Transmigration of impacted mandibular cuspid is a rare finding. A cuspid is classified as "transmigrated" when more than half of its length has passed the mid-line. 13 cases of transmigration of impacted mandibular cuspids are presented, 3 of which occurred in pairs, raising the total number of teeth to 16. Radiographs showed positions ranging from a vertical impaction, to a cuspid having crossed the mid-line completely, reaching the first molar area of the opposite side.
阻生下颌尖牙异位萌出是一种罕见的情况。当尖牙长度超过一半越过中线时，该尖牙被归类为“异位萌出”。本文报告了13例阻生下颌尖牙异位萌出病例，其中3例为双侧发生，使牙齿总数达到16颗。X线片显示其位置从垂直阻生到尖牙完全越过中线，到达对侧第一磨牙区不等。
