Polishing is primarily used to do what?

• A. Smoothing the surface of the denture
• B. Removing material to adjust margins
• C. Taking new impressions
• D. Smoothing and shining the surface without changing contour

Answer: (D)

Polishing is a finishing step that creates a smooth, glossy denture surface while preserving the denture’s contour. The goal is to remove microscopic scratches and even out the surface so it’s comfortable for the soft tissues and easier to clean, with a high shine for aesthetics. It doesn’t remove material to adjust margins, nor does it involve taking new impressions. So the description that fits best is smoothing and shining the surface without changing contour.
