The SHT Ultra-Translucent Zirconia Block redefines dental aesthetics with industry-leading 46% translucency – the highest in its class. Engineered for monolithic restorations, it combines 1000MPa flexural strength (exceeding ISO 6872 Class 5 by 25%) with exceptional light diffusion properties. Pre-sintered at 1500°C using CIP technology, each white block (98/95/92×75mm) maintains uniform density (3.15±0.05 g/cm³) for consistent milling. Compatible with 16/26 shade staining systems, it enables seamless color matching for natural-looking anterior and posterior crowns.
Key Innovations
Optical Superiority: 46% translucency at 1.0mm thickness – ideal for "invisible" margin designs.
Aging Resistance: <5% monoclinic phase after accelerated aging ensures decade-long stability.
Bio-Safety: 0-level cytotoxicity and <0.1 Bq/g radioactivity for patient safety.
Staining Flexibility: Compatible with dilution liquids for gradient color control.
