摘要
目的:探讨采用64排CT进行缺牙区颌骨精细扫描指导医生术前设计和术后评估。方法:利用我院放射科64排CT对种植牙患者行术前术后扫描,将获得的数据信息进行多平面图象重建。结果:通过软件分析10例患者术前术后CT扫描数据,进行多平面图象重建,骨量,密度分析,能清晰地显示出种植区颌骨及邻近组织的解剖结构,及术后种植体三维空间位置.讨论:螺旋CT三维成像及多平面重建辅助术前设计可以有效地控制种植体植入的位置,深度和角度方向,可以有效避免侧壁侧壁穿孔或损伤重要的解剖结构,制定更加周密详尽的手术计划,适当改变种植体位置及角度以获取足够的骨量.及时发现骨内异常钙化点及变异血管,预测种植难度及可能出现的风险.术后CT可以从冠状位,失状位,水平位三个方向分析种植体空间位置,与邻近组织关系,植骨区的情况等。结论:利用CT技术辅助临床种植牙手术及术后评估有重要的临床意义。
Objective:To evaluate the effect of the application of CT scanning in the presurgical plan and postsurgical analysis of dental implant.Methods:Thin-slice scanning of spiral computed tomography was applied to exame the jaw.Sanning data was transmitted to CT digital workstation for analyzing with reconstruction software.Results:10 dental implant cases' presurgical plan and postsurgical analysis gave several different position morphology precisely.Discussion:CT scanning result can guid doctor to drill precisely and safely before implant operation.Then it also can show you the position of implant with three different angle.Conclusion:The technique of CT scanning can guide doctor before operation and test the result after operation.
