| unequal retinal image | A condition in which the ocular image of an object as seen by one eye differs in size and shape from that seen by the other. (12 Dec 1998) |
|---|---|
| 11-cis-retinal | The isomer of retinaldehyde that can combine with opsin to form rhodopsin; it is formed from 11-trans-retinal by retinal isomerase. Synonym: neoretinal b. (05 Mar 2000) |
| abnormal occlusion | An arrangement of the teeth which is not considered to be within the normal range of variation. (05 Mar 2000) |
| afunctional occlusion | A malocclusion which does not permit normal function of the dentition. (05 Mar 2000) |
| anterior occlusion | The occlusion of anterior teeth. Synonym: mesial occlusion. (05 Mar 2000) |
| aortic occlusion | A blockage of the aorta somewhere along its path. This can result in irreversible damage to the organs which depend on aortic blood below the level of the blockage. See: atherosclerosis. (27 Sep 1997) |
| balanced occlusion | The simultaneous contacting of the upper and lower teeth on the right and left and in the anterior and posterior occlusal areas in centric and eccentric positions within the functional range; used primarily in reference to the mouth, but also arranged and observed on articulators, developed to prevent a tipping or rotating of the denture bases in relation to the supporting structures. Synonym: balanced articulation, balanced bite. (05 Mar 2000) |
| bimaxillary protrusive occlusion | An occlusion in which both the maxilla and mandible protrude, causing the long axes of the maxillary anterior teeth to be at an extremely acute angle to the mandibular teeth; may be secondary to a skeletal or dental deformity, or both; seen commonly in blacks. (05 Mar 2000) |
| buccal occlusion | Malposition of a tooth toward the cheek, the occlusion as seen from the buccal side of the teeth. (05 Mar 2000) |
| gliding occlusion | <dentistry> The contact relationship of the occlusal surfaces of the upper and lower teeth when moving into and away from centric occlusion. Synonym: gliding occlusion. (05 Mar 2000) |
| mechanically balanced occlusion | A balanced occlusion without reference to physiologic considerations, as on an articulator. (05 Mar 2000) |
| pathogenic occlusion | An occlusal relationship capable of producing pathologic changes in the supporting tissues. (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) |
| retrusive occlusion | A biting relationship in which the mandible is forcefully or habitually placed more distally than the patient's centric occlusion. Synonym: distal occlusion. (05 Mar 2000) |
| graft occlusion | <physiology> Obstruction of flow in biological or prosthetic vascular grafts. (12 Dec 1998) |
