Which statement best describes centric relation?

• A. The Mandible Is in Centric Relation
• B. The Condyles Twist Around the Insertion of the Temporo-Mandibular Ligaments
• C. The Condyles Are Located in the Highest and Posterior Portion of the Glenoid Cavity
• D. The Mandible Is on the Maximum Protrusion Path

Answer: (A)

Centric relation is the maxillomandibular relationship where the condyles are in the most anterior–superior position against the articular eminences with the discs properly interposed, independent of tooth contact. Saying the mandible is in centric relation captures this specific, reproducible position of the mandible relative to the maxilla. The other options describe movements or positions not constituting CR: twisting around ligaments isn’t how CR is defined; the condyles being in the highest and posterior part of the fossa is incorrect for CR (CR is superior–anterior); and being on a maximum protrusion path refers to border movements, not CR.
