Finishing in denture fabrication involves which activity?

• A. Removing flash and refining margins
• B. Smoothing the denture surface
• C. Taking final impressions
• D. Designing occlusion

Answer: (A)

Finishing centers on cleaning up the denture after processing and bringing it to its final, precise form. The key task here is removing flash—the thin excess acrylic that extends beyond the intended border after processing—and refining the margins so the edge sits smoothly against the soft tissues. This border work is crucial because any overhangs or rough edges can irritate tissue, affect retention, and compromise comfort. Narrowing and smoothing the margins ensures a snug, uniform seal with the tissue and prepares the denture for polishing. Taking final impressions happens earlier in the workflow to capture the mouth's dimensions, and designing occlusion is planned before finishing as part of how the teeth will contact each other. Smoothing the denture surface is also part of finishing, but the specific activity most representative of finishing in many curricula is removing flash and refining margins.
