In circumstances exactly where the anterior enamel would Call ahead of reaching the specified range of bilateral balanced occlusion, the vertical overlap of the anterior tooth can be minimized to tactic an incisal steerage of zero. In the two situations, a slight compensating occlusal curve might be required to attain continuous posterior contacts anterior to centric relation.[3]
In left lateral excursive movements, only the maxillary palatal cusps make Make contact with. Selective grinding on the maxillary buccal cusps can be wanted to make a clearance among the maxillary and mandibular buccal cusps [Determine 10].
