Accuracy of robot and template systems in implant cases: A retrospective non-randomized controlled study

This clinical study aimed to compare the accuracy of implant placement obtained using a robotic system and a full-guide template in patients with dentition defects.

A total of 188 implants were placed in 130 patients with dentition defects. Among them, 94 implants were placed in 56 patients using the robotic system, and 94 implants were placed in 74 patients using the full-guide template. Deviations between ideal and actual implants were calculated postoperatively. The Mann-Whitney U test was used to compare the accuracy between the two groups.

Evaluation of the 94 implants in the r-CAIS group demonstrated an average 3D platform deviation of 0.52(0.27) mm (95 % confidence interval [CI]. 0.49-0.60), 3D apex deviation of 0.57(0.36) mm (95 % CI 0.58-0.69), and 3D angle deviation of 1.47(1.16) ° (95 % CI 1.40-1.76). Evaluation of 94 implants in the s-CAIS group exhibited an average 3D platform deviation of 0.90(0.73) mm (95 % CI 0.91-1.16), 3D apex deviation of 1.33(0.85) mm (95 % CI 1.24-1.53), and 3D angle deviation of 3.41(3.54) ° (95 % CI 3.22-4.07). Significant differences in accuracy were noted between the two groups (p < 0.05).

The implant accuracy of the robotic system was significantly higher than that of the full-guide template in patients with dentition defects.

Implant robotic systems have undergone further functional upgrades based on template and dynamic navigation systems. Research indicates that in routine simple implant cases, the robotic system demonstrates stable and reliable implant placement accuracy. When clinical conditions permit, the robotic system can be preferred over the template system.
