Iatrogenic displacement of a tooth or tooth fragment is a rare but well-recognized complication that occurs during exodontia. The most common sites of dislodgment of a mandibular third molar fragment are the sublingual, submandibular, and pterygomandibular and lateral pharyngeal spaces. Removal of a displaced tooth from these spaces may be complex due to poor visualization and limited access. A thorough evaluation of all significant risk factors along with precise localization of the tooth by clinical and radiographic means should be performed to prevent untoward complications. This paper reports two cases of iatrogenic displacement of mandibular third molar teeth, in the sublingual space and lingual pouch. Both the cases were managed intraorally under general anesthesia, and the postoperative healing was satisfactory and uncomplicated. A brief review of literature is also provided in this paper.
牙齿或牙碎片的医源性移位是拔牙过程中一种罕见但已被充分认识的并发症。下颌第三磨牙碎片最常见的移位部位是舌下、颌下、翼下颌和咽旁间隙。由于视野不佳和操作空间有限，从这些间隙取出移位的牙齿可能很复杂。应通过临床和影像学手段对所有重要危险因素进行全面评估，并精确确定牙齿位置，以预防不良并发症。本文报告了两例下颌第三磨牙医源性移位至舌下间隙和舌袋的病例。两例均在全身麻醉下经口处理，术后愈合良好，未出现并发症。本文还对相关文献进行了简要综述。
