Is orthognathic surgery possible while not wearing braces? (photos)

When I was much younger I had braces twice to correct my overbite. The orthodontist recommended orthognathic surgery, but my parents felt I was too young and I was too young to make my own decision. Now I am 23 years old and am unhappy with my overbite. I am seriously considering orthognathic surgery but I do not want to have braces again. I had them for 7 years and do not want them. Is it possible to have the surgery without braces?
