Centric Occlusion vs. Centric Relation: What's the Difference?

Edited by Huma Saeed || By Sawaira Riaz || Published on December 29, 2023
Centric Occlusion is the position where upper and lower teeth fit together perfectly, while Centric Relation is the jaw's position when the condyles are in their most upward, backward, and centralized position.

Key Differences

Centric Occlusion refers to the ideal occlusion of the teeth, where the upper and lower teeth are in their best fit, usually during biting or chewing. This is a static relationship based on the contact between teeth. Centric Relation, on the other hand, is a concept related to the alignment of the jaw joints (temporomandibular joints) in their most unstrained position, independent of tooth contact.

In Centric Occlusion, the focus is on the optimal positioning of the teeth for effective mastication and aesthetics. It's a tooth-driven concept and is essential for the proper function of the dental arches. In contrast, Centric Relation is more about the functional position of the jaw and is considered a jaw-driven concept. It's used as a reference point in restorative dentistry and orthodontics.

The Centric Occlusion is often used in general dental practice to assess and treat common dental issues, focusing on how well the teeth occlude. Centric Relation is used in more complex cases, such as when reconstructing occlusions or treating temporomandibular joint disorders, where the position of the jaw is a crucial factor.

Achieving a proper Centric Occlusion is vital for everyday dental health, ensuring that biting and chewing do not cause undue wear or trauma. Centric Relation becomes particularly important in prosthetic dentistry and orthodontics, where the alignment of the jaw can impact the overall treatment plan.

Centric Occlusion is about the best fit of the teeth, while Centric Relation deals with the ideal positioning of the jaw joints. Both concepts are crucial in dentistry but are used differently depending on the context and the dental issues at hand.
