Accuracy of a Novel Robot‐Assisted System and Dynamic Navigation System for Dental Implant Placement: A Clinical Retrospective Study

Abstract

AimThis clinical retrospective study aimed to compare the deviations in single‐tooth implant placement using novel semi‐autonomous robotic‐assisted surgery system (sa‐RASS) and dynamic navigation system (DNS) methods.Materials and MethodsA retrospective analysis of medical records from January to December 2023 was conducted to compare the implantation accuracy of the sa‐RASS and DNS in partially edentulous patients using cone‐beam computed tomography. Platform, apex, and angular deviations were measured and analyzed. The Kolmogorov–Smirnov test was used to check the data distribution, along with t‐tests or Mann–Whitney U‐tests, where appropriate.ResultsFifty‐seven patients (57 implants) were analyzed: 29 (29 implants) in the sa‐RASS group and 28 (28 implants) in the DNS group. The comparison of platform, apex, and angular deviation between the sa‐RASS group and DNS group were 0.91 ± 0.46 mm vs. 1.26 ± 0.51 mm (p < 0.001), 1.06 ± 0.60 mm vs. 1.51 ± 0.56 mm (p < 0.001), and 3.07° ± 1.66° vs. 3.71° ± 1.64° (p > 0.05), respectively. In addition, there was no significant difference in the accuracy of different implant regions (premolar, molar, maxilla, and mandible) or implant length (p > 0.05).ConclusionsIn the present study, sa‐RASS implant placement showed better positional accuracy than DNS implant placement in platform and apex deviation, although these improvements in accuracy may have limited clinical relevance, suggesting that the sa‐RASS might be advantageous in dental implant surgery.Trial Registration: ClinicalTrials.gov identifier: ChiCTR2400085089
