When constructing a complete lower denture, the occlusal plane at the retromolar pad should be placed at which level?
Show answer and explanation
Correct answer: C. At 1/2 (midpoint) of the retromolar pad
- A. ❌ 1/4 of the retromolar pad is too inferior.
- B. ❌ '5mm below' would position the plane too low.
- C. ✅ Correct. The occlusal plane of the mandibular complete denture should be at the MIDPOINT (1/2) of the retromolar pad height. This provides correct posterior occlusal plane height relative to the anatomy.
