I had upper and lower jaw surgery as well as a genioplasty on February 3rd for condylar hypoplasia and a 4mm overbite. My right side had grown longer than my left so not only did my jaw have an asymmetric appearance, none of my teeth touched on my right side when I bit down. The ten days of being wired shut with a splint were absolutely horrible but as soon as those came out everything has been smooth sailing since. I still have a small amount of residual swelling in my lower cheeks and chin but it is almost all gone. I also have numbness on the lower left of my chin and lip as well all of my teeth are completely numb. I am so glad I had the surgery done, I can already feel a huge difference in my bite and the by product of improved aesthetics is nice too :) I have about another 3 to 6 months of braces, thankfully most everything lined up perfectly for surgery so my total time wearing braces should only be about 18 months.
The top row for both sets are my before and the bottom row is my 3 weeks after.
