The maximum balanced intercuspation of maxillary and mandibular teeth; may or may not coincide with centric relation. Positional relationship of occluding tooth surfaces when the mandible is in centric relation. The coincidence of centric occlusion and centric relation is desirable when creating an occlusion, but the maximal intercuspal relationship may not always exist.
(Acquired centric and habitual occlusion): The maximum intercuspation or contact of the teeth of the opposing arches.
In dentistry, the vertical and horizontal position of the mandible that produces maximal interdigitation of the cusps of the maxillary and mandibular teeth. This is the ideal position or type of occlusion. It is also described as intercuspal position, tooth-to-tooth position, habitual centric, or acquired centric.
