title: Resection of a sapphire endodontic stabilizer due to perforation of the maxillary sinus: report of a case.
abstract: A case is presented which involved resection of a sapphire endodontic stabilizer in a maxillary cuspid. This was necessary due to its perforation of the maxillary sinus. The implant was not readily identifiable upon viewing the preoperative radiograph and could only be resected using a diamond bur. Because of its limited degree of radiopacity, the use of sapphire as a material for endodontic stabilizers may be questioned from a diagnostic standpoint.
