1. What is White Zirconia Blocks?

White zirconia block is a high-performance ceramic material used in the fabrication of dental restorations such as crowns, bridges, veneers, inlays and implant abutments, etc. Within the dental industry, it is common to refer to unstained zirconia block as white zirconia block, and pre-stained block as colored block, white zirconia block is relatively inexpensive, and it can be stained through the post-staining process to achieve the coloring, which is well known for its excellent strength, stability, and natural looking teeth. The blocks are mainly used in dental laboratories where they are milled using CAD/CAM milling machines and then sintered at high temperatures to achieve the final hardness and translucency.


2. Advantages of White Dental Zirconia Blocks Materials

  • High strength: Suitable for both anterior and posterior restorations, including long-span bridges.

  • Natural translucency: Closer to natural teeth in shade and brightness, especially in our ST, SHT, and UT series.

  • Biocompatibility: Safe and well-tolerated by gum tissue.

  • Stable performance: Minimal shrinkage, reliable in large-scale production.

  • Flexible applications: From monolithic crowns to layered restorations.

3. Material of White Zirconia Blocks

All our zirconia blocks are made from premium quality Yttria-stabilized zirconium oxide (3Y, 4Y, 5Y), carefully selected for dental applications. We strictly control powder particle size, purity, and homogeneity to ensure stable quality across all batches.

ComponentContentFunction
ZrO₂ + HfO₂ + Y₂O₃≥99%Forms the main structure, ensuring high strength and durability.
Y₂O₃4.5% – 6.0%Acts as a stabilizer to improve toughness and crack resistance.
Al₂O₃<0.15%Enhances sintering behavior and mechanical properties.
Other oxides<0.15%Maintains uniformity and quality without affecting translucency.




4. Application of White Zirconia Blocks

Our blocks are suitable for:

  • Crowns & bridges

  • Veneers & inlays

  • Implant-supported abutments

  • Customized full-arch restorations

  • Temporary and permanent dental prosthetics

We offer four series to meet different clinical needs:

  • HT (High Strength): Ideal for long-span bridges and posterior teeth.

  • ST (Super Translucent): Balances strength and esthetics, good for posterior crowns.

  • SHT (Super High Translucent): Best for anterior restorations with high esthetic demand.

  • UT (Ultra Translucent): Maximum translucency, designed for top-level esthetic cases.

5. Sintering Curve of White Zirconia Blocks

Each zirconia series has its recommended sintering curve. A typical example:

  • Heating rate: 8–10°C/min

  • Holding temperature: 1500–1550°C (depends on block type)

  • Holding time: 2 hours

  • Cooling rate: Natural cooling

We provide detailed sintering curves with every shipment for best results.


6. Process of White Zirconia Blocks

  1. Design: Scan the impression and design restoration via CAD.

  2. Milling: Choose the appropriate zirconia block size and type, mill with CAM machine.

  3. Drying: Remove moisture before sintering.

  4. Sintering: Heat treatment as per recommended curve.

  5. Coloring (optional): Pre-shaded or dipped depending on desired effect.

  6. Finishing: Polish, glaze or layer porcelain as needed.
