Articulators have long been used for analyzing occlusal relationships during mandibular movements. However, a comprehensive evaluation of occlusal relationships can be hindered by the instrument as well as the casts. Recent developments in computer technology avoid these limitations by providing the ability to visualize and analyze occlusion. The process is accomplished by recording occlusal form and mandibular movements optically and then digitizing them for computer use. The computer can generate a visual simulation of the patient's occlusion at any position during mandibular movement, which enables analysis of the articulation from any perspective.
