摘　　要：目的:探讨全景机颌骨侧位曲面断层片在上颌骨埋伏多生牙定位中的应用价值。方法:对25例上颌骨埋伏多生牙患者采用ORTHOPHS全景机行侧位曲面断层片,分析、判断埋伏多生牙的位置,采取不同的手术径路拔除埋伏多生牙。结果:(1)颌骨埋伏多生牙侧位曲面断层定位精确;(2)颌骨侧位曲面断层能显示牙弓与多生牙的关系;(3)颌骨侧位曲面断层片能显示多生牙的牙体及牙根的形态。结论:颌骨侧位曲面断层片对颌骨埋伏多生牙的定位具有重要价值。PURPOSE : To evaluate the value of localizing maxillary impacted supernumerary teeth with lateral sagittal axial panoramic tomographs. METHODS: 25 patients with maxillary impacted supernumerary teeth were examined by using lateral sagittal axial panoramic tomographs before the teeth were extracted with different approaches. RESULTS: Lateral sagittal axial panoramic tomographs could localize the impacted supernumerary teeth exactly and display the shape of crown, root, and the relationship with the alveolar arch. CONCLUSIONS: Lateral sagittal axial panoramic tomograph is valuable in localizing the impacted supernumerary teeth.
