Zir-X Zirconia Block -ST (Super Translucent)

Zir-X Zirconia Block – ST (Super Translucent)

Zir-X ST (Super Translucent) Zirconia Block is a high-performance CAD/CAM milling block designed for strong, esthetic, and long-lasting dental restorations. It features a natural white shade and develops a translucent, enamel-like appearance after sintering (baking).

Manufactured from high-purity zirconia ceramic, Zir-X offers excellent strength, fracture toughness, and wear resistance. It is suitable for both CAD/CAM and manual systems, delivering consistent results with high permeability and low thermal conductivity.

Key Features

• Super translucent finish after sintering
• Natural white color
• High hardness and wear resistance
• High fracture toughness (resistant to cracking)
• Low thermal conductivity
• Excellent biocompatibility
• Resistant to staining
• No metal base required

Compositions

• ZrO₂ (Zirconium Dioxide) + HfO₂ (Hafnium Dioxide) + Y₂O₃ (Yttrium Oxide) ≥ 99%
• Y₂O₃: 4.5% – 6.0%
