Abstract

Endodontic procedures can result in various complications. Separation of the endodontic instrument is a common complication of incorrect use or overuse of the instrument. However, a separated endodontic instrument may hinder cleaning and shaping during endodontic treatment procedures, which can potentially impact prognosis. Therefore, it is necessary to manage this complication by removal of the separated instruments from inside the root canal. Although several devices are used, nonsurgical removal for retreatment remains difficult. We report the case of a failed attempt to manage a separated endodontic instrument nonsurgically by a private dentist, which resulted in extrusion of the instrument beyond the root apex and its migration into the mandible. We describe a novel surgical approach involving intentional tooth replantation combined with alveolar osteotomy. There have been few reports on the management of separated endodontic instruments that were pushed out beyond the root apex. Our novel surgical approach suggests a technique for the potential removal of a separated endodontic instrument extruded beyond the root apex. (AU)
