Class II patients and functional apliances

[Tiny]

@ Pekay, yes this girl. Amazing result IMO

sorry, what do you want me to say? i don't have much stake in that early intervention theory as I was told that my upper face developed properly, I would be extremely happy if I could have surgery now with a "top guy" but unfortunately due to logistics related problems I'm forced to either settle with a guy that is doing mandibular set-backs in 30mins (wtf?) or walking away completely

witnessed two cases myself 1) mom's best friend her 17 year old daughter (class 2, gummy smile) had surgery at that elite craniofacial surgery in Campinas and has now relapsed (she is 22-23? and her gummy smile sorta came back) 2) Class III girl over at the .br forum had surgery for her underbite when she was 19 and has relapsed completely (under-bite came back)

yeah I deleted the post cause it was bound to only start another argument

underbite patients really should be waiting till almost mid-20's to get treated because their mandibular growth occurs over a much longer time than your average adult

Some of the problem lies in the fact that the facial skeleton isn't fully set until some where between 22-25 yrs of age.

not doubting you (i believe you 100%) but where did you read that? do you remember?

I've read it a couple times, but don't have a source on me at the moment

I was also told in person by a surgeon that it was applicable to the normal prognathic patient, but not me cause my problem is the maxilla. Something something about their growth spurts going well past adolescence and into their early 20's, especially in the mandible, so they relapse and have to get a redo or live with it

ah okay, this girl had her surgery done when she was 17 but it was entirely because of psychological issues. i wonder if she is going to relapse? in my own ignorant opinion that left hand x-ray thingy is sort of bulls**t

couldn't say but wow is that a hell of an underbite! she looks great, but I'd hate to undergo a bsso twice

here's a quick source I did from a 5 minute Google search:

"Another distinct feature of Class III development is
the tendency to display a later, longer, and larger peak of
growth than Class I controls. In a large cross-sectional
study, Reyes et al.22 demonstrated that Class III patients
had a mandibular growth peak approximately 1 year later
than Class I subjects. In males, the peak occurred at 13-14
and females at ages 11-12. Additionally, the amount of
supplementary growth during the pubertal peak was larger in
Class III subjects and lasted longer than that of Class I
subjects. "

"In a similar cross-sectional investigation, using only
Class III subjects and a cervical vertebrae maturation
21 index, Baccetti et al.25 concluded that the average duration
of the growth spurt in the Class III subject was eighteen
months. The authors stated that this duration is
approximately six months longer than that of Class I
individuals. The authors also found changes in mandibular
length (measured as Co-Gn) continued into the late
maturation stages (i.e., after the peak of growth) and were
two times greater in Class III females and three times
greater in Class III males than in Class I subjects."

"Another longitudinal investigation examined 103 Class
III subjects from ages 4 to 20 with no control group. A
series of longitudinal films of each subject varied from 2
to 20 films. Cephalometric analysis yielded results similar
to those found in previous cross-sectional studies. The
average increments of change of the antero-posterior
cephalometric measurements indicated a worsening of the
skeletal relationship with the mandible becoming more
prognathic and the maxilla remaining retrognathic in
position. Additionally, a considerable amount of mandibular
growth occurs following the adolescent growth spurt.4"
