What is the ideal occlusal scheme for complete dentures?
Show answer and explanation
Correct answer: C. Bilaterally balanced occlusion (lingual occlusion)
C) Bilaterally Balanced Occlusion (lingual occlusion) — CORRECT.
Complete dentures require bilateral balance during all excursive movements to prevent tipping or dislodgment. The occlusal pattern is typically "lingual occlusion" (lingualized occlusion) where the upper palatal cusps occlude with the lower central fossae, providing balance while reducing lateral forces. This is the occlusal pattern WITHIN the BBO system.
A) Canine-protected: Used in natural dentition and implant-supported restorations — not for complete dentures (no proprioception).
B) Mutually protected: For natural teeth; not appropriate for complete dentures.
D) Unilateral balance: Would cause denture tipping on the non-working side.
