It is defined as, "The maxillo-mandibular relationship in which the condyles articulate with the thinnest avascular portion of their respective discs with the complex in the anterior-superior position against the slopes of the articular eminences.
This position is clinically discernible when the mandible is directed superiorly and anteriorly.
It is restricted to a purely rotary movement about the transverse horizontal axis".
This position is used when restoring edentulous patients with removable or either implant-supported hybrid or fixed prostheses.
A properly aligned condyle-disc assembly in centric relation can resist maximum loading by the elevator muscles with no sign of discomfort.
