CASTING-ON PROCESS FOR MANUFACTURING DENTAL PROSTHESES AND PRIMARY PART FOR SAID PROCESS

摘要

In a casting process for making dentures, wherein a metal secondary part is cast onto a metal primary part, a primary part consisting of a metallic alloy forming an oxide can be used if the casting surface is combined with a reducing metalloid before casting. For this purpose, boron, silicon or phosphorus may be diffused into the surface network of the primary part. A primary part, which consists of a dental alloy forming an oxide and is suitable for this type of casting process, contains boron and / or silicon and / or phosphorus in its casting surface.
