Movement trajectories of the incisor, molars and condyles on the working and balancing sides from the lateral view. The range of activities of the digastric muscle is plotted along the curvature of a typical movement orbit of each analyzed point in gray, and those of masseter muscles on the working side and balancing side in red and orange, respectively. Each small dot on the movement trajectories represents the position of an analyzed point for each frame of motion capture data. Thirty dots were plotted along the path of one chewing cycle with an interval of 5 ms
