Research Abstract

We evaluated the static viscoelastic properties and setting characteristics of commercial resilient denture liners and tissue conditioners. Relationship between molecular weight of polymer powders and powder/liquid ratio, and stress relaxation behavior of the tissue conditioners were also determined. Solubility and absorption of water of these materials were measured. Previously measurement of static viscoelastic properties was employed to evaluate physical properties of soft denture liners. However, we used the dynamic mechanical analysis in order to determine the physical properties more rigorously. The same generic materials showed the same viscoelastic properties, and the wide range of these properties was observed among the materials. Furthermore, we evaluate the relationship between the dynamic viscoelasticity of soft liners and masticatory function. This study demonstrated that the improvement of masticatory function was found to be greater in the soft liners having viscoelastic properties than those having elastic properties. As stated above, poly (butyl methacrylate) or similar polymer are found to be suitable for the powder of tissue conditioners. Also the acrylic polymer is found to be suitable for the resilient denture liners. We have evaluated the influence of plasticizer type and its content on dynamic viscoelasticity. We planed to evaluate the relationship between monomer type and some properties such as viscoelastic properties, solubility and absorption in order to develop the acrylic resilient denture liners having high durability.
