1.What is ST Shaded Zirconia Block？

Honchon ST Shaded Zirconia Block is an ultra-translucent, pre-colored zirconia material designed to balance aesthetics and function in dental restorations. Through scientific material proportioning and precise coloring technology, the ST series ensures the strength of the restorations while giving them a more natural luster and color transition, which is suitable for a wide range of clinical applications.

2.Key features of ST Shaded Zirconia Block

Ultra-translucent: 43% light transmission, close to natural tooth enamel, for a more realistic light effect.

One-piece pre-coloring: natural gradient transition, avoiding artificial dyeing errors, stable and long-lasting color.

High strength support: Flexural strength up to 1100 MPa, meets the aesthetic needs of anterior teeth as well as supports a wide range of bridge restorations.

Good processing adaptability: adaptable to the mainstream CAD/CAM system in the market, smooth cutting, sharp and delicate edges after sintering.

3.core benefits of st shaded zirconia block

Enhanced restoration aestheticThe natural light scattering and transmittance effect makes the restorations still present soft and natural sense of light under different angles, which leads to higher patient satisfaction.

Simplified Processing

The pre-coloring process greatly reduces the time required for the technician to manually color the restorations, and at the same time reduces artificial color differences, improving the overall production efficiency.

Balancing Aesthetics and Strength

The strength range of 900-1100 MPa makes the ST block not only suitable for single crowns, but also can be safely applied to 3-4 units of small bridge restorations.

Consistent and Stable Quality Output

Strict testing of each batch ensures that light transmission, color consistency, and shrinkage are in line with international standards, helping dental technicians deliver high-quality work.

7.Frequently Asked Questions (FAQ)

What is the difference between ST shaded zirconia block and UT shaded zirconia block series?

The STshaded zirconia block series is slightly less translucent than the UT series, but is stronger and more suitable for short bridge repairs that require a balance of load bearing capacity.

Can STshaded zirconia block be used directly for rapid sintering?

Yes, Honchon offers two sets of sintering parameters, standard and rapid, which can be selected by the technician according to the actual needs.

Is the pre-shaded color of shaded zirconia block stable?

Yes, the pre-coloring process, in which inorganic and organic pigments are mixed with zirconia powder, results in a strong color that will not fade after high temperature sintering.
