Zir-X Zirconia Block -ST (Super Translucent)

ZIR-X is a circular shaped block made up of Zirconia and Ceramic. It consist of high strength, excellent permeability, low thermal conductivity, and color aesthetic repair effect that is suitable for CAD/CAM system and manual system.

COMPOSITIONS:

• ZrO2(zirconium dioxide) + HfO2(Hafnium dioxide)+ Y2O3(Yttrium oxide) ≥ 99%
• Y2O3:4.5%;~6.0%
• Al2O3(Aluminum oxide) ≤ 0.2%
• Other Oxides ≤0.4%

ADVANTAGES

• Can be easily modified, reshaped and recolored. 
• Resemble natural tooth enamel due to their color and translucence.
• Do not require a metal base.
• Do not require as much of the original tooth be removed as with other types of crowns.
• No irritation.
• Good Bio-Compatibility.
• Resist staining better than acrylic or composite ceramic crowns.
• Low thermal conductivity.
• Hot and cold changes do not stimulate the pulp.
• Extremely Durable

FABRICATION OF ZIR-X

• ZIR-X are available in narrow size blocks sent to laboratories. 
• It is milled into single unit copings or multiple- unit fixed bridge frameworks.
