centric relation

cen·tric jaw re·la·tion

, centric relation
1. the most retruded physiologic relation of the mandible to the maxillae to and from which the individual can make lateral movements; it is a condition that can exist at various degrees of jaw separation, and it occurs around the terminal hinge axis;
See also: eccentric relation.
2. the most posterior relation of the mandible to the maxillae at the established vertical relation
See also: eccentric relation.

cen·tric re·la·tion

(sen'trik rĕ-lā'shŭn)
The relation of the lower to the upper jaw when the condyles are in their most posterior and superior position in the mandibular (glenoid) fossae.
Synonym(s): terminal hinge position.

One of the incisal tables without disclusion was placed on the articulator so that the tip of the incisal pole contacted the incisal table in centric relation. Two 3mm thick spacers were prepared to approximate the protrusive movement position.
