Abstract

The present invention relates to novel free-radically curable dental compositions, comprising chain-like and/or cyclic and/or cage-type polysiloxanes substituted by free-radically polymerizable groups and having at least 3 silicon atoms and/or mixed forms thereof, disiloxanes substituted by free-radically polymerizable groups, optionally one, two, three or more free-radically curable dental monomers having no silicon atom, fillers, initiators and/or catalysts for free-radical polymerization, and also further customary additives, to the cured dental products formed from the dental compositions of the invention, and to the respective use thereof as dental material, especially as flowable filling composites (called “flow materials”), core buildup materials and luting cements. The invention further relates to a method for producing the dental compositions and to a process for producing a respective dental product. Additionally claimed are inventive kits containing the novel free-radically curable dental compositions.
