Abstract
A method for the production of full or partial dental restorations including veneers, crowns, inlays, onlays, and bridge structures, and dental restorations produced by the method. The method utilizes the technique of flame spraying to form a basal layer of a technical ceramic based material upon which porcelains are applied to produce a strong, aesthetically acceptable and custom made dental restoration. The technical ceramic based material may be Alumina, Zirconia, Titania, or combinations thereof, and the flame spraying may be a direct method or an indirect method. The technical ceramic based material may include small amounts of silicate based materials.
