I have a good bite already but I do have a mid-facial protrusion and I would prefer if my maxillary profile were more retrognathic. My teeth are already meeting vertically as they should, though....so I imagine preparing my teeth for jaw surgery would be detrimental, creating chewing problems I have never had? i know jaw surgery is performed for cosmetic reasons all the time though for transgendered women but they are altering their mandibles to look less masculine. My aesthetic needs are different.
