What is the purpose of an intentional chair-side reline in denture maintenance?

• A. To reanalyze occlusion.
• B. To change the shade of the denture teeth.
• C. To improve the fit of an existing denture by adding material to the tissue surface and relining contact with mucosa.
• D. To remove loose material from the denture.

Answer: (C)

Improving how the denture seats on the gums is the idea behind an intentional chair-side reline. In this procedure, material is added to the tissue-facing surface of an existing denture while it’s in the mouth, so the intaglio surface can better match the current contours of the remaining tissue. This reestablishes intimate contact with the mucosa, restoring a better border seal and enhancing retention and stability. It’s done chairside for a quick, in-mouth update without making a new denture. It doesn’t involve changing the shade of the teeth or reanalyzing occlusion, and it isn’t about removing loose material.
