Description
Aufbrenntemperatur unter der Schmelz- bzw. Solidustemperatur der metallischen Pulverzusätze liegt. Bewährt haben sich Aufbrenntemperaturen zwischen 600 und 11000C und Aufbrennzeiten zwischen 0,5 und 10 Minuten. Die Goldschichten verbinden sich unter diesen Bedingungen mit allen gängigen Aufbrennlegierungen auf der Basis Gold-Platin-Palladium-Silber, Gold-Silber, Gold-Palladium, Nickel-Chrom, Kobalt-Chrom und Kobalt-Palladium zu einem unlösbaren Verbund. Die erfindungsgemäßen goldhaltigen Präparate sind damit für alle edelmetallhaltigen und edelmetallfreien Aufbrennlegierungen geeignetFiring temperature is below the melting or solidus temperature of the metallic powder additives. Firing temperatures between 600 and 1100 0 C and firing times between 0.5 and 10 minutes have proven to be effective. Under these conditions, the gold layers bond to all common bonding alloys based on gold-platinum-palladium-silver, gold-silver, gold-palladium, nickel-chromium, cobalt-chromium and cobalt-palladium to form an indissoluble bond. The gold-containing preparations according to the invention are therefore suitable for all bonding alloys containing and without precious metals.
Die so hergestellte Zwischenschicht bewirkt eine sehr gute Verankerung der Keramikschicht mit dem metallischen Kronen- oder Brückenteil. Hierzu eignen sich eile is bekannten dentalkeramischen Massen Biegeversuche an keramikverblendeten Legierungsblechen, die mit einer Zwischenschicht aus einem erfindungsgemäßen Goldpräparat überzogen waren, zeigten, daß bei gewaltsamer Absprengung der Keramikschicht vom Metall der Bruch in der Keramik selbst erfolgt Eine Trennung der Zwischenschicht von der Aufbrennlegierung bzw. von der Keramik konnte in keinem Fall beobachtet werden.The intermediate layer produced in this way ensures very good anchoring of the ceramic layer to the metal crown or bridge part. All known dental ceramic materials are suitable for this. Bending tests on ceramic-faced alloy sheets that were coated with an intermediate layer made of a gold preparation according to the invention showed that if the ceramic layer is violently detached from the metal, the fracture occurs in the ceramic itself. A separation of the intermediate layer from the bonding alloy or from the ceramic could not be observed in any case.

Ceramic bonding alloys in dental technology before 5 On the other hand, the importance of sufficient interlocking between the metallic ceramics and the dental ceramics for a good bond has long been known for veneering with ceramic masses consisting of gold powder, an adhesive and a binding agent made of one or more organic solvents and one or more resin coatings. The proportion of the so-called physical bond depends very strongly on the size, shape and roughness of the surface to be bonded to the ceramic.
From DE-OS 25 25 274 it is known to use preparations which, in addition to gold powder and a flux, also contain porcelain and zirconium oxide powder and 1 to 20% by weight of a metal powder as an adhesive, the particle size of which is larger than that of the gold powder used and which, however, leads to an unaesthetic grey-white layer when fired onto the firing alloy.
melting temperature is higher than that of gold. The aim of the invention was therefore to produce gold-containing
