title: [Analysis of mandibular movement and functional classification for malocclusion patients].
abstract: OBJECTIVE
  To classify the paths of mandibular movements of patients with malocclusion.
  
  
  METHODS
  223 patients were examined clinically and mandibular Kinesiograph(MKG) was applied.
  
  
  RESULTS
  Each kind of malocclusion has its corresponding characteristic paths of mandibular movement. The paths of mandibular movements of patients with the same class of malocclusion are similar. It was also found that the mandibular movement was related not only with occlusion but also with jaws, muscles, and joints. Meanwhile, they affect each other.
  
  
  CONCLUSIONS
  Functional malocclusion classification includes functional class I, II, III and IV malocclusion.
