ABSTRACT:
Novel dental polymeric compositions useful as an adhesive dental restoration material are described. The compositions are based on a polymer obtained by the reaction of methacryloxyethyl trimellitic acid anhydride and methyl methacrylate monomer, in the presence of a free radical catalyst, being characterized by the fact that they contain at least one compound selected from the group consisting of silver, nickel, tin, silicium, copper and titanium or their oxides. The preferred amount of these compounds is in the range of between 2% and 20% by volume of the polymer. The compounds should be finely ground, possessing a particle size in the range of between 5 to 50 microns. Optionally, the compositions will contain a material capable to release anions, most preferred being fluoride-based material, in an amount of between 1% to 10% by weight of the composition. The compositions were found to impart bonding to fresh or old amalgam, as well as to dentin, enamel, porcelain and various alloys.
