Introduction: Dental students invest many hours in manual dexterity training to prepare themselves for the clinics. Exercising on plastic has the advantage of learning within a standardized environment; continuing exercises on prefab teeth are unrealistic as plastic does not generate a training facility for clinical problem solving. Introducing a virtual learning environment with haptics and 3D models with realistic pathology (the Simodont) enables students to become competent before they enter clinics, assuming that the competences are easily transferred from virtual reality to reality. Therefore a study has been carried out to investigate if skills developed in virtual reality are transferred to reality. Methodology: Twenty-eight students participated in the study; 10 trained in the traditional phantom lab, 10 trained in the Simodont lab and 8 acted as a control group. Performance was tested before, during and after training. Result: It turned out that all students performed better after little or more training, independent of the training environment. Conclusion: Skills developed in virtual reality on the Simodont were transferred to reality.

To answer drawbacks associated with preclinical training on plastic teeth and extracted human teeth ACTA embarked on a quest towards a virtual clinical lab. In collaboration with Moog Inc. an innovative haptic dental training simulator, the Simodont, was developed to improve the methodology of dental education. The simulator utilizes a virtual reality setting allowing students to practice manual dexterity skills. The operation of Simodont is conducted with courseware, providing the educational context of the training. Simodont offers several significant advantages for learning dental procedures. To integrate theory and practice and to place the exercises within a clinical context, virtual patients are presented to the students. Using a virtual patient authoring system teachers are able to easily distribute virtual patients. Further research on the benefits and feasibility of compliance with the MedBiquitous Virtual Patient specification will be done. To conclude, some success factors in educational virtual reality projects are identified.
