Objective To establish a three-dimensional computer-assisted dental model analysis and measurement system and applied to clinical. Methods The video measurement technology was applied to the field of stomatology. The system consisted of coordinate control field, two CCD color cameras, true color image card, high-definition color monitor and computer and other devices. The model measurement and analysis . Results The system was tested to meet the clinical accuracy requirements, and the application of the system were normal occlusion, Class Ⅱ division 1 malocclusion and malocclusion Class Ⅲ malocclusion model were studied. Conclusion The model video stereo measurement system is a set of clinical diagnostic value and promotion of computer diagnostic system
