Interocclusal Record
Pronunciation: in-ter-uh-KLOOS-ul REK-ord
A physical registration of the spatial relationship between opposing dental arches, used to mount casts on an articulator.
Full Definition
An interocclusal record is a bite registration medium—typically wax, polyvinyl siloxane, or zinc oxide eugenol paste—that captures the positional relationship of the maxillary and mandibular teeth or edentulous ridges at a defined jaw position. In the dental laboratory, interocclusal records guide the accurate mounting of casts on an articulator so that occlusal relationships can be replicated during fabrication. Editors should distinguish this term from 'bite registration,' which is used colloquially for the same concept but may be considered less precise in formal clinical documentation. 'Centric relation record' and 'CR record' are specific subtypes.
Usage
Usage note: 'Interocclusal record' is preferred over 'bite registration' in formal laboratory and clinical documentation.
