Ceramic dental material Leo

alloyporcelaincasting

Leo is a reduced-gold ceramic alloy, suitable for conventional metal-ceramics. The good flow properties during casting and the high heat resistance allow for a wide range of indications. Indications* Inlays Onlays, ¾ crowns, crowns Telescope crowns, conus crowns Bridges Wide-span bridges Cast posts /cores, bars, attachments Partial dentures Technical Data Composition (%): - Au 45.0 | Pd 41.0 | Ag 6.0 | Sn 2.2 | In 3.4 | Ga 1.8 | Re <1.0, Ru <1.0, Li <1.0 ISO - 22674:2016 ADA Class: - High Noble Type / Color: - 4 / White Density (g/cm³) - 13.5 Melting Range (Solidus/Liquidus): - 1225 - 1315 °C Elastic Modulus (GPa): - 140 - Porcelain Fired Hardened Vickers Hardness: - 190 280 Tensile Strength (MPa): - 670 740 0.2% Proof Stress (MPa): - 450 540 Elongation (%): - 20 18 Advantages Good casting and flow characteristics High heat resistance Compatible with conventional metal-ceramics (e.g. IPS Style) Wide range of indications Tested biocompatibility
