Doctors have said that you should only worry about a jaw implant breaking if you were involved in a high-impact injury, in which, your jaw would also have broken even if you didn't have an implant. In the case of a high-impact injury, such as a car accident, would having a jaw implant make the injury worse? I can imagine the implant's fractured pieces to cause more damage to adjacent facial features, viz. would EMS have more difficulty in treating someone in a car accident with a jaw implant?
