ABSTRACT:
The invention relates to a multi-component dental cement which contains as a first component an ethylenically unsaturated polymerisable compound, as a second component calcium hydroxide, calcium oxide or a precursor thereof and also a polymerisation initiator, the constituents of which can be contained in one or more cement components, which is characterized in that the ethylenically unsaturated polymerisable compound has both at least one .beta.-dicarbonyl group and also at least one acrylic, alkacrylic or vinyl aromatic group. Also included are a process for the production of a multi-component dental cement and the use of the described polymerisable .beta.-dicarbonyl compounds in calcium hydroxide dental cements.
