Brückenzahn.
EMI1.1
Die Erfindung betrifft eine weitere Ausgestaltung des Brückenzahnes nach dem österr. Patente Nr. 154219 und besteht darin, dass der aus einem geschlitzten Platin-Iridium-Röhrchen, einem Stege (Bügel) und einem Lotröhrchen gebildete Metallkörper durch einen Bügel aus einem massiven Metall, beispielsweise aus 20%igem Platin-Iridium oder einem andern Metalle mit annähernd gleichem Ausdehnungskoeffizienten, mit seitlichen Verbreiterungen, welche die Verbindung mit dem Nachbarzahne ermöglichen, ersetzt wird. Auf diesem massiven Metallstücke ist als Kern eine Grund-bzw. Porzellanmasse mit einem Ausdehnungskoeffizienten, der das Aufbrennen auf das Metallstück blasen-und sprungfrei gestattet, aufgebrannt, der wieder mit einem Farbporzellan überbrannt wird.
Dadurch ist ein fertiger Einzelbrückenzahn geschaffen, der ohne Nieten, Plattieren usw. ohne weiteres verarbeitet und mit einem oder mehreren Brückengliedern, Kronen oder Inlays und andern Stützpunkten verlötet werden kann.
Damit ist auch dem Praktiker, welcher an dem höheren Preis, den der massive Platin-IridiumBügel mit seinen seitlichen Metallstücken bedingt, keinen Anstoss nimmt, die Möglichkeit gegeben, einfachst ohne jeder Manipulation einen vollwertigen Brückenzahn herzustellen.

Pontic.
EMI1.1
The invention relates to a further embodiment of the bridge tooth according to Austrian patent no. 154219 and consists in that the metal body formed from a slotted platinum-iridium tube, a web (bracket) and a solder tube is replaced by a bracket made of a solid metal, for example made of 20% platinum-iridium or another metal with approximately the same coefficient of expansion, with lateral widenings, which enable the connection with the neighboring teeth. On this massive piece of metal is a base or core. Porcelain mass with a coefficient of expansion which allows it to be burned onto the metal piece without bubbles or cracks, burned on, which is then burned over with a colored porcelain.
This creates a finished individual pontic, which can be easily processed without riveting, plating, etc. and soldered to one or more pontics, crowns or inlays and other supporting points.
This also gives the practitioner, who is not offended by the higher price that the massive platinum-iridium bar with its metal pieces on the side, the possibility of simply producing a full-fledged pontic without any manipulation.
