A system for dental restorations comprising dental alloys for the manufacture of a substructure of the restoration and dental porcelains for coating the substructure. The porcelains have a relatively high thermal expansion coefficient, above 14.5 µm/m.°C, and a relatively low firing temperature, below 950°C. The alloys have adapted properties, a thermal expansion coefficient above 14.5 µm/m.°C and a solidus temperature of at least 1000°C. |
