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.

func·tion·al oc·clu·sion

1. any tooth contacts made within the functional range of the opposing teeth surfaces;
2. occlusion that occurs during function.

An ideal functional occlusion with adequate overjet and overbite requires among other factors an ade- quate size ratio between upper and lower teeth.
131416 Moreover in nonsurgical method incomplete anatomical restoration can cause facial asymmetry and inclination of the occlusion plane as well as functional occlusion problems such as premature contact in protrusion and lateral protrusion.
The dentist must be aware that before a restoration can be permanently placed in a patient's mouth it must meet all the criteria of the optimal functional occlusion.
