The object of the invention is to provide an epoxy resin that is transparent and can be employed in dental fields for performing precise and transparent dental models that can be used in dental implants and in light curing materials, such as composite and polycarbonate materials. The transparent epoxy resin have to react to substance that allow to get away moisture and to strengthen chemical resistance, to improve transparency and impact strength, to reduce deformation under load, to increase abrasion resistance, and to improve environmental stress crack resistance and adhesivity. The grafted transparent epoxy resin can be used, as an example, by dental technicians to performing very precise and transparent dental models particularly helpful for building, as an example, crowns or bridges on dental implants having the possibilities to see the precise position of dental implants; or else building stump pin and inlay and onlay in, as an example, composite materials curing light and the transparent dental models allow the cross in every direction by the dental curing light.
