:1 x-rays of the orianted models with central
groove, instead of the 1:1 photographs as suggested by Dr. Burstone ,
Dr. Marrcotte & Dr Larry White , as it shows the apical base as well as
the teeth .You can have guideline as where to position the teeth over
apical base.I compared the norms given by larry white for occlusograms
with my sample size of 30 Class I crowding cases , & did comparritive
study with Bezley's & Nance's method to find out the discrepancy within
the arch & statistcally proved that occlusogram method is superior over
these other methods .It was in 1982-1984 period that time I read one
article for 3D occlusogram with Holography by Japenise orthodontist .
But over all occlusograms are still to make a mark in every
orthodontist's mind.
Can anybody give me the lists of articles published after 1984 in our
ortho journals?

Thanks ,
Dr.Uday M. Wadadekar ( druday@vsnl.com )

Dear Sir,
             I did my thesis on occlusograms in 1984 for masters degree (BOMBAY UNIV.) by taking 1:1 x-rays of the orianted models with central groove, instead of the 1:1 photographs as suggested by Dr. Burstone , Dr. Marrcotte & Dr Larry White , as it shows the apical base as well as the teeth .You can have guideline as where to position the teeth over apical base.I compared the norms given by larry white for occlusograms with my sample size of 30 Class I crowding cases , & did comparritive study with Bezley's & Nance's method to find out the discrepancy within the arch & statistcally proved that occlusogram method is superior over these other methods .It was in 1982-1984 period that time I read one article for 3D occlusogram with Holography by Japenise orthodontist . But over all occlusograms are still to make a mark in every orthodontist's mind.
Can anybody give me the lists of articles published after 1984 in our ortho journals?

Thanks ,
Dr.Uday M. Wadadekar ( druday@vsnl.com )

Subject: Automated Cephalometric Landmark recognition

From: "jm" <braces@bigpond.net.au>
To: <orthod-l@usc.edu>
I am about to embark on a software project involving "Automated
Cephalometric Landmark recognition".

I am curious as to whether there would be a demand for such software.  I
have been following the research and papers on this subject for about 10
years and it appears that like voice recognition it may be more trouble than
it is worth.  For example with voice recognition the "teaching" curve is so
steep that it is still easier to use a Dictaphone and a typist with some
good word processing/correspondence software linked to a practice/patient
management package.  Not to mention the plethora of "manual" transcription
services that are now available on the net.

Given that you can now digitise and analyse a ceph within 5 minutes and
often a procedure that can be delegated to auxiliaries - would I be right in
assuming that Automated Landmark recognition would only be useful in a
research environ involving large samples?

Is anyone else working on such a project?

I still really dislike merchants getting into a study club and calling a

I think it is "Inflammatory" to have a merchant get in between a

Don't you think that if we wanted the opinion of a particular merchant we
would know where to go???

Of course I will not give out my opinion on Invisalign in this forum. But if
anyone wants to approach me directly I would share my opinions.

I feel it is a lose to our study club to allow this to happen and miss out
on
real opinions about what happens in the clinic.

Again I exhort our organizers to allow merchants to view, but do not
participate in our discussions.

Dear Fellow ESCO Members,

This note is in response to recent postings by Dr. John Schuler and Dr.
Vaughn Johnson regarding Invisalign.

I am the Chairman and CEO of Align Technology, the manufacturer of the
Invisalign System.

Dr. Schuler's posting is inflamatory. Although his posting is in the form
of a question, it implies Dr. Schuler's belief that Align Technology will
not survive greater than two years and, as a consequence, the orthodontic
profession will be left without Align Technology's support.

Dr. Johnson's posting regarding our recent price increase could be
interpreted as humorous, but, in the interest of clarity, I would like to
state that our price changes were not in response to any balance sheet
constraint. In fact, we have no outstanding material financial debts at
all. Instead, our price changes were consistent with the costs of running
our business and the current level of demand we are facing from our
customers.
(edited for brevity)
At Align we are doing our best to improve the selection of treatments that
orthodontists can offer their patients. We urge our partners in the
orthodontic community to support our efforts to help them. Inflamatory,
reactionary or cynical postings do a disservice to the broader orthodontic
community and are disheartening to the 1100 employees of Align. If there
are legitimate questions about Align Technology or the Invisalign System, we
would be delighted to speak to them directly.

Sincerely

Zia Chishti
Chairman and Chief Executive Officer
Align Technology, Inc.
Sunnyvale, California
   >>
I use Invisalign where appropriate, and feel there is a limited place for
this technology, which is severely limited by the fact there is no way the
occlusion can be fitted or aligned using interarch elastics. We do not know
how many "treatments" will need to be retreated using conventional braces to
correct the occlusion.
      This forum is now "chilled" by the fact that doctors can't freely
express their "professional" opinion on the efficacy of a medical device
without their opinion being attacked on nonmedical grounds by the
manufacturer. Rather than attacking the opinion, the manufacturer needs to
address the concerns and comments of their customers (orthodontists)

They have two products. Streets and Triplanner, I think. But they are
manually operated programs so someone would have to input all the stuff
manually. Not going to interface with your management database.

Dear Dr. Kahn,

The below copied material is from DR. Z's Web page. In it he states that the
purpose of the ESCO is " a free service, operated on the Internet by Dr.
Joseph Zernik from the University of Southern California. It is intended for
free exchange of information and opinions by members of our profession."

Quite frankly I'm not really sure what he means by "members of our
profession." Is that an expansive term meaning everyone involved with
orthodontics should have a voice? Or is Dr. Z a strict constructionist and
feels only those who are board eligible should have a voice?

As I read the rest of his Web page, I noticed that he was kind enough to
include a posting by the luminary from Portland, OR, Dr. Carter. You'll
notice that Dr. Carter has taken an expansionist viewpoint and feels this
forum is for those who are an "orthodontist, pediatric dentist, a lay person
involved with dental products, dental practice management, etc.?"

He goes on to say that this forum should be expansive in nature because "this
helps all of us understand your position."

One has to assume that Dr Z shares this opinion since he has included this
material on his Web page. One might think of this material as a charter of
the ESCO.

If that is so, can we put it to rest as far as who participates? I for one
think the more the merrier. Of course, I do have my doubts about pediatric
dentists, but being younger and less wise than Dick Carter, I will acceed to
his wisdom in this matter.

Those are my two cents for what it is worth!!!

is:
1. In the SUBJECT section at the top of most E mail programs; Instead of
using the default subject, i.e. root paralleling for implants, insert a
succinct keyword or keywords of YOUR message. My example is the subject of
this message as written at the top of the window you are currently viewing
2. After a brief synopsis of the message you are responding to, state your
message. Please do not copy the entire previous message. We can all find it
in our "old mail" on our discs. If you cannot do this, read the instructions
on your E-mail program. Most have a history section.
3. Sign your actual name, not your anonymous screen name.
4. Your city and country, please. Anyone who can access the internet and
correspond in English should be proud of where they come from - even
Californians.
5. Your professional interest in the debate at hand. Are you an orthodontist,
pediatric dentist, a lay person involved with dental products, dental
practice management, etc.? This helps all of us understand your position. It
also allows AAO members to access a database which tells us who you are.
6. Please don't repeat your E mail address - it is automatically included in
everyone's E mail postings.
Thank you for your support. I love this game! I especially enjoy the
international comments and do not expect perfect English. Especially from
young Americans. Just do it! Ciao. Domo arrigato.

Dear Colleagues:

Charlie Ruff has raised questions regarding the posting of messages from
non-orthodontists on ESCO. In general - our policy is as stated - to limit
this forum to discussion among members of our professional community. In
accordance with this policy, we block numerous messages that come from
patients requesting online consultation, or from advertisers, etc.
However, when an individual, a corporation, or a product is discussed, and
the relevant parties feel that they have not been fairly represented in the
discussion, at times we allowed them to respond.

We are glad to be of service to the orthodontic community, and we are
grateful to all of you who post material on ESCO. These contributions are
what keeps this forum interesting and informative. In particular, we are
interested in clinical material, including clinical photographs or
radiographs. Such images ideally should be displayed on your web page, and
the URL included in the email message.

Cheers,

Joe Zernik

Thanks for the info. I ordered a product from Microsoft called
MapPoint. It is supposed to digest data from one program and will map
by address. I called my practice management provider, IMS, and was
advised that this would not be a problem. They will take my data, save
it to another file to avoid corruption and MapPoint will extract data
from this file to plot patient addresses. Sounds pretty easy but I will
know for sure once I have attempted the task.

Dear Orthodontic Study ;

    I have been watching the developments of invisalign in the last view
months. And I have these observations.

1.) I feel that it has some potential in the treatment of selected
cases. Which cases one should select is the big question at this point
in time. I feel it has at best a "niche" potential in treating
orthodontic cases.

2.) I feel that there seems to be an aggressive attitude on the part of
Invisalign in promoting their product. I saw a commercial the other
night on TV that presented a somewhat negative image of traditional
fixed appliances. I feel that venture capitalists should learn to
respect the profession that they are allegedly hoping to help.

3.) Venture capitalists are essentially people who fund projects that
they hope will be financial successes. Therefore, I am concerned that
some venture capitalists will not use "good" judgment when they promote
their products. I read an article in USA Today that portrayed
orthodontics as being in the
"horse and buggy" mode. I do not feel that I am in the horse and buggy
mode.

4.) In the present climate of the health care arena, I feel that the
doctor is the only person who will protect the patients interests. I am
not sure if Venture Capitalists have the same commitment to the patient
that the doctor has. Especially after reading some on the posts on the
Electronic Orthodontic Study Club.

I show no ill will towards anyone here. I mean everything in the nicest
way possible. But I suspect that there is the potential for divergent
motivations when new technologies are promoted by Venture Capitalists.

Dear Zia Chisti,

The nature of orthodontics has been and will continue to be based on long
term relationships. The entire industry is essentially an informal
fraternal organization. This includes clinicians, staff, lab people, and
retailers. The essence of our professional relationships with patients is
long term. Naturally, there are exceptions but, in the main, most of us like
it this way.

I assume this is one of the reasons you hired a force of sales reps that had
previous ortho experience. They knew the clinicians and already had
relationships extablished.

Having said that, I am not privy to your business plan and whether these
traditional relationships are important to you. One of the criticisms of
American business is that the only thing that matters is the botton line for
this quarter. Perhaps a more long term focus would be in everyone's best
interest unless of course your business plan calls for your relationship with
us to be nothing more than a megabeta test before taking your technology
elsewhere.

Dear members,

What does everyone think of the new Invisalign commercials? Do you
think they present fixed appliances in a positive image or in direct
competition to traditional appliances? Do you think they are destroying

what we have worked for years to create? Do you think the AAO
convention is a suitable place for their product to be displayed? I
assume attendance at our convention is by invitation of the membership.

Just a thought or two.

John L. Schuler D.D.S., M.S.
Peoria, IL

I live in upstate New York and the adds started appearing last week, I
have been questioned about Invisalign by several patients. I tell my
patients the following when asked about the Invisalign system

    1) The technique is limited as to the type of case that can be
treated
    2) Since it is new I have no way of knowing what the long term
stability of the cases treated with Invisalign will be. However
            I would like to see cases 2 to 3 years post treatment to
determine stability, before incorporating it into my practice.
    3) The cost is high is comparison to traditional orthodontic therapy

I have not had anyone insist on being treated with Invisalign, but I
have no qualms about sending them to someone else if they do

What is interesting is that many of the people who ask about the
Invisalign system are skeptical about it and feel it will not work.

I had the opportunity to see one add last evening, I was curious where
they found someone with braces that large? and he could have brushed
before his close-up? Since I have been in practice for 21 years I've
seen enough new and improved things come and go, I have no problem
incorporating new techniques in my office but I need to see long term
results before I make the leap. I also remember what one of my
professors told me about new techniques. Always ask to see the failures,
and if they tell you there are none, then stay away because nothing
works 100% of the time.

I feel that we should just sit back see what happens, we've had this
occur before and orthodontics has managed to survive. However, I do take
offense at the statement that orthodontics is in the horse and buggy
stage, not a good way to win friends and influence people.

