title: [Clinical research for the treatment of temporomandibular joint injury based on three-dimensional digital technology].
abstract: OBJECTIVE
  To investigate the accurate and individual treatment of temporomandibular joint(TMJ) injury based on 3D digital technology.
  
  
  METHODS
  Maxillo-mandibular model was made using rapid prototyping technology based on the pre-operation 3D CT results. According to the 3D digital measurement results, TMJ concepts were ordered and the prosthesis was used to simulate the replacement surgery on the model. Then the joint replacement surgery was performed afterward.
  
  
  RESULTS
  (1)After total replacement of TMJ, no pain happened and mouth open was not limited. Three months later, the joint position was normal and stable. The month open width was 4 cm. (2)After condyle replacement, primary healing was achieved with complete survival of bone graft. No edema was seen. Symmetric facial appearance was satisfactory.
  
  
  CONCLUSIONS
  Bilateral individual prosthesis for total TMJ or condyle replacement is an ideal method for TMJ injury.
