Abstract
A method is disclosed in which modified and generic dental resins are combined as mixtures with reactive polymeric nanoparticles (RPNPs). Nanoparticles as additives clearly demonstrate that the RPNPs significantly influence the mechanical and shrinkage properties of the matrix and composites.
