occlusion /oc·clu·sion/ (ŏ-kloo´zhun) 1. obstruction. 2. the trapping of a liquid or gas within cavities in a solid or on its surface. 3. the relation of the teeth of both jaws when in functional contact during activity of the mandible. 4. momentary complete closure of some area in the vocal tract, causing the breath to stop and pressure to accumulate. abnormal occlusion malocclusion. balanced occlusion occlusion in which the teeth are in harmonious working relation. centric occlusion that in the vertical and horizontal position of the mandible in which the cusps of the mandibular and maxillary teeth interdigitate maximally. coronary occlusion complete obstruction of an artery of the heart. eccentric occlusion occlusion of the teeth when the lower jaw has moved from the centric position. habitual occlusion the consistent relationship of the teeth in the maxilla to those of the mandible when the teeth in both jaws are brought into maximum contact. lateral occlusion occlusion of the teeth when the lower jaw is moved to the right or left of centric occlusion. lingual occlusion malocclusion in which the tooth is lingual to the line of the normal dental arch. mesial occlusion the position of a lower tooth when it is mesial to its opposite number in the maxilla. normal occlusion the contact of the upper and lower teeth in the centric relationship. protrusive occlusion anteroclusion. retrusive occlusion distoclusion. venous occlusion the blocking of venous return.
occlusion [ŏ-kloo´zhun] 1. obstruction. 2. the trapping of a liquid or gas within cavities in a solid or on its surface. 3. the relation of the teeth of both jaws when in functional contact during activity of the mandible. 4. momentary complete closure of some area in the vocal tract, causing breathing to stop and pressure to accumulate. ![]() Normal occlusion of the primary molars. From Darby and Walsh, 1994. abnormal occlusion malocclusion. central occlusion (centric occlusion) occlusion of the teeth when the mandible is in centric relation to the maxilla, with full occlusal surface contact of the upper and lower teeth in habitual occlusion. coronary occlusion see coronary occlusion. eccentric occlusion occlusion of the teeth when the lower jaw has moved from the centric position. functional occlusion contact of the maxillary and mandibular teeth that provides the highest efficiency in the centric position and during all exclusive movements of the jaw that are essential to mastication without producing trauma.
occlusion 1. the act of closure or state of being closed; an obstruction or a closing off. 2. the relation of the teeth of both jaws when in functional contact during activity of the mandible. abnormal occlusion malocclusion. coronary occlusion see coronary occlusion. functional occlusion contact of the maxillary and mandibular teeth that provides the highest efficiency in the centric position and during all exclusive movements of the jaw that are essential to mastication without producing trauma. inflow occlusion a technique used in cardiac surgery to produce complete circulatory arrest by temporarily interrupting venous return. traumatic occlusion
any abnormality of occlusion which causes injury to structures within the mouth. Want to thank TFD for its existence? Tell a friend about us, add a link to this page, add the site to iGoogle, or visit the webmaster's page for free fun content. |
