1. Antibacterial Properties: Supporting Oral Health

The surface of zirconia exhibits mild alkalinity, disrupting the pH balance of bacterial cell membranes and inhibiting the growth of common oral pathogens such as Streptococcus mutans and Porphyromonas gingivalis.
In addition, its dense surface (porosity <0.5%) minimizes bacterial adhesion sites, while its non-toxic composition ensures it does not irritate oral mucosa or trigger inflammatory responses.

Benefits:

① Reduced Bacterial Adhesion: Decreases bacterial accumulation on the restoration surface by more than 60%, reducing plaque formation and lowering the risks of caries and periodontal disease.
② Better Oral Health: Minimizes restoration-related infections (e.g., marginal gingivitis), especially beneficