It is a metalloceramics especially suited to all types of conventional alloys with a thermal expansion coefficient in the range of 13.8 to 14.9 × 10-6 K-1 (25-500 ° C), regardless of whether they contain silver, have a reduced gold content or are based on palladium and also for veneered crowns on base metal alloys and electroplated crowns. Its properties are, feldspar ceramics with a firing temperature below 900 ° C., precisely matched thermal expansion coefficients, excellent physical and optical properties, optimal contractility, harmonized shades enabling the right color selection and restoration of the aesthetics of natural teeth, adapted to sintering techniques in combination with GC Initial MC / LF connector paste.
