Vsmile HT Dental Zirconia Discs: High-Strength Frameworks for Predictable Posterior Restorations

 

Highlight Feature:

The Vsmile HT (High Translucency) Zirconia Disc is a high-strength (1350 MPa), yttria-stabilized framework material engineered for durable posterior single-unit crowns, long-span bridges, and abutments, providing a reliable block-out effect for discolored stumps and titanium bases. Seamlessly compatible with your open CAD/CAM system for unparalleled milling efficiency.

 

1. Product Introduction: The Foundation of Durable Dentistry (Expertise & Experience)

As a leading dental lab, you demand materials that combine unwavering strength with predictable processing. The Vsmile HT Dental Zirconia Disc is your solution. Crafted from high-purity Y-TZP Zirconium Oxide powder using advanced Cold Isostatic Pressing (CIP) technology, the HT block is engineered for superior density and minimal, consistent shrinkage.

 

This disc is specifically designed for restorations where high strength is critical, making it the workhorse for posterior crowns and multi-unit bridges. While offering high flexural strength, its controlled opacity (approx. 37% Translucency) provides an essential block-out effect, effectively masking metal substructures or severely discolored tooth preparations-a common challenge in restorative dentistry. Integrate Vsmile HT into your digital workflow for superior efficiency, longevity, and clinical results that build trust with your clinicians.

 

 

2. Why Choose Vsmile HT? Core Benefits

 

Feature	Advantage	Benefit
Ultra-High Flexural Strength (1350 MPa)	High resistance to fracture and chipping.	Eliminates Remakes and restoration failure, saving your lab time and material costs, especially for load-bearing posterior bridges.
Controlled Opacity (Approx. 37% Translucency)	Ideal high opacity value for block-out effect.	Guarantees Aesthetic Success by perfectly masking dark, discolored stumps or hybrid abutments on titanium bases.
Superior Milling Performance	Optimal density and composition.	Reduces Bur Wear and allows for finer margins and surface quality, ensuring a perfect fit and maximizing the lifespan of your milling burs.
Wide CAD/CAM Compatibility	Available in 98mm (Open System), 95mm (Zirkonzahn), and 92*75mmmm (Amann Girrbach) formats.	Seamless Integration with all major dental milling machines (Roland, Wieland, VHF, Yenadent, etc.), requiring no workflow adjustments.
Cold Isostatic Pressed (CIP) Quality	Uniform density and low, consistent shrinkage.	Ensures Pinpoint Accuracy of the final restoration size and fit after sintering, minimizing post-milling adjustments.

5. Frequently Asked Questions (FAQ) (Experience & Trustworthiness)

 

Q1: What is the main advantage of Vsmile HT over ST (Super Translucency)?

A: Vsmile HT zirconia block is engineered for maximum strength (1350 MPa) for durable posterior and long-span restorations, combined with enough opacity (37%) to effectively mask dark preparation colors and metal abutments. ST zirconia block offer higher aesthetics (higher translucency) but typically lower strength 1200Mpa, making HT the choice for high-stress areas.

 

Q2: Is the Vsmile HT Zirconia Disc compatible with my existing CAD/CAM system?

A: Yes. Vsmile HT discs are designed with wide compatibility, available in the popular 98mm open system, the 95mm Zirkonzahn format, and the 92-75mm Amann Girrbach (AG) format. They are compatible with virtually all open dry-milling machines, ensuring a seamless fit into your lab's current workflow.

 

Q3: Does Vsmile HT come in pre-shaded options? A: Yes. The Vsmile HT is available in a pure white disc (ideal for custom brush/dipping infiltration) and a separate HT Preshaded version, which offers VITA 16 shades for a faster, pre-colored framework solution.

 

Q4: How does the CIP technology benefit my restorations?

A: Cold Isostatic Pressing (CIP) ensures the zirconia powder is compacted uniformly, resulting in a blank with consistent density throughout. This prevents warping, non-uniform shrinkage, and internal stress, delivering a final restoration with pinpoint margin accuracy and a precise fit.
