<p>The present invention relates to a method for making artificial tooth bridges consisting of a ceramic densily sintered high strength individual core (B) veneered with porcelain (A) using powder metallurgical methods. According to the method the individual densely sintered bridge parts are joined together to 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 it during cooling forms a strong joint between the individual densely sintered ceramic bridge parts.</p> |
