dental material zirconium blank zirconia disc

 

Dental zirconia discs, also known as zirconia blocks, are advanced materials used in CAD/CAM dental systems to create highly durable and aesthetic dental restorations. Made from high-quality zirconium oxide (ZrO2), these blanks are designed for the production of crowns, bridges, veneers, and other dental restorations.

Zirconia has excellent mechanical properties, including high flexural strength, fracture toughness, and wear resistance. For example, posterior crowns and bridges must withstand tremendous chewing forces. The material's biocompatibility ensures long-term safety in the mouth without causing adverse reactions.

In addition to strength, dental zirconia discs have excellent aesthetic qualities. They can be manufactured with different translucencies to closely mimic the natural appearance of teeth, especially in areas visible to others. These blocks can be matched to the patient's natural tooth color to blend seamlessly with the rest of the smile.

Works efficiently with CAD/CAM systems.

Manufacturing process:

Powder preparation: Zirconia powder is carefully processed to achieve a uniform particle size distribution. The powder is mixed with a stabilizer such as yttrium oxide and the mixture is then pressed into a preformed shape using a cold isostatic pressing process.

Sintering: After forming, the discs are sintered at high temperatures (between 1400°C and 1600°C) to achieve the required density and strength.
