Abstract
A method for making artificial tooth bridges having a ceramic densely sintered high strength individual core veneered with porcelain using powder metallurgical methods, wherein the individual bridge parts are joined together as a bridge core with glass, which in molten condition wets the ceramic core material. The glass therefore finds its way into the gap between the bridge parts and reacts with the ceramics so that during cooling it forms a strong joint between the individual densely sintered ceramic bridge parts.
