Outline of Final Research Achievements

Three-Dimentional-(3D) printed resins generally have lower mechanical and physicochemical properties than those of CAD/CAM resin composite blocks. In order to improve material properties of 3D-printed resins,, the objective of this study was to develop novel 3D printing material for dentures with excellent physicochemical and mechanical properties. Experimental 3D-printed resins were prepared from silane-treated silica fillers and acrylic resins. Their mechanical and physicochemical properties were evaluated. The results showed that the mechanical and physicochemical properties of the experimental 3D printed resin were equivalent to or better than those of commercially available CAD/CAM resin composite. The results suggested that the experimental 3D-printed resin is a promising material as denture teeth.
