自由手、动态导航和机器人辅助种植的精度比较OA

Objective To investigate the differences in precision among various techniques in implant surgery by comparing the accuracy of freehand,dynamic navigation-assisted,and robot-assisted implant placement.Methods Patients who underwent implant surgery at Zhejiang Provincial People's Hospital between January 2022 and December 2023 were retrospectively analyzed and divided into freehand,dynamic navigation,and robotic groups.Implant accuracy was assessed by comparing preoperative CBCT-designed implant positions with actual postoperative CBCT implant positions.Results A total of 87 cases(96 implants)were included in this study,including 30 cases(31 implants)in the freehand group,28 cases(36 implants)in the dynamic navigation group,and 29 cases(29 implants)in the robot group.In the robot group,the total deviation at the starting point(0.91±0.46)mm,endpoint(1.05±0.61)mm,and angular deviation(3.07°±1.69°)were significantly lower than those in the freehand group[(1.42±0.86)mm,(2.00±1.18)mm,and 7.78°±3.58°]and the dynamic navigation group[(1.32±0.57)mm,(1.64±0.77)mm,and 4.59°±2.65°].Conclusion Robot-assisted implantation demonstrates significant advantages in terms of precision when compared to dynamic navigation and freehand implantation.
