永久上颌中切牙的阻生是罕见的。上颌乳牙的创伤是最常见的原因。本文报告两例上颌阻生恒中切牙，并有乳牙前牙外伤病史。其中一例有放射学证据显示牙根形成完全停止，另一例牙根从颈部的三分之一开始扩张，牙釉质表面粗糙。
Impaction of the permanent maxillary central incisor is rare. Trauma to the primary maxillary anterior teeth is the most common cause. Two case reports of impacted permanent maxillary central incisors with a history of trauma to the primary maxillary anterior teeth are presented. In one case there was radiographic evidence of complete arrest of root formation, and in the other case the root was dilacerated from the cervical third and the enamel surface was rough.
