Figure 2. The superimposed sagittal movement traces of the kinematic centers of the left and right joints, and the superimposed frontal movement traces of the lower incisal point of two participants chewing on the right (A) and left sides (B), respectively. For both participants, the contralateral condylar traces were longer and showed a coincident movement pattern. The movement traces on the ipsilateral side showed a non-coincident movement pattern for one participant (A), while for the other participant (B), the joint compression close to the intercuspal position shifted the closing traces so far upward that they were situated even slightly above the opening traces (scored as "coincident pattern"; see also DISCUSSION). The opening traces are gray, closing traces are black.
