Abstract

The invention relates to a dental material with at least one polymerizable binder and at least one filler containing a redox-initiator system for the radical polymerization, which comprises an initiator and an activator. The material is characterized in that the filler contains a homogeneous mixture of a first part of the filler, which is mixed with the initiator, a second part of the filler, which is mixed with the activator, and a third part of the filler, which does not contain a component of the initiator system. The materials are particularly suitable as cements and filling materials.
