    Study Notes

    Relining and Rebasing

    • The main purpose of relining is to refit a denture by resurfacing the tissue side of the denture to ensure a better fit and improve the oral health of the patient.

    Difference between Relining and Rebasing

    • Relining is a process of resurfacing the tissue side of a denture, whereas rebasing involves replacing the entire denture base with a new one.

    Material Used for Relining

    • The most common material used for relining is acrylic resin.

    Advantage of Relining and Rebasing

    • The main advantage of relining and rebasing is that it improves the fit and retention of the denture, enhancing the overall comfort and confidence of the patient.

    Contraindications for Relining and Rebasing

    • Relining and rebasing are contraindicated when there is evidence of severe bone resorption or extensive tissue damage, or when the denture is severely damaged or incompatible with the patient's oral anatomy.