Dear fellow ESCOlytes;
    My website (drted.com) usually experiences about 40M hits which
translates to about 2000 unique visitors. This month as a result of
Invisalign's ad campaign my site experienced just under 100M. I'm inpressed.
It tells me folk are very, very intersted in this technique. It also tell me
that AT is our ally, not teh enemy. As a result this week I have scheduled
16+ consultations 7 of whom have resulted from this ad campaign. I am a
certified provider of Invisalign and have 7 patients under way. I offer it to
every patient who fits their formuala: "mild-moderate" cases of crowding and
spacing. Where I am uncertain I send the company the PVS's and let them
advise me. My fee for Invisalign upper and lower is presently $6585. $7985
for lingual upper and clear lower. I have not encountered any problems in
mixing techniques where it is appropriate. In fact, patients seem quite
pleased that in some cases they can mix and match lingual with clear or
Invisalign. Choose your candidates for Invisalign with care and advise your
patients at the start of the possible need to default to lingual or clear in
the event of patient burnout or the correction not materializing. What is
important to remember is that many patients are not good candidates:
children, extraction cases, open bites, deep vertical overbites, etc and
therefore you have the legitimate option of introducing them to other
alternatives that they could well choose: lingual and clear-transparent for
instance. What appears to be good for the public is good for all of us as
well. As long as I can default to alternative treatment options without any
financial loss I owe it to myself, my patients and my profession to be on the
cutting edge of this latest, and I believe here-to-stay, technique. When AT
goes public It is a buy for me.
Cordially, Ted P.s. Some downers: 1. A two year case will cost us about
$2300 2. Initial delivery time is 6-8 weeks. 3. Storage space: Align's
packaging is presently way too cumbersome. Some uppers: 1. Chair time is
lessened. 2. This new generation of techies enjoys going to the Invisalign
site and viewing the animated treatment plan simultaneous with their wearing
the aligners 3. No dietary restrictions, no broken brackets, no lost
chair-time due to rebonding.   What we need now is to hear the "horror
stories" (if there are any) from the guys in the trenches who are using the
Invisalign technique now. Recordially, Ted ;-)

Dear Fellow ESCO Members,

I am the Chairman and CEO of Align Technology, Inc., manufacturers of the
Invisalign System.

In ESCO Digest #725 there were six postings regarding Invisalign.

Dr Bedi from Delhi, India asked for websites that would have information
regarding Invisalign. In addition to our own website (www.invisalign.com)
there are several websites that have information on us. A short list
includes:

http://www.oc-j.com/products/Invisalign.htm
http://www.channel2000.com/news/health/stories/news-health-990907-141252.htm
l
http://www.dentistsonmain.com/web_pages/cosmetic_3.htm
http://ebody.com/orthodontics/articles/200005/article1076.html
http://www.wfla.com/health/457.htm

A Google or other search engine search on "Invisalign" will also show up
many more sites with information on the Invisalign System.

Dr Kahn suggests that merchants not be allowed to post on the ESCO site. I
acknowledge Dr. Kahn's comments, but offer that greater dialog will only
contribute to greater ultimate knowledge and understanding. Trying to choke
off information will do everyone a disservice.

The ESCO recommendations for posting guide us to establishing our identity
and purpose for posting early on in our messages. I try to do so at the
outset. Should anyone choose not to want to read my postings, I submit that
the burden of moving past them is no more than a few seconds of time. By
design, posting to ESCO does not *force* anyone to read a particular
article.

Four of the remaining six postings are from Dr. Schuler. Dr. Schuler's main
points are:

1. I have no right to state my interpretation of his posting.
2. I imply that he is ignorant.
3. An apology to me for hurting my feelings.
4. A request for an apology on my part for hurting his feelings.
5. He has had no patients ask for the Invisalign System.
6. It is not good practice for the CEO of a Company to aggressively respond
to a questioning of the long term viability of such a Company.
7. Invisalign has an inflamatory response in the periodontal membrane of
patients.
8. A questioning of the effectiveness and appropriateness of our
advertising.
9. A questioning of the mechanism of charging patients for Invisalign.

In order:

Dr. Schuler's precise posting which led me to infer a belief on his part
regarding Invisalign was: "How about a general comment on Invisalign. Who
thinks it will be with us 2 years from now and who will be left holding the
bag?" My opinion is that were Dr. Schuler less skeptical in his standpoint,
he might have phrased his question more along the lines of "Do any of my
colleagues know the business position of Align Technology? I am concerned
because I would like to be certain that the Company will be capable of
supporting the profession over the long term." If my interpretation of Dr.
Schuler's posting was incorrect, than I apologize. If not, then my comments
stand.

Were Dr. Schuler aware of our business position, I do not believe he would
have asked his question both in the form and substance that he did. If this
is so, Dr. Schuler was indeed uninformed about us.

If Dr. Schuler is genuinely apologizing for hurting the feelings of the 1100
employees of Align Technology, I accept the apology.

If I have hurt Dr. Schuler's feelings, I apologize.

Align Technology is doing its best to drive consumer demand for the
Invisalign System. We drive referrals primarily to "Tier I" and "Tier II"
doctors who have vocally advocated their desire to treat patients with
Invisalign System and have fully positioned their practices to take
advantage of the referrals we send their way. Dr. Schuler is a "Tier III"
doctor which, in our framework, refers to doctors that have been trained and
have purchased the PVS system but who have not strongly voiced their desire
to participate in our referral program or have an area of practice
development that indicates a lack of preparedness in being able to handle
Align Technology driven referrals. This perhaps explains some of why Dr.
Schuler has not received patient inquiries. Should Dr. Schuler -- or any of
our orthodontist partners -- like us to do so, we would be happy to work
with them to develop their practices to Tier I or Tier II status.

I disagree with Dr. Schuler's view that a CEO of Company should not respond
aggressively to a statement questioning the Company's viability. The two
examples Dr. Schuler chooses to make his case are of Jeff Bezos at
Amazon.com and Michael Eisner at Disney. Jeff Bezos is actually a peer of
mine: Kleiner Perkins Caufield & Byers was the first venture capital
investor in both Amazon.com as well as Align Technology. Jeff Bezos in fact
responds very aggressively to statements regarding the long-term viability
of Amazon.com. For recent reference, please refer to an interview of him in
the Red Herring October 2000 issue. Here is the online link:
(http://www.redherring.com/mag/issue83/mag-bezos-83.html). The Eisner /
Euro Disney example is inappropriate: even if EuroDisney failed, the long
term health of the Walt Disney Company (which is a minority shareholder in
EuroDisney) would never come into question. Even so, Mike Eisner responds
very aggressively to negative comments regarding the effects of the Euro
Disney debacle on the Walt Disney Company. For reference, please read
Fortune's April 1995 article on Disney and Mike Eisner. Here is the online
link
(http://library.northernlight.com/SG19990714090001744.html?cb=13&sc=0#doc).
You might have to read little deep into this article before you hear
Eisner's most aggressive responses to what was an uncontestible failure.
Quite the reverse of Dr. Schuler's assertion, it is the duty of a CEO to
speak to the integrity of his Company particularly when challenged in a
public forum.

A mild inflamatory response in the periodontal ligament and supporting
tissue as the result of orthodontic treatment is perfectly normal and
consistent with all orthodontic treatment. Excessive force, however, can
result in an uncontrolled such inflamatory response which can slow or even
halt orthodontic movement and potentially increase root resorption (I am not
aware of any published studies on this specific concern, although this is a
common belief in the academic community). By design, the Invisalign System
limits the amount of force applied to a particular tooth and, accordingly,
reduces the potential for both inflamation and root resorption. If Dr.
Schuler has experienced an aggressive inflamatory response with the use of
the Invisalign System, this would be the first such recorded incident in
over 6,000 cases and we would be priviliged if Dr. Schuler would allow us to
investigate.

By all accounts, our advertising has been extraordinarily effective. In the
ten days since we initiated advertising, we have generated over 80,000
referrals to our Tier I and Tier II orthodontists. If Dr. Schuler is
sensitive to the contrast we draw between treatment with traditional metal
appliances and Invisalign aligners, we ask why?

While at Align Technology we have no control over what doctors choose to
charge their patients, we do have a few suggestions. To price the
Invisalign System treatment to patients, we submit that the amount of
physical labor an orthodontist need put in to treating a given case goes
down dramatically with Invisalign. Many cases can be treated with as little
as an hour or two of effort. In using the Invisalign System, orthodontists
need no longer purchase the metal appliances, another source of savings.
Also, the Invisalign System allows orthodontists to attract new patients
that would otherwise not have sought treatment. With these factors in mind,
many orthodontists are charging fees that are equivalent to what they charge
with metal braces. The majority of orthodontists we survey are charging a
small premium for the treatment, typically in line with what they would
charge for ceramic braces or other such more aesthetic alternatives. Our
sales representatives in the field are happy to help develop pricing
strategies with individual doctors who might make such a request.

cannot believe the calls i have been getting on this product this week.
evidntly, there is a powerful commercial on tv. even though i took the
course and then accidently heard boyd speak on it two weeks later in
more dramatic detail, i have refused every one. total costs for me and
the patient, especially after the new price list that came out a couple
of weeks ago, plus the distinct uncertainty of a precise end result have
shaped my thinking. usually i am a leader in utilizing innovations, but
this time i'll it out and observe for some time. (probably retire by
then). the only thing i think i would use it for is spacing upper
anteriors for veneers. limitations, limitations.

Dr. Schuler's comments are what we are hoping to hear on this forum. The
response from the young lady could have respectfully been submitted
directly. There is obviously a failure on the part of Invisalign, and
reputable companies typically strive to resolve these issues. The problem
might well be due to a muturity issue and lack of classical business skills.

Members,

I just finished aligners on one patient that had 5mm of crowding. The aligners only corrected it approx. 80%. So far I am not seeing total correction with the cases.

Dear members,

I hate to see 25% increase in setup fee and aligner fee. Recently my referral dentist has been coming up to me to inform me that it is only a matter of time before general practitioners will be doing Invisalign. Even the GP knows now.

Dear Members,

We now know that the price increase is a result of the demand( Basic econnomics). So if we want to decrease the price, we need to decrease the demand as Zia Chishti has informed us. Thanks for the info.

Respectfully submitted

Dear Fellow ESCO Members,

This note is in response to recent postings by Dr. John Schuler and Dr. Vaughn Johnson regarding Invisalign.

I am the Chairman and CEO of Align Technology, the manufacturer of the Invisalign System.

Dr. Schuler's posting is inflamatory. Although his posting is in the form of a question, it implies Dr. Schuler's belief that Align Technology will not survive greater than two years and, as a consequence, the orthodontic profession will be left without Align Technology's support.

Perhaps Dr. Schuler is not aware of our organization. Briefly:

1. We employ over 1100 people worldwide, more than the top three orthodontic manufacturers combined.
2. We have over $150 million in capital with over $10 billion in additional financial resources available to us through our financial partners.
3. We have trained over 4300 orthodontists in the U.S. on the use of the Invisalign System.
4. Over 2000 orthodontists are already Align Technology customers.
5. We are the fastest-growing orthodontic company in history.
6. The vast majority of patients and orthodontists that have used the Invisalign System are highly enthusiastic about their experience.

Dr. Johnson's posting regarding our recent price increase could be interpreted as humorous, but, in the interest of clarity, I would like to state that our price changes were not in response to any balance sheet constraint. In fact, we have no outstanding material financial debts at all. Instead, our price changes were consistent with the costs of running our business and the current level of demand we are facing from our customers.

At Align we are doing our best to improve the selection of treatments that orthodontists can offer their patients. We urge our partners in the orthodontic community to support our efforts to help them. Inflamatory, reactionary or cynical postings do a disservice to the broader orthodontic community and are disheartening to the 1100 employees of Align. If there are legitimate questions about Align Technology or the Invisalign System, we would be delighted to speak to them directly.

Sincerely

Zia Chishti
Chairman and Chief Executive Officer
Align Technology, Inc.
Sunnyvale, California

Dear Members,
One of our practice's patients has been reported missing from our
practice in Kokomo, Indiana. He is a 16 year old male named Mike
Burleson. He has been missing since September 13 when he came home from
school, collected several personal belongings and left his house. He is
believed to be a runaway. He is approximately 5'4" tall and 115
pounds. He may be driving a 1989 black Buick LeSabre with a Texas
license plate. He has had braces on for several months and I am posting
this message in case he may show up in an office with an emergency
problem claiming to be on vacation, etc. He may wear a yellow baseball
cap backwards (he often did in our office) I will attach his photo to
this message, but in case it doesn't get forwarded please view it at
http://www.flyingmonk.simplenet.com/mburleson.html
Please contact the other specialists in your area with this information
as I know not everyone subscribes to ESCO. If you have any information,
please contact Det. Steve Rogers at the Howard County Sheriff Department
at (765) 456-2031 or Det. Gary Stout at the Tipton County Police
Department at (765) 675-2152.

