Porcelain-fused-to-metal (PFM) restorations became available to the dental profession in the late 1950s. By the mid-1960s, they were becoming popular as an alternative to porcelain jacket crowns and three-quarters-gold alloy restorations. The concept of fusing ceramic to metal was criticized by some clinicians, because gold alloy restorations were the state of the art, well proven and long lasting. At that time, criticism of PFM included complaints such as wear of opposing tooth structure, necessity for deep tooth preparations, only moderate esthetic acceptability, poor fit of restorations and use of base metals for substructures.
