Centric Relation Definition
Centric relation is best defined as a relationship in which the:
- A.Condyles are seated in their most anterosuperior position against the articular eminence
- B.Condyles are pushed fully posterior in the fossa
- C.Teeth are in maximum intercuspation
- D.Lateral pterygoid is maximally contracted
Answer: A.Condyles are seated in their most anterosuperior position against the articular eminence
Why
Centric relation is the maxillomandibular relationship in which the condyles are in their most anterosuperior position in the glenoid fossae, against the articular eminences, with the disc properly interposed. It is independent of tooth contact. Maximum intercuspation is a tooth-based reference. Forced posterior positioning is not a physiologic landmark.
041
Anterior Guidance
During protrusive movement of the mandible, posterior teeth should ideally:
- A.Disclude
- B.Bear all the load
- C.Make heavy contact with the opposing teeth
- D.Slide laterally across each other
Answer: A.Disclude
Why
Anterior guidance during protrusive movement should cause the posterior teeth to disclude, protecting them from harmful lateral loading. This is part of the mutually protected occlusion concept, where anterior teeth guide excursive movements while posterior teeth bear vertical load during maximum intercuspation.
083
Group Function
In group function occlusion, lateral excursion produces contact of the:
- A.Multiple posterior teeth on the working side
- B.Canine only on the working side
- C.Anterior teeth only
- D.Non-working side molars only
Answer: A.Multiple posterior teeth on the working side
Why
Group function distributes lateral excursive loading across multiple teeth on the working side, including posterior teeth. Canine guidance, by contrast, isolates the load to the canine alone. Group function may be appropriate when the canines are worn, missing, or periodontally compromised. Non-working side contacts are generally undesirable.

SDF Connection

Occlusion is the Force lens of the Structural Decision Framework made visible: every contact is a load path through teeth, restorations, and the TMJ.

Structure: Class of occlusion, contact pattern, articulator setup, vertical dimension, and the supporting cusp anatomy.
Force: Centric vs eccentric loading, lateral guidance, parafunctional load, and the force vectors at the tooth, restoration, and joint.
Time: Wear progression, restoration aging, TMJ adaptation, and the parafunction history that drives both.
Stability: Will the occlusal scheme stay protective: anterior guidance, posterior support, joint position, and the muscle balance that holds it.

Structural Decision Framework (SDF) is a clinical reasoning model by Dr. Isaac Sun, DDS.
