Predicted forces expressed in time. They include bolus, working-side bite point (tooth), working-side (WSJ) and balancing-side temporomandibular joint (BSJ) forces. The lowest curve is the corresponding incisor point motion in the vertical dimension. FO, start of fast opening; MO, maximum jaw opening; B, onset of bolus crush; IC, onset of tooth-to-tooth contact in intercuspation; O, onset of jaw opening.
