Third molar eruption is an unpredictable event. Occasionally, mandibular third molars undergo angular changes in young adults. This rotational drift is of unknown etiology, is not predictable and may facilitate the eruption or may make the im-paction worse. A rare case is presented with severe rotational drift of a mesioangularly impacted mandibular third molar.

第三磨牙的萌出是一个不可预测的事件。偶尔，下颌第三磨牙在年轻成年人中会发生角度变化。这种旋转漂移的病因不明，无法预测，可能会促进萌出，也可能会使阻生情况更糟。本文报告一例罕见的近中倾斜阻生下颌第三磨牙严重旋转漂移的病例。
