Porcelain-fused-to-metal post and core: an esthetic alternative

Custom cast metal post and cores used to retain all-ceramic restorations are indicated in endodontically treated teeth when little clinical crown remains. The metal cores of these post and core restorations block light transmission and create a graying effect when used in support of all-ceramic restorations. This article describes a technique to minimize this effect using custom cast porcelain-fused-to-metal post and cores to achieve a more natural esthetic result.
