Development of a Prototype Hybrid Mixed Reality and Haptic Task Trainer for Temporomandibular Joint Dislocation

This study introduces a novel mixed reality (MR) TMJ dislocation teaching program developed using HoloLens 2 and collaboration with interdisciplinary teams. The program offers an immersive learning experience, enabling individuals to visualize and interact with detailed 3D temporomandibular joint (TMJ) models and practice different reduction techniques repeatedly. Real-time feedback, combining the visual holographic overlay with mechanical resistance in the physical model, supports the learning process. The 3D-printed skull model provided haptic feedback, strengthened the positive response given by the MR model, and reinforced muscle memory. Despite some challenges related to the learning curve and cost, the program shows promise for practicing uncommon, high-anxiety clinical procedures in medical education. Future research directions include comparisons with traditional teaching methods, evaluating long-term skill retention, and exploring MR applications in other clinical procedures. Overall, this project demonstrates the potential of MR technology to advance medical education and skill acquisition.
