  • Publication number: 20030124490
    Abstract: In the formation of dental bridges, the preferred material is a tightly-sintered aluminium oxide, and it is normal practice that the necessary bridge parts, namely two bridge anchors and a connecting intermediate link (pontic), are formed by a specialist and thereafter joined together in a dental laboratory where use is made of a melted glass as binding agent, after which the assembled bridge item is fired with porcelain. With the invention it has been found that considerable advantages can be achieved when a dispersion of said aluminium oxide or a material related herewith is used as binding agent, which after application between the assembly surfaces is heated until loose sintering is achieved, after which an infiltration of the sintered material by the glass is brought about by renewed or additional heating. There is hereby achieved a more simple working process as well as a stronger binding both between the assembly surfaces as well as between the bridge item and the porcelain with which it is fired.
