For occlusal scheme of DENTATE patients (not denture patients), which is considered MOST ideal?

Correct answer: A. Canine-guided occlusion (mutually protected occlusion)

• A. Correct. For natural dentition (dentate) patients, CANINE-GUIDED (canine-protected) occlusion — part of mutually protected occlusion — is considered the ideal. During lateral excursions, the canine contacts guide the mandible while posterior teeth disclude, protecting them from lateral forces. Canines are ideal guides due to their long roots, favorable crown-to-root ratio, and position.
• B. Bilateral balanced occlusion is ideal for COMPLETE DENTURES — not for natural dentition (it applies to dentures to prevent tipping).
• C. Lingual occlusion is a denture occlusal scheme — not used for natural dentition.
• D. Group function (all posterior teeth contact on the working side) is acceptable for natural dentition when canine guidance is not achievable, but canine guidance is considered more ideal.
