N2 - A Multiple Simulation System can provide useful insight to clinical diagnosis and treatment. However, when metal prostheses are present in the patient, the quality of the CT is greatly reduced, resulting in an image that is distorted and thus provides little understanding on extraction and form of dentition. In order to circumvent this, we scanned the surface of a plaster dental model with a 3-D scanner. Subsequently, this model was digitally combined with the CT reconstruction model, and used as a guide to remove any disturbances that were due to the presence of metal artifacts. The VR and physical occlusal contacts were accorded about 55%. Subsequently, we were able to reproduce a skull model specific to the patient occlusal contacts. This was verified via color mapping. In addition, this system was able to provide a quantitative clinical and dental evaluation of the teeth adjustment configuration.
