中文摘要
磨牙阻生是临床常见的牙颌发育异常，其中以第三磨牙阻生最为多见，而第二磨牙阻生发病率相对较低。本文报道了1例因多颗第二磨牙近中阻生导致相邻第一磨牙牙根外吸收的青少年男性患者。通过正畸治疗与外科手术干预相结合，实现了牙列排齐及咬合功能改善，有效预防了进行性牙根外吸收可能导致的远期并发症的发生。
英文摘要
Tooth impaction is a prevalent dentofacial developmental anomaly, mostly observed in third molars, whereas second molar impaction occurs with lower frequency. This article presents a case of a male adolescent with mesially impacted second molars resulting in the external root resorption of multiple first molars. The patient received orthodontic and surgical treatments simultaneously, achieving dental alignment and enhanced occlusal function. The treatments mitigated the long-term adverse complications of external root resorption.
