摘要
目的:利用锥形束CT对上前牙区埋伏多生牙进行定位分析,并评价其临床应用价值。方法:对门诊常规X线检查难以准确定位的58例上前牙区埋伏多生牙患者行CBCT扫描,三维重建,对埋伏多生牙行定位分析,确定手术进路,指导临床手术。结果:CBCT精确定位58例患者73颗上前牙区埋伏多生牙,清晰直观得显示了多生牙的数目、位置、形态、与周围解剖结构毗邻关系,根据CBCT信息制订手术方案,患者均顺利拔除多生牙。结论:锥形束CT可以准确定位埋伏多生牙,利于术中发现多生牙,减少手术对邻近软硬组织的损伤。
Objective Using CBCT to locate and analyze the embedded supernumerary teeth in the anterior maxillary region,and evaluating the clinical value of CBCT. Methods 58 cases,whose embedded supernumerary teeth in the anterior maxillary region were detected by conventional X-ray examination,but difficult to accurately locate,were examined by CBCT scanning. Three-dimensional images were obtained for localization analysis. According to the CBCT information,we determined the surgical approach,and guided the clinical operation. Results 58 cases who had 73 embedded supernumerary teeth were examind by CBCT scanning. CBCT clearly demonstrated the number,labial or palatal location, morphology, and the surrounding anatomical structures of the embedded supernumerary teeth. With the guiding of CBCT, all embedded supernumerary teeth were successfully removed. Conlusion CBCT can accurately locate the embedded supernumerary teeth in anterior maxillary,guide operation and reduce surgical damage to the adjacent hard and soft tissue.
