Is a ​Chin Implant or Jaw Advancement better to treat an overbite? (photos)

you have whats called mentalis strain. thats seen in class 2 or open bite patients as they contract their mentalis muscle to close their mouth. This is what you are doing. You need a lower jaw surgery to correct this. Chin implant is just covering up the main problem being a bone issue. Some surgeons tell you to get chin implants but in reality Oral Surgeons treat this all the time and we realize its a bone problem and thus just putting in a chin implant is not going to properly correct the issue. Get a consult from a oral surgeon. 

An overbite is best treated with a jaw advancement surgery. Sometimes upper jaw and the lower jaw surgery is performed. Jaw advancement surgery is performed  as an inpatient procedure a hospital. A chin implant is inserted for purely cosmetic purposes to give more projection to the chin area. It will have no bearing on the dentition/ overbite. Chin implants are manufactured in a variety of sizes and shapes, are inserted through a sub mental approach under local anesthesia as an outpatient procedure.

I do not believe the chin surgery would help closing the lips together.  The jaw surgery should be done, particularly if you have any bite issues.

It's important to know that a chin implant will not change your bite in any way. Cosmetic facial implants merely change the shape or position of the chin. However, your teeth will still fit together in the same way. There are jaw procedures that can both change the position and look of your chin as well as the way your teeth fit together. However, a chin implant will merely change the balance of your face on profile and, to a lesser degree, the front view. I hope this information is helpful.Stephen Weber MD, FACSDenver Facial Plastic Surgeon

A chin implant is to project the chin forward.  Your chin is a bit recessed and would benefit from projection.
