Bisphosphonate and Chin Implant? Will is osteonecrosis?
Doctor Answers 3
In our practice, we have never seen osteonecrosis of the jaw or mandible from a chin implant. We have been using Implantech brand of sillastic chin implants for over 25 years with an excellent success rate. For more information, diagrams of the implants and many examples, please see the link and the video below
Chin augmentation concerns
The question you ask is a very good one. It is well documented that patients who do take bisphosphonates are at risk for osteonecrosis. Further, it is well known that there is some bone resorption in the region of the chin augmentation. There are reports of triggering events patients who have undergone dental implants in which drilling into the mandible or maxilla is performed. In our practice, and in discussion with my colleagues, we have not seen a case associated with a chin augmentation. I hope this information helps you as you make the right decision for you.

Any chin implant including silicone and goretex has a chance of getting a misshaped chin; however, this is not difficult to fix and does not result in biocompatability of the bone. In conclusion, if you do not any underlying bone disease, an implant placement on your regular chin bone wouldn't cause any problem.
