Hocera ST Multilayer Zirconia Block
VITA 16 Shades | Reliable Solution for Long Bridges and Full-Arch Restorations
Hocera ST Multilayer Zirconia Block is designed for dental laboratories that require both esthetic reliability and mechanical stability. In modern CAD/CAM workflows, laboratories must balance strength, translucency, and production efficiency. Therefore, Hocera developed this material based on a 4Y-TZP zirconia formulation to meet those demands.
As a result, Hocera ST Multilayer Zirconia supports predictable outcomes in long-span bridges and full-arch restorations. At the same time, it helps laboratories reduce manual processing steps and maintain consistent quality across cases.
Pre-Dyed Gradient Technology for Predictable Aesthetics
Unlike conventional mono-layer zirconia, Hocera ST Multilayer Zirconia uses VITA 16 pre-dyed gradient technology. This structure creates a natural chroma transition from cervical to incisal areas. Consequently, restorations appear more lifelike without additional staining.
Specifically, the cervical zone features higher chroma and density, which enhances depth. Meanwhile, the incisal zone incorporates a patented blue-gray layer that mimics natural enamel. As a result, the common “white-out” effect is effectively avoided.
Because the color gradient is integrated during manufacturing, laboratories can eliminate external staining. In practice, this saves approximately 15–20 minutes per unit and improves shade consistency after sintering.
Bio-Mimetic Optical Performance
In addition to its gradient structure, Hocera ST Multilayer Zirconia offers biomimetic optical properties. With a translucency of 43%, it allows light transmission similar to natural enamel. Therefore, restorations demonstrate improved depth and vitality, especially in anterior cases.
Furthermore, controlled opalescence enhances visual integration with adjacent teeth. According to CIELab verification, the material achieves up to 98% natural tooth color match. Consequently, laboratories can deliver esthetic results with minimal manual adjustment.
Mechanical Strength for Long-Span Restorations
Although translucency is enhanced, mechanical reliability remains a core focus. Hocera ST Multilayer Zirconia provides a flexural strength of up to 1200 MPa, which is essential for multi-unit restorations.
As a result, the material is suitable for 3–14 unit bridges and full-arch prosthetics. Moreover, it performs reliably in posterior load-bearing areas. The dense microstructure helps reduce micro-crack formation, which improves long-term durability.
In addition, optimized sintering stability supports consistent performance under high masticatory forces. Therefore, laboratories can confidently use the material in demanding clinical indications.
Streamlined CAD/CAM & Laboratory Workflow
From a production perspective, Hocera ST Multilayer Zirconia is optimized for digital CAD/CAM workflows. It is fully compatible with Roland and Ivoclar CAD/CAM systems, which simplifies integration.
Notably, the material supports zero calibration milling. Consequently, setup time is reduced and milling accuracy is improved. During sintering, shrinkage deviation remains within ±0.02%, ensuring dimensional stability.
Because of its excellent machinability, the material produces precise margins and smooth surfaces. As a result, laboratories achieve faster throughput and more consistent results across different disc sizes.
Clinical Indications
Hocera ST Multilayer Zirconia is suitable for a wide range of restorative applications. These include:
-
Full-arch prosthetics
