Chin implant stability with applied pressure or blunt force due to martial arts (bjj and boxing)?

Typically, once a chin implant is healed after about 8 weeks and it is in good position, then it is as solid as your normal mandible or chin and jaw. A strong blow to the area of the chin implant will not displace the implant unless it is strong enough to break your jaw. That being said, you should always protect your mouth area when engaging in Jiu-jitsu to avoid other injuries to your face and chin. Good luck with your activities.

Once the implant is fully encapsulated (healed), there is little chance that the implant can be displaced performing martial arts of kickboxing. In addition, many surgeons like myself stabilize the position of the implant with screws.

The combination of intraoperative screw fixation of the chin implant and the postoperative development of a tight scar capsule around the implant, the risk of implant displacement with any substantial force is very low. Having been asked this very question many times, and it is a legitimate theoretical concern, I have yet to ever see or even hear of a patient where this has actually happened.

Any form of implant, or even a sliding osseous genioplasty with titanium plate/screws may become displaced if enough force is applied to the area. In addition, disruption of the surrounding scar or overlying soft tissue damage could cause infection or exposure of the implant. These complications may occur even in patients who do not do any sort of contact sports.
