摘　　要：目的:探讨不同骨倾角对口腔种植机器人种植手术精度的影响。方法:设计了3种骨倾角模型(分别为45°组、60°组、90°组),采用锥形束计算机断层扫描(cone beam computed tomography,CBCT)对模型进行扫描,并将数据导入机器人系统中进行种植规划。在机器人引导下,分别在3种骨倾角下共植入90枚种植体。术后通过CBCT扫描比较术前规划与实际植入位置的偏差。主要测量指标为种植体植入点、根尖点和角度的总偏差。结果:在45°组、60°组和90°组中种植体植入点总偏差分别为(0.52±0.15)、(0.36±0.13)和(0.34±0.15)mm,根尖点总偏差分别为(0.64±0.19)、[0.46(0.42,0.55)]和(0.37±0.15)mm,角度总偏差分别为(1.27±0.22)°、(1.09±0.21)°和(0.48±0.22)°,且均存在显著统计学差异(P<0.05);在种植体植入点横向和深度偏差、根尖点横向和深度偏差也均存在统计学意义(P<0.05)。结论:口腔种植机器人在3种骨倾角下均能实现较高的种植精度,达到良好的临床效果,但不同骨倾角之间的种植精度存在一定差异。Objective:To investigate the effect of different bone inclinations on the accuracy of dental implant robot.Methods:Three kinds of bone inclination models(45°,60°,and 90°)were designed.The models were scanned by cone beam computed tomography(CBCT),and the data were imported into the robot system for implant planning.Under the guidance of the robot,a total of 90 implants were implanted at three bone inclinations.The deviation between preoperative implant and actual implantation position was compared by CBCT scan after operation.The main measurement indexes were implant angle deviation,and total deviation of entry and apex.Results:In the 45°,60°,and 90°groups,the entry deviations were(0.52±0.15)mm,(0.36±0.13)mm,and(0.34±0.15)mm,respectively,the apical deviations were(0.64±0.19)mm,[0.46(0.42,0.55)]mm,and(0.37±0.15)mm,respectively,and the angle deviations were(1.27±0.22)°,(1.09±0.21)°,and(0.48±0.22)°,respectively(P<0.05).There were also statistically significant differences in the entry level and depth deviations and the apical level and depth deviations of the apical point(P<0.05).Conclusion:The dental implant robotic system achieved high implant accuracy at all three bone inclinations,demonstrating good clinical outcomes.However,there were differences in accuracy between different bone inclinations.
