Outline of Final Research Achievements	CAD/CAM materials are reported to have excellent properties than conventional PMMA-based denture materials, but durability about CAD/CAM materials have not been well studied. This study aimed to evaluate the degradation of CAD/CAM materials by durability test. It was confirmed that the degradation of the CAD/CAM material which consisted of homogeneous dispersed nano sized fillers is smaller than that of conventional blocks by heat and acid conditions.
