occlusion

[ŏ-kloo´zhun]

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.

cen·tric oc·clu·sion

1. the relation of opposing occlusal surfaces that provides the maximum planned contact and/or intercuspation;

2. the occlusion of the teeth when the mandible is in centric relation to the maxillae.

Synonym(s): centric contact

As the contractures were released, the patient was gradually able to close his mandible nearer the original centric occlusion. This required occasional modification of the maxillary palatal ramp.

Key Words: Anterior open bite, centric occlusion, orthodontic.

Anterior open bite is said to exist when there is an actual vertical gap between the upper and lower incisors with the teeth in centric occlusion.1 Anterior open bite as defined by Subtelny and Sakuda2 is the deviation in the vertical relationship of the maxillary and mandibular dental arches with a definite lack of contact in the vertical direction between opposing segments of teeth.

A person was labeled as having an anterior open bite if there was a lack of vertical overlap of upper incisors on the labial surface of lower incisors in centric occlusion.10 SPSS (16.0) was used to analyze the data statistically.

These effects could be attributed to the class 2 elastics mecha- nism causing forward mandibular dento-alveolar move- ment during treatment decreasing the maxillary-man- dibular plane angle or due to leveling of the curve of spee during treatment leading to better inter-cuspation of the buccal teeth in centric occlusion.23 Most authors quote the wedging-hypothesis24-25 to justify the de- crease in anterior facial height following treatment with 1st premolar extractions.

* Flush terminal plane: The distal surfaces of maxillary and mandibular primary second molars lie in the same vertical plane in centric occlusion.

* Distal step: The distal surface of the mandibu-lar primary second molar is distal to the distal surface of the maxillary primary second molar in centric occlusion.
