The use of haptic devices in the medical field has become widespread in the last decade. In this study, a visio‐haptic dental training system is developed using haptic and stereoscopic devices. Several advantages are offered by such a simulation system, including effective learning without any fear of making mistakes on a patient, possibility of repeating various dental operations, ease of evaluating student performance, and low‐cost dental training even without an instructor. In this study, the biomechanical properties of enamel, dentin, pulp, and caries were modeled, and the parameters were fine‐tuned to provide more realistic haptic sensations. Maxillary and mandibular dental arches and various dental instruments such as mouth mirror, probe, and dental drills were modeled in a 3D virtual environment. Probing and cavity preparation on teeth were implemented in the training system. Various graphical rendering methods (Surface Rendering in CPU, Iso‐Surface Rendering, and Ray‐Casting in GPU) were implemented and compared in performance. The implementation details and the software structure used are described. Finally, detailed performance tests by a group of dentists are conducted, and the results of these tests are presented. The performance tests found that dentists have a strong motivation to use the system and that in the aspects of usability, clarity, effectiveness, help/support provided, and satisfaction, the users’ responses were above average.
