Outline of Final Research Achievements	The aim of this study was to investigate the flexural properties of denture base resin cross-linked with methacrylated dendrimer including 12 or 24 methacrylate groups. The results of this study suggest that by adding cross-linking agents the flexural strength were influenced. Dendrimer with 12 methacrylate groups may be an alternative as a crosslinker of conventional denture base resin, and the flexural strength using PMMA powder after heat treatment at 130°C were significantly increased.
