Hi , yes, impacted 5mm and downgrafted 5mm.
I (now) am told downgraft less than 7mm is always going to produce lip drop ..before I didnt have this problem as I was camouflaged (teeth were aligned outwards ) after de - masking- and 5mm impaction . I have a narrow teeth arch as I had ortho extractions so my surgery plan was just too conservative (dr didnt take that into account) I said O thought 5mm is not enough my orthodontist as well but he insisted overimpaction is the worse thing that can happen. He admits it is esthetivally a bad result but also saying he does not see it as a reason to re-operate..
Ok so correct me if I'm wrong, but you're saying you had a 5mm POSTERIOR downgraft and 5mm ANTERIOR impaction?
This was hard to read, sorry.
Side note but related, I've been told by a local type max fac that for every 3mm maxilla forward movement, you gain 1mm in tooth show. Therefore, he thinks I should get anterior impaction despite a current 'perfect' amount of tooth show, because of his proposed ~5mm advancement to the maxilla. But when you impact the front where there was literally facial soft tissue connected to those hidden gums you're impacting, I would think your your whole mid face and lips would naturally sag down before it reattaches to the bone - like what maybe happened to the OP. It seems like a bad gamble to try to manage soft tissue, in the case of post op excessive tooth show, by adjusting the skeleton. Tooth show is represented in like 1-4mm, and I'm pretty sure no doc has confidence in soft tissue movement within that range as a result of boney surgery.
I mean unless you're removing excessive gum show as part of bimax, isn't it a fools game to try to manage the post op tooth show with class 2 skeletal bimax corrective surgery?
