Centric relation is best described as:

Centric relation is best described as:

• A. A maxillomandibular relationship independent of tooth contact with condyles in anterior-superior position
• B. The occlusion of opposing teeth when the mandible is in centric relation
• C. The complete intercuspation of the opposing teeth
• D. An untranslated hinge position about the transverse axis

Answer: (A)

Centric relation is a reproducible maxillomandibular relationship defined by the jaw joints, not by how the teeth touch. In this position, the condyles are seated anteriorly and superiorly against the articular eminences with the discs properly interposed, and this position is independent of any tooth contact. That joint-based, tooth-independent reference is what makes centric relation a reliable starting point for prosthodontic records and treatment, because it reflects a consistent position of the mandible regardless of how the teeth occlude. The other descriptions mix in tooth contact or describe a purely hinge-based position. Centric relation is not about the occlusion or intercuspation of the opposing teeth, and it is not simply a untranslated hinge position around the transverse axis; it centers on the condyle-disc apparatus in the anterior-superior position.
