HT Zirconia Disc – High Translucency | Aesthetic & Durable CAD/CAM Restorative Zirconia

The HT Zirconia Disc (High Translucency Zirconia) is a premium CAD/CAM-compatible dental restorative material designed for "high-aesthetic transparency + long-term stability." It is widely used for anterior esthetic restorations, full-arch crowns, and multi-unit bridges.

Available in 98mm, 95mm, and 71mm diameters with 10–25 mm thickness options, the disc features a universal edge-notch design for seamless compatibility with major 5-axis milling systems. This ensures efficient processing and high-precision digital workflows.

Manufactured from high-purity nano zirconia powder (≥99.5%) and stabilized with 3Y yttria, the material offers an ideal balance of translucency and mechanical strength-making it a preferred choice for dental labs producing high-quality restorations at scale.

The core advantages span four dimensions: high translucency, stable strength, easy compatibility, and proven safety.

 

1. High Translucency for Natural Esthetic Outcomes

Using nano zirconia particles (20–50 nm) and optimized crystal alignment, the material reduces light scattering and delivers a stable translucency of 45%–55%-matching the refractive behavior of natural enamel. Vacuum mixing guarantees uniform composition and prevents uneven translucency ("fake-tooth effect").

Advantages

Lifelike, Natural Esthetics
Translucency closely matches natural teeth, delivering enamel-like brightness and eliminating the "metal shadow" typical of PFM crowns. Restorations blend seamlessly with surrounding dentition.

Excellent Shade Coverage
Combines translucency with strong masking ability-suitable for tetracycline staining, fluorosis, and dark tooth bases. Clinical shade-matching accuracy increases by up to 80%.

Simplified Aesthetic Workflow
High native translucency reduces the need for extensive staining or glazing. Single-crown processing time can be shortened to under 3 minutes, supporting same-day restoration delivery.

2. Superior Mechanical Strength for Long-Term Durability

3Y-stabilized tetragonal zirconia and cold isostatic pressing result in a dense crystal structure (>6.05 g/cm³). The material benefits from transformation toughening, where tetragonal crystals shift to monoclinic under stress, absorbing impact and preventing crack propagation.

Advantages

Reliable High Strength
Flexural strength reaches 1000–1350 MPa, far exceeding the 200–300 MPa of human bite force. Posterior bridges (3–4 units) show a chipping rate <0.5%, well below industry averages.

Long-Term Stability
Excellent chemical inertness ensures no corrosion, aging, or degradation under oral pH cycling. Clinical service life exceeds 10 years, with an 8-year survival rate up to 95%.

Supports Minimally Invasive Dentistry
High strength allows the fabrication of ultra-thin veneers as thin as 0.08 mm, reducing tooth preparation and enabling micro-invasive or non-invasive treatments.
