    摘要： Radically polymerizable dental material which contains (a) at least one polyfunctional radically polymerizable monomer, (b) at least one further radically polymerizable monomer which can be monofunctional or polyfunctional, (c) at least one photoinitiator for the radical polymerization and (d) at least one filler. The material is characterized in that the mixture of the monomers (a) and (b) has a refractive index of from 1.50 to 1.70 and in that the refractive index of the monomer mixture before the curing corresponds to the refractive index of the filler used or is higher by up to 0.013 and after the curing is higher than the refractive index of the filler by at least 0.02.
