title: 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.
