Retrieval of Displaced Third Molar Into the Sublingual Space Using 3-Dimensional Navigation Assistance

Surgical removal of third molars is a common procedure undertaken by both general dentists and oral and maxillofacial surgeons. Although rare, iatrogenic displacement of the tooth or root fragments into adjacent fascial spaces is a known complication. This case report details the retrieval of displaced root tips from a mandibular third molar into the sublingual space using intraoperative navigation to minimize surgical exploration. Oral-maxillofacial surgeons should consider using 3-dimensional navigation during scheduled retrieval of displaced teeth, fragments, or foreign objects to minimize the risk of surgical complications.
