Can chin implant solve my problem? (photo)

The solution to your problem may be either a chin implant or a sliding genioplasty.  There is a small potential you might need a larger operation called a BSSO.  All of these will change your chin, only the BSSO (if needed, and would require ortho again) would alter bite.  With large chin from implant or genioplasty, your lips will change in a favorable fashion, even if only subtly.  Either way, the first step in an exam.  Bottom line, there is a surgery which can improve your condition, we just need to decide what it is.

A chin implant will help with chin projection and support your lower lip but will not help with the bite issues.Find a board certified plastic surgeon who performs hundreds
of facial procedures and chin implants each year. Then look at the
plastic surgeon's website before and after photo galleries to get a
sense of who can deliver the results. Kenneth Hughes, MD Los Angeles, CA

Augmentation of your chin with an implant could certainly give you a stronger chin, but it would not change the issues with your bite.  

You have a extremely recessive chin and are probably a chin implant candidate.  You also have lip incompetence and have difficulty bringing your lips together.  Sometimes a chin implant can improve this.  Botox to the mentalis muscles (chin) can also assist.I would need to see an Xray to get more info about your jaw and chin.Joe Niamtu, III DMDCosmetic Facial SurgeryRichmond, Virginia

Yes, you do have a recessed chin and are a candidate for a chin implant.  This is a quick, easy procedure with a fast recovery.  It may help a bit with closing your lips. 

A chin implant is a simple and potentially reversable opportunity to improve your appearance. You should highly consider this.
