A compressive strength study of an all-ceramic crown.
Eighteen crowns were subjected to the same occlusal loading. The porcelain-fused-to-metal crown was more than twice as resistant to the load than the Cerestore crown and almost four times stronger than the porcelain crown. These tests show that porcelain fused to metal has demonstrated its capability as a strong posterior restoration. The Cerestore crown, though superior to the porcelain crown, is significantly less resistant to fracture than the porcelain-fused-to-metal restoration.
