| Outline of Final Research Achievements |
The purpose of this research was to investigate the antimicrobial effect of silver nanoparticles applied to silicone soft denture. Evaluation of the properties of existing silicone soft liner was important, and investigation of the bond strength to denture metal and dynamic viscoelasticity before and after thermal cycle test was conducted. In addition, silver nanoparticles were carried on the surface of soft denture liner and the antibacterial effect was evaluated. The result, it was suggested that the bond strength and dynamic viscoelasticity of the soft denture liner in the long term use could be substantially maintained. It was not yet to be decided on the concentration and particle size that represents the antimicrobial effect of silver nanoparticles, but this research will be continued and determined the effective conditions of silver nanoparticles and the effect on the bond strength and dynamic viscoelasticity with silver nanoparticles to compare with the obtained results.
