Pre Shaded Zirconia Block Offering Biocompatible Material and Excellent Optical Behavior for Natural Dental Restorations
✅ Optimized English Version — ST Preshaded Zirconia Disc
High-Translucency Aesthetic Zirconia for Natural, Long-Lasting Restorations
Product Description
The ST Preshaded Zirconia Disc is specially developed for high-esthetic dental restorations, offering an ideal balance of translucency, strength, and color accuracy.
Pre-shaded in natural VITA tooth shades, it eliminates the need for manual staining, simplifies the workflow, and ensures excellent shade consistency in every restoration.
With a stable microstructure and outstanding optical performance, the ST series is suitable for both anterior and posterior indications, delivering restorations that closely reproduce the brilliance, depth, and vitality of natural enamel.
Key Advantages
1. Accurate Pre-Shaded Color System
Available in full VITA 16 shades, providing predictable and uniform color results without additional staining or infiltration steps.
2. Optimal Balance of Strength & Translucency
With a flexural strength of 1100 MPa and translucency up to 43%, ST zirconia ensures excellent mechanical reliability while achieving superior esthetic performance.
3. Wide Range of Indications
Ideal for:
-
Single crowns
-
Bridges
-
Inlays & onlays
-
Veneers
-
Full-contour restorations
4. Proven Biocompatibility
A safe, hypoallergenic zirconia material suitable for long-term intraoral use and high clinical reliability.
5. Manufacturer Advantage
As a professional zirconia manufacturer with 17+ years of experience, Audental produces over 60,000 discs per month under strict ISO 13485 quality management.
Factory-direct production ensures stable quality, reliable supply, and competitive pricing.
Processing Instructions
1. Milling
Mount the zirconia disc into your CAD/CAM milling machine.
Fully compatible with most open systems (98 / 95 / 92 mm) for precise and efficient machining.
2. Sintering
-
Final sintering temperature: 1530 °C
-
Heating rate: ≤ 8 °C / min
-
Allow the restoration to cool naturally inside the furnace to room temperature
This controlled cooling process prevents deformation, internal stress, and surface micro-cracks.
3. Final Finishing
Proceed with adjustment, polishing, or glazing as required.
The pre-shaded design significantly reduces — and in many cases eliminates — additional coloring steps, improving efficiency and consistency.
