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.
第三磨牙的外科拔除是普通牙医和口腔颌面外科医生都常进行的一种手术。虽然这种情况很少见，但医源性牙齿或牙根碎片移位到相邻筋膜间隙是一种已知的并发症。本病例报告详细介绍了使用术中导航从下颌第三磨牙的舌下间隙中取出移位的根尖的方法，以尽量减少手术探查。口腔颌面外科医生在计划取出移位的牙齿、碎片或异物时应考虑使用三维导航，以尽量降低手术并发症的风险。
