Describe the typical finishing protocol for denture acrylic resin.

• A. Trim, smooth, polish with progressive abrasives, and finish with denture polish to a high gloss.
• B. Sandblast, roughen, and seal.
• C. Rinse with water only.
• D. Apply glaze only.

Answer: (A)

Finishing denture acrylic resin centers on creating a smooth, high-gloss surface by removing excess material, smoothing irregularities, and then polishing to a durable shine. Start by trimming away any flash and excess acrylic around borders to shape the denture accurately. Next, smooth the surfaces with progressively finer abrasives to remove scratches and micro-roughness, preparing the material for polishing. The final step uses a denture polish and a buffing or polishing wheel to bring the surface to a high gloss. This sequence yields a comfortable intaglio surface, easy cleaning, and good esthetics while reducing plaque retention. Roughening or blasting the surface isn't suitable for final finishing because it creates irregularities that can harbor bacteria and irritate tissues. Rinsing with water alone doesn't alter texture or shine, so it leaves residues and roughness. A glaze alone doesn't address surface roughness or provide a durable, long-lasting polish, so it doesn't meet the finishing goals for denture bases.
