Abstract
The present invention relates to polymeric composites comprising inorganic fillers and organic, or organometallic, polymers. The filler compositions are used in the preparation of inorganic-organic polymeric composites, and, in particular, light curable composites. The composite fillers are used in dental applications, such as tooth restorations, for example, cavity fillings, adhesive compositions, veneers, crowns, bridges and teeth replacements. The inventive composition is a composite filler comprising porous inorganic particles having a diameter of 2-25 microns and a polymer occupying the pores of the porous inorganic particles, wherein the composite filler has a diameter of 2-25 microns.
