Hello, what exactly is troubling you? You say "overbite" but you show a side profile photo without showing teeth. When I look at your photo, what I notice that may be what you're dissatisfied with, is that your chin is recessed and doesn't fit your facial profile. With a small chin, your neck isn't as slender and well defined as it should be. You lose the cervicomental angle - the angle between your chin and neck that people notice on profile views. What can be done to improve this? I suggest a silicone chin implant and liposuction of the fat under the chin to really contour and define the area. Or, if you are not interested in an implant, the chin can be moved forward by repositioning the bone during surgery to give the same effect. If it is the actual overbite (teeth) issue that is troubling you, an orthodontist or oral surgeon may be your best consultation as they can recommend braces or orthgnathic surgery (moving the bones of the jaw and face) to reposition the teeth. Please make sure to consult with a qualified plastic surgeon or orthodontist/oral surgeon. I hope this helps! - Dr. Leong
