-translation: a sliding or gliding motion.
-Christensen’s phenomenon: space between posterior teeth during protrusion or on the balancing side during lateral excursions.
-mandibular lateral translation: translatory portions of lateral excursions described as immediate or progressive.
-Bennett movement: OBSOLETE TERM.
-Bennett angle: angle formed by the sagittal plane and the path of the advancing condyle during lateral mandibular movements as viewed in the horizontal plane.
-Fisher angle: angle formed by the inclinations of the protrusive and non-working side condylar paths as viewed in the sagittal plane.
-centric relation: condyles in the most anterior-superior position against the slopes of the articulator eminences, regardless of any tooth relationships.
-centric relation contact: position of the mandible on the centric relation arc of closure when the teeth first contact.
-centric occlusion: occlusion of opposing teeth when the mandible is in centric relation.
-maximum intercuspation: maximum occlusal contact or intercuspation irrespective of condylar position.
-physiologic rest position: position of mandible when the head is in the upright position, the elevator and depressor muscles are in equilibrium in tonic contraction
-interocclusal rest space: difference between the physiologic rest position and the vertical dimension of occlusion.
-parafunction: abnormal function of the masticatory system (bruxism or clenching).
-mutual protection: when anterior teeth protect the posterior teeth during excursive contacts.
-unilateral balanced articulation: when posterior teeth on the working side contact as a group simultaneously with contact on the anterior guidance.
-bilaterally balanced articulation: group contact between posterior teeth simultaneously with contact on the anterior guidance in both working and balancing excursions.
-axial loading: when occlusal forces align along the vertical axes of the teeth.
-anterior guidance: anterior determinant of mandibular movement.
-condylar guidance: the posterior determinant of mandibular movement.
-stamp (functional) cusp: centric holding cusp. Buccal on the mandible; lingual on the max.
-shear (non-functional) cusp: lingual on the mandible; buccal on the max.
-working side interference: interference between posterior teeth on the side of the dental arches to which the mandible is moving laterally.
-non-working side interference: interference between posterior teeth on the side of the dental arches away from which the mandible is moving.
-protrusive interference: interference between posterior teeth on either side of the dental arches caused by a protrusive movement.
-lateral protrusive interference: an interference involving exclusively the maxillary lateral incisor against its opponent during excursion of the mandible.
-crossover interference: interference between posterior teeth when the mandible translated laterally beyond the guidance of the cusps.
-apexification: externally loading the condyles in centric relation.
-primary occlusal traumatism: perio tissue changes induced by occlusal forces in excess of normal masticatory function.
-secondary occlusal traumatism: perio tissue changes induced by occlusal forces produced by normal masticatory function on teeth with decreased attachment apparatus.
-fremitus: vibration of the roots of teeth that close into contact.
-engram: memorized pattern of muscle activity.
-crepitus: a crackling or grating noise in a joint during movement.
