A model for the simulation of temporomandibular joint (TMJ) function was developed by our group based on human TMJ measurements and computer-aided design/computer-aided manufacture (CAD/CAM) as a tool for the visualization of TMJ function. We found that only a few parameters are needed to visualize both temporal bone and condylar surfaces as subregions of rotation bodies. With condyle and temporal bone specimens, we found that it was possible to match practically all points of interest, vary the condylar axes to simulate all types of functional movement, and produce near-natural models of the TMJ discs as well as pathological variations using the developed model. It proved to be a good visualization tool suitable for teaching purposes. It can also be used for the comparison and analysis of various functional scenarios in scientific research. The model can be used to study TMJ disc function and variation, rotation, displacement and torsion, and the results can be analyzed in relation to magnetic resonance imaging (MRI) findings and pathological manifestations.