Thanks,

-------------------------------

So what's new? If a general dentist pays more attention to malalignment, we will get more referrals. If he stumbles in his orthodontic efforts, we will get more referrals. If he is just getting started in orthodontic treatment, he will stumble. If a the dentist has paid Invisalign a fee, perhaps that opens Invisalign to liability, especially if Invisalign has participated in the diagnosis and treatment plan which seems to me inherent in the lab services.

Anything that generates interest in straight teeth and eventual recognition that we, orthodontists, have the special knowledge required to get the job done properly is excellent. So, Invisalign pump your services, dentists perform orthodontic treatment, lawyers sue to your hearts content. Let capitalism thrive as will we.

Dear Dr. Chishti,

I'm sorry, I did not know you were an orthodontist. Where did you do your
training? Possibly we have mutual friends. I did however, appreciate the
orthodontic lecture. I'll pass this ground breaking information on to my
residents. It also helps if you know how to spell inflammatory.

John L. Schuler D.D.S., M.S.
Peoria, Il
Associate Professor of Orthodontics
University of Louisville

<<A mild inflamatory response in the periodontal ligament and supporting
tissue as the result of orthodontic treatment is perfectly normal and
consistent with all orthodontic treatment. Excessive force, however, can
result in an uncontrolled such inflamatory response which can slow or even
halt orthodontic movement and potentially increase root resorption (I am not
aware of any published studies on this specific concern, although this is a
common belief in the academic community). By design, the Invisalign System
limits the amount of force applied to a particular tooth and, accordingly,
reduces the potential for both inflamation and root resorption. If Dr.
Schuler has experienced an aggressive inflamatory response with the use of
the Invisalign System, this would be the first such recorded incident in
over 6,000 cases and we would be priviliged if Dr. Schuler would allow us to
investigate.>>

P.S. Even though you are an orthodontic colleague, could you please not give
out what I assumed was privileged information regarding my practice over the
internet?

<<Align Technology is doing its best to drive consumer demand for the
Invisalign System. We drive referrals primarily to "Tier I" and "Tier II"
doctors who have vocally advocated their desire to treat patients with
Invisalign System and have fully positioned their practices to take
advantage of the referrals we send their way. Dr. Schuler is a "Tier III"
doctor which, in our framework, refers to doctors that have been trained and
have purchased the PVS system but who have not strongly voiced their desire
to participate in our referral program or have an area of practice
development that indicates a lack of preparedness in being able to handle
Align Technology driven referrals. This perhaps explains some of why Dr.
Schuler has not received patient inquiries. Should Dr. Schuler -- or any of
our orthodontist partners -- like us to do so, we would be happy to work
with them to develop their practices to Tier I or Tier II status.>>

P.S.S To my ESCO friends and true colleagues: Do you appreciate the way
Dr.? Chishti has responded to my postings?

To the chairman and CEO and other interested parties,

I appreciate hearing your perspective and taking time to respond to this
audience. Understandably, the corporatization of health care has resulted
in some skepticsm among those of us familiar with the cottage industry
approach. The bottomline often seems to be the primary concern. eg.
Infocure, which has purchased management software companies and then
discontinued support in an effort to bolster the bottomline...leaving the
customer "high and dry". A look at their stock trend over the last 10
months (37.4 to 3.5) is certainly of concern for someone depending on them.
http://finance.yahoo.com/q?s=incx&d=b

The skeptic wonders how ATI would respond in a similar circumstance.

You mention I, II and III tier doctors, but when this question was addressed
at the certification workshop in Reno last Sunday, your staff was unable to
provide any firm details regarding how one is assigned to a tier. It's
difficult to achieve a goal if the goal is unknown or at best, a moving
target.

I will give credit for a staff person stating non-orthodontists are not
being certified. In fact, a non-orthodontist in the audience was miffed
that he had attended and could not be certified. Will ATI continue this
policy or will that change depending on the "bottomline"? A skeptic would
suspect that you are being "politically correct" for the moment, but how
long will that last?

I personally am willing to take a cautiously optimistic view until proven
otherwise. The seminar stresses limited application and I appreciate your
cautious approach in that regard. Worst case is ATI creates some consumer
interest and awareness which will result in some patients coming in who
might not otherwise seek consultation.

Good information, Roy....that was my impression looking at the treated cases at the seminar. Did you use any of the "blips" of composite they are now suggesting to get a better "grip" on selected teeth?

I just finished aligners on one patient that had 5mm of crowding. The aligners only corrected it approx. 80%. So far I am not seeing total correction with the cases.

Dear member;

I (not trained at all in invisalign) was just wondering, after viewing the
website of invisalign (http://www.invisalign.com) on the past cases report,
that it may be just cheaper for the patients with most of the type of
malocclusions potrayed to be treated with clear spring positioners or
removable appliances (although you may issue a few of such appliances). I
wonder whether it (invisalign) can be used for a more difficult cases
requiring bicuspids extractions.

I guess the cost would be very intimidating for most people in the world
(probably not in America). Care to share the view on removable appliances
vs invisalign?

This is what disturbs me somewhat. I seriously doubt that ATI will continue their present policy of "orthodontists only". Witness Nobel Biocare who originally would sell only to surgeons certified in university based courses. Now anybody with some $$ can order a handful of implants and start plugging them in. Again....it all comes back to the bottom line...

Dear all,

Need some help with this one.

20 year old patient in braces almost 24 months. Uncovered both max canines
in December 98 and the right one come into place quite nicely. The left one
has not moved. It appears to be neither buccal or lingual but right in the
alveolar bone at the level of the gingiva. The bracket and a very small
amount of tooth is about level with the gingiva halfway between tooth 22
(left lateral) and 24 (left bicuspid).

About a year ago, I realized that tooth 22 was going gingivally and 23 was
not moving. Referred back to the OS and she suggested to the patient that
the tooth was not moving because I did not have adequate space and to have me
make more room so 23 would have room to erupt. Like I'm new at this.

Anyway, unless I wanted to fight it out with the OS and since my mom told me
never to fight with girls, I releveled, made sure there was enough space
(like 13 mm) and watched tooth 22 go gingival again. That's how you waste
this much time.

Now what are my patients options other than an implant? She and her family
want to know what can be done short of an implant or, if nothing can be done,
they are prepared for the implant.

Any thoughts would be appreciated.

Thanks

A nine year old girl was referred to me for my opinion. She has a Class I occlusion. Her 6's and upper and lower incisors are erupted. There is mild crowding of the upper and lower anteriors but this is probably not an extraction case. Her 16, 26, and 36 are severely decayed to the point that over half the crowns are missing (what we would have called bombed out). Who would extract the three molars? Who would opt for RCT, posts and crowns? Why?

I am not sure at what level the marginal gingiva is so cosmetics might be questionable. At least she is old enough that you know there should not be any additional movement of the adjacent teeth via passive eruption. If the tooth is ankylosed it sounds like the perfect implant to me. Even if it is down in the bone, an RCT with post can be fabricated to give the dentist the height to place a crown.

Implant can be done if b. fails. 2. Is direction of eruptive force going thru the center of the tooth in profile (take periapical with force system in place)? If so, you're trying to translate the whole tooth thru bone rather than vertically erupting it. Since ther whole tooth is in bone, the tooth's center of resistance is at the geometric center of the whole tooth (crown + root). Had one of these in my early years of practice. It erupted once I realized what was going on and changed the direction of the applied force (easier to happen then when surgeons ligated around the crown-CEJ: prebonding days of yore).

Cohanim" To: Electronic Study Club for Orthodontics Subject: Re: ankylosed canine Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII I have a 21 year old patient with 23 (left max canine) intruded (and 21 & 22 avulsed) in an accident. 23 became ankylosed (after he was MIA for 3 months) and caused intrusion of 24 and 25. The OS suggested a block osteotomy where you cut a block of bone around 23 and then eruptive forces to move the whole block down. Parents and patient have decided to try it so I used the ankylosed canine as an anchor to bring 24 & 25 back in occlusion and he is scheduled for surgery next week. You might want to ask your OS and see what she thinks about the idea. I would also love to hear Adrian Becker's thoughts on this (if you are reading this!)

If it doesn't move with normal force systems, I think it's unlikely you will bring it into position. I've tried to bring some in that are "stuck", have gone back and re-luxated the tooth and still had marginally success. When I have been able to luxate and move the tooth, they generally have gone "belly up" with external resorption after a period of time. I don't know if it's worth the effort. If there's a bone defect or deficit, I guess you could argue that bringing the tooth closer will help bring bone for placement of an implant. With the current grafting techniques, I'm not sure it's worth the effort, however. I'd start thinking implant. Some restorative people don't like canine implants. I've done more than a dozen without a failure or problem to this point, so I think their concern is unwarranted. -=Paul=- Paul M.

Dr. Vanarsdall at Penn lectures on this and has treated quite a few (I did my Ortho training there). If I recall correctly, the technique goes like this: Re-expose, insure no bone around the crown of the tooth and then gently luxate the tooth, both to get a sense of the ankleosis and free up the tooth if it is indeed only anklosed in a small spot. If it can moved in the socket, close the flap (he recommends an apically positioned flap leaving the crown exposed which I realize is a whole controversial subject in itself, but in a case like this I would think the less impeding the tooth, the better) then immediate force is placed on the tooth and the tooth is retied every day or every other day, the thought being to quickly erupt the tooth passed the anklosed spot and not allow it to re-ankleose. We are talking 1+ mm of movement per day here to insure that it does not get re stuck. If the tooth was not anklosed to begin with, the cause of the ankleosis could have been a nick of the burr during exposure or possibly some etch getting somewhere where it should not be. The point is that the ankleosis may be small and right near the CEJ/alvelor crest area and you may be able to free up the tooth and work past the ankleosis. If you have the space already and the appliances are on, I would think it would be worth the try. You may want to call Dr Vanarsdall or have your surgeon call him for more details. Good luck and let us all know how it works out.

But, try having your OS (the same one or another if she won't co-operate) give the tooth a good "wiggle" in an effort to break any small ankylosed area. This will result in (a) the tooth moving, or (b) further ankylosis and ultimate extraction. It may be more uncomfortable for the patient but IMHO it's worth a try. TGS.

As you well know, dealing with an ankylosed cuspid is problematical at best. Luxating the tooth and then immediately applying light pressure has been known to work, at the risk of devitalization and external resorption. If you go that root(that's a joke!), you could apply pressure with an (.020) auxiliary wire soldered to a heavy base arch between the molar and bicuspid, ligated to the cuspid, and eliminate any reaction on the adjacent teeth. If feasible, a more practical approach might be to root canal the cuspid, build a post to the proper position, and place a crown. I would agree that first creating sufficient space for impacted teeth is of prime importance. Often they will erupt on thir own, more frequently if root development is not complete. It's important to pack the socket so the "tunnel" stays clear of new tissue and bone. My personal feeling is that light traction is important. I recall an article, I believe by Tom Graber, regarding the use of magnets for impacted teeth. What an ideal force; light and constant! On another subject,I favor your tooth identification method (European?) of identifying the quadrant and the tooth, but I'm not certain of its presentation in text. Will someone set the record straight for me: When writing, should the quadrant be identified by a Roman numeral, and should there be a dash between the quadrant and the tooth? I also wonder if there is a mandate for the dental schools to adopt this method. I hope we fare better with this then we did adopting the metric system!

