Mutually protected occlusion
In dentistry, a mutually protected occlusion is an occlusal scheme in which the anterior teeth protect the posterior teeth, and vice versa. The anterior teeth protect the posterior teeth by providing for a plane of guidance during excursions, thus allowing the cusps of the posterior teeth to disclude rather than strike one another during lateral or protrusive movements from centric relation.
