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