Date: Sat, 7 Oct 2000 23:15:36 -0700 From: Zia Chishti To: "'orthod-l@usc.edu'" Subject: Align Technology response Message-ID: MIME-Version: 1.0 Content-Type: text/plain; charset="iso-8859-1" Dear fellow ESCO members, I am the Chairman and CEO of Align Technology, manufacturers of the Invisalign System. I am writing to respond to various postings over the last few days regarding our system. In ESCO #726, Dr. Lebsack cites a concern regarding the divergence of interests between venture capitalists and patients, and I thank Dr. Lebsack for bringing it forward in the thoughtful manner in which he did. This is a valid concern about business in general, not just venture capital funded businesses. Companies that are in a financially desperate situation are more likely to attempt to bend ethics as a matter of survival -- and some venture funded companies may indeed be in this group -- but it is not just venture-funded companies that find themselves in this situation. Very often, in fact, it is the publically traded companies that are forced by Wall Street to deliver ever higher revenues and profits that find themselves victim of such a financial bind. In this sense, being a privately held company has substantial advantages. The fair way to analyze the likely ethics of a business is to look at its capital resources and financial pressures, the character and credibility of the principle investors and management, and the conduct of the company in the marketplace to date. To the first point we are extraordinarily well funded having raised over $150 million to date (a staggering amount by venture standards) and with access to $10 billion in additional capital through our partners. Our investors are the bluest chip investors who have made their reputations through funding such medical companies as Genentech, GelTex, and Dura Pharmaceuticals, among many others. Other sister companies include AOL, Netscape, Compaq, Amazon.com, Excite, Intuit, and so on. What enables our investors to fund such giant successes is their impeccable reputation for ethical conduct, particularly in the medical marketplace. To the last point, I again thank Dr. Lebsack for pointing out the conservative, manner in which we are introducing the Invisalign System. We intend to be in business for a very long time and we intend to conduct ourselves in a manner consistent with such a long-term view. Dr. Lebsack also cites an article in USA today that portrays orthodontics as being in the "horse and buggy" mode. In fact, many papers carried that phrase as a direct quote from my partner, Ms. Kelsey Wirth who is the President of Align Technology. Let me state categorically that what you read is a misquote. In fact, what Kelsey was referring to was the structural difficulties of introducing a transforming change into a well established marketplace. When the motorcar was first introduced, many horse and buggy drivers criticized it for all manner of perceived imperfections: can't drive it on anything but a paved road, needs expensive gasoline rather than cheap horsefeed, breaks down all the time, requires gears, are ugly, and so on. Kelsey was referring to some of the reactions we were receiving from orthodontists who perceived us in a similar fashion. By no means did she mean to imply anything ill or dismissive regarding the current practice of orthodontics. The comment was simply misquoted out of context and we regret if there was any offense taken. Also in ESCO #726 Dr. Charlie Ruff speaks to the long-term relationship nature of the orthodontic industry, acknowledges our apparent commitment to this industry structure evident in the quality and experience of our sales force, and encourages us to continue on this path. He closes with a concern that we might "take our technology elsewhere", by which I presume he is concerned about potential dissemination to general practice dentists. I thank Dr. Ruff for his acknowledgement of our approach to date, and would like to take this opportunity to speak directly to the issue regarding the potential spread of the technology to GP dentists -- a view that we frequently hear voiced by our orthodontist partners. At Align Technology we have consciously made the choice to limit our sales practices to orthodontists for three basic reasons: (1) The intellectual complexity of treating a case with the Invisalign System is actually higher than in treating a case with traditional appliances. We believe that orthodontists have developed a superior level of insight into the progress and outcomes of treatment to be able to better use our system. (2) As with all medical systems, some degree of failure is inevitable. With the system in the hands of orthodontists, we rest comfortable that an orthodontist will be able to recognize the failure as consistent with all modes of treatment and then simply select an alternative treatment modality to fix the problem. A dentist facing failure would be much more likely to simply blame the product and consequently lower our reputation. (3) Should the orthodontic community on balance take a measured view of our system and try and use it on their patients within our currently restricted case criteria we should more than comfortably make our business projections. As the community's confidence in our system grows, our business should grow comfortably with it. At this time we cannot see any of these three factors changing. The intellectual complexity in using our system remains high, our system continues to be less than perfect, and we are substantially exceeding our business projections. Also in ESCO #726 is a posting by Dr. Ralph Perreca in which he cites a desire for longer-term follow up studies on the effectiveness of the Invisalign System, a skepticism regarding the System by potential patients, a desire for Align Technology to be forthright about our failures, and stated offense at the "horse and buggy" comment that Dr. Lesback also cited. There is no reason to believe that the long-term stability or effects of Invisalign System treatment would be any worse than those achieved with traditional braces. All our cases to date indicate roots in good condition (and in many cases arguably in better condition than with braces). As a removable device, the quality of oral hygeine and periodontal tissue is unambiguously better. Many patients and doctors are naturally somewhat skeptical about the Invisalign System. It is new, offers a remarkable shift from braces, and promises a great deal. Frequently we hear patient comments like "It can't really be invisible" or "They said that ceramic braces were invisible too" or (and this also comes from doctors) "Can it really move teeth?". Improved patient and doctor awareness is simply a matter of time and experience. In Austin and San Diego, for example, where we initially test-marketed our system over a year ago we addressed many of these concerns. Now, the majority of practioners in the Austin and San Diego area that have developed experience with Invisalign System speak confidently and directly to these questions. On the issue of failures, we are the first to admit that the Invisalign System is not perfect. There have been failures in testing and there will be failures in the field. Three points need to be made here. First, a deviation from intended treatment may simply require the retaking and resubmission of impressions to correct -- we are upfront about this in all our training. Second, every medical treatment has some degree of failure, be the modality braces, positioners, or orthognathic surgery; we are no different. That is a core reason why we orient the Invisalign System towards the specialists. Third, the cost of failure is extremely low in orthodontic treatment. It is unheard of that an appropriately monitored Invisalign System case would result in an irremediable situation for a patient. At worst, they will be no worse off than before treatment. I hope I have already adequately spoken to Dr. Perreca's comment regarding our alleged characterization of the traditional practice orthodontics as "horse and buggy" in nature. We regret that we have unintentionally caused Dr. Perreca offense on this point. Dr. Ted Rothstein writes of his experiences with the Invisalign System in ESCO #726. We thank Dr. Rothstein for his thoughful and reflective comments based on personal experience. Such anecdotes of enthusiasm for our efforts make my job worthwhile and are tremendously encouraging to the 1200 staff of Align Technology. It is instructive to note that when Dr. Rothstein calls for more information from his peers about the field clinical success of the Invisalign System he does so in a manner that is heartening and inquisitive rather than combative or cynical. Also in #726 Dr. G. Frankel writes that, despite being certified by Invisalign, he is refusing to treat patients based on the cost of the System and the possibilty of an uncertain final result. We would like to submit that the costs of the Invisalign System are far outweighed by the financial benefits to the orthodontist. Orthodontists are successfully charging their patients a small premium for treatment, generally equivalent to charges for ceramic treatment. If such fees are $5500 for an adult case and the costs of the Invisalign System for such a case are $1500, a doctor makes $4000 on a patient he or she would not otherwise treat and do so in as little as two or three hours of effort. As an example, if Dr. Frankel has received ten calls from prospective patients and had he chosen to treat them he would have earned an additional $40,000 for perhaps twenty to thirty total hours of effort. Many, many doctors are discovering the powerful economic advantages of treating patients with the Invisalign System. Clinical results using the Invisalign System have been outstanding within the case selection criteria that we are advocating. If anything, because of the benefit of our ClinCheck software, final clinical outcomes are much more predictable than with conventional treatment. Should Dr. Frankel or any of our orthodontic partners like us to do so, we would be happy to share results with them through a sales contact and help them learn to use the ClinCheck system with greater efficiency. Dr. Nordstrom writes in ESCO #726 that Align Technology's response to Dr. Schuler could have been handled privately, and that perhaps Align's failure to do so was indicative of a lack of maturity on our part or a paucity of classic business skills. Also Dr. Nordstrom's refers to me as "a young lady". I disagree with Dr. Nordstrom's views. It is the duty of a CEO to defend his company when challenged in public forum. Please see my posting to Dr. Schuler's similar comments published in ESCO #726 for my follow up on these points. Also, I regret to inform Dr. Nordstrom that there is one fewer member of the fairer sex in this world than he has assumed. The last four postings in ESCO #726 are from Dr. Roy King. Dr. King relates a case in which he achieved only 80% correction using Invisalign, comments on his displeasure at our price increase, worries at the transition of the Invisalign System to GP dentists, comments that in order to force us to lower prices orthodontists should treat fewer patients with the Invisalign System, and implies that an apology is due from me to Dr. Schuler. We thank Dr. King for sharing his clinical experience with the Invisalign System. We would suggest, however, that if Dr. King is unsatisfied with the progress of a particular case he retake and resubmit impressions and, more than likely, we will provide him with the aligners necessary for him to complete his case. Should Dr. King need further assistance, his local representative would be delighted to assist him, as would our support staff at Align Technology. On this point, we would like to reiterate that while the Invisalign System is excellent in clinical outcomes within the case selection criteria, it is not perfect. There will be failures and some cases will not complete to full expectations. This is simply the nature of clinical intervention and all experienced orthodontists will have noted this in treatment with traditional appliances. We submit that the Invisalign System should not be held to a higher standard of perfection. For my comments on our price increase, please see my posting in ESCO #723. Dr. King is mistaken in his view that reducing demand for the Invisalign System will reduce prices. In fact, quite the reverse may be true. Should unit demand reduce in the short term, we may be forced to further increase prices to offset our higher per-unit fixed costs. Thankfully, we are in a situation of intense demand for the Invisalign System. On the GP dentist issue, please note my earlier comments in this posting. On the need for an apology to Dr. Schuler, please see ESCO #726. In ESCO #727 Dr. Ron Parsons reacts to Dr King's fear that GP dentists will encroach on the practice of orthodontics with the Invisalign System. Please note my earlier comments in this posting on this point. Dr. Schuler's comments in ESCO #727 are simply not worth responding to. His most potent point is that I misspelled the word "inflammatory" in an earlier posting. In ESCO #727 Dr. Paul Thomas writes questioning the conflicts between business and healthcare in the wake of the accelerating process of health care corporatization. I have written Dr. Thomas back privately on this point and, if Dr. Thomas would like, I would be happy to share those comments on ESCO. I would like to thank Dr. Thomas for his measured views and approach to innovation. In a separate posting in #727 Dr. Thomas reiterates Dr. King's concern about GP dentists. I refer the reader back to my earlier comments in this posting on this issue. Dr. Tengku from Singapore writes asking whether the Invisalign System could not be superceded on a cost basis by cheaper treatments like spring retainers, positioners or other removable devices. Experienced practioners using removable appliances can accomplish extraordinary treatments. Indeed, in some countries removable appliances continue to be the dominant form of orthodontic treatment. However, removable devices are subject to many of the same aesthetic limitations as conventional braces -- and in some instances more so. Most adult patients, for example, could not tolerate walking around with a positioner in their mouths. Our product is designed primarily to appeal to adolescent and adult patients who desire a highly aesthetic treatment solution. For these patients, the benefits of our system are clear. While we are not currently marketing our products outside of the United States and Canada, we will be doing so in the near future. If Dr. Tengku -- or any other international practitioner -- would like, please feel free to correspond with me directly and I will ensure that they will receive first point of reference when we initiate training and sales in their domestic market. In close, this has been a somewhat lengthy posting and I appreciate the reader's interest if they have borne with it to this point. Because of the growing volume of Invisalign based postings, I will in future try to accumulate "themes" and respond to them rather than to individual postings. Best regards to the ESCO membership, Zia Chishti Chairman and CEO Align Technology, Inc. Date: Mon, 09 Oct 2000 01:07:52 -0400 From: Barry Raphael To: orthod-l@usc.edu Subject: Invisalign - just a thought... Message-ID: <39E152A8.A75D20FA@concentric.net> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Does anyone know an older optometrist they can talk to? With all the skirmishing about Invisalign, I wonder if it would be helpful to hear how medical professionals handled it when contact lenses were first introduced. Anybody? Barry Raphael P.S. I've started my 8th case and finished two. So far, I've had only one technical difficulty with the system: rotating a premolar. Zero compliance issues. Only good things to say about the lab. And don't worry about the GP's too much. Some will get it, most will get sick of it. It ain't as easy as it looks. If you think it is difficult making a boderline extraction decision, wait 'til you try to plan a borderline Invisalign case. You can bet they'll be asking for help on half of those cases. Date: Mon, 09 Oct 2000 08:20:27 -0400 From: Rick Walker To: ESCO Subject: more on Align Tech Message-ID: <39E1B80B.901FEF6A@thoughtslinger.com> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit I've been following some of the Align Technologies discussion thread and I thought I'd chip in a few comments. I was in SF earlier this year at the invitation of Bob Boyd (chairman at UOP) and he showed me some of the aligner cases he has underway. He also drove me down to Align Technology's hq in silicon valley for a site visit. I politely declined to sign a non-disclosure agreement during my visit and I explicitly instructed my hosts not to share any confidential information with me, so I feel free to share my impressions. I have no financial interest in the company. My view is that Zia Chishti and Kelsey Wirth are building a company around a promising new technology. Align creates stunningly detailed 3D computer surface reconstructions from models poured from PVS impressions. The surface rendering algorithm looks a lot like the "marching cubes" algorithm which has been heavily used in 3D medical CT and MRI visualization systems. Teeth get moved around on a computer to a final occlusal relationship and aligners are fabricated to intermediate stages. Despite the hot technology - and I tend to get enamoured with tech stuff - I see some room for improvement in the system. The computer projected final occlusal result is a static estimate - last time I played with the software there was no notion of a software articulator to explore lateral and protrusive excursions and build in appropriate cuspid or group guidance. Nor could I identify anticipated occlusal contacts at treatment stages - something that shouldn't be too tough to write using "collision detection" 3D graphics methods. The full sequence of aligners is fabricated from initial models, so I can't see how the system will handle those cases where centric substantially changes after you move a few teeth and de-program the musculature. The good news is that, as with any new techology, there's always the next release. I have great respect for Zia and Kelsey and Alex Benton and the Align Technologies team - they're bright, intensely motivated and well funded. It takes a long time to fully assess whether a new orthodontic treatment modality is successful or not. If weaknesses appear, I expect AT to work hard to improve the system. I think we may be surprised at what is clinically achievable a few years from now. The system may find its place in lots of cases - maybe we'll use conventional fixed appliances to do the heavy lifting in extraction cases and finish with aligners, shortening treatment time in brackets. But Zia - John Schuler's posting in 722 wasn't inflammatory - it's exactly the kind of question I hear orthodontists asking each other all over North America. Everybody who starts an aligner case is, in effect, an investor in your young privately held company and many want to know whether or not you have the cash to get through your growth phase. I took the certification course and it seems to me AT presently recommends fairly narrow case selection criteria. I don't know how well aligners can truly align teeth in tougher cases. We'll have to wait and see if they can achieve root parallelism in extraction cases. I know Bob Boyd is really pushing the limits of the system - I think we need more of this - I encourage Align to set up a low-cost academic program for graduate orthodontic training centers around the world. I know from my early efforts writing Dentofacial Planner that one learns a great deal from independent critical scrutiny - both favourable and unfavourable. We need to see a bunch of articles in peer-reviewed journals written by independent investigators which either validate or invalidate the technique. Ultimately, the quality of clinical results will do the talking, not marketing materials.

