HT White

The ICERA HT White is a premium high-strength white monochromatic dental zirconia block engineered for the most demanding restorative cases. Featuring ultra-high flexural strength, exceptional hardness, and superior opacity, the HT White is designed to handle long-span bridges, multi-unit reconstructions, and clinical scenarios where metal substructures or heavily discolored abutments must be perfectly masked. With its 1250 MPa flexural strength and refined microstructure, the HT White delivers the kind of dependable structural integrity that clinicians require for high-load, long-term restorations.

The HT White is a uniform white-colored zirconia disc that combines exceptional mechanical strength with outstanding masking capability. Unlike higher-translucency zirconia products that struggle to conceal underlying discoloration, the HT White's 39% translucency provides excellent opacity — making it the ideal choice for cases where the foundation must be hidden. Its strong 1250 MPa flexural performance makes it equally suitable for full-arch reconstructions, screw-retained implant bridges, and demanding posterior cases. Available in 98mm, 95mm, and 92×75mm diameters with thicknesses from 10mm to 25mm, the HT White accommodates virtually every CAD/CAM milling system on the market.

1. Ultra-High Flexural Strength (1250 MPa) The HT White delivers ultra-high flexural strength of 1250 MPa — placing it among the most mechanically robust monochromatic zirconia products available today. This extreme strength makes the HT White the preferred choice for long-span bridges, full-arch reconstructions, and any case where structural reliability cannot be compromised.
2. Superior Hardness In addition to flexural strength, the HT White exhibits outstanding hardness — providing exceptional resistance to wear, chipping, and surface degradation over years of intraoral function. This makes it especially well-suited for posterior cases and patients with strong occlusal forces or bruxism tendencies.
3. Outstanding Opacity for Metal Masking With 39% translucency, the HT White provides superior opacity that perfectly conceals underlying metal substructures, post-and-core foundations, and heavily discolored abutments. Where higher-translucency zirconia would allow shadows or discoloration to telegraph through, the HT White produces clean, uniform restorations with no visible substrate interference.
4. Excellent Anti-Aging Performance After accelerated aging tests, monoclinic phase content remains below 15%, demonstrating strong low-temperature degradation (LTD) resistance. The HT White retains its strength, hardness, and clinical performance throughout long-term intraoral service.
5. Outstanding Density and Microstructure A post-sintering density of ≥6.0 g/cm³ produces a dense, pore-free zirconia structure that resists fracture, prevents staining penetration, and maintains long-term color and structural stability. This dense microstructure is also a key contributor to the HT White's exceptional hardness and wear resistance.
6. Excellent Biocompatibility & Safety With Grade 0 cytotoxicity, radioactivity below 0.1 Bq/g, and chemical solubility below 100 μg/cm², the HT White is fully safe for permanent intraoral use, even in patients with sensitive oral tissues.
7. Reliable Foundation for Custom Shading The neutral white base allows technicians to apply custom coloring liquids and staining systems to achieve any target shade. This makes the HT White an excellent foundation for laboratories that maintain proprietary shading workflows.
8. CAD/CAM Optimized Despite its high strength, the HT White retains excellent millability thanks to its optimized pre-sintered density. Technicians benefit from smooth milling, sharp margin definition, extended bur life, and predictable sintering shrinkage — even on the most complex multi-unit cases.
9.  Predictable Sintering Performance Tightly controlled shrinkage tolerance ensures dimensional accuracy after sintering, delivering precise marginal fit and reducing rework on long-span bridges and full-arch frameworks.

The ICERA HT White is engineered for the most demanding restorative indications:
・Inlays and onlays - durable structural restorations
・Copings (inner crowns) - precise marginal fit with strong support
・Coping bridges (inner crown bridges) - strong substructures for layered restorations
・Full-contour crowns - posterior cases prioritizing strength
・Long-span bridges - including full-arch reconstructions
・Half-arch bridges
・Screw-retained implant bridges - high-strength frameworks
・Implant-supported single crowns
・Metal-masking cases - over post-and-core foundations or discolored abutments
・Bruxism cases - patients requiring exceptional wear resistance

The HT White represents ICERA's commitment to delivering uncompromising structural performance for the most demanding clinical cases. Manufactured from Sinocera raw zirconia powders using advanced CIP (cold isostatic pressing) technology, every HT White disc is engineered to deliver maximum strength, exceptional hardness, and reliable masking performance. Each batch undergoes rigorous quality testing covering flexural strength, density, aging resistance, biocompatibility, and microstructural uniformity.

For dental laboratories handling long-span bridges, full-arch implant cases, metal-masking restorations, or any clinical scenario where strength is paramount — the ICERA HT White is the dependable choice. Its ultra-high flexural strength, superior hardness, and outstanding opacity make it the workhorse zirconia for demanding restorative dentistry.
