@27F invasive jaw surgery is unavoidable in my case. Yeah Dr Mew tried to push that on me on FB but then I mentioned how much movement I needed and he shut up quickly lol. But what can be avoided is possibly a segmental LeFort. From my other post, I'm leaning that way now. I've been told I'm borderline and it seems that way to me too.
About the appliances, my impression from research is that it works in adults, sometimes. You try it and if you're one of the lucky ones, then great. 1mm a week seems insane though. Bones don't move that quickly. Isn't that the rate for DO even? 7mm a year seems aggressive too, unless you include tooth movement. Half that I'd believe. There is a practitioner a few hours drive from here, I was considering a consult but the reaction from other othos (some whom I trust) was so negative, I don't know. I'm thinking of doing it orthodontically and if it relapses then go down this route. The bones might move over time once the teeth move anyway, at least that seems to be the case since my maxilla is pretty wide despite a long face, very atypical.
I'm considering taking my daughter to Dr Quo in CA, though. She seems to be the only well respected orthodontists treating open bites and narrow arches in young children right now. The approach in kids at least seems to be expand the maxilla and pray the mandible follows. As a girl, she's at much greater risk for TMJ so I'm very motivated to spare her that outcome if I can.
