Comparative accuracy analysis of robotic and static guided implant surgery: a retrospective clinical study

OBJECTIVE: This study aimed to evaluate the accuracy of robot-assisted implantation by comparing it with guide-assisted implantation in different surgical contexts, including immediate implantation, multi-tooth implantation, maxillary sinus lift, and bone defect. METHODS: Patients receiving implantation with static guide-assisted implant procedures or robot-assisted procedures were classified into the guide group (30 patients, 31 implants) and robot group (30 patients, 32 implants), respectively. Pre- and post-operative CBCT scans were processed with software for 3D reconstruction. Deviations between the original plan and actual implant placement at the apical level, cervical level, and implant angulation were projected into mesio-distal and bucco-lingual directions respectively, and were measured for analysis along with depth discrepancy. RESULTS: Comparing with guide group in this study, the robot group enjoyed smaller angular deviations in both bucco-lingual direction (1.289° ± 1.067 vs. 0.483° ± 0.334, P
