Objective: To preliminarily evaluate the accuracy of a segmented rotational motion-based osteotomy module for autonomous dental implant robots in immediate placement anterior region through an vitro model experiment, providing references clinical practice. Methods: Twenty-three identical commercial maxillary resin models with dentition defects were divided into three groups: fully guided static computer-assisted surgery (sCAIS) group (n=5), robotic (rCAIS) based on conventional coronal-apical linear motion (rCAIS-C, n=9) and rCAIS (rCAIS-S, n=9). Two implants placed each using corresponding surgical protocols. Intraoral scan data pre-and post-operative imported software to deviations between actual planned positions. Results: In rCAIS-S group, global at platform apex 0.50 (0.32) mm 0.52 (0.22) mm, respectively, angular deviation 1.08° (0.49°). These values significantly smaller than those sCAIS [platform: 0.88 (0.50) apex: 1.44 deviation: 2.86° (1.76°), P<0.05]. also showed compared rCAIS-C 0.69 (0.12) 0.94 (0.16) P<0.05], though did not differ from [1.27° (0.56°), P>0.05]. Conclusions: Within limitation this study, demonstrates superior area osteotomy.
