HOSA Dental Terminology Practice

What is meant by Centric Relation?

1. Measurement of tooth wear over time

2. Arch-to-Arch relationship with condyles in an elevated position

3. Movement of the mandible during chewing

4. Interrelation of upper and lower teeth during speech

The correct answer is: Arch-to-Arch relationship with condyles in an elevated position

Centric Relation refers specifically to the maxillomandibular relationship when the condyles are in their anterior-superior position within the glenoid fossae with the articular discs interposed, and it is restricted to a purely bone-to-bone relationship. This position is clinically discerned when the patient is in maximum intercuspation and is repeatable, making it a precise anatomical and functional reference used by dental professionals. The importance of Centric Relation lies in its use for diagnosing and planning treatment for occlusal disorders, as it provides a reference for establishing a neutral relationship between the upper and lower jaws prior to making any adjustments or restorations.
