1. What Is a Pre Shaded Zirconia Block?
A pre-shaded zirconia block is a high-strength ceramic material used in CAD/CAM dental restorations. Unlike standard white zirconia, this type of block already contains natural tooth color shades (A1–D4 or multilayer tones), which reduces manual staining time and ensures color consistency. It is widely used for monolithic crowns, bridges, and implant cases.
2. Advantages of Pre Shaded Dental Zirconia Block Materials
No Staining Needed – Save lab time with in-block coloring.
Natural Shade Matching – From HT to UT series, offering vivid results.
Excellent Strength & Aesthetics – Up to 1200 MPa strength and good translucency.
Consistent Performance – Minimal shrinkage, great marginal fit.
Compatible with Open CAD/CAM Systems – Easy to integrate.
3. Material Composition of Pre Shaded Zirconia Block
| Component | Content | Function |
|---|---|---|
| ZrO₂ + HfO₂ + Y₂O₃ | ≥99% | Core structure; provides strength and stability. |
| Y₂O₃ | 4.5–6.0% | Stabilizes structure; improves fracture resistance. |
| Al₂O₃ | <0.15% | Enhances sintering and wear resistance. |
| Coloring Pigments | Trace amount | Gives natural tooth color; consistent shading. |
4. Applications of Pre Shaded Zirconia Blocks
Monolithic crowns and bridges
Full contour restorations
Implant abutments
Inlays, onlays, and veneers
Full-arch implant prosthetics
We offer 4 pre shaded zirconia series:
| Series | Translucency | Strength | Best For |
|---|---|---|---|
| HT | Low | Up to 1200 MPa | Posterior crowns, long-span bridges |
| ST | Medium | 1100 MPa | Crowns and bridges with better esthetics |
| SHT | High | 900–1000 MPa | Anterior teeth, monolithic restorations |
| UT | Ultra High | ~700 MPa | Front teeth, veneers, cosmetic cases |
5. Sintering Curve for Pre Shaded Zirconia Block
Our recommended sintering schedule ensures full strength and color uniformity.
Typical curve (for ST/SHT):
Heat rate: 8–10 °C/min
Holding temperature: 1500–1530°C
Holding time: 2 hours
Total time: ~6–8 hours
(Custom sintering curves available upon request.)
6. Manufacturing Process of Pre Shaded Zirconia Block
Powder mixing and pigment infusion
Cold isostatic pressing (CIP)
