ST White

The ICERA ST White is a premium super translucent white monochromatic dental zirconia block engineered to deliver consistent quality, exceptional mechanical reliability, and excellent aesthetic versatility in a single disc. Through advanced manufacturing technology and refined raw material formulation, the ST White achieves a rare combination of ultra-high flexural strength (1250 MPa), superior anti-aging performance, and pleasing translucency (43%) — making it one of the most balanced and dependable monochromatic zirconia options available for daily laboratory production.

The ST White is a uniform white-colored zirconia disc designed as a flexible, high-strength foundation for custom-shaded restorations. Unlike pre-shaded or multilayer zirconia, the ST White provides a clean, neutral starting point that allows technicians to apply their preferred coloring liquids and staining systems to achieve any target shade. With its 1250 MPa strength and 43% translucency, the ST White is ideal for laboratories seeking a workhorse zirconia that performs reliably across a wide spectrum of clinical indications — from full-contour single crowns to demanding screw-retained implant bridges. Available in 98mm, 95mm, and 92×75mm diameters with thicknesses from 12mm to 25mm, the ST White accommodates virtually every CAD/CAM milling system on the market.

1. Ultra-High Flexural Strength (1250 MPa) With 1250 MPa of flexural strength, the ST White is one of the most mechanically robust monochromatic zirconia blocks in the ICERA family. This high-strength profile makes it suitable for the most demanding clinical scenarios, including long-span bridges, screw-retained implant restorations, and high-load posterior cases.
2. Superior Anti-Aging Performance The ST White delivers exceptional resistance to low-temperature degradation (LTD), with monoclinic phase content remaining below 15% even after accelerated aging tests. This means the ST White preserves its strength, translucency, and clinical performance over years of intraoral use — providing peace of mind to both clinicians and patients.
3. Stable, Consistent Quality Manufactured with strict process control and rigorous batch-by-batch quality testing, the ST White delivers exceptionally stable performance across every disc. Laboratories can rely on consistent milling behavior, predictable sintering shrinkage, and uniform final-restoration quality — every single time.
4. Excellent Translucency (43%) The ST White achieves a balanced 43% translucency that captures natural optical depth without sacrificing strength. Restorations milled from the ST White display realistic light transmission and depth — producing aesthetic results that satisfy both patient expectations and clinician standards.
5. Maximum Shade Customization Flexibility The neutral white base of the ST White provides complete creative freedom for technicians to apply custom coloring liquids, staining systems, and characterization techniques. This makes it an ideal foundation for laboratories with established shading workflows or for cases requiring precise custom shade matching.
6. Outstanding Density and Purity A post-sintering density of ≥6.0 g/cm³ produces a dense, pore-free microstructure that resists fracture, prevents staining penetration into unintended areas, and maintains shade stability over years of clinical use.
7. Excellent Biocompatibility & Safety With Grade 0 cytotoxicity, radioactivity below 0.1 Bq/g, and chemical solubility below 100 μg/cm², the ST White is fully safe for permanent intraoral use, even in patients with sensitive oral tissues.
8. Predictable Coloring Behavior The uniform microstructure and consistent porosity of the ST White ensure that coloring liquids absorb evenly and predictably — producing reliable, repeatable shade reproduction across every batch.
9. CAD/CAM Optimized Uniform pre-sintered density delivers smooth milling, sharp margin definition, extended bur life, and predictable sintering shrinkage for accurate restoration fit on the most demanding cases.

The ICERA ST White is engineered for a wide range of restorative indications:
・Inlays and onlays - durable aesthetics with custom shade flexibility
・Copings (inner crowns) - precise marginal fit with strong support
・Coping bridges (inner crown bridges)
・Full-contour crowns - anterior and posterior
・Full-arch bridges - with custom shade work across multi-unit cases
・Half-arch bridges
・Screw-retained implant bridges
・Implant-supported single crowns
・Implant restorations - where strength and stability are paramount

The ST White represents ICERA's commitment to providing dental laboratories with a dependable, high-strength workhorse zirconia that performs reliably across the broadest range of clinical cases. Manufactured from Sinocera raw zirconia powders using advanced CIP (cold isostatic pressing) technology, every ST White disc is engineered to deliver consistent quality, superior anti-aging performance, and predictable clinical results. Each batch undergoes rigorous quality testing covering flexural strength, translucency, density, aging resistance, biocompatibility, and microstructural uniformity.

For dental laboratories seeking a stable, strong, and versatile zirconia foundation for custom-shaded restorations — and for clinical cases where long-term durability matters most — the ICERA ST White is the smart choice. Its ultra-high strength, exceptional anti-aging performance, and pleasing translucency make it an ideal everyday solution for laboratories that refuse to compromise on quality or reliability.
