We all seen the best results from bimax, and if you want that your bimax to actually ascend you from front and side then you need to reach up to a few of these criterias.
criterias to actually ascend from front:
1. You need to have decent jaw width(black) at the gonions( wide jaw), both good examples, right has outward gonions(unfortunate he has short ramus), jaw implants look shit so over if you dont have.
2. Good vertical height across the whole mandible(long ramus big part of it), but if you got too much you will be ogre( very bad). black box is good, red bad:
3. you have a gummy smile(impaction even if it comes some with downsides) or little tooth show( downgraft case, sfs)
4. you need to have bite issues, extreme overbite(7 mm +), underbite, deep bite, or anterior open bite(get your condyles checked).(you can create via decomp)
5. big nasolabial angle and the lip being far behind your nose. this means that you can get a big change on the lips from front movement. the higher you have the greater the change possible
if you dont have all of these then bimax will not change front for you at all.(overbite could be created if you are decompensated somehow)
side profile criterias:
side is cope we know most people can ascend with bimax from the side even most psl gods glazed on this site. so dont even bother if thats the only thing unless severe retrusion. And also the front criteria is enough to understand if its worth. But for function side is ofc very important
Okey now, lets look at some bimax results and there skeletal disposition and the reason why the result became so good or why its not so good.
Lets start with gustavo, Alfaro bimax case, the most famous bimax result online:
lets look at his skeleton, which explains the huge transformation:
Lets now look at another alfaro case which didnt have equally good ascension, but he still had a sfs.
As we can see from the front he didnt have as much of a overbite or retrusion.
Because he didnt have much recession the lower jaw didnt became more vertically long as it wasnt hidden away behind a huge overbite or deep bite as in gustavos case. But he did a vertical genio which i think was a mistake
lets look at his bones and compare to gustavos:
Lets look at the standard recessed case, which has a functional issue. But he doesnt have a gummy smile or much short face syndrome. This makes his front appear the same almost. As we also can notice is that more forward projection will make it seem like its less width on the mandible because of perception.
huge side ascension:
almost nothing changed from front because of no sfs or excess gummy show:
lets look at the bones:
lets look at some more of the most famous bimax cases with the biggest asensions.
lets start with raffaini case:
He got a relatively big overbite, where his lower mandible is hidden because of it. clear indicator is that his chin is far back behind his chin.
from the front he ascends hard when his overly short chin and mandible is coming forward to make his his lowr third seem normal height and not hidden.
his skeleton:
another raffaini case, extremly good base for bimax:
retruded both in the lower and upper jaw( huge nasolabial angle, his upper lip is far behind his nasal base, which makes it possible to go huge on the maxilla and mandible)
From the front his lips become more supported with the huge uppr maxilla movement, and his lower jaw hidden by a big overbite is now in the view.
lets look at his bones, as we can see have the perfect base, and he also gets huge movements which makes a big diffrence:
side note: i dont account on other failos you have like, huge nose, bad eyes, bad phil or whatever that is not addressed primarly via jaw surgery.
side note on the gustavo case, he got severly underadvanced compared to his plan. but yea the front still looks really good. But just shows how unpredictable the surgery is :
