Robotic surgery in implantology: a comparative accuracy evaluation of the YakeBot system and Dcarer dynamic navigation

Objective. To compare the accuracy of single dental implant placement using the autonomous robotic system YakeBot and the Dcarer dynamic navigation system. Materials and methods. A prospective randomized clinical study of single dental implant placement was conducted from August 2025 to February 2026. The analysis included 40 cases: YakeBot – 20 implants, Dcarer – 20 implants. Each group contained 10 implants in the anterior region and 10 in the posterior region. Coronal, apical, and angular deviations between the preoperative digital plan and the actual implant position based on postoperative cone beam computed tomography (CBCT) were evaluated. Due to non-normal distribution, the Mann–Whitney U test was used; data are presented as median and interquartile range (IQR). Results. In the YakeBot group, coronal deviation was statistically significantly lower than in the Dcarer group: 0.714 (0.609–1.240) mm vs. 1.395 (0.990–2.488) mm; U = 99; p = 0.0066. Apical deviation was also lower: 0.732 (0.573–1.275) mm vs. 1.305 (1.030–2.483) mm; U = 111; p = 0.0167. Angular deviation showed a trend in favor of YakeBot but without statistical significance: 1.266 (0.864–1.624)° vs. 1.575 (0.925–2.495)°; U = 141; p = 0.1135. Conclusions. In a prospective, randomized clinical trial, the YakeBot robotic system demonstrated higher linear accuracy in implant positioning compared to the Dcarer dynamic navigation system. Angular deviation showed a non-significant trend in favor of the robotic system. These findings require confirmation in prospective studies with independent outcome assessment.
