Abstract: A process' for the modification of a particulate reactive filler for a dental ionomer cement, comprising (a) providing a particulate reactive filler; and (b1) treating the surface of the particulate reactive filler with a surface modifying agent for obtaining a surface modified particulate reactive filler displaying ligand groups for a transition metal; and (b2) treating the surface modified particulate reactive filler with an agent containing the transition metal for complexing the transition metal with the ligand groups displayed on the surface of the surface modified particulate reactive filler; and/or (c) treating the surface of the particulate reactive filler with a surface modifying transition metal complex which is a reaction product of a surface modifying agent and a transition metal precursor compound, for obtaining a transition metal complex surface modified particulate reactive filler for a dental ionomer cement.
