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.

centric relation

the position of the mandible in relation to the maxilla in which the mandible is positioned midline with the mandibular condyles as posterior and superior as possible within the mandibular fossa. This position is used to determine occlusal relations and positioning for the fabrication of denture prosthetics.

(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.

Therefore, this study investigated the effect of the Lucia Jig in the masticatory muscles of individuals with muscular temporomandibular dysfunction, over the time period of 30 min, with the purpose of evaluating if reprogramming of proprioceptive memory occurs, in order to establish and facilitate obtaining the centric relation, to allow the centralized position of the condyles along with their respective articular discs inside of the articular fossa, to assist in the occlusal adjustment, and to direct the thickness of the myorelaxant occlusal splint.
