The outcome, should not result in an occlusal interference, nor should it lead to generation of, excessive force on the teeth, the periodontal apparatus or the, should work in harmony and accommodate the changes in occlusal morphology. /Subtype /Image >> Accordingly, when the mandible moves to one side, the overlap of, canines results in separation (disclusion) of posterior teeth on the working, the vertical and horizontal overlap relationships of the canines should be, enough to disclude all other teeth. When the radius, of the curve is long (less concave/less acute), the occlusal plane is flatter than.
