Healing of a cyst-like lesion involving an implant with nonsurgical management.

Numerous reports primarily in the implant literature outline the loss of an implant claimed to be as a consequence of endodontic pathosis from an adjacent tooth. This case report outlines the resolution of a large cyst-like periapical lesion that resolved with nonsurgical management when the canal was dressed with calcium hydroxide on 4 occasions because of persistent intracanal exudate. A favorable healing outcome was achieved for the affected tooth and the implant. This report adds to a growing body of evidence to suggest that implant retained crowns are not vulnerable when an endodontic infection occurs in an adjacent tooth.
