Designed for high-stress posterior regions, the SHT Zirconia Block delivers 1000MPa flexural strength – sufficient for 4+ unit bridges. Its 5.7 MPa·m¹ᐟ² fracture toughness outperforms conventional zirconia (industry average: 4.5-5.2), resisting chipping under 300N occlusal forces. Accelerated aging tests confirm <5% monoclinic phase retention after 20-year simulation.
Engineering Breakthroughs
Y₂O₃ Stabilization: 7.0-7.8% yttria content prevents low-temperature degradation
Thermal Stability: CTE (10.5±0.5)×10⁻⁶/K matches natural dentition
Impurity Control: <0.15% Al₂O₃ ensures crack resistance
