Prosthodontics & Occlusion · single question
A final impression is satisfactory except for poor margin detail. What is the most likely reason?
Show answer and explanation
Correct answer: A. Insufficient soft tissue retraction
- A. CORRECT. Without adequate gingival retraction the margin area is not captured, producing poor margin detail.
- B. INCORRECT. A small tray would cause broad distortion, not isolated margin loss.
- C. INCORRECT. Moving the tray after seating causes general distortion, not specifically missing margins.
