| centric jaw relation | 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 which can exist at various degrees of jaw separation, and it occurs around the terminal hinge axis, the most posterior relation of the mandible to the maxillae at the established vertical relation See: eccentric relation. Synonym: median retruded relation, median relation. (05 Mar 2000) |

| acquired centric relation | See: centric jaw relation. (05 Mar 2000) |
|---|---|
| centric relation | The location of the maxillary and the mandibular condyles when they are in their most posterior and superior positions in their fossae of the temporomandibular joint. (12 Dec 1998) |
| occluding centric relation record | A registration of centric relation made at the established occlusal vertical dimension. (05 Mar 2000) |
| rest jaw relation | The postural relation of the mandible to the maxillae when the patient is resting comfortably in the upright position and the condyles are in a neutral unstrained position in the glenoid fossa. Synonym: rest jaw relation, unstrained jaw relation. (05 Mar 2000) |
| protrusive jaw relation | A jaw relation resulting from a protrusion of the mandible. (05 Mar 2000) |
| terminal jaw relation record | A record of the relationship of the mandible to the maxillae made at the vertical relation of occlusion and at the centric position. (05 Mar 2000) |
| jaw relation record | A registration of any positional relationship of the mandible in reference to the maxillae. These records may be any of the many vertical, horizontal, or orientation relations. (12 Dec 1998) |
| unstrained jaw relation | The postural relation of the mandible to the maxillae when the patient is resting comfortably in the upright position and the condyles are in a neutral unstrained position in the glenoid fossa. Synonym: rest jaw relation, unstrained jaw relation. (05 Mar 2000) |
| centric | Having a centre (of a specific kind or number) or having a specific thing as its centre (of interest, focus, etc.). Origin: G. Kentron, centre (05 Mar 2000) |
| centric contact | The relation of opposing occlusal surfaces which provides the maximum planned contact and/or intercuspation, the occlusion of the teeth when the mandible is in centric relation to the maxillae. Synonym: centric contact. (05 Mar 2000) |
| centric fusion | <molecular biology> A special type of nonreciprocal translocation in chromosomes whereby the long arms of two nonhomologous acrocentric chromosomes are attached to a single centromere. The short arms become attached to form a reciprocal structure that however often disappears some divisions after its formation. (17 Dec 1997) |
| centric interocclusal record | A record of centric jaw relation, eccentric interocclusal record, a record of jaw position in other than centric relation, lateral interocclusal record, a record of a lateral eccentric jaw position; and (05 Mar 2000) |
| centric occlusion | The relation of opposing occlusal surfaces which provides the maximum planned contact and/or intercuspation, the occlusion of the teeth when the mandible is in centric relation to the maxillae. Synonym: centric contact. (05 Mar 2000) |
| centric position | The position of the mandible in its most retruded unstrained relation to the maxillae. See: centric jaw relation. (05 Mar 2000) |
| acquired eccentric relation | An eccentric relation that is assumed by habit in order to bring the teeth into occlusion. (05 Mar 2000) |
