Impact Of Surgeon Experience On Mr-Guided Dental Implant Training

A novel mixed reality (MR)-guided dental implant training system was developed and evaluated for its learning effect of this method in novices. We designed and developed a MR based training method that provides real-time supervision, real-time teaching, and real-time guidance. Thirty novices who had passed a baseline test and had no prior experience with implant surgery were randomly divided into two groups: the MR Group (n=15) was trained using the MR training method, while the traditional group (n=15) was received training using conventional methods. Each group involved the following steps: (I) pretest; (II) immediate post-test; (III) implantology training and (IV) retention test. Implant deviations, including platform points, middle points, apex points and axial angles, were measured. Subsequently, learning curves were analyzed, and the usability of the system was evaluated using the System Usability Scale (SUS). After training with the two methods, the deviation of the MR group was significantly lower than that of the traditional group. Learning curve results showed better learning time and effect for the MR group (Y = -95.62X + 1499) compared to the traditional group (Y = -77.36X + 1367). The MR group also had significantly higher SUS scores (80.83 ± 4.880) than the traditional group (69.50 ± 5.362) (P<0.0001). This MR-guided dental implant training method can significantly enhance the learning effect of novices, which offering a novel perspective and strategy for developing personalized and efficient implant placement teaching methods.
