What is the difference between centric relation and centric occlusion?

Centric occlusion refers to a position of maximal, bilateral, balanced contact between the cusps of the maxillary and mandibular arches. Centric relation is the most retruded, unstrained position of the mandibular condyle within the temporomandibular joint (TMJ), that is, within the glenoid fossa.
