HT White Zirconia Blocks 1400 MPa High Strength 98.5mm For Dental Bridges Crowns
Product Introduction
The HT White Zirconia Block is engineered for ultimate strength and reliability in demanding dental restorations. With an exceptional flexural strength of 1400 MPa, it is the ideal choice for long-span bridges, full arches, and other restorations where maximum durability is critical. This block provides a 40% translucency and a pure white color, ensuring a solid foundation for layered restorations or a clean, opaque base for high-chroma cases.

FAQ
1. What is the primary use of the HT White Zirconia Block?
Its primary use is in fabricating long-span dental bridges (exceeding 3 units), full-arch frameworks, and crowns in areas of high masticatory stress, where its 1400 MPa strength provides essential safety and durability.
2. Is this block suitable for monolithic anterior restorations?
While it is extremely strong, its 40% translucency and white color make it less ideal for highly aesthetic monolithic anterior cases compared to our multilayer series. It is best used as a strong core material in such areas.
3. Why is the sintering temperature higher for this block?
The higher final sintering temperature (1530°C) is crucial for achieving the highest density and optimal crystalline structure required to attain the 1400 MPa flexural strength. Please follow the provided sintering program precisely.
