jaw relation

jaw relation,

any relation of the mandible to the maxilla.

---

jaw,

n a common name for either the maxillae or the mandible; the meaning is usually extended to include their soft tissue covering.

jaw, cleft (gnathouschisis),

n See palate, cleft.

jaw cyst,

n an abnormal bladderlike sac within the jaw. May occur in either the maxilla or mandible associated with or not associated with the dentition and its formation. See also cyst.

jaw, fibro-osseous, lesion,

n See lesion, fibroosseous jaw.

jaw fracture,

n a break in the continuity of the bone of the maxilla or mandible. See also fracture.

jaw, lumpy,

n See actinomycosis.

jaw movement,

n See movement, jaw.

jaw, phossy,

n See poisoning, phosphorus.

jaw reflex,

n See reflex, jaw.

jaw relation,

n See relation, jaw.

jaw-to-jaw relationship,

n See relation, jaw.

relation(s),

n the designation of the position of one object as oriented to another (e.g., centric relation of the mandible to the maxillae).

relation, acentric,

n See relation, jaw, eccentric.

relation, acquired centric,

n See relation, jaw, eccentric, acquired.

relation, acquired eccentric jaw,

n an eccentric relation that is assumed by habit to bring the teeth into a convenient occlusion.

relation, centric,

n (centric jaw relation), the relation of the mandible to the maxillae when the condyles are in their most posterosuperior unstrained positions in the glenoid fossae, from which lateral movements can be made at the occluding vertical relation normal for the individual. Centric relation is a relation that can exist at any degree of jaw separation.

relation, centric jaw,

n See relation, centric.

relation, cusp-fossa,

n See cusp-fossa relations.

relation, dynamic,

n relations of two objects involving the element of relative movement of one object to another (relationship of the mandible to the maxillae).

relation, eccentric,

n See relation, jaw, eccentric.

relation, eccentric jaw,

n (convenience relationship, eccentric relation, eccentric jaw position), any jaw relation other than centric relation.

relation, intermaxillary,

n the relation between the right and left maxilla. See also relation, maxillomandibular.

relation, jaw,

n a relationship of the mandible to the maxillae.

relation, lateral,

n the relation of the mandible to the maxillae when the mandibular arch is in a position on either side of centric relation.

relation, maxillomandibular

n any one of the many relations of the mandible to the maxillae, such as the centric maxillomandibular relation or eccentric maxillomandibular relation.

relation, median,

n See relation, centric.

relation, median jaw,

n a jaw relationship existing when the mandible is in the median sagittal plane.

relation, median retruded,

n See relation, centric.

relation, occluding,

n the jaw relation at which the opposing teeth contact or occlude.

relation, posterior border jaw,

n the most posterior relation of the mandible to the maxillae at any specific vertical dimension.

relation, protrusive

n See relation, jaw, protrusive; position, rest, physiologic.

relation, protrusive jaw,

n (protrusive relation), a jaw relation resulting from a protrusion of the mandible.

relation, rest,

n See position, physiologic rest.

relation, rest jaw,

n (rest), the postural relation of the mandible to the maxillae when the patient is resting comfortably in the upright position, the condyles are in a neutral unstrained position in the glenoid fossae, and the mandibular musculature is in a state of minimum tonic contraction to maintain posture.

relation, ridge,

n the positional relation of the mandibular ridge to the maxillary ridges.

relation, static,

n the relationship between two parts that are not in motion.

relation, unstrained jaw,

n the relation of the mandible to the skull when a state of balanced tonus exists between all the muscles involved.

relation, vertical,

n the relative position of the mandible in a vertical direction; one of the basic jaw relations.
