Animal experiment on the accuracy of the Autonomous Dental Implant Robotic System].

Objective: To evaluate the accuracy of the Autonomous Dental Implant Robotic System (ADIR) in vivo through animal experiments. Methods: 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. Results: ADIR could successfully place implant for missing teeth in animals, and the coronal deviation, apical deviation and angular deviation [M(Q)] 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] (P<0.05). Besides, there was no significant difference in the primary stability of the implant between the two groups (P>0.05). Conclusions: This study confirmed the accuracy of the ADIR in vivo, and laid a foundation for further clinical trials.
