Advantages

• Light oxide
• High temperatur strength for accurately fitting restorations
• CTE value is coordinated with conventional metal-ceramics for the layering and the press technique
• No long-term cooling necessary
• High strength values; thus optimally suitable for long-span restorations
• Suitable for bonding systems and veneering composites (e.g. SR Link / SR Adoro)

Indications

• Onlays,
• ¾ crown
• ceramic crowns
• crowns
• telescopic and conus crowns
• posts
• short- and long span bridges
• partial dentures
