Cad Cam dental Zirconia Blank zirconia disc

 

 

Cad Cam dental Zirconia Blank zirconia disc is a high-performance raw material for digital dental restoration design. Its main features and advantages are mainly reflected in the following aspects:

Raw material advantages

Components
ZrO2+HfO2+Y2O3	≥99%
Y2O3	≤6.0%
Al2O3	<0.5%
Other Oxides	<0.5%

 

 

Advanced Sintering Process

Zirconia is processed through high-temperature precision sintering, where zirconium oxide powder is densified into a uniform, compact grain structure.

Typical sintering performance:

Sintering temperature: 1450–1600°C
Final density: ≥ 6.0 g/cm³
Linear shrinkage: 20–25% (controlled within ±0.3%)
Product Characteristics
High Strength & Fracture Resistance

The material provides a flexural strength of 900–1200 MPa and excellent fracture toughness.
It is capable of withstanding long-term occlusal loads in posterior regions without deformation or structural failure.

Natural Aesthetic Performance

Multi-layer gradient control technology enables a smooth transition in color and translucency, simulating the enamel–dentin structure of natural teeth.
After sintering and polishing, the restoration shows balanced light transmission and natural depth perception.

Key optical parameters:

Translucency range: 40%–55% (model dependent)
VITA shade compatibility: A1–D4 / BL bleach series available
Stable Machinability for CAD/CAM

In the pre-sintered state, the material has controlled hardness suitable for digital milling.
It provides stable cutting behavior with low chipping risk and minimal tool wear.

Processing performance:

Milling precision: ±0.01 mm
Low edge chipping rate (<5% under standard milling conditions)
Compatible with 5-axis CAD/CAM systems
Excellent Biocompatibility

Made from high-purity medical-grade zirconia, the material contains extremely low metal ion content.
It is non-toxic, non-irritating, and does not trigger allergic reactions or gingival discoloration.
Suitable for long-term intraoral use.

Application Scope

Suitable for a wide range of all-ceramic restorations:

Single crowns
3–6 unit bridges
Full-arch restorations
Implant abutments and prosthetics

It provides a balance of strength and aesthetics for both anterior and posterior clinical cases.

Digital CAD/CAM Compatibility

Fully compatible with mainstream CAD/CAM workflows and 5-axis milling systems.
Ensures consistent accuracy in shape, marginal fit, and color reproduction.

Typical clinical precision:

Marginal fit accuracy: 20–50 μm
Repeatability deviation: ≤0.005 mm (system dependent)
