A composite material is described which contains polymerizable monomers plus a special transparent glass having high release of calcium ions and fluorine ions and, because of this release property and in particular of its optical properties, can be used as a restoration material in dentistry.

Polymerizable composite material

The invention relates to ion-releasing composite materials on the basis of polymerizable monomers. The material is characterized in that it contains one or more non-acid, non-ionic, hydrophilic crosslinker monomers, one or more non-acid, non-ionic, hydrophilic dilution monomers having a viscosity of &lE;1 Pas and at least one ion-releasing filler. The materials are suitable in particular for use as dental materials.

Ion-releasing composite material

Polymerizable dental materials, suitable as underfilling material, comprising at least one polymerizable monomer or prepolymer, a setting catalyst and inorganic fillers comprise as filler, a glass powder comprising of 40-75 wt-% CaO, 5-30 wt-% B.sub.2 O.sub.3 and 5-35 wt-% SiO.sub.2.
