  • Low shrinking polymerizable dental material
    Publication number: 20040229972
    Abstract: The invention describes a low shrinking polymerizable dental material, comprising a mixture of a polymerizable resin, a polymerizable monomer, a polymerization initiator and/or sensibilizer and a filler in a content of about 20 to about 85 percent. The volumetric shrinkage during polymerization is less than about 1.5 Vol.- % due to its rheopex behavior.
    Type: Application
    Filed: June 15, 2004
    Publication date: November 18, 2004
