Abstract：BACKGROUND:Guidances for design of Chinese people’s temporomandibular joint prosthesis are urgently needed because foreign prosthesis is unsuitable for Chinese people due to variant anatomy parameters. <br> OBJECTIVE:To provide a reference for improving the design of artificial temporomandibular joint through computer three-dimensional digital measures of the anatomy parameters of the temporomandibular joint. METHODS:Continuous CT data with layer thick 0.625 mm of 30 normal temporomandibular joints were selected. Three-dimensional digital reconstruction and eight related anatomy parameter measurements of the articular fossaandcondylar of the joints were performed using Mimics10.01 software. <br> RESULTS AND CONCLUSION:The internal and external diameter of the mandibular fossa, head of mandible and neck of mandible were greater thantheanterior and posteriordiameter. The mandibular foramen was located at middle-posterior of the ramus ofthe mandible. The distance between head of the mandible and coronoid process was longer than the depth of the mandibular notch. There were no <br> significant differences between two sidesregardingal above-mentioned parameters. There are certain regular patterns in anatomy parameters of the temporomandibular joint. The study results wil provide a reference for improving the design of artificial temporomandibular joint.
