title: Trajectories of condylar points during working-side excursive movements of the mandible.
abstract: BACKGROUND
  Trajectories of different condylar points provide different interpretations of condylar movement during open-close jaw movements. Movement of the working-side condyle is often assessed clinically by recording the trajectory of a single arbitrary condylar point.
  
  
  OBJECTIVE
  This study examined the effect of the differences in condylar point location on condylar point movement trajectories during a working-side movement.
  
  
  METHODS
  Different points exhibited different trajectories during a single working-side movement in each of 44 subjects.
  
  
  RESULTS
  Up to 40% of a point's displacement could be attributed simply to the location of the point.
  
  
  CONCLUSIONS
  Interpretation of condylar movement on the working side within a subject depends on the point chosen.
