The relationship of the mandible to the maxilla, independent of tooth contact, when the mandibular condyles are in their most superior and anterior position, resting on the posterior slopes of the articular eminences with the discs properly interposed. Centric relation can also be described as the position of the mandible relative to the maxilla, with the articular disc in place, when the muscles that support the mandible are in their most relaxed state. See also occlusion.
