had braces as an early teen to align teeth&correct bite.I have always had/hated my weak chin(underdevloped mandible). Considering chin implant but think BSSO surgery would be more correct.To make matters worse i had a baseball injury which led to me losing a front tooth and now having a bridge on 3frnt top teeth.weak chin always makes me very self conscious as a result i tend to push my lower jaw forward.can i have mandible advancement surgery and just have braces to move my bottom teeth back?
