目的：探讨锥形束CT（CBCT）在上颌前牙区埋伏牙定位中的临床应用价值。方法收集广州医学院口腔医院2011-2012年经普通曲面断层片确定有埋伏牙，但不能具体定位的患者23例，进行CBCT 扫描和三维重建，确定埋伏牙在颌骨内的具体位置。结果经CBCT 扫描和三维重建后，所有患者均可直观再现埋伏牙的形态、数目、在颌骨中的具体位置。根据CBCT 结果制订治疗方案，获得满意的治疗效果。结论 CBCT 三维重建对于上颌前牙区埋伏牙治疗方案的设计及实施具有重要意义。

Objective To investigate the treatment of impacted maxil ary teeth with cone-beam computed tomography (CBCT).Methods Twenty three cases were col ected in our hospital from 2011 to 2013. they had Maxil ary impacted teeth on the panoramic radiographs which could not provide accurate position.The Maxil ary impacted teeth were scanned by CBCT.The three-dimensional images of Maxil ary impacted teeth were obtained by multiplanar reconstructions to determine the specific location .In the maxil ary.Results The morphology, the number ,the specific location and spital relationship with adjacent structures of the Maxil ary impacted teeth could be showed by CBCT scanning and multiplanar reconstructions .The study.made treatment plan according to the results of CBCT,and obtain satisfactory curative effect.Conclusion It is important to resign and implement treatment for impacted teeth in maxil ary anterior region by using CBCT and multiplanar reconstructions.
