Which step directly affects patient comfort by refining borders and contours after processing?

• A. Finishing
• B. Polishing
• C. Heat Injection Processing
• D. ASAP

Answer: (A)

Finishing directly shapes and trims the edges where the prosthesis meets the tissue, refining borders and contours so the appliance seats comfortably without irritating the mucosa. By removing excess material, smoothing sharp margins, and carefully contouring the intaglio surface to fit the arch, finishing eliminates high spots and overextensions that cause discomfort. Polishing comes after finishing to smooth the already correct contours, but it’s finishing that makes the border adjustments that most affect comfort. Heat Injection Processing and ASAP aren’t standard steps for altering borders, so they don’t impact patient comfort in the same direct way.
