Intentional coronectomy has become a commonplace procedure as an alternative to full third molar removal in order to decrease the occurrence of inferior alveolar nerve (IAN) injury. It is well known that one of the sequelae of this procedure is superior root migration. This is usually not a significant problem as the migrated roots may erupt to a position where they are more readily removed. This report presents a case in which a curvature at the apex of the root displaced the IAN causing neurologic symptoms.
由于全下颌第三磨牙拔除术可能会导致下牙槽神经（IAN）损伤，因此预防性下颌第三磨牙冠根切除术已成为一种常见的替代方法。众所周知，该手术的一个后遗症是上颌根迁移。通常情况下，这不是一个大问题，因为迁移的牙根可能会萌出到更容易被移除的位置。本报告介绍了一例根尖弯曲的病例，该病例导致 IAN 移位并引起神经症状。
