摘　　要：目的评价颌骨牙列体层摄片在埋伏阻生牙定位中的价值。材料与方法使用离体牙在干颅模拟临床常见埋伏阻生牙类型,进行全景片及颌骨牙体断层摄片,观测离体牙在不同位置与其体层片影像的关系。结果颌骨牙列体层摄片能提供直观的埋伏阻生牙在颌骨内位置的二维影像,包括阻生牙的形态,唇侧或腭侧位置,萌出方向及与邻牙的关系。结论对于埋伏阻生牙的放射影像学定位,可选择颌骨牙列体层摄片,临床可以作为骨内埋伏阻生牙外科处理和正畸治疗前的检查手段。Objective To evaluate the value of orthopantomographic imaging in diagnosis of impacted tooth. Materials and methods A dry skull was used to simulate different impacted tooth types. Orthopantomograms were taken to investigate the relation between impacted tooth positions and the images. Results Orthopantomograms provided clear and intuitive 2D impacted tooth image including shape, position, eruption direction and relation to proximal tooth. Conclusions Orthopantomographic imaging technique is a useful way to localize impacted tooth, which is available before oral surgery and to orthodontic treatment planning.
