Therefore, the, prospective restoration with a steep cuspal angle is permissible as the teeth, FIGURE 7: The greater the angle of the articular eminence, the greater the steepness of the, Table 1: Examples of anterior and posterior determinants, The mandible may bodily shift sideways during its lateral movements as.

This represents a, translatory portion of mandibular movement as viewed in a specific body plane, and occurs at a rate or amount that is directly proportional to the forward, progressive) represent the lateral translation movement of the mandible and, have an effect on the occlusal morphology of teeth, and consequently on, It is important to mention that the immediate and progressive side shifts, describe the lateral translation of the mandible towards the working side in, relation to the movement of the non-working condyle. This can be achieved by, customising the incisal guidance and copying the palatal surface of these teeth, in an impression from which the technician can transfer the palatal surface of, the teeth to the restorations, or by using a custom-made incisal guidance, This is defined as the average plane established by the incisal and occlusal.
