摘要：
The invention relates to a polymerizable dental material containing a) at least one curable aliphatic and/or cycloaliphatic monomer system having a refractive index that is measured at 23° C. and a wavelength of 589 nm of less than or equal to 1.50 that contains at least one aliphatic and/or cycloaliphatic bis(meth)acrylate and/or at least one aliphatic and/or cycloaliphatic bis(meth)acrylamide； and b) 15 to 80% by weight relative to the total mass of the dental material of at least one filler selected from the group of fused silica having a refractive index that is measured at 23° C. and a wavelength of 589 nm of 1.45 to 1.47, or cristobalite with a refractive index that is measured at 23° C. and a wavelength of 589 nm of 1.48 to 1.49, or combinations thereof. The radically polymerizable dental material has excellent storage properties and is formulated, in particular, as a two-component mixture containing components A and B. Subsequent to mixing components A and B, the polymerizable mixture cures quickly in the conditions present in the mouth and forms cured masses having outstanding mechanical and optical properties. The cured products can be used, in particular, for producing crowns and bridge material and as core buildup material.
