| Research Abstract |
The purpose of this research was to develop an antimicrobial soft denture liner having the moisture effect and photocatalytic function for patients with severe alveolar resorption and dry mouth. Rheological properties of commercial soft denture liners and denture adhesives and influence of chemical composition, such as the kind and content of monomers and cross-linking agents, on setting characteristic, water absorption, solubility and dynamic viscoelastic properties were evaluated. Furthermore, experiments in cytotoxicity and compatibility with denture cleansers were conducted. Theexperiments in influence of moisturizers and photocatalytic titanium dioxide on the physical properties were also being conducted. The results of the present research are considered to contribute thedevelopment of new type of soft denture liner.
