i have an underbite and i'm going to have a jaw surgery to fix it but there is something i'm really worried about.
my lower teeth protrude about 4 mm infront of my upper teeth and i was wondering will the surgery require moving only my lower jaw or both jaws?
I'm asking you this becouse i haven't spoke to my surgeon about the surgery yet becouse he's busy

so can someone please answer me this question if you had a similar problem?
