Hi Jose
 
I mentioned in my email on ESCO, that force whose amount is less than 400g. per side have been used, I'm fully convinced with what you have said about that forces which are expected to influence on the aspects of teeth on an intrusive effect. However, I coincided a case of "Long Face", Class III, and "skeletal" Open bite, that case had been treated previously by surgical retraction onto the mandible, however, I found out later that the insertion of Chin-cup with forces about 350g. per side had been so helpful as it compensated the recurrence effect of the structural mussels. In spite of that, the effect is still orthodontic and not orthopedic.
That case had a better consequence later.
As for that, I mentioned a little higher average than what you did, nonetheless, I think it's not a matter, as it depends on each case and the way of forces dissipation.
Thank you.

Dear Dr. Kahn,

I think a response is dependent on age of patient and other factors 
such as occlusal classification, crowding, other missing teeth etc.  What do 
you mean by lower implants?  If you mean one of the temporary screw or 
plate systems, then it may make sense to try to protract the second and 
possibly third molar or otherwise use the space in the process of treatment.  If 
you are asking about the use of osseointegrated fixtures in the retromolar 
area (eg as Gene Roberts has described) then this makes little sense.  
Single tooth implants are reliable restorations.  Why not restore the area 
with a single tooth fixture rather than fiddle about for a considerable amount 
of time trying to drag a molar forward? Unless there is another indication 
for orthodontic treatment, using an osseointegrated fixture as anchorage to
simply close a molar extraction space is not good economics.

Kindest Regards,

Dear Group,
Does anyone has experience with lower implants for closing missing 
first molar spaces? I have used palatal implants for anchorage, but I have 
not used lower non-dental anchorage. I have many patients with missing 
lower first molars that would rather close the space than restore it. Any
experience you can share?
Thanks,
SK

Subject: Screw implants
To: esco@listserv.uic.edu

Hi.
With regard to the question on screw implants, I am currently using them on a few patients. The main problems I have encountered are:

1. If the screw head is near or in sulcus mucosa as opposed to attached gingiva, the tissues get irritated and grows over the head.
3. The screw needs to be placed in good quality bone, e.g. where the maxillary molars are absent and the sinus dips down, you cannot place a screw on the ridge. However, you can place it off the ridge on the palatal side, the bone is thicker and more dense.
4, Position and access. If a screw is placed distal to a maxillary molar with the intention of moving this tooth distally, as the tooth moves distally access to the screw becomes more difficult. Leave yourself adequate space.

Hope this is of some assistance.

Subject: Extraoral appliances for adults
To: ESCO@LISTSERV.UIC.EDU

After reading you comments about "chin cups in adults" and the lack of reports in the literature supporting that technque in adults, four thoughts came to mind:
 
1. most adults, at least in the West, wouldn't probably wear a headgear of any type enough hours to make them work
2. is eight hours really theraputic?  seems like we tell kids that that is really not enough to make adifference in so far as elastics are concerned
3. is what is really happening just a lack of growth in adults and therefore the post op changes are less than in a teen. I personally believe that to be the case.  Many high angle adults seem easier to treat and control the vertical on than growing patients.
4. going back to 1. above, if you are really convincing your adult patients to wear a headgear, are you in some way related to the President of Syria, Bashar al-Assad, and have the use of his Secret Police?  :-)

PS  it is great to be back!

Hello Everyone !! nice to hear you again !
 
Does anyone have an experience in "corticotomy assisted orthodontics and alveolar reshaping ?" (so-called "Wilckodontics") for ultra-fast treatments of adults ?
Have you ever used a single tooth corticotomy, lets'say around a second mandibular molar, to protract it into the space of the first molar ? or to move an ankylosed tooth ? (I don't understand the need for a distraction device in this last case ! ref : "Orthodontic fine adjustment after vertical callus distraction of an ankylosed incisor using the floating bone concept" Kinzinger et al. AJODO nov. 2003) or do you limit it to larger sites (sectors for example) ? what kind of bone grafting do your surgeon use, when he makes a reshaping ?
 
For those of you who never used it, what are your feelings about it ?

Would anyone be interested in future postings about how to use this aid?  In its pure form, angles and distances aren’t measured.

Between March and May 2003, there were twelve matches for the archive search "SASSOUNI."  However, only eight of them specifically relate to the mechanics; Paul Johnson labeled these eight: Sassouni one to S 8.

S 9 to S 12 will follow if anyone will respond to: p8johnson@yahoo.com indicating that they are finding the material worthwhile.
