Intrabony migration of impacted teeth is a rare dental anomaly, which occurs only in the permanent dentition of the lower jaw. The teeth involved in this phenomenon are the mandibular lateral incisor, canine, and second premolar. Migration of the lateral incisor is usually in a distal direction, resulting in transposition with the canine. Migration of the canine is most frequently in a mesial direction, resulting in transmigration across the mandibular symphysis to the opposite side of the dental arch. The second premolar most often migrates distally, sometimes past the gonial angle and as far as the coronoid process. Surgical and orthodontic treatment options are presented for the three intrabony migrating teeth.
阻生牙的骨内移位是一种罕见的牙颌异常，仅发生在下颌恒牙列。参与此现象的牙齿是下颌侧切牙、尖牙和第二前磨牙。侧切牙的移位通常是向远中方向，导致与尖牙换位。尖牙的移位最常是向近中方向，导致穿过下颌联合向牙弓的对侧移位。第二前磨牙最常向远中移位，有时会越过下颌角直至冠状突。本文介绍了针对三种骨内移位牙齿的手术和正畸治疗方案。
