For some time I am using a lower implant that gives me the possibility to close lower spaces without compromising the anchorage of the front teeth.
As you can see a bracket can be fixed to the implant and a sectional is used to mesialize the first molar. The implant can be adjusted to the anatomy and also in length.
Since sometimes the vertical developpement of the dentoalveolar region near ankylosed teeth is insufficient, this problem can be adressed also by the meens of the implant.
The implant is fixed  with two or three miniscrews through the compacta into the spongiosa and needs only minor surgery.

Dear Dr. Z:
 
My patient, an apparently healthy 14yr old boy of greek heritage, HPI-full orthodontic appliances for the past two weeks, is rubbing the tip of his tongue against the back of his lower front teeth and has created a whitish lesion which is some times like a blister and the size of two apple seeds, according to the Mom.  She thinks it may be an allergy and says it is similar to occurences in previous years at which time he was getting sick with a virus or cold.  She has tried Orobase ointment and says the lesion is stressful for him.  What can I tell them??---Bart.

I have been a follower and fan of ESCO almost since it's inception 
There  have been many instances whereby members would like to communicate with actual photo or ceph examples of their problems and have been limited by cumbersome email size and system restrictions.
The new cephX online data base and tracing system solves all those communication problems. You even do not have to be a subscriber to cephX  to access the photos and x-rays of any patient that the subscribing doctor allows sharing permission.
All you need is a computer with an internet connection
In addition it is a great service for eliminating the hassle of tracing the ceph yourself and viewing any number of cephalometric analyses.

Dr. Stucky,
 
I had a patient that came up with this irritation, I ask him to not wear the appliance for a week and then change the cloth covering the chin part.  It worked.
But I had in mind to ask help of an allergy specialist in case things didn't worked out well.

Dr. Joe,
 
I too have seen those expansion actions being lost through time,  but I discovered that if I keep the force about 6 months,  chances get higher
to success, but even then I worry about the muscle force.
I think those clients in the end should have a hawley that has a wire from 6 to 6 to keep muscle force off.

To: "'The Electronic Study Club for Orthodontics'" <ESCO@LISTSERV.UIC.EDU>

The problem of skin irritation with facemask therapy has been a persistent problem which can significantly impact patient compliance and subsequently the clinical result.   In the December 1999 JCO, a Korean group published a case study using a “Tandem appliance”.  I have made a few modifications of the original design and have had excellent results that are comparable to the results with a facemask.  I’ve completed about 15 cases (with before and after records) and have published it in the April 2003 JCO.  I have included a hyperlink to the article and have no financial interest in the appliance.

To those interested. Gene Roberts' technique of the mandibular retromolar implant is outdated given the current deviced available. If you look at the date of the paper it was at least 10 years ago. He was using prototype implants (later off the shelf) to provide "indirect anchorage to protract a molar. Today, you can use one of the devices which is cheaper, smaller, can be loaded immediately and used for direct anchorage.

Subject: Preliminary review of several medium to high-range digital cameras

*** See attached file (cameras.xls)***

Many orthodontists have been confronting problems with choosing the right kind of digital camera for intraoral photography. In the attached Excel Spreadsheet, we present a preliminary review of several medium to high-range digital cameras.

We would like to call your attention to the new Minolta Dimage A1 5MP camera. It's based on the design of Minolta 7i and 7Hi. But the shutter speed, aperture range, white balancing all get improvements. In addition, Minolta Dimage A1 5MP camera has the world first anti-shaking system that can make intraoral photography much easier. Considering the relatively low price ($680 currently on the market), this is definitely worth considering.

Canon EOS 300D (Rebel) produces the best image quality. But the lens are optional, which may cost a lot. Also, this camera is a PRO SLR camera. It may not be so easy to use and handle.

The standards used to select the six cameras are as follows:

1. Market Price < $1000. Therefore, most pro-SLR cameras by Nikon, Canon, Leica and Olympus didn't make the list.

2. Resolution > 5MP.

3. Must use a high-speed and inexpensive CF memory card. Therefore, SONY cameras didn't make the list.

4. Must have relatively high customer review. Therefore, those Kodak and Fuji low-priced 5MP cameras didn't make the list. 5. Must have features and attachments for intraoral photography.

Most data were collected from camera manufacturer websites. The reviews and comparison data were collected from dpreview.com and imaging-resources.com.

Please open the attached Excel spreadsheet for more information on our review.
