I had braces when I was 17-19 to correct an anterior open bite and a class II malocclusion. The braces mostly aligned my teeth, but did little for my weak chin, which I'm insecure about (particularly since I've got a pretty big nose). Surgery was suggested to me at the time, but my bite was functional, so my parents said no. Would I be a candidate for a chin implant, or is it worth looking into maxillofacial surgery? If I do, is it likely that I'd have to have braces again?
