Which procedure fills the void between the denture and the arch with hard acrylic?

• A. Hard Reline
• B. Rebase
• C. Immediate Denture
• D. Impression Materials

Answer: (A)

Hard reline is the process of adding rigid acrylic resin to the inner (intaglio) surface of an existing denture to fill the space that has formed between the denture base and the tissue. This creates a new, congruent fit to the mucosa, improving retention, stability, and comfort without replacing the teeth or making a new denture from scratch. Rebasing would replace the entire denture base while keeping the current teeth arrangement, which isn’t about adding material to conform to the tissues. An immediate denture is a denture placed right after tooth extraction, not a method for correcting fit after use. Impression materials are used to capture a mold, not to adjust the fit of an already worn denture. So, the procedure that fills that void with hard acrylic is a hard reline.
