To evaluate the accuracy of the Autonomous Dental Implant Robotic System (ADIR) through animal experiments. Nine canine models with bilateral mandibular premolars loss were prepared. Two implants were placed in each side of canine's mandibular edentulous area. On each side, the two implants were completed by ADIR (robot group) and one experienced doctor using digital full-guided plate (guide template group) respectively. After the operation, the deviation between the actual implant position and the planned position was evaluated. The primary stability of the implant was measured, and the results of the robot group and the guide template group were statistically analyzed. ADIR could successfully place implant for missing teeth in animals, and the coronal deviation, apical deviation and angular deviation [()] were 0.269 (0.152) mm, 0.254 (0.218) mm and 0.989° (0.517°) respectively, which were significantly lower than those of guide template group [the coronal deviation, apical deviation and angular deviation were 0.910 (0.872) mm, 1.179 (1.176) mm and 4.209°(5.208°) respectively] (<0.05). Besides, there was no significant difference in the primary stability of the implant between the two groups (>0.05). This study confirmed the accuracy of the ADIR , and laid a foundation for further clinical trials.
通过动物实验评估自主式牙种植机器人系统（ADIR）的准确性。制备了9个双侧下颌前磨牙缺失的犬类模型。在犬类下颌无牙区的每一侧植入两颗种植体。每一侧的两颗种植体分别由ADIR完成植入（机器人组）和由一名经验丰富的医生使用数字化全引导板完成植入（导板模板组）。术后，评估实际种植体位置与计划位置之间的偏差。测量种植体的初期稳定性，并对机器人组和导板模板组的结果进行统计学分析。ADIR能够成功地为动物缺失牙植入种植体，其冠向偏差、根尖向偏差和角度偏差[（）]分别为0.269（0.152）mm、0.254（0.218）mm和0.989°（0.517°），明显低于导板模板组[冠向偏差、根尖向偏差和角度偏差分别为0.910（0.872）mm、1.179（1.176）mm和4.209°（5.208°）]（<0.05）。此外，两组种植体的初期稳定性无显著差异（>0.05）。本研究证实了ADIR的准确性，为进一步的临床试验奠定了基础。
