I have mild assymetry of the jaw. The mandible is shorter on the left side, and longer on the right, and so my chin is also placed slightly left, my left jaw sticks out. I have an apparent crossbiton my left side too. I have been told I can get orthognathic surgery for this, but this will involve 2years of braces. Is there any way i can have this done in a shorter period of time as i am in my mid-20s already? Any alternatives? calium hydroxyapetite? And will i be able to play sport after this?
