Abstract

The invention relates to fluoride-releasing, polymerizable dental composite aterials having good mechanical stability, containing: PA1 (a) one or more ethylenically unsaturated polymerizable monomers based on di- or multi-functional (meth)acrylates; PA1 (b) initiators and optionally activators; and PA1 (c) usual fillers, and optionally pigments, thixotropic agents, plasticizers and other auxiliaries; and PA1 (d) one or more sufficiently water-soluble inorganic complex fluorides of the general formula EQU A.sub.n MF.sub.m PA1 wherein, PA1 A is a monovalent cation, M is a metal of the III-V main group or II-V sub-group, n is a whole number from 1 to 3 and m is whole number from 3 to 6.
