摘要： 目的: 利用CAD/CAM设计数字化种植导板辅助牙列缺损患者种植修复的方式,对术前、术后种植体三维位置对比,分析不同骨质对牙支持式数字化种植导板精确度的影响,为今后提高数字化种植导板精确性提供理论依据。方法: 依据设定好的纳入及排除标准共纳入患者62例,进行数字化导板辅助下种植手术,将不同骨质种植外科术后种植体位置与术前设计位置进行匹配,并进行统计分析。结果: 研究对象62例,年龄34~74岁,平均(49.6±9.69)岁,62颗种植体测量肩部偏移为(1.38±0.26) mm,根尖部偏移为(1.57±0.24) mm,角度偏移为(1.75±0.62)°,根尖部偏移略大于肩部偏移。(1)Ⅰ级骨质肩部偏移大于Ⅱ、Ⅲ、Ⅳ级骨质(P<0.05)。(2)Ⅰ、Ⅳ级骨质根尖部偏移大于Ⅱ、Ⅲ级骨质(P<0.05)。(3)Ⅰ级骨质角度偏移大于Ⅱ、Ⅲ、Ⅳ级骨质(P<0.05)。结论: 不同骨质对牙支持式数字化种植导板精确性有影响,其中I级骨质在肩部、根尖部、角度偏移方面精确性较低;Ⅳ级骨质在根尖部、角度偏移方面精确度较低,但在肩部精确性较高;Ⅱ、Ⅲ级骨质在肩部、根尖部、角度偏移方面等精确性较高,是数字化种植导板应用效果最佳的骨质。

Abstract: Objective: To analyze the influence of different bone types on the accuracy of digital implant guide. Methods: According to the set inclusion and exclusion criteria, a total of 62 patients were included, the implant surgery assisted by digital guide plate was performed for all patients. The implant position after different bone implant surgery was matched with the preoperative design position. Results: The patients were aged from 34 to 74 years old, with an average of (49.6±9.69) years old. The shoulder offset of 62 implants was (1.38±0.26) mm, the apical offset was (1.57±0.24) mm, the angle offset was (1.75±0.62)°, and the apical offset was slightly larger than shoulder offset. The shoulder deviation of grade I bone was greater than that of grade Ⅱ, Ⅲ, and Ⅳ bone (P<0.05). The apical deviation of grade Ⅰ and Ⅳ bone was greater than that of grade Ⅱ and Ⅲ bone (P<0.05). The angle deviation of grade Ⅰ bone was greater than that of grade Ⅱ, Ⅲ, and Ⅳ bone (P<0.05). Conclusion: The accuracy of dental digital implant guide is affected by different bone types. Grade Ⅱ and Ⅲ bone are the best bone for digital implant guide.
