Occlusion
The contact relationship between the maxillary and mandibular teeth when the jaws are brought together.
Full Definition
In dentistry, occlusion refers to the way in which upper (maxillary) and lower (mandibular) teeth meet during jaw closure, chewing, and other mandibular movements. It encompasses static occlusion (teeth in maximum intercuspation) and dynamic occlusion (contacts during jaw movement). Classification systems such as Angle's classification (Class I, II, and III) are used to describe malocclusion. Editors must be careful not to confuse dental occlusion with the medical use of 'occlusion', which refers to a blockage of a vessel or passage; context determines the correct meaning.
Usage
Usage note: When editing cross-specialty documents, clarify whether 'occlusion' refers to the dental (bite) meaning or the medical (blockage) meaning to avoid reader confusion.