Alan,

I personally would not want a lifetime of dealing with molars with RCT,
build-ups and crowns. This is a potential situation for use of implantable
devices to protract the second molars or possibly even conventional implants
to replace the "bombed out" molars. We have used modified titanium screws
in a dog model to successfully move teeth. The screws were placed,
immediated loaded and were intact for 6-8 months of tooth movement. The
bone/titanium interface looked much like an implant/bone interface on the
histology. Based on the results, we are starting some limited clinical
treatment.

Even if you chose to suggest conventional implants, the cost/risk versus
benefit would be favorable. I'm not sure about the fees in Tornoto, but in
our locale, the cost of salvaging the molars you've described would closely
approach that of a restored single tooth fixture. In dental school, we have
been taught to conserve natural teeth whenever possible. I'm not so sure it
isn't time to re-think that paradigm (if you will excuse the use of that
over-used word)

Dear Alan Bobkin hi I have recently tretaed 2 similar cases with decayed
molars. In one of them I decided to extract the molars. Pt was 10 yrs old and
the second mlars moved well in to the extraction sites. I was quite happy with
the occlusion as well . But in the second case where the age of the pt was ok
she was about 11 yrs old the second mlars moved in but were mesially tilted
and didnt correct even after ortho treatment. But I do think that if there are
very badly decayed molars it makes sense to save the patient the headache of
trying to save them if anyway extractions are reqd for ortho treatment.You see
if you have saved them with RCT and post and core and eventually have to
extract the after all the effort coz of failure RCT then its not worth the
effort.                      sorthod-l@usc.edu wrote:

I have spent the last several weeks literally deleting almost every posting
before reading them - the whole discussion of Invisalign has left me
thoroughly bored and ready to quit the ESCO.
At last Charlie Ruff's letter and something of consequence to think about
and to discuss on the net - a breath of fresh air!

Several people made what I would consider really thoughtful and valid
comments - not to mention my heartfelt thanks to Jeff Genecov and Bobby
Cohanim for giving my book a "plug"! Perhaps the gang will permit me to put
in my own pennyworth, based on the suggestions several of you have already
made.

1. Be sure whether or not there is ankylosis! Occasionally, a maxillary
canine tooth
is impacted in the line of the arch and not obviously palatally displaced.
It is not parallel to the adjacent tooth and its crown appears to be jammed
against the distal side of the lateral incisor and, unless traction is
applied in the correct direction, the tooth will not move and the
orthodontists may err in diagnosing ankylosis. This is generally true in
regard to any tooth whose EXACT position and orientation has not been
accurately determined and whose 3-D relationships with adjacent structures
has not been fully pictured in the mind of the operator.

2. Lateral cervical resorption of the root of a partially-erupted or
unerupted tooth is an unusual but reported phenomenon. A case is described
in my
book on pages 172-176 (fig.7.17 a-l). This is not an ankylosis, but rather a
soft-tissue replacing resorption, which neutralizes the eruptive power of
the tooth, presumably due to a loss of integrity of the PDL. These lesions
can usually be seen on a good periapical view. Treatment involves opening a
flap and determining the full extent of the lesion, curettage of the
invasive soft tissue and replacing the lost hard tissue with a restoration.
This may involve a root canal treatment either because the lesion has
extended that deep or because additional mechanical retention is needed for
the restoration. My experience of "ankylosed" unerupted teeth is that a good
number come under this category and are not true (i.e. bony) ankyloses.

3. So, you have confirmed that these are not the cause and you are sure it
is ankylosed. In regard to the procedure to "shake", "shockel", "free" or
other circumlocution (always referred to as "gentle") that may be used to
suggest an empirically-determined breaking of a small ankylotic
connection, to achieve a degree of movement similar to, or slightly in
excess of, that of a normally erupted tooth. I would suggest the following:-
firstly, be sure that you have a full and heavy archwire that fills all the
brackets and spreads the load to all other teeth in that jaw. When the
surgeon has completed his (relatively simple) task, apply heavyish pressure
to the tooth with a good elastic tie. Understand that this type of ankylosis
recurs with amazing speed, once the pressure lets up and bony healing
occurs. So you have to keep up the level of force by changing the elastic
tie every few DAYS. This way, the tooth moves before bone reforms across
the previously ankylotic site. Essentially this is distraction osteogenesis
on
a microscopic level. I will even call the patient (something I will almost
never
otherwise do) if he/she forgets an appointment, in order to maintain the
momentum and give the tooth the best chance of success - if you don't see
the patient for a month or so, you will have failed again for sure.

Regarding Bobby Cohanim's patient who had lost maxillary left incisors as
the result of trauma and the canine of the same side had become ankylosed
and relatively intruded. Block osteotomy and extrusive orthodontic force
appear to be the direction to go. However, we must recognize that the
desired treatment procedure is a distraction osteogenesis of some degree and
not orthodontics. The forces must therefore be applied and maintained to a
relatively high extrusive force level. This mean having an efficient
mechanism, resting on a wide anchor base, with a good range of applied
force and that the forces be renewed every few days. Cancel all vacations
and make sure the patient comes in as needed - but you may still fail if one
or more of the above conditions is not met. So communicate with your patient
and explain the urgency to him/her.

Paul M. Thomas has blamed the resistant canine in the adult as the cause of
a result that shows "external resorption after a period of time". Mort
Speck
makes the same observation. I would like to suggest that the external
resorption pre-dated and was the etiology of the resistant canine and not
its
cause. However, I accept that it may be difficult to diagnose on a p.a. of
an
unerupted tooth - it looks like a normal cervical radiographic "shadow" in
the early stages.

John McDonald touches on several of these aspects, in the name of mentor
Robert Vanarsdall - i.e. reapplying traction every day or two, seeing root
resorption near the neck of the tooth. He brings in another very relevant
point and that is the penchant of the over-zealous surgeon to expose widely
and to nick the PDL on an exposed root surface (wasn't that how Peter
Shapiro of U. Washington deliberately caused his reimplanted deciduous
canines to ankylose so that he could exploit their subsequent absolute
anchorage potential?) and the possibility of spill of etchant on that root
surface.

None of these need happen if the orthodontist is present to restrain the
Oral Surgeon from being over-helpful! How can an orthodontist accept
responsibility for a result if he/she is not present when a well-meaning
oral surgeon, while providing access to the tooth, also engages in other
"helpful" practices? See pages 35 - 40 in my book for a fuller description
of the many possible pitfalls - each of which can lead to the pessimistic
50-50 failure rate that Paul M. Thomas has suggested.

One final point relates not to orthodontics but to oral rehabilitation. When
a normal canine erupts into its place in the arch, it brings with it a large
amount of alveolar bone which gives the dental arch its characteristic form
in that area. If a palatal canine is extracted without an attempt to bring
it into the arch, this alveolar bone does not develop and the immediate
edentulous area of the ridge is thin, lacking its eminence. Placing an
implant in this area is difficult because of the relative lack of bone and,
even when successful, the final artificial crown must be placed with a
strong buccal tilt or else it will be in crossbite. This is neither
functional,
esthetic nor is it likely to have a good prognosis.

Dear group:

I have encountered a patient who has systematically broken a 16 X 22 SS wire between the upper two centrals.

Here is the setup:
Mixed dentition, Pendex appliance with bands on the 6's, TMA springs removed (Molar distalization is finished), SPEED .018 slot brackets on 11(upper right central), 21(upper left central), 22(upper left lateral). 16 X 22 SS wire from 16 to 11, 21, 22, 26 with open coil spring between 16 and 11. This setup is to open space for right upper lateral which erupted in rotation. I am not worried about the centrals flaring because the boy needs a bit of overjet. Mother is adamant about the fact that he does not do anything that would break the wire. according to her, I am responsible (implying I am using inferior quality materials), etc, etc, etc...

My question is: How is it possible to break such a wire very cleanly just mesial to the #21 bracket? His teeth are not even in occlusion. I've only been in practice 16 years, but i'm not so new at this. Maybe its the City of Montreal water that corrodes the wires... How do patients really break those wires without having access to pliers?

Dear ESCO
a 9 years old male came to my observation with a I Class malocclusion. It
was planned a fixed orthodontic treatment but I warned his parents that
there was a second upper premolar (15) that was late with root formation if
compared with age and with the other teeth (25) and that it could be
impacted even at the end of
orthodontic treatment. Two years later I am going to end treatment, root is
not formed
and it is deeply impacted. and its space is open.
Would you extract it and replace with implant or wait more for root
formation?
Thank you

I just heard something very interesting. At the recent perio meeting in

this was simply to let our colleagues know that this is available through

All the information on INVISALIGN seems to point to non extraction treatment
hardly anything can be done for skeletal problems and for cases involving
maximum or moderate anchorage! Why are all orthodontists so panicky? No one
can replace good knowledge of orthodontics!!Let us see the results and then
comment please! And if it does help in some cases general dentists are more
than welcome to try it! At least then we can work on the really challenging
cases!                        orthod-l@usc.edu wrote:

Dear Colleagues,

In Case you didn't notice it in the general announcement, there will be a two day Tip Edge Course on 5th & 6th November preceding the main Australian Begg Orthodontic Society / Khon Kaen University conference. The cost is $US250. For those wishing to enrol or for further information please contact Dr Colin Twelftree <twelftre@senet.com.au>

INVITATION

The Australian Begg Orthodontic Society (ABOS) in Conjunction with Khon Kaen University (KKU) in north east Thailand are holding the annual ABOS meeting at the Sofitel Hotel and on the University campus in Khon Kaen in early November 2000. All orthodontists and their partners are invited to attend. As well as an exciting scientific program, there will be organised sight-seeing tours of the countryside and the famous silk producing region.

All orthodontists, regardless of the technique they use are welcome and you will be pleasantly surprised to see how diversified and relevant the program is. For instance, Professor John Gibbons from the Department of Pathology at the University of Sydney and former visiting Professor at U. of Colorado and Harvard, is giving two lectures on Recent Molecular Biological insights in Facio-Maxillary Development. Professor Sarinnaphakom from the Prosthetic Department of KKU will be giving one of the two lectures on occlusion; "Occlusal principles for orthodontic therapy"; another lecture is entitled "Bite Force and its Meaning". The full scientific program is on our web site.

