The deficiency in your mandible is not so much in the chin or mentalis region, but further back in the body of the mandible. Your chin or mentalis region of the mandible actually projects quite well. It’s the mandible itself that doesn’t have enough projection. Most likely, you have a significant dental overbite. This shows because your upper lip has significantly more forward projection than the lower lip in profile pictures. Jon advancement surgery is fairly involved and most people are hoping for a softer gentler approach. As a plastic surgeon, I think oral surgeons are sometimes a little better at getting a really good assessment and understanding all mandibular surgical options. There are also plastic surgeons who have extensive experience with different forms of mandible advancement, including chin, implants, sliding genioplasty, and jaw advancement. My best recommendation is to consult with both plastic surgeons and oral surgeons in your community. If you opt for augmenting your chin with an implant or sliding genioplasty, then you may have an over projecting chin. You’ll find different people have different opinions for this.Getting a quality assessment for this can be a little challenging.I tend to see the mandible itself, and the chin as only part of the mandible. understanding if the chin is the problem or the entire mandible is the problem helps differentiate who’s going to do better with what procedure.
