Will I benefit from sliding genioplasty or jaw surgery? (Photos)

Thank you for your pictures.  If you have dental alignment problems, a deep mentolabial crease and poor chin projection then I would recommend an evaluation for lower jaw surgery +/- a sliding genioplasty.  A chin implant or sliding genioplasty alone may negatively accentuate your mentolabial crease.  Best wishes.

The answer to this question depends on whether your orthodontic treatment will require lower jaw surgery. If the treatment of your teeth does not require corrective jaw surgery, then a chin implant or genioplasty can be performed. In either case, jawline liposuction would help provide a youthful well defined jawline.

Yes, after the bite issue has been fixed, your chin can be augmented with implants. This will help to take up some of the slack in the skin along your jawline. When well placed by an expert, a chin implant can last for decades or a lifetime. You can choose a chin with will give you a better projection and smooth the jawline. I hope this helps.

The short answer is your orthodontist will evaluate your teeth and bite.  If your overbite/deep bite cannot be corrected with braces, than you many need jaw surgery to correct your bite.  This will also effect your chin position.  If the bite is OK when the teeth are aligned, than your chin may be augmented with a genioplasty (either moving the bone or placing an implant).

if your bite issues are going ti be solved by orthodontics, then the chin can be augmented by whether an implant or a sliding genioplasty. Given your relatively small horizontal chin deficiency, I would choose an implant for your chin augmentation.
