A 12-year-old boy was referred by his orthodontist due to the dysmorphic condition of the impacted teeth 18 and 28. Because teeth 17 and 27 were close related to the third molars, the decision was made to remove the impacted teeth under general anaesthesia. During luxation of tooth 28, it was accidentally displaced deeper into the socket. The tooth could still not be localized after the use of radiographs, an antrostomy, and surgical exploration. It was decided to leave the 28 in its place and to perform cone beam computertomography. This showed that tooth 28 was displaced into the infratemporal fossa. Since the patient was free of symptoms, a period of watchful waiting was initiated. A control visit and cone beam computertomography 9 months postoperatively revealed no signs or symptoms or changes in the position of the displaced tooth. It was therefore decided to leave the third molar in its displaced position. Displacement of a maxillary third molar into the infratemporal fossa is considered a rare complication.
一名12岁男孩因18和28号阻生牙的畸形状况被正畸医生转诊。由于17和27号牙与第三磨牙关系密切，决定在全身麻醉下拔除阻生牙。在拔除28号牙时，它意外地更深地移位到牙槽窝内。在使用X光片、上颌窦开窗术和手术探查后，仍无法确定该牙的位置。决定让28号牙留在原位，并进行锥形束计算机断层扫描。结果显示28号牙移位到了颞下窝。由于患者没有症状，于是开始了一段观察等待期。术后9个月的复诊和锥形束计算机断层扫描显示，移位牙没有出现任何体征、症状或位置变化。因此决定让第三磨牙留在移位后的位置。上颌第三磨牙移位到颞下窝被认为是一种罕见的并发症。
