Abstract

Chronological change in physical properties of novel silicone-rubber denture relining material: Denture Relining and tensile bond strength (Tbs) to denture base resin immersed in water at 37°C for 1 day to 5 months were investigated. Further Tbs after immersion in denture cleanser solution for 1 month was studied.<BR>Shore hardness of Denture Relining Soft type (DRS) and Denture Relining Medium type (DRM) showed 35 and 46 after 1-day immersion. Tensile strength of DRS and DRM showed 2.95 and 2.94 MPa after 1-dayimmersion, then increased chronologically, and showed 3.81 and 4.37 MPa after 5-month immersion. Tearstrength of DRS and DRM showed 10.21 and 9.18 kN/m after 1-day immersion, then unchanged or slightlyincreased chronologically, and showed 11.14 and 9.22 kN/m after 5-month immersion. Tbs of DRS and DRM showed 2.52 and 2.30 MPa after 1-day immersion, then chronologically increased, and showed 3.83 and 2.82 MPa after 5-month immersion. These values were significantly superior to those of two ordinary siliconerubberrelining materials.<BR>Tbs of DRM after immersion in denture cleanser solution were changed according to the kind of thedenture cleanser. The ferment denture cleanser containing neutral peroxide did not decrease Tbs of DRM andwas thought to be an effective cleanser for denture plaque control.
