Implants have proven to be a viable option for replacement of missing teeth and for retention of both fixed and removable prosthetics. They do, however, present their own set of challenges. This presentation will address both surgical and prosthetic failures. Topics will include diagnosis and management of complications at the time of surgery, ailing/failing implants, and management of prosthetic failures. A review of pre-operative planning to minimize failure and postoperative complications will also be discussed.
