Decision Making For Retreatment of Failures in Dental Medicine: Implant Failure

A 41-year-old female patient presented with purulent exudate coming from the right nostril and from a dental implant placed after maxillary sinus elevation 2 years before. The implant was mobile and painful, and an endodontic lesion was also present next to it. Treatment was completed in just two surgical phases. The first phase eradicated the infection by removing the infected implant and endodontically treated tooth and closing the oroantral communication. The second phase involved simultaneous sinus elevation, implant placement, GBR, and immediate loading to reduce the healing time. This clinical case shows the potential for tissue regeneration even after iatrogenic implant treatment.
