<p>A chemically curable dental restorative material is provided comprising a two-component paste-paste system wherein: (i) a first initiator-containing paste system comprises from about 15 to 40% by weight of a polymerizable methacrylic ester monomeric system comprising a crosslinking methacrylate monomer, at least one co-monomeric methacrylate diluent and a free radical-generating catalyst, and from about 60 to 85% by weight of an inorganic filler prepared by wet milling, surface etching milling and a silanizing milling; and (ii) a second accelerator-containing paste system comprises from about 15 to 31% by weight of a polymerizable methacrylic ester monomeric system comprising a cross-linking methacrylate monomer, at least one comonomeric methacrylate diluent and an inorganic amine accelerator and from 69 to 85% by weight of an inorganic filler prepared by wet milling, surface etching milling and a silanizing milling; said first and second paste systems being admixed in substantially equal proportions to form the chemically curable dental restorative material.</p> |
