Study Notes
Definitions and Concepts in Dental Occlusion
-
Centric Relation: A maxillomandibular relationship where the condyles are in the anterior-superior position within the glenoid fossae, which is restricted to the osseous structures with no regard to tooth contact.
-
Occlusal Plane: The imaginary plane that represents the plane of occlusion of the teeth with relation to the horizontal axis of the body, typically formed by the incisal edges of the anterior teeth and the cusp tips of the posterior teeth.
-
Centric Occlusion: Also known as maximal intercuspation, it is the occlusion of opposing teeth when the jaw is closed in the maximum intercuspal position, providing the greatest contact between the upper and lower teeth.
-
Jaw Relations: Refers to the positional relationships between the maxilla (upper jaw) and mandible (lower jaw) during various functional and non-functional movements, important for understanding occlusion and dental treatments.
-
Protrusive Relation: In a dental context, it describes the position of the mandible when it is slid forward (protruded) from centric occlusion, and it is essential for evaluating anterior dental contacts and determining functional movements of the jaw.
