The accuracy of dental implant placement with different computer-assisted implant surgery techniques

Despite technological advances, achieving ideal three-dimensional precision in dental implant placement remains challenging, with deviations potentially affecting prosthetic outcomes and peri-implant health. Therefore, it is of interest to evaluate the accuracy of static computer-guided, dynamic computer-guided and conventional freehand implant placement techniques. Hence, a total of 120 implants were placed in 96 patients, with at least 40 implants per group and postoperative CBCT images were compared with preoperative plans to measure positional deviations. Both computer-guided approaches demonstrated significantly higher placement accuracy than the freehand method (p < 0.05). Dynamic navigation achieved the best accuracy with minimal coronal (0.71 ± 0.34 mm) and angular (2.18 ± 1.12°C) deviations, indicating its slight advantage in clinical predictability over static guidance.
