Centric Occlusion vs. Centric Relation: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Centric Occlusion refers to the jaw position where the teeth are in full contact, while Centric Relation is the jaw position where the lower jaw is positioned farthest back and highest up, regardless of tooth contact.
Key Differences
Centric Occlusion (CO) refers to the position where the teeth are in maximum intercuspation or contact, often considered the 'bite' position. Centric Relation (CR), on the other hand, is a jaw position where the condyles are in their most superior-anterior position in the glenoid fossa, which is independent of tooth contact.

Centric Occlusion is significant in dental practices for restorative procedures and understanding functional tooth contact. Centric Relation is crucial for diagnosing and treating temporomandibular joint disorders and for complete denture fabrication.

Centric Occlusion is achieved naturally and is influenced by the contact between teeth. Centric Relation is a more theoretical and idealized jaw position, not necessarily achieved naturally but important in dental occlusion analysis.

The relevance of Centric Occlusion lies in its day-to-day application, affecting how people chew and bite. Centric Relation is more about the relationship of the jaw joints and the alignment of the mandible to the skull.

Dentists assess Centric Occlusion for wear patterns, misalignment, and other functional aspects of the teeth. In contrast, Centric Relation is assessed to understand the jaw joint's health and for planning prosthodontic treatments.
