For instance, the shape and angle of the articular eminence of the glenoid fossa, affect the movement of the mandible and teeth by the path that the condyles, must travel when the mandible moves. /Resources 72 0 R It also provides a practical guide to what is required to optimise the restorative treatment outcome. /CA 1 >> FIGURE 15: The canine guidance occlusion. 2015-10-21T12:40:39+01:00 ... A FISO is when the prosthesis is permanently fixed to the implants through screw-joints between the prosthesis and the implants. When the radius, of the curve is long (less concave/less acute), the occlusal plane is flatter than. 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.

Canine teeth are suitable to guide the mandible during its excursive movement, for many reasons, as previously mentioned.
