What procedure involves adding material to the tissue-facing surface of a denture to improve fit?

• A. Relining
• B. Replacing
• C. Recasting
• D. Reworking

Answer: (A)

Relining involves adding material to the tissue-facing surface of a denture to improve fit. Over time, the soft tissues in the mouth can change shape or compress, causing a denture to loosen or rub. By applying new denture base material to the inner surface, a relined denture re-establishes close contact with the mucosa, improving stability, comfort, and retention without needing a new denture. This can be done chairside in a single visit or in a lab setting, depending on the technique used. Replacing would mean making an entirely new denture rather than adding material to the existing one. Recasting involves melting and reforming the denture base, essentially remaking it rather than simply adding material to the surface. Reworking refers to general adjustments or modifications to the denture and does not specifically describe adding material to the tissue-facing surface to improve fit.
