  • Ceramic inlay and process for making same
    Patent number: 5368831
    Abstract: A process for making a ceramic inlay for filling a cavity in a tooth. A piece of metal foil is pressed into a depression in a jig, where the depression approximates the shape of the cavity; the pressed metal foil is annealed and the pressing and annealing steps are repeated until the foil has a concave depression roughly the same size and shape as the cavity. A ceramic layer is built up on the concave foil to form a ceramic inlay substantially reconstructing the tooth.
