(a) The 5 mechanically distinctive orientations of T defined by relative location (ℊ and ℎ, Figure 2(b)) and cusp contact inclination. T 1, T0, and T2 have posteriorly directed horizontal components. T3 is vertical. T4 has an anterior component. T1 produces a ccw moment about the circle. T0 generates no moment. T2, T3, and T4 generate cw moments. (b) A generic representation of Figures 2(b) and 3(a). Note that a change in the anterior-posterior relative location of bite contact and ◯ is defined by ℎ. Occlusal plane height is given by ℊ.
