Late Implant Failure

Although dental implantology has come a long way in recent years and the procedure is now known as one of the most widely successful dental procedures that can be done, failure still unfortunately occurs. Implant failure is typically separated into two broad categories: early implant failure and late implant failure. Early implant failure is often caused by issues like a contaminated implant, infection, excessive trauma during the surgical procedure, or lack of primary stability of the implant hardware. Late implant failure is less common, and have fewer causes. Generally, once a patient is out of the woods of early implant failure, the chances of late failure are low. However, traumatic occlusion, occlusal overload, and dental cement that is retained subgingivally. Late implant failure typically occurs within one to three years after the placement of the implant. Bruxism, or nighttime teeth grinding and clenching, is a common cause of late implant failure.
