dc.description.abstract Dental students devote several years to the acquisition of sufficient psychomotor skills to prepare them for entry-level dental practice. They usually rely on traditional training methods, for instance, practicing on dental mannequins with plastic teeth or on live patients. After a training session, dental experts assess students’ dental outcomes based on subjective measures. These traditional methods of skill training and assessment, however, have limitations such as the lack of challenging dental cases, limited availability of expert supervision, and the limited level of detail in human expert assessments. In addition, practice on live patients poses ethical concerns. To address these issues, this dissertation presents a dental training system that pro- vides a simulated yet realistic virtual reality (VR) environment with haptic feedback. With this system, dental students are able to practice dental procedures without need for expert supervision and at little or no incremental cost. The system can monitor important features of the procedure, objectively assess the quality of the performed procedure, and provide feedback on the student’s performance. Incorporated with the system is an intelligent training module that allows students to practice dental procedures with varying levels of guidance. Based on a number of human studies, we find that the realism of the graphics and haptics is acceptable for virtual training. We also find that the accuracy of the objective performance assessment and the quality of the system’s training feedback are high. Moreover, students and experts agree that the intelligent training module is a valuable tool for independent training. These positive results are promising and support the applicability of the simulation system as a supplemental training tool for dental surgical skills. en_US
