| 摘 要： | 目的:探讨锥形束CT(CBCT)在治疗上颌前牙区埋伏牙中的临床应用价值。方法:收集我院2009—2010年经普通X线片确定有埋伏牙,但不易具体定位的患者11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、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和发育情况。11例患者共16颗埋伏牙,其中既有埋伏阻生牙又有埋伏多生牙,3例(4颗)为埋伏多生牙,1例有2颗埋伏牙;2例为倒置埋伏,2例为水平埋伏,3例为垂直埋伏,4例为斜位埋伏。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。

| Abstract: | PURPOSE:To investigate the treatment of impacted maxillary teeth with localization via cone-beam computed tomography(CBCT).METHODS: Eleven cases with impacted maxillary teeth on X-ray examination were selected from 2009 to 2010.The impacted maxillary teeth were scanned by CBCT.The three-dimensional images of impacted maxillary teeth were obtained by multiplanar reconstructions(MPR) to determine the location of impacted teeth.RESULTS: CBCT and MPR can demonstrate the morphology and location and growing state... |
