Question

I have a consultation booked for a genioplasty procedure with my oral maxillofacial surgeon in January. To give some context, my bite is perfect since I just took off my braces. I know for sure I am going to need not only horizontal advancement, but also vertical. My question is, will they need bone graft from my hip to fill in the gap between my jaw and chin bone when they vertically advance it?

That being said, different surgeons have different methods and it is possible that the surgeon you chose may use grafts more frequently than others. This is a question to definitely bring up at your consultation!