The registration fees have been deliberately kept incredibly low and even postgraduate students will find they can afford to attend. This is despite the conference being held in a five star luxurious hotel. It is better still if you are exchanging American dollars or Euros. We have been assisted by the generosity of the 3M Unitek Company who helped print and distribute the registration booklets. Khon Kaen is not on the usual tourist trail so you can experience the untouched culture of this Isaan Region and visit temples, bronze and iron age pre-historic archaeological sites.

There are regular flights from Bangkok to Khon Kaen and these take about one hour. The full social and scientific program runs from Monday 6th to Friday 10th November 2000. There is a pre conference Tip Edge Course

Registration forms can be printed off the web site. www.myorthodontist.net/begg
Our appointed travel agent for flights and accommodation information is Ms Vicky Gilden of Jetset Tours E-Mail sales@jetsetrosebay.com.au
Further information can also be obtained by contacting the President ABOS Dr Morris Rapaport E-Mail braces@orthodontist.net

Dear Andre;
Had the same experience to one of my patient and after thorough interrogation, the culprit seem to be the nail-clipper (a big one though) which the patient managed to insert into the mouth and use all his force to clip off the wires and pulled the pieces out. Can't do anything about it unless he is banned from possessing any nail clippers. Lots of brain washing needed for the patient to reduce further breakages.

Just a thought of may be converting the speed brackets at the anterior teeth with the old type of A-company straight wire brackets (quite a broad one) to reduce interbracket width which could increase the "stiffness" and make it more difficult for the patient to manipulate any clipping instrument successfully.

Hi Alan,

If the embryo of her 8 is still there with normal size and position, the
three molars should be extracted.

I would check rx, if the teeth is in the same position for 2 years , maybe its ankylosed, but even though I would try, having the gingiva cut , like, make a window, and wait a little. I don't know if I would bracket and try to pull it, only looking at the rx would make me decide. If you decide to pull don't use continuous arch.

Dear group,

I'd like to hear your opinions regarding a case. A nine year old girl has a
Class I occlusion with her upper and lower incisors erupted except for the
left-central one. It is still impacted in the maxillary. As shown in the
X-ray, the embryo of her 21 has twisted by 180 degree, i.e. the crown is
upward while the root downward. Are there any alternatives to extraction?
Why? I'd appreaciate your effort in addressing my case.

It appears from your message that the patient is now 11 years old. If there is
more root development now than 2 years ago I would deband (if you are finished)
and hold the space with a retainer. Take annual (or semi-annual) x-rays and
reasses for extraction if the tooth hasn't erupted by the age of 14 or so. TGS.

Subject: bombed out molars

Alan

I would extract. The kid is going to drag 3 bombed out molaars for the rest of life.
I had a case but the girl was older, the 7 wasn't erupted and 36 and 46 were needing endodontics and whole crowns, I opted for extraction and 7's came in nicely, thank God.
You have a more difficult case, because you have a young kid and 3 bombed out molars, even then I would extract.

Dear Marco:

If this patient is only 11 years old at this time and you have opened
space for this tooth, they have nothing to lose by your fabricating a
fixed retainer to maintain the space. The implant cannot be placed
until he is around 16-18 years of age. Realistically, this patient will
not wear his removable retainer faithfully for the next 6 years before
being ready for an implant.

If the tooth does develop and ends up needing some guidance you can go
back in with partial treatment.   The tooth should be followed every
12-18 months to make sure that there is no problem developing. If it
turns out that the tooth requires extraction and implant placement then
this can always be done down the road.

Hope this helps. I am assuming that this patient is only 11 years old
since you made reference to starting at 9 and going through two years of
treatment.

Mark

Marco Capozza,
The patient is 9 years old. Is it imperative to treat now? Can you not wait
till age 13 or 14 and reassess the whole problem, with a much more mature
premolar (and patient!). The boy presumably has many unerupted teeth and,
who knows, maybe something else will impact.
If you have to treat now (although I cannot imagine why, but you are the
best judge of that), why not complete your ortho treatment for everything
except the maxillary second premolar and then retain in the usual way, but
add a special individual bonded space retainer for the unerupted premolar.
Obviously you cannot treat the premolar now and neither would you want to
replace it with anything that may have a poorer prognosis. So, you wait 3,
4, 5 or more years until the premolar has a half to 2/3 root length. It may
erupt, but it may impact - you cannot predict that now.
There is no evidence to support early treatment improving its prognosis. So
why make a 2-phase treatment unnecessarily?

Hi,

I agree with Ted Schipper.

An interesting paper on this appeared in Aust. Orthod. J. Oct 89, titled "Hypodontia in the permanent dentition" by Nik-Hussein. She discusses the term hypodontia in preference to partial anodontia, oligodontia, aplasia, etc.

A relevant feature to Marco's case is in the last two sentences of her abstract, namely, " It is noteworthy that studies showing the lower second premolars to be most commonly missing, have younger subjects. This suggests delayed development of these teeth in some individuals." As editor at the time, I thought her insight into this so important that I elected to italicize the words therein as a warning to we clinicians to be on guard.

As usual, when one becomes aware of things (Goethe: "We only see what we know" ) they are seen to varying degrees thereafter.

Dear Greg

I think it is a big mistake to assume Invisalign is not intending to
damage the image of braces. In fact they seem to be going out of
their way to do just that. Take a look at the ads and tell me the last
time you saw those type of large appliances on a patient. Listen to
what is being said and the viewer is left with the impression that
conventional braces are ugly, cause people not to smile, and are not
attractive. These are neither accidents or unintentional . I have no
problem in looking at Invisalign with an open mind as far as its use in
an orthodontic practice, but I won't delude myself into thinking they
don't really intend to malign conventional orthodontic appliances.

We have been opposed to all forms of retail marketing/advertising for new patients since we started in 1980. Every piece of evidence we have says that retail marketing attracts a very low quality patient with an extremely low (25% or less) rate of case acceptance. Given that experience, our antennae perked up when we saw the Invisalign television ads.

Last week I asked 250 of our client practices to carefully track the credit ratings of new patients coming in directly as a result of the television advertising.

We don't expect anything concrete for another month or so but my first days' report was 14 new patient exams, 12 "C" patients, 2 "B" patients, 0 "A" patients, 2 case starts. Looks like past history is being reaffirmed but I will reserve judgment until I have a much larger response to evaluate.

BTW - A "C" patient is a person with clear and solid evidence (normally, but not always, contained in a credit report) that they cannot or will not pay in an appropriate manner. A "B" patient is in a personally unstable situation(2 weeks on the job as a clerk at McDonald's) or is sloppy in his bill paying habits. An "A" patient is a person without those problems. "A" patients normally make up 75% of all patients likely to visit an orthodontic office.

When this mini study of patients responding to the Invisalign advertising is complete, I will send results to anyone interested - no strings!

In our office we charge an additional fee for a combined
orthodontic/orthognathic surgical treatment. I understand that this fee can
be submitted to the medical insurance company covering the surgery using the
same diagnostic CPT codes that the oral surgeons use. If anyone is familiar
with this and, in particular the procedural CPT codes, I would greatly
appreciate it. Thank you.

I am considering changing from a participating to non participating status with Delta Dental Plan. I am interested in talking with those who have made this change and also those that have not been participating providers and have patients covered by DDP.

I think it would be best to communicate outside of this list for various reasons. My e-mail address is: dstockin@inreach.com

I am interested in how the change affected current DDP patients and also how changing to non participating status affected subsequent DDP patients.

My last accepted fee listing was is 1992 when DDP required listing of orthodontic fees in conjunction with their basing the codes on treatment times. Prior to that, I had filed fees for the few things other than orthodontic codes (exam, x-rays, records, etc.) From 1966 until 1992 I did not file orthodontic fees because my belief was that a filed fee had no affect on a patients receiving benefits. In 1966, a typical CDS orthodontic benefit was 50% with a maximum of $500. In our area, 1966 full treatment fees were in the $1000 range and patients paid the difference. Today, the $1000 1966 fee, adjusted for inflation, would be in the $5000 range.

My 1992 accepted DDP filed fee for a panoramic x-ray is $45. I have tried on two occasions, 1996 and 1998 to raise that fee and have been between 8+% to 11+% above the UCR for our area on each of my filings and resubmissions which included lowering other fees to fit into their formula.

I feel that I want to raise my panoramic fee. I have a new x-ray machine, I double load film and send an original to the DDS, hazardous waste costs, etc. In a recent dental practice magazine, the national median fee for a panoramic x-ray was listed as $63. I know there is an approved DDP panoramic fee of $85 in our area because another office's check was included in a payment mailing to our office and that was a few years ago.

When I took out the DDP fee filing form and decided to try again, it irritated me that they summarily dropped to the 80th percentile for accepting fees. Then, realizing that what I was agreeing to by signing as a participating provider went against many of my beliefs, I decided to consider dropping from being a participating provider.

My administrative person feels that I am making a poor decision, however, understands and will go along and work through any transition.

As I look back, I wish I had never filed any fees. I joined CDS when first in practice thinking that was the thing to do to support private practice. Wow, how different 2000 is from 1966.

As stated above, I feel communication on this subject should be outside the ESCO list.

Hello All:

I finally made my purchase and now own a brand new Dentoptix Ceph unit.
So far so good until you are asked for a copy of the x-ray. Not many
around here go with the email as a source of info so I am having to
print the x-rays. I have an Epson Inkjet and I have a HP4+ Laser
Printer.

My 1st question: What paper have you found to give the most realistic
copy for both the Inkjet and the Laserjet?

My second question: Considering the speed of the laserjet, has anyone
compared the copy from each to find out if there is much of a
difference?

Thanks in advance,

Mark

Dear Andre
At 03:23 PM 13/10/00 -0400, you wrote:

I have encountered a patient who has systematically broken a 16 X 22 SS wire between the upper two centrals. <snip>

One thing I have learnt is that anything is possible... says he with the advantage (or disadvantage) of twice the experience you have :>).

As usual, I agree with Mark Lively. How old was the wire, since hydrogen embrittlement is very real with old stock (>4 years) especially if not sealed away from water vapor?

Tengku's story is indirectly supported too from now on. What makes me suspicious about the continual breakage is your wording "Mother is adamant... " How often do we hear that with non-compliance, e.g. when elastics are obviously not being worn, and a few weeks of Jumpers shows there is no ankylosis, etc. What was it that Shakespeare said, something like "She doth complain too much"?

However, there is the patient's side to be empathetically considered too like the one being reported by me in the December 2000 issue of the WJO, where, by correcting the max second molars with buccal root torque, the boy said his elastics did not make his teeth sore any more. Maybe read the other anecdote about the 53 year old nurse who, with much questioning, eventually worked out that she was slamming her incisors together during sleep, which was stopping the overjet reduction.

The point is that getting a true history is not always easy as per my report in the AOJ. It was about suspected anabolic steroids in a muscular female butterfly swimmer causing loss of alveolar bone around the anteriors about 18 years ago, rather than the archwires. The orthopedic surgeon who operated on her knee was most interested in my hypothesis since he had noticed something odd too. It was somewhat confirmed by another definite steroid report of alveolar loss from post-surgery vertical elastics also in the AOJ not long afterwards.

About 25 years ago, a young lady (?) was having an osteotomy with the hope of improving her attitude at the request of the police sociologist. She was an inmate of a reformatory. Within days of the surgery, she handed me the inter-occlusal wafer.... anything to get attention!! In those days, the wafers were wired in, so the pain to break the heavy wires with a surgically broken mandible must have been incredible -- worse than for those children who dismantle their Jumpers nowadays.

The best story about wire was about 30 years ago. And this is a true, I swear. In those days, extractions were more common and the four-fours had been removed prior to treatment for a boy whose parents were dairy farmers. The study models showed that one upper cuspid was partly erupted. Mother rang just before the banding to say that he had had another tooth extracted by a cow. (Yeah, yeah). So I said could I see him straight away to sort out this (ridiculous) story. When he arrived, there was the cleanest extraction of the upper cuspid you have ever seen. There were no signs of associated trauma around the socket or face!! Mother, a typically sensible farmer's wife, said "He was walking behind the milking cows, when one got a length of loose fencing wire caught around its hind hoof and panicked by kicking its leg. The wire lashed around and went around his eye-tooth and extracted it!!"

Herein, with respect, Andre, ends your bedtime stories.... better than those your Mom told you?

