The present invention relates to a radically polymerizable dental material comprising (a) at least one multifunctional radically polymerizable monomer, (b) at least one further radically polymerizable monomer which may be monofunctional or multifunctional, (c) at least one photoinitiator for the radical polymerization, and (d) at least one filler. The material is characterized in that the refractive index of the mixture of monomers (a) and (b) is between 1.50 and 1.70, and in that the refractive index of the monomer mixture before the curing process corresponds to the refractive index of the filler used, or is at most 0.013 higher than the refractive index of the filler, and is at least at most 0.02 higher than the refractive index of the filler after the curing process. |
