| 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) |
| mesenteric artery occlusion | Obstruction of arterial flow in the mesenteric circulation by an embolus or thrombus; usually refers to occlusion of the superior mesenteric artery, although atherosclerotic narrowing may involve all three major splanchnic branches (coeliac, superior, and inferior mesenteric). (05 Mar 2000) |
| mesenteric vascular occlusion | Obstruction of the flow in the mesenteric circulation by atherosclerosis, emboli or thrombi, stenosis, trauma, and compression or intrinsic pressure from adjacent tumours. Rare causes are drugs, intestinal parasites, and vascular immunoinflammatory diseases such as periarteritis nodosa and thromboangiitis obliterans. (12 Dec 1998) |
| mesial occlusion | Occlusion in which the mandibular teeth articulate with the maxillary teeth in a position anterior to normal. Synonym: anterior occlusion, mesio-occlusion. Synonym: mesioclusion. (05 Mar 2000) |
| mesio-occlusion | Occlusion in which the mandibular teeth articulate with the maxillary teeth in a position anterior to normal. Synonym: anterior occlusion, mesio-occlusion. Synonym: mesioclusion. (05 Mar 2000) |
| physiologically balanced occlusion | A balanced occlusion that is in harmony with the temporomandibular joints and the neuromuscular system. (05 Mar 2000) |
| physiologic occlusion | Occlusion in harmony with functions of the masticatory system. (05 Mar 2000) |
| components of occlusion | The various factors involved in occlusion, such as the temporomandibular joint, the associated neuromusculature, the teeth, and the denture-supporting structures. (05 Mar 2000) |
| working occlusion | working contacts |
| coronary occlusion | Blockage of a coronary vessel, usually by thrombosis or atheroma, often leading to myocardial infarction. (05 Mar 2000) |
| posterior occlusion | The most effective contact of the molar and bicuspid teeth of both jaws which allows for all the natural movements of the jaws essential to normal mastication and closure. Synonym: posteroclusion. (05 Mar 2000) |
| postnormal occlusion | A tooth occluding in a position distal to normal. Synonym: disto-occlusion, postnormal occlusion, retrusive occlusion. Synonym: distoclusion. (05 Mar 2000) |
