How various occlusal schemes alter Temporalis clenching intensity
The potential  intensity of the contraction of the temporalis (clenching) is a function of the available occlusal scheme (which can be a function of the position of the mandible during the clenching event).

The maximum contraction intensity is when the teeth slightly apart (thereby a minimal degree of translation), and can exceed greater than voluntary maximum in intercuspal position.  Canine contact through their long axis allows for near maximal intensity, and incisor-only contact allows for minimal intensity.
