Abstract

The structure of the bond between dental aluminous porcelain and tin oxide coated platinum foils, used in dental jacket crowns, has been studied using analytical electron microscopy of crosssectioned specimens. It has been shown that the tin oxide is in the form of stannic oxide (SnO2) and that some of the oxide dissolves into the glass. It has also been demonstrated that the platinum foil is strained immediately adjacent to the interface.