Like Paulo, I have also been concerned about the negative message that the
Invisalign ads are sending. I'm sure they did not intend to do damage to
the
image of braces, but that is exactly what the ads are doing. Invisalign has
great potential, but obviously can't be the right treatment for all
patients.
Hopefully Zia Chishti, CEO of Invisalign, will correct this error as soon
as
possible.

Hi Paul:

Thanks for the info. I have been trying to educate my own patients as
to the limitations of the appliances and that wearing braces today is
not what it was 20 years ago, regardless of what the Invisalign
commercials portray.

As for those calling our office, we have referred them to a colleague
down the street until we feel more comfortable with the product.
"Thousands of patients in treatment" versus "thousands of patients
having been treated" are two different things.

Dear Brothers and Sisters,
    In the Invisalign ad I saw, a man who seems apparently quite happy with
his metal braces is less appreciated by the girl who is wearing Invisalign.
Of course it would be impossible for Align to make a statement about how nice
Invisalign is if the guy were wearing clear-transparent braces with
tooth-colored wire or Lingual braces. In my practice every patient is offered
(without extra cost) the clear braces, and guess what, I do not have a single
adult (practice is 48% adults) with metal braces. What is there to carp
about? So from an Invisalign ad a would-be patient learns about Invisalign
and metal braces and not knowing about clear-fixed or lingual says "At last I
can have my teeth straightened." So he finally makes an appointment and goes
to see the orthodontis who tells him that "HE IS NOT A CANDIDATE FOR
INVISALIGN," however, the orthodontist continues, "I can offer you these
clear-transparent braces and I can offer you these braces that go behing the
teeth". So lads I say make hay while the sun is shining. Cordially my
brothers and sisters, Ted :-)

I have been sitting here on the Invisalign sidelines thinking that while it
certainly wasn't an orthodontic panacea the advertising of orthodontic
treatment of any kind couldn't hurt the profession. Well maybe that's
changed...

I am finding that, like Paul Zuelke, the patients coming in for exams due
to Invisalign TV promotions are hardly the highly motivated patients we
have from our own office based marketing efforts. First, might be the
impression that if it is advertised on TV it must be mass marketed and
therefore "cheap." Cheap is about the last thing Invisalign qualifies as.
And as Mr. Zuelke's informal survey has indicated, they aren't as credit
worthy as our more traditionally attracted patients. Heck, these people were
motivated by an ad on TV. They'll buy anything with the proper stimulus and
probably have already stretched their credit limits. So the ads make it
look quick, easy and cheap. Those are three words that one would never
associate with quality orthodontic care. No wonder that so many of these
patients gather up the information at an exam and are never heard from
again.

Next, and maybe more important was a comment this week from on of my "20
something" patients in conventional treatment with esthetic ceramic braces.
She asked if I had seen the ads for "those new, invisible braces." I said
yes and waited while she told me how insulted she was by the tone and
assumptions in the ad. She said her teeth never looked so good even with the
braces on, and that the people portrayed with braces were getting a bum rap.
So much for Invisalign's marketing strategy. They will need to have a long
talk with their ad agency about who they are appealing to and how to win a
market share without destroying the whole market to begin with.

Sorry for another posting about Invisalign, but I feel better already.

Thanks Paul for the initial evidence that speaks directly to the lack of
business and professional maturity within the Invisalign corporate
structure. This can unfortunately injure many, and perhaps kill a good idea.
Creativity and wisdom are not the same thing.

As was mentioned in another post, the seasoned orthodontic manufacturers and
suppliers have worked within the professional system, generally preserving
professional integrity and credibility. Most of them have grown out of
long-term players, which began with a service and built a business while
establishing trust. This is typically the way "A" people make important
decisions, and in stark contrast to the daytime TV mentality. We have all
seen good ideas come to market independently, the risks to the responsible
professional are higher.

Not as a criticism, but observation ... this quality of decisionmaking
usually comes with age and experience, and it would be unreasonable to
expect a youthful president and CEO to be naturally endowed with it merely
as a consequence of having a terrific idea. A WISE choice would be to humbly
accept the fact that they just don't have the experience in the profession,
and team up with a reputable company that does.

A criticism with a constructive clinical question.

Does Align have the capability to integrate a plane into the aligners??
Splints with the potential to correct occlusal disharmony would be
interesting. It would at least expand the options for TMD treatment. But,
as pointed out earlier, their technology would have to include imaging
dynamic occlusal relatinships. Does Align have any intention of going this
way or integrating dynamic relationships?

Since invisalign is watching, would anyone (from Align) formally like to
comment on the "misquote" about the "horse and buggy" comment. I read the
previous response from Inivisalign, but felt it fell far short of sincere
when I have seen this misquote at least three times in three different
cities about two weeks apart. For those who have not seen this in print, it
is insulting to all orthodontists, misquote or not. Here was the invisalign
response.

"Dr. Lebsack also cites an article in USA today that portrays orthodontics
as
being in the "horse and buggy" mode. In fact, many papers carried that
phrase as a direct quote from my partner, Ms. Kelsey Wirth who is the
President of Align Technology. Let me state categorically that what you
read is a misquote. In fact, what Kelsey was referring to was the
structural difficulties of introducing a transforming change into a well
established marketplace. When the motorcar was first introduced, many horse
and buggy drivers criticized it for all manner of perceived imperfections:
can't drive it on anything but a paved road, needs expensive gasoline rather
than cheap horsefeed, breaks down all the time, requires gears, are ugly,
and so on. Kelsey was referring to some of the reactions we were receiving
from orthodontists who perceived us in a similar fashion. By no means did
she mean to imply anything ill or dismissive regarding the current practice
of orthodontics. The comment was simply misquoted out of context and we
regret if there was any offense taken."

"Simply" or not, insulting. Also, to shrug it off with, "if any offense
taken," really shows a continued lack of understanding of how offensive the
"misquote" is.

In addition, the commercials also are undermining traditional orthodontic
care. Invisalign itself acknowledges that in the end, they will not replace
traditional fixed appliances, yet they deride them in their commercials. So
for every dollar they spend with this advertising tact, orthodontists will
have to spend their time and money (through the AAO and the like) to repair
the damage. Any comment on this from Align.

I too am concerned about the advertising. I have taken the seminar and am
set up to do Invisaligns but cannot see them being a very large part of my
practice. They are very limited in what they can do at this point and so
most of us will need to do conventional orthodontics on the majority of our
patients. Invisalign is not making our job any easier with the negative
images of conventional treatment. Most of my potential Invisalign patients
do not schedule an appointment when they find out the costs.

Dear Colleagues:

At the present time we do not have searchable archives, although that may
arrive soon. However, you can obtain previous digests:

To get archives for ORTHOD-L, first get the index, which will show the name
of the file. To get the index, send email to: listproc@usc.edu

As the text in the body of the message put:

INDEX ORTHOD-L

Once you have that listing, you will see filenames starting with "log" and
a description with the digest number of the first digest contained.

The filename has 4 digits and a letter, denoting the year and month, and
the week of the month. Thus log0002a would be all digests for week 1 of Feb
2000. Each archive holds digests for the week.

To get that archive, as an example, you send email to: listproc@usc.edu

As the text of the message body put:

GET ORTHOD-L log0002a

Dear group,
A 15-yr old male came to my observation with a Class III malocclusion. All
of his first premolars (4) were extracted. Placing the Edgewise appliance
for 14 months, I have corrected his overbite. Last month he returned to me
for a follow-up examination when I noticed something unusual. His labial
gingiva began to resorb at the lower lateral incisor and canine (42 & 43)
with the root exposed. The resorption became more severe in his third visit
last Tuesday. About half of the labial gingiva of 42 and 43 were found to
expose and the teeth in question had no contact with the maxillary 22 and
23.
Question 1: why is there such resorption of the gingiva of 42 and 43? And in
such a degree?
Question 2: what is my next move to tackle the problem best?
I appreciate all your comments.

Hi,

Mark Cordato sent a personal posting to update/correct my "Breakage" posting and our thread is below the lines. As old friends, we have had many personal exchanges over the years -- invariably of benefit to both parties. In this case, we obviously agree that the observation applies to subpopulations (minorities). Thanks also to Joe for ESCO, to be able to read other people's threads.
___________________________________________________________________

Dear Mark,

I suppose this is an example of the downside of abstracting or simplifying... even my own article. That is, all details can become important in diagnosis. However, this is not peculiar to diagnosis, as Hollingdale stated in his introduction to 'A Nietzsche Reader' (Penguin, 1977) "Simplification... is to some extent a falsification."

Whatever the parafunctional theory, as soon as the patient told me about "slamming" her incisors from a very open position (naturally it took a few months of discussions, since I persisted questioning with the hypothesis that she was clenching during sleep), I asked her to wear anterior vertical elastics at night to support the mandible up closer to the rest position. Then -- with the same Class II 2oz elastics -- the overjet reduced quickly at >1mm per month. Yet the overjet had not changed for many many months previously. In other words, the response was similar to applying Buccal Root Torque to some upper second molars.

But on the subject of theory... As opposed to bruxing that uses different muscles and is noisy, I understood that clenching is usually done in protrusion. Teleologically, this could be Nature's way of avoiding the extruded upper palatal cusps in many individuals. Whatever the mechanism, the nocturnal clenching on the anteriors causes ischemia of the perio ligament to slow tooth movement... completely on occasion. It further explains why well-applied Buccal Root Torque, to raise the palatal cusps, redeems incisor tooth movement to normal/optimum rates as covered in my WJO Part II paper.

>There are exceptions and this is where guys like Every with his theory on Thegosis and >occlusion get a run too.

I did stress in the text that the vertical elastics were not to be used in a cookbook manner. The point is, as with every recognized TMD expert I have ever heard, that one needs to listen empathetically and open-mindedly to the patient when the diagnosis is not obvious.

I'm sure I read, but have forgotten the details of, Thegosis and occlusion. Wasn't this covered in an article in the ADJ of recent years?

[Mark OK'ed this personal exchange being posted on ESCO, and his reply included : "I read a book of his (Every), and as he was a Kiwi, I expect there would have been an ADJ article. I suspect it is only relevant to a minority of cases ... but for that minority it is important."]
______________________________________________________________________

PS: Mark, I finally found the relevant ADJ issue in the kitchen... the "Commander-in-chief" is not impressed with where I leave my journals!!

The title itself is rather significant (for others, thegosis = sharpen/whet [Gk]) :
Thegosis -- a critical review. Murray CG and Sanson GD. Aust Dent J. 43 (3):192-198, 1998

I now recall my reaction on first reading it. It was that thegotic theory missed one small subpopulation that is important to us... those patients who sharpen their incisors by Coca Coca and Pepsi Cola. As well as the more obvious feathering of the lower incisor edges, inspection of the lingual surface of the upper incisors will show ledging in the serious addicts of these drinks!! The parsimonious dental literature lulls readers with the bland generic term 'cola drinks'. As well as much sugar and phosphoric acid, the caffeine (added to the legal limit) gives patients headaches for 2-3 weeks trying to kick the habit. I wish studies on white spot lesions would recognize this etiology by careful and subtle (read cunning) history taking.

Barry

Been using herbst for sometime. I belong to Oakstone medical's online
literature review service. Most of the abstracts from the literature
review service are not very supportive of the Herbst appliance. Most
correction is dento-alveolar with a lot of mandibular incisor tipping.

Have any of you
Herbst user evaluated results?

Dear group,

I would like to thank those who responded to my Breakage thread

Mark Lively and Barry Mollenhauer suggested defective wires
The wires I used in both instances were brand-new Unitek 16 X 22 SS from two different batches
Barry wrote:
>How old was the wire, since hydrogen embrittlement is very real with old stock (>4 years) especially if not sealed >away from water vapor?

My question is: Is there literature on this specific subject?

Tengku Sinannaga wrote:
>...converting the speed brackets at the anterior teeth with the old type of A-company straight wire brackets (quite >a broad one) to reduce interbracket width which could increase the "stiffness" and make it more difficult for the >patient to manipulate any clipping instrument successfully.

Good idea but why should we compensate for the patient's inability to be compliant?

The intent of my original thread was to begin a discussion on general compliance and how parents and patients will lie to avoid admitting that they have done something wrong. I am ready to admit my own failures but I still cannot understand how stiff wires can be broken by either naturally occuring forces in the mouth or extraneaous forces from instruments available in the patient's home.

