Abstract (en)

[origin: WO9836729A1] 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.
