Description

Verfahren zur Herstellung von zahnärztlichen Edelmetallprothesen. Das Patent 452 869 betrifft ein Verfahren zur Herstellung von billigen, korrosionsfreien zahnärztlichen Edelmetallprothesen unter Verwendung einer Alphamischkristalle bildenden Edelmetallegierung, die nach Fertigstellung bei sicherem elektrischen Kontakt in einer erhitzten Chromoxydlösung, d. h. ohne eine andere Hilfszwischenschicht aus Metall mehrere Stunden gleichmäßig hochglänzend verchromt werden, so daß sie gegenüber den verschiedenartigen schädlichen Beeinflussungen der Säuren und elektrolytischen Strömungen des Mundes widerstandsfähig bleiben.Process for the production of dental precious metal prostheses. The patent 452 869 relates to a method for the production of cheap, corrosion-free Dental precious metal prostheses using an alpha solid solution forming Precious metal alloy, which after completion with safe electrical contact in a heated chromium oxide solution, d. H. without another auxiliary intermediate layer Metal can be chromed evenly to a high gloss for several hours so that they are opposite the various harmful influences of acids and electrolytic Mouth currents remain resilient.

Nachdem aber die weißblaue Platinfarbe der so hergestellten Prothesen o. dgl. vielfach dem Empfinden und der Gewohnheit vieler Patienten nicht entspricht, ist in nachstehend beschriebenen Verfahren ein Ausweg gefunden.But after that the white-blue platinum color of the prostheses manufactured in this way or the like often does not correspond to the feelings and habits of many patients, a way out is found in the procedure described below.

Gegenstand der Erfindung ist eine Verbesserung und weitere Ausgestaltung diesfs Verfahrens, welche darin besteht, daß die beim Öffnen des Mundes sichtbar werdenden Flächen der aus der Alphamischkristalle bildenden Feinsilberlegierung bestehenden Ersatzteile mit einer Goldschicht, die aus einer ebensolche Mischkristalle bildenden Goldlegierung oder einem hochkarätigen Goldlot besteht, überzogen oder überschwemmt werden; darauf wird diese Außenschicht zwecks Ausführung der Verchromung vor der Berührung mit der Chromoxydlösung durch Auftragen einer Klebewachsschicht geschützt, so daß das Gold mit der Badflüssigkeit nicht in Berührung kommt. Die Verchromung geht dann gemäß der im Patent 452869 geschilderten Weise vor sich. Werden die Stücke dem Bade entnommen, so wird das Klebewachs in Sodawasser abgekocht und das Ganze poliert. Die fertigen Teile entsprechen im Munde des Trägers vollkommen den massiven Vollgoldprothesen, wie es viele Patienten verlangen, wohingegen sich der Anschaffungspreis sehr verringert.The object of the invention is an improvement and further development of this method, which consists in that the surfaces of the fine silver alloy consisting of the alpha solid solution, which become visible when the mouth is opened, with a gold layer consisting of a gold alloy forming such solid solution or a high-carat gold solder, become covered or flooded; then this outer layer is protected from contact with the chromium oxide solution by applying a layer of adhesive wax so that the gold does not come into contact with the bath liquid for the purpose of chrome plating. The chrome plating then proceeds as described in patent 452869. If the pieces are removed from the bath, the sticky wax is boiled in soda water and the whole thing is polished. In the mouth of the wearer, the finished parts correspond perfectly to the massive solid gold prostheses, as many patients demand, whereas the purchase price is very much lower.
