Questions and Answers

What is the definition of centric relation?

  • The imaginary plane touching the occlusal surfaces of dental arches
  • The position of mandible where condyles are in their most retruded position relative to maxilla (correct)
  • The contact between maxillary and mandibular teeth determined by various mandibular movements
  • The occlusal contact between maxillary and mandibular teeth obtained by dental arches position

    • What does the term 'occlusal plan' refer to?

  • The contact between maxillary and mandibular teeth determined by various mandibular movements
  • The position of mandible where condyles are in their most retruded position relative to maxilla
  • The imaginary plane touching the occlusal surfaces of dental arches (correct)
  • The occlusal contact between maxillary and mandibular teeth obtained by dental arches position

    • How is centric occlusion defined?

  • The most retruded position of the mandible relative to the maxilla where the condyles are in their most upward and backward position in the glenoid fossa
  • The imaginary plane touching the occlusal surfaces of dental arches

    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.
