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.
Claims10
A low shrinking polymerizable dental material, comprising a mixture of
- (i) at least one polymerizable resin
- (ii) at least one polymerizable monomer
- (iii) at least one polymerization initiator and/or sensibilizer and a stabilizer and
- (iv) at least one filler in a content of 20 to 85 percent by weight;
- wherein the material has a volumetric polymerization shrinkage of less than 1.5%, such that it stiffens upon shear or pressure and does not relax within a predetermined the working time of the material due to its rheopex rheologic behavior.
