【摘要】 目的:探讨锥形束CT在埋伏多生牙定位中的应用价值。方法:对39例(42颗多生牙)经常规X线检查无法定位的埋伏多生牙患者做回顾性分析。经锥形束CT扫描,通过三维重建进行观察。结果:锥形束CT能准确定位多生牙的方向、数量及与邻近组织的空间位置关系。结论:锥形束CT可以直观、准确地对埋伏多生牙定位,对临床手术路径的确定、治疗方案的选择有重要应用价值。更多还原

【Abstract】 Objective: To investigate the clinical application of cone-beam computer tomography in impacted supernumerary teeth location.Methods: 39 patients(with 42 supernumerary teeth) who had been examined by conventional X-ray examination with none location result,were scaned by cone-beam computer tomography and observed in three-dimensional reconstruction.Results: Cone-beam computer tomography possessed the advantages in three dimensional location,amount of the supernumerary teeth,and spital relationship with adjacent structures.Conclusion: Cone-beam computer tomography is intuitive and accurate positioning impacted supernumerary teeth,which has an important application value in surgical access option and treatment plan instruction.更多还原
