Improved cements containing phosphate polymers.
The mechanical properties of two commercially available dental cements, a zinc phosphate cement and a carboxylate cement, were substantially improved by adding a polymeric phosphate acid to the cement liquids. The improvements can be explained in terms of the change in physico-chemical nature of the modified cements.
