For a maxillary complete denture, which area is considered a primary stress-bearing area?

Correct answer: A. Residual alveolar ridge crest

• A. Correct. The residual ridge (with the horizontal/flat portion of the hard palate) is a primary stress-bearing area in the maxilla.
• B. The incisive papilla overlies the nerve/vessels and is a relief (non-stress) area.
• C. The mid-palatine raphe is non-resilient and is relieved, not loaded.
• D. Frena are relieved to avoid displacement of the denture.

Note: Both the residual ridge and the horizontal hard palate are classic primary stress-bearing areas of the maxilla.
