| hyperfunctional occlusion | Occlusal stress of tooth or teeth exceeding normal physiologic demands. (05 Mar 2000) |
|---|---|
| spherical form of occlusion | An arrangement of teeth which places their occlusal surfaces on the surface of an imaginary sphere (usually 8 inches in diameter) with its centre above the level of the teeth. See: Monson curve. (05 Mar 2000) |
| neutral occlusion | An arrangement of teeth such that the maxillary and mandibular first permanent molars are in normal anteroposterior relation. Synonym: normal occlusion. Synonym: neutroclusion. (05 Mar 2000) |
| normal occlusion | That arrangement of teeth and their supporting structure which is usually found in health and which approaches an ideal or standard arrangement. Synonym: normal bite. Synonym: neutral occlusion. (05 Mar 2000) |
| dental occlusion | The relationship of all the components of the masticatory system in normal function. It has special reference to the position and contact of the maxillary and mandibular teeth for the highest efficiency during the excursive movements of the jaw that are essential for mastication. (12 Dec 1998) |
| dental occlusion, balanced | Dental occlusion in which the occlusal contact of the teeth on the working side of the jaw is accompanied by the harmonious contact of the teeth on the opposite (balancing) side. (12 Dec 1998) |
| dental occlusion, traumatic | An occlusion resulting in overstrain and injury to teeth, periodontal tissue, or other oral structures. (12 Dec 1998) |
| distal occlusion | A tooth occluding in a position distal to normal. Synonym: disto-occlusion, postnormal occlusion, retrusive occlusion. Synonym: distoclusion. (05 Mar 2000) |
| disto-occlusion | A tooth occluding in a position distal to normal. Synonym: disto-occlusion, postnormal occlusion, retrusive occlusion. Synonym: distoclusion. (05 Mar 2000) |
| occlusion | 1. The act of closure or state of being closed. 2. The relationship between all of the components of the masticatory system in normal function, dysfunction and parafunction. 3. Momentary complete closure of some area in the vocal tract, causing stoppage of the breath and accumulation of pressure. Origin: L. Occlusio (18 Nov 1997) |
| occlusion of pupil | The presence of an opaque membrane closing the pupillary area. (05 Mar 2000) |
| occlusion rim | Occluding surfaces built on temporary or permanent denture bases for the purpose of making maxillomandibular relation records and for arranging teeth. Synonym: bite rim, occlusal rim, record rim. (05 Mar 2000) |
| eccentric occlusion | Any occlusion other than centric. (05 Mar 2000) |
| edge-to-edge occlusion | An occlusion in which the anterior teeth of both jaws meet along their incisal edges when the teeth are in centric occlusion. Synonym: edge-to-edge bite, end-to-end bite, end-to-end occlusion. (05 Mar 2000) |
| torsive occlusion | A malposition of a tooth in which it is rotated on its long axis. Synonym: torsive occlusion, torsoclusion. (05 Mar 2000) |
