Compressive strengths of a new foil and porcelain-fused-to-metal crowns
Abstract:
This study evaluated the compressive strengths of Renaissance foil and porcelain-fused-to-metal crowns on polycarbonate test dies. Both crown types were veneered with feldspathic porcelain. The compressive strength of the PFM crowns, 1895 +/- 317 N, was statistically higher than that of the Renaissance foil crowns, 1060 +/- 89 N. Comparison of the Renaissance foil crown's compressive strength to published biting forces indicated that the Renaissance crown should function without difficulty.

Strength of Cement
For compressive strength tests, ASTM C 109-05 standards prescribe a cement-sand mix ratio of 1:2.75 and a water/cement ratio of 0.485 for making 2-inch cubes. These cubes are mixed, cast, and cured in saturated lime water at 23°C until testing. Flexural strength testing, outlined in ASTM C...
