Chin implant incision inside the mouth not healing. (photo)

The photo is a bit dark to be able to see the chin implant in the photo, but if the implant is exposed through the incision in your mouth you should return to your surgeon to be evaluated.  In the normal healing process, the implant should not be exposed through the incision.

I am hopeful you have seen your surgeon by this point.  You have an exposed implant.  If is for this reason and others I prefer the submental approach (less likely to have exposure, less likely to get infection, less likely to affect mentalis muscle function, etc).  This also looks like a silicone implant.  You will likely have to have it removed.  Let the tissues heal.  Then have a sliding genioplasty (via a transoral approach) or a porous polyethylene implant placed via a submental approach. 

If your implant is indeed exposed in the wound it will not heal on its own.  You need to see your plastic surgeon ASAP so that they can either remove or attempt to salvage the implant. It is difficult to say which is best for you over the internet, hence why you need to see your plastic surgeon now. Best of luck.
