Abstract: Objective To systematically evaluate the accuracy of robotic system-assisted dental implant surgery . Methods A search was performed for studies on surgical robot-assisted implantation, including in vitro model tests, animal experiments, and clinical studies that were published before January 2023, from the databases including PubMed, Embase, Cochrane library, CNKI, VIP, Wanfang and CBM databases. The main outcome index was the deviation between the preoperative design of the implant and the actual position in the three-dimensional direction, including the implant platform, the implant apex and the implant axial angle. Data were combined and analyzed using Stata 17.0. The subgroup analysis was used to compare the deviations of different research designs, with or without implant placement, and different robot systems. Results A total of 14 papers were included, including 9 model trials, 3 clinical studies and 3 animal studies, with a total of 705 implant sites. According to the results of meta-analysis, the deviation of the platform in the robot-assisted implant surgery is 0.72mm (95%CI:0.63-0.81, I²=93.2%), the apex deviation is 0.90mm (95%CI:0.76-1.03, I²=95.7%), and the angle deviation is 1.57° (95%CI:1.26-1.88, I²=98.1%). Conclusion The accuracy of implant surgery robot has reached an acceptable clinical level. Most studies are model trials, and more clinical studies are needed to enrich the data.
