It is known that classical silver staining process can be introduced silver ions into glasses and silver nano-particles precipitate in glasses after heat treatment. The object of this study is to improve the mechanical properties of all-ceramic restorations fabricated by CAD/CAM systems using the silver staining process. Silver stain has increased Vickers hardness and fracture toughness of the surface and subsurface region of IPS Empress^R CAD block, because of an increase in residual compressive stress. The findings suggest that the silver staining process has improved the mechanical properties of all-ceramic restrations fabricated by CAD/CAM system.
