摘要/Abstract

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1.56 mm,顶部平均偏差1.78 mm,深度平均偏差1.1 mm,角度平均偏差2.96°;黏膜支撑导板平均颈部偏差1.71 mm,平均顶端偏差1.9 mm,深度平均深度偏差1.09 mm,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 evaluate the accuracy of surgical templates which have different located modes with the aid of CT and computer-aided design and manufacture technology. Methods: Teeth-supported and mucosa-supported templates were used in surgery for 90 implants. The actual and designed implant positions were recorded accordingly. The hex, apex, depth, and angular deviation of implants were analyzed. Results: For teeth supported surgical template, the mean hex deviation, apex deviation, depth deviation, and angular deviation were 1.56mm, 1.78mm, 1.1mm, and 2.96°, respectively. The mean hex deviation, apex deviation, depth deviation, and angular deviation for mucosa supported surgical template were 1.71mm ,1.9mm, 1.09mm, and 3.19°, respectively. Conclusion: Teeth-supported templates are more accuracy than mucosa-supported templates. Compared with specific templates, the commonly-used templates had no significance in depth, hex, and angular deviation.
