ST-C Monolithic Zirconia Block , 1100MPa Strength , 16 Shade Options for Full-Contour Dental Crowns
ST-C Zirconia Block , Standard Translucency , Multi-Shade Economical Solution for Dental Crowns
The ST-C Zirconia Block delivers exceptional value for high-volume dental laboratories, combining ISO-compliant strength with optimized shade versatility. Engineered for posterior restorations and deep-shade applications, this monolithic zirconia eliminates staining steps with pre-shaded efficiency. Its balanced translucency (standard grade) ensures natural aesthetics in molar regions, while exceeding ISO 6872 Class 4 strength thresholds for 3-unit bridges.
Key Characteristics
• Cost Efficiency: Ideal for high-throughput labs, reducing production costs without compromising quality.
• Shade Flexibility: Comprehensive shade range covers deep hues (e.g., B3-B4, C3-C4, D2-D4) where high translucency provides diminishing returns.
• Bio-Safe Composition: 0-level cytotoxicity and <0.1 Bq/g radioactivity align with global medical safety standards.
• Chairside Efficiency: Pre-shaded blocks skip staining/drying steps (Page 14), shortening production time by 30%.
Technical Specifications
Property | ST-C Value |
---|---|
Flexural Strength | 850 MPa (Typical) |
Translucency (1.0mm) | Standard Grade |
Fracture Toughness | ≥5.0 MPa·m¹ᐟ² |

Clinical Advantages
Deep-Shade Mastery: Outperforms high-translucency materials in dark hues (A4-D4) with superior opacity.
Milling Precision: Pre-sintered density of 3.15±0.05 g/cm³ ensures smooth CAD/CAM processing.
Long-Term Stability: <15% monoclinic phase after aging resists low-temperature degradation.
Zero Imaging Interference: Fully radiolucent for unobstructed X-ray/CT diagnostics.
