| 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) |
| curve of occlusion | A curved surface which makes simultaneous contact with the major portion of the incisal and occlusal prominences of the existing teeth, the curve of a dentition on which the occlusal surfaces lie. Synonym: occlusal curvature. (05 Mar 2000) |
| protrusive occlusion | Occlusion which results when the mandible is protruded forward from centric position. (05 Mar 2000) |
| 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) |
