| 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) |
| vascular occlusion | A sudden blockage of a blood vessel usually with a blood clot. Blockage of a vein results in deep venous thrombosis. Blockage of an artery results in a surgical emergency. (27 Sep 1997) |
| 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) |
| central retinal artery occlusion | <ophthalmology> The sudden blockage of the retinal artery with a blood clot that commonly leads to a painless but irreversible blindness in that eye. (12 Jan 1998) |
| central retinal vein occlusion | <ophthalmology> The sudden blockage of the retinal vein with blood clot that commonly leads to a painless irreversible blindness in that eye. (12 Jan 1998) |
| 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) |
| retinal artery occlusion | Occlusion or closure of the central retinal artery causing sudden, usually nearly complete, loss of vision in one eye. Occlusion of the branch retinal artery causes sudden visual loss in only a portion of the visual field. (12 Dec 1998) |
| retinal vein occlusion | <ophthalmology> Occlusion of the retinal vein. Those at high risk for this condition include patients with hypertension, diabetes mellitus, arteriosclerosis, and other cardiovascular diseases. (12 Dec 1998) |
| 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) |
