IAmA 19 y/o male who had surgery on both jaws 6 months ago for a >1.5 cm Mandibular prognathism (Underbite). (Before/after pics!)
Hi Reddit. I've just recently discovered of this section of Reddit (and Reddit as a whole) and I thought I could contribute.
In brief: In october 2011 I had surgery for my underbite that I have had for almost all my life. My underbite at the time of the surgery was about 1,6 cm from the upper jaw. It was corrected by relocating my upper jaw as far as possible (about 1 cm) and then the lower jaw was pushed back for the remaining 6 mm. They had to saw my upper jaw into two pieces to pushed it forward and to expand its width so it fits my teeth of my lower jaw. I had a fixed jaw for 6 weeks after the surgery.
If there's anything you guys wonder that I could answer, AMA.
