Kind Code:
A3
Abstract:
The invention relates to a polymerizable dental material comprising at least one paste component A and at least one paste component B, component A comprising at least one initiator of free-radical polymerization c) selected from the group of the barbituric acid derivatives and/or the malonylsulphamides, and component B comprising at least one organic compound d) comprising acrylic ester and/or methacrylic ester radicals, at least one metal compound e) and at least one halide and/or pseudohalide compound f). The polymerizable dental material is characterized in that component A, as a reactive paste former, comprises at least one organic compound a) derived from maleic acid and/or from fumaric acid and/or from itaconic acid, and/or at least one compound comprising at least one allyl and/or methallyl radical b). The polymerizable dental material has very good storability and cures rapidly after mixing of components A and B under mouth conditions, and forms cured compositions with excellent mechanical properties. These can be used particularly as a crown and bridge material or as dental cement.
