Figure 6. The relative force output at the upper canine [(I(Tf(cos Q))/Oca) where I, inlever moment arm; Tf, theoretical force output from the muscle fibre; Q, angle between the effective (rotational) torque about the temporomandibular joint and T; O, outlever moment arm to the centre of C1] at gape angles from occlusion to maximal inferred gape in: A, f ca temporalis fibre 1; B, temporalis fibre 3; C, temporalis fibre 5; D, temporalis fibre 7; E, temporalis fibre 8; F, temporalis fibre 10. Negative values imply that an adductor has shifted to becoming an abductor at this gape angle.
