Definitions
- the invention relates to an alloy for dental purposes, in particular as a ceramic bonding alloy.
- the object of the invention is to reduce the precious metal content of such alloys. This is achieved by an alloy according to the claims, from which it can be seen that the noble metal content could be significantly reduced.
- the invention is explained below by giving an example, it has the following composition:
- This alloy is suitable for the production of parts for dentures by a casting process. It is extremely corrosion-resistant and therefore particularly well tolerated by the body.
- the corrosion behavior is demonstrated by the following measurement results on the alloy.
- the alloy is suitable for the production of the finest castings.
- the wire thickness can be 0.1 mm with simultaneous complete volume filling.
- the alloy has a small and low solidification interval from 1360 ° to 1380 °. It can therefore be poured using simple heating devices while minimizing wear on devices and crucible materials. Signs of segregation are minimal due to the narrow solidification interval.
- Dental porcelain (veneers) can be fired onto the alloy.
- the porcelain layers can also be applied in layers, they adhere permanently and firmly.
- the connection between porcelain and alloy is complete.
- the adhesion between the porcelain and the alloy is produced by an intermediate oxide which is formed from the alloy. The adhesion is so strong that no chipping takes place in the process of quenching an alloy porcelain portion from the baking temperature to room temperature. When an alloy porcelain part is subjected to impact loads at the tips and edges with force impacts of 20 gms -1, the porcelain covering does not flake off from the alloy part.
- the porcelain can be applied in layers and sintered up to temperatures up to 950oC.
- a thin, uniform and non-porous oxide layer forms on the surface of a part made of the alloy, so that high-temperature corrosion attacks do not change the alloy, in particular the material does not become brittle, so that fine wires or fine sheet metal parts can be cast.