Thank you again to those who responded

Dear Colleagues
I have worked like orthodontist at least for 20 years with good results:
but only this year I had three cases of TMD (temporomandibular disorders)
that are getting worse 4 months after treatment;
I have to:
1) put suddenly a splint and look for a relaxed   position of mandible
(without complaints and symptoms)
2)selective grinding for centric-prematurities
3) wait & see

thanks for your help

Hi Mark,
Kodak has a new printer that prints on a blue film material and the result
looks like an x-ray. The new printer costs arounfd $900. The Codonics
printer which uses a dye-sublimation process and produces a beautiful
printed x-ray on blue film costs $12,000. There is a tremendous difference
in price and quality of result, but when presented with both x-rays, most
orthodontists would pick the Kodak printer and product.

I have an HP4+ and it just doesn't cut it for grey scale graphic detail. If
you want near photo quality, use the glossy Epson paper or equivalent. If
it's a routine dupe, I'd use inkjet paper at a lower quality setting so you
don't use so much ink. The cartidges for the inkjets aren't exactly cheap!

Is it the mode of breathing or the resultant jaw posture? Do a Pub Med search using author names Don Warren, Peter Vig and Sten Linder-Aronson (sp?). I think you will find that this question has been beaten to death in the literature but still rises like the Phoenix for repeat attention.

Dear colleagues,
I am working in a research project with an ENT regarding the oral breath habit and its effects on the facial growth. One of the major problems we have find is how to measure or determinate a patient is an "Oral Breath" case. Does any of you knows an answer to solve this matter in an objective way? We appreciate all your comments.

Dear colleagues,

since three years I have the AJODO, the JCO and the Angle Orthodontist on
CD-ROMs. These were produced by Optimedia, first distributed by Ormco, later
by Unitek.
Now Unitek has stopped to deliver the CD-ROMs, which have become
indespensable in my practice.
Does anybody know who produces and distributes these CD-ROMs now?

I am an Invisalign practioner. I've spoken in favor of the appliance in this
arena before. Most cases are going well. I still have good things to say.

But I need help on this one: an ethical issue that I think will become more
prevalent as we use the appliance more. Here's the case.
25 y/o female. Beautiful - like Janet Jackson. "Hates" the way the upper
central is turned and "Hates" the crowded lower incisors.

Now get this: Overjet is 9mm, molars full Class II. With gentle probing, I
find that 1)She is not concerned with the protrusion of the upper incisors,
2) She is not concerned at all about the overjet, and 3) There is "No way"
that she will wear braces. He job is "too demanding" and she does not want
to be seen in braces (OK boys, don't get your bristles up. That IS who the
advertising is aiming at, after all).

The question is: Do I do the Invisalign to satisfy the patient's chief
concern , or do I say that your case is not suitable for Invisalign? Do I do
the Invisalign case EVEN IF I give a full informed consent about the
limitations of the treatment, the risks of leaving a Class II malocclusion,
the impact of long term stability, AND the caveat that fixed appliances will
be needed in the event she is not satisfied with the results? Because I am
sure I could get this lady to sign on the dotted line if she thought she
could get that incisor in line without braces.

Perhaps we face the same quandries with fixed appliances too when there are
legitimate options (ideal vs compensation, x vs non-x, surg, and so on).

The decision is easy when I can see the compromise may cause harm, or may
eliminate a more ideal therapy in the future.

But when the treatment seems quite harmless, or I know that I can always
resort to the proper treatment if it becomes indicated, the decision lines
become blurry.

And this is where Invisalign is going to present the greatest challenge.
Deciding which cases to do, and which to pass on.

Any comments?

Dear Colleagues:

Thank you for your confidence and your participation in discussions on
ESCO. It is the contributions by members that make this study club
interesting for all of us. Our membership, at over 3,500 worldwide, is the
largest for a service of this kind, but we would like to have even more
orthodontists online. Please inform your colleagues of ESCO, and direct
them to our web-site for automatic subscription instructions:
http://www-hsc.usc.edu/~jzernik/eclub.htm
Otherwise, colleagues can always email us for help at: orthodl@hsc.usc.edu

The Electronic Study Club for Orthodontics is now over 5 years old and we
are ready for an upgrade. When we started out, most of our colleagues were
not fully equipped for email and web communication. We would like to hear
your suggestions, comments, problems, etc, so that we may make ESCO an even
more interesting and productive experience for all of us.

Cheers,

Joe Zernik

Been using herbst for sometime. I belong to Oakstone medical's online
literature review service. Most of the abstracts from the literature
review service are not very supportive of the Herbst appliance. Most
correction is dento-alveolar with a lot of mandibular incisor tipping.

Have any of you
Herbst user evaluated results?

David M. Lebsack DDS MS

Dear David,

I just spent the weekend with Rick McLaughlin of the San Diego McLaughlins
and, while he is not a Herbst user, we both agree that most of what
orthodontists do is dentoalveolar in nature. I would love to assume that I
am a dentofacial orthopedist but other than palatal expansion, I can't be
sure of what happens other than moving teeth. I wish it weren't so.

Warm regards

Class III patients often have a thin alveolar process in the lower anterior
with prominent root contours. The orthodontic mechanics may have been enough
to stress the periodontium to the point of gingival stripping or recession,
especially if there was scant bone over the root surface. I have certainly
seen this before. Plaque accumulation can compound the problem.
Subepithelial connective tissue grafting may give the best option for root
coverage. The interdental papilla height will determine the chance of root
coverage. These seem to have a better chance of root coverage and offer
better esthetics than the traditional free gingival graft.

The lower anterior alveolus of most Class III patients is very thin
(labio-lingually), and gets thinner if the teeth are extruded to close the
bite (see articl in AJO/DO a few years ago in issue focused on iatrogenics).

It is also possible that the upper anteriors are begining to relapse against
the lowers, and / or the patient has a face-sleeping habit.

It would be prudent to begin by decoupling the anteriors. Take xrays of the
anteriors to look for resorption ... if none, note that anterior teeth are
not lost due to labial bone loos, but interproximal.

Gingival grafting (either free or using cadaver tisue) may help cover the
roots if you act soon enough, and there is enough blood / nutrient supply
available.

I wonder if there is a Wilcodontics practitioner out there that has dealt
with this.

Hi,

It may not be in the formal literature, but it is in orthodontic folklore, newsletters and metallurgical literature. I came across it originally when doing clinical R&D on the alpha titanium wire produced by A.J.Wilcock P/L (Aust). Stop reading now if you get bored easily!!

One of my observations about 1985 was that this wire seemed to "heat treat" itself in the mouth as chrome cobalt wires do in a furnace, welder horns, etc. But since it was a gradual hardening over a number of months, it seemed ideal for clinical use. So A.J.Wilcock took a patent out on it and went into the matter. It seemed that their wire (a near alpha titanium) took up hydrogen from the saliva to form titanium hydrides. This would explain the changes. [Totally off at a tangent, this hydrogen entrapment in titanium is being considered as a future means of energy for engines (e.g automobiles) when fossil fuels run low.]

It was then noted that the hardening effect of the archwires was different in different mouths. A Japanese team subsequently confirmed this variability. More recently, with different manufacturing processes, it has become obvious that this wire "grows" in some mouths, which means that a .016x.022" enlarges to fill the .018x.025" slot. It makes it "sticky" to remove after being in the mouth for a number of months. [On another tangent, it is a gentler wire than beta titanium and more easily formed, hence I have used it for years as a finishing wire.]

Anyway, having become aware of changes in this metal due to hydrogen, it became obvious that stainless steel ligatures also became brittle in some mouths. The key word seems to be "some". Remember Goethe "We only see what we know". So on questioning, I learnt of hydrogen embrittlement of stainless steel.

Andre, this possible lack of info on embrittlement in our literature parallels the corrosion of metals due to microbial attack. I wrote a letter to the editor of the AOJ on this in the early 1990s. Much of that information was gleaned from aviation engineering literature. But Matasa has written on it in his newsletter more recently. Metallurgical creep (histeresis) is another phenomenon that is conspicuous by its absence in the literature, but may be discussed at courses.

>Good idea but why should we compensate for the patient's inability to be compliant?

It is actually a good idea to compensate -- for PR purposes. This is why I use fixed Jumpers. The parents love you for it when they have been harassed by us (orthodontists and our staff) for a previous sibling who was non-compliant with headgear or elastics. Remember that the mothers of these children are often harassed by their school teachers, music teachers, camp leaders, etc. So to have someone who will take responsibility, is very much appreciated.

>The intent of my original thread was to begin a discussion on general compliance and how parents >and patients will lie to avoid admitting that they have done something wrong.

Since this is not really covered scientifically in the orthodontic literature, maybe this is where the art of orthodontics comes in to fill in the gaps. And possibly the art of orthodontics includes a similar definition to 'insight', namely, 'the ability to reach tenable conclusions from insufficient data'. On a few occasions it has taken 20 years to determine the etiology of constant breakage. This happened when a former patient came back with her own offspring and volunteered that this child would not pick at the appliance with a fork as she herself did!! These second generation kids are perfect patients because the poor things cannot even get away with white lies, let alone whoppers (e.g. "The seeds in the banana broke it").

Most studies in the medical literature show that all that can be expected is 30% compliance (e.g. pill taking). That is frightening until it is realized that compliance is much better in a private orthodontic office... phew. Well, at least in my private office it is, compared to the public institution I worked in for one half day a week for thirty years. Among other things, I put the difference down to my supportive staff. So you are right, it is not only our ethics, but staff ethics and patient/parents ethics that come into play. However, the most insidious is third party ethics.

Barry

Dear group

It is not against any law to discuss the philosophy of fee as an integral
part of providing excellent healthcare

I do not/ have not /will not belong to any plan including the "dentists" plan
(which is not)

One very simple reason was stated in the last posting which related to time
as a factor in fee.

Time based fee structures are a holdover of the industrial age. A person's
work was limited by physical strength and endurance, and his/her output was
really a measure of horsepower, therefore it made sense to pay for his/her
services based on the length of time input which was a crude measure of work
(effort X time + work). This may be an industrial origin of pay inequality
for men vs women, since males are generally stronger physically, again an
industrial "horespower" concept. Based on this philosophy, one should be
paid more for working longer hours. If this sound like a union philosophy,
it is. The problem with this is the lack of consideration for output. In the
postindustrial age, one person, aided by others and/or machines, can output
far more "work" in far less time. So, what is to be valued, A. the time, or,
B. the work output?

I value the end product. If a Microsoft or Oracle team writes a program
which adds value to an office, and sells it for $100, and makes a profit of
$10, some would call that good business. If they capture a larger audience,
and sell millions of copies, and their profit rises to $50, some would say
"astute businesspeople". Others woiuld say "corporate greed" and use the
argument that it took no more (brain) work to provide one copy or a million,
so the company should only be compensated for the additional labor (time
again) to make additional copies.

One philosophy is an antiquated union argument based on industrial values
A more compelling philosophy is based on excellence, on quality, on doing the
very best one can do for each individual, and setting a fee based on the
value of the service.

Let's bring this around to dentistry. If a company selling orthodontic
appliances suggests fees be based on time, then the longer it takes, the
higher the fee. At first this sounds reasonable, but it fails to account for
the true overhead in individual offices which is derived from the fixed costs
of being in business, plus the number of times clients are served, plus the
variable costs of materials, etc. Practice A may provide an excellent
service in 18 months with 24 actual appointments while practice B may provide
an also excellent service in 30 months with 24 actual appointments.
According to the union philosophy, the practice which spent the longest
length oif time should charge more, while the practice which finished first,
same quality, should charge less.

According to my own personal philosophy, the last statement is backwards.
The one who finished first, same quality, should place a higher value on her
service! I know most patients would agree. And, what about the third
practice which finished in 12 months with a less desirable result? Worth
less, because the value of the service is less even if it was fast. So time
itself is an industrial concept relegated to union workers who punch time
clocks, and attorneys who work 48 billable hours per day ("it all depends on
what bllable hours is...").
The concept of charging for time encourages a prolonged course of work. This
is probably why lawsuits drag on so long. Philosophically, lawyers are
committed to stretching a case as far as it will stretch.

One should ruminate on this and discuss the ideas with staff, because staff
presents most fees. If they are not comfortable with your fees, even proud
of them, they won't present your values.

I hope some innovative companies see the error of encouraging time based fees
when they have exciting, compelling, innovative products which provide
services that patients value and do not divide by hours or days.
