1. What is a CAD/CAM zirconia block?
CAD/CAM Zirconia Block is a high-strength, all-porcelain material for restorative dentistry, suitable for dental restorations processed by computer-aided design (CAD) and computer-aided manufacturing (CAM) techniques. The zirconia blocks are used for a wide range of restorative dental applications due to their excellent strength and aesthetic properties. They provide high-precision restorations, especially when used with equipment such as CEREC, inLab, Open Systems, Wieland/Zirkonzahn/Amann Girrbach, and many others.
Our factory provides three major categories: multi-layer, pre-colored, and white blocks, and 15 different types of CAD and CAM zirconia blocks. For more information, please click here to learn more about zirconia blocks.

2. Advantages of CAD/CAM Zirconia Block
High strength: Zirconia blocks have excellent flexural strength (up to 1350 MPa), which ensures the stability of the restoration over time during use.
Aesthetics: Provides high light transmission and blends perfectly with natural teeth, especially for anterior restorations.
Compatibility: Compatible with mainstream CAD/CAM systems (e.g., Wieland/Zirkonzahn/Amann Girrbach, etc.), adapting to different equipment needs.
Wear resistance: Zirconia blocks have high hardness and wear resistance to meet the needs of long-term use.
Pre-colored and multi-layer design: Pre-colored zirconia blocks and multi-layer zirconia blocks are designed to provide natural color transitions and reduce the need for artificial dyeing.
3. Material of CAD/CAM Zirconia Block
| Composition | Content |
|---|---|
| Zirconia and stabilizers (ZrO₂ + Y₂O₃ + HfO₂ + Al₂O₃) | ≥ 99.0% |
| Yttrium oxide (Y₂O₃) | 4.0% – 10.0% |
| Hafnium oxide (HfO₂) | ≤ 5% |
| Aluminum oxide (Al₂O₃) | ≤ 0.1% |
| Other oxides (Fe₂O₃, Er₂O₃, MnO) | ≤ 0.9% |
4. Application of CAD/CAM Zirconia Block
CAD/CAM Zirconia blocks are widely used in the following restorative dental applications:
Single crown restorations
Bridge restorations
Inlays and veneers
All-ceramic restorations
5. Sintering Curve of CAD/CAM Zirconia Block
The sintering curve is an important factor in optimizing the properties of zirconia materials. Typical sintering curves for CAD/CAM zirconia blocks are shown below:
Sintering temperature: 1530°C
Sintering time: Typically 1-2 hours, depending on the series of zirconia blocks.
Rate of temperature rise and fall: The recommended rate of temperature rise is 5°C/min, and the rate of temperature fall is 2°C/min to ensure the densification and homogeneity of the material.
6. Process of CAD/CAM Zirconia Block
Raw material preparation: Selection of high-quality zirconia powder and other additives to ensure the purity and stability of the material.
Molding: Zirconia powder is molded into the desired shape through a dry pressing process.
Sintering: The molded zirconia blanks are put into a sintering furnace and sintered at a high temperature to improve their strength and denseness.
Surface treatment: The surface is polished according to different needs to improve the aesthetic effect and processability.
