【摘要】：目的:通过CT扫描、计算机辅助设计和制造技术获得带有不同定位方式的通用型种植导板精度。方法:采用通用型导板进行种植,然后获取90颗种植体的术后位置数据,并按照黏膜支撑导板和牙支撑导板进行分类,最后将该数据与术前设计数据进行比较,并以种植体颈部、顶部、深度和角度误差进行描述。结果:牙支撑导板的平均颈部偏差为1.56mm,顶部平均偏差1.78mm,深度平均偏差1.1mm,角度平均偏差2.96°;黏膜支撑导板平均颈部偏差1.71mm,平均顶端偏差1.9mm,深度平均深度偏差1.09mm,角度平均偏差3.19°。结论:牙支持导板与黏膜导板相比,牙支持导板精度更高;与专用导板相比通用导板在颈部误差方面要偏大,而在深度、顶端和角度误差方面则没有显著差异。
[Abstract]:Objective: to obtain the accuracy of universal implant guide with different positioning methods by CT scanning, computer aided design and manufacturing technology. Methods: the data of 90 implants were obtained and classified according to mucosal support guide and tooth support guide. Finally, the data were compared with the preoperative design data. The implant neck, top, depth and angle error are described. Results: the average neck deviation, top deviation, depth deviation and angle deviation were 1.56 mm, 1.78 mm, 1.1 mm and 2.96 掳, respectively. The average deviation of the mucosal support guide was 1.71 mm for neck, 1.9 mm for tip, 1.09mm for depth and 3.19 掳for angle. Conclusion: the accuracy of dental support guide is higher than that of mucous membrane guide, and that of general guide plate is larger than that of special guide plate, but there is no significant difference in depth, top and angle error.
