Effect of powder/liquid ratio on physical and chemical properties of C&B Metabond.
The purpose of this study was to examine the effect of varying the powder/liquid ratio on the physical properties and the degree and rate of curing of C&B Metabond cement. The powder/liquid ratios evaluated had no effect on the tensile bond strength of Rexillium III to etched enamel or on the retention of cemented full cast crowns. The higher P/L ratio resulted in an increased vertical displacement of the cemented crowns. The rate of monomer conversion and the total conversion were not affected significantly by the different P/L ratios.
