Mr.Charlie Ruff
I think you didn't read well what I mentioned, I said that I used the Extra-oral appliances as a heuristic means, on the phase of retention, in some cases, to help in preventing recurrence. The cases are only three, as I remember, one of them had been after a surgical correction and after that everything had been OK about the callus formation.
Those are not during the hours of working, in fact that had been recommended on NIGHT only and as a HEURISTIC action and a helpful mean, on other word, an additional mean to compensate the influence of facial structures in some peculiar cases especially with mouth breathing, and open bites. What's more, as to inform the intrusion movements on some long-face cases.
What's mean, it's here not an ORTHOPEDIC influence, in that idiosyncratic cases, the influence is only on the aspect of teeth, and I received an Email from an orthodontist in Brazil whose name is Dr.Jose Luiz Villaca Avoglio, who informed me that he used such appliances with forces between 150-200g per side to gain an orthodontic movements.

Subject: Re: Screw implants
Dear Kim,
Thanks for your answer. I have resolved all my maxillary anchorage cases by using a midpalatal implant and a TPA, attaching it to whichever teeth I want to anchor from, it works really well.
My problem is in the lower arch. I have read and re-read Dr. Roberts article and I cannot figure out how to do it. What kind of implant to use and what appliance design... I need to inmovilize the second bicuspids, but I do not know what kind of appliance I can use to connect the implant to the tooth. It looks like most designs would interfere with the occlusion. It seems like Dr. Roberts connects the implant subgingivaly, but that would bring about potential problems, if anything breaks or becomes detached, surgery would be needed to re-connect.
Any advice for the MANDIBULAR arch?

Many times over my 20+ year orthodontic career, I have seen almost a complete relapse of rapid palatal expansion.  I'm talking early stage treatment, usually with a Haas type fixed expander on kids sub 10 years old.  The activation is usually in the 8mm range, and held for 4-6 months post activation.  Every so often I will see a complete relapse of the expansion and do not have an explanation for this.  I have theorized that there may be a sub-mucosal cleft, or just very thin palatal bone.  I, however, haven't seen anything in the literature to support this. 
Question is, am I the only one who has seen this phenomena?  If not, any screening methods that might predict a questionable result?

Hello Everyone,

Does anyone have suggestions for chin irritation problems with a patient
wearing a facemask?  The chin is getting red and irritated and she is 
not wearing the facemask because of it.  It is the Petit type of facemask 
and I think the padding is presently the type of flannel-like material called
moleskin.  We replaced the original padding that came with the facemask 
with this moleskin, however, the chin irritation persists.

Thanks so much for your help,
