Before beginning complete denture treatment, which factor is MOST important to assess?

Correct answer: B. The patient's expectations

• A. VDO is a technical parameter established during the procedure, not the primary pre-treatment determinant of success.
• B. CORRECT. Unrealistic patient expectation is the single strongest predictor of dissatisfaction with complete dentures, and it predicts outcome better than any anatomical variable. A patient who expects a denture to function like natural dentition will be unhappy with a technically excellent prosthesis. Anatomy can be worked around; expectations must be aligned before you start.
• C. The age of the previous prosthesis is useful history but not the governing factor.
• D. Ridge form matters greatly for retention and stability, but a poor ridge with a well-informed patient produces a far better outcome than an excellent ridge with an unrealistic one.

Note: Useful predictor: ask what the patient disliked about the previous denture. Specific, concrete complaints are workable. Diffuse or unfixable complaints ('it never felt like me') predict difficulty regardless of technique.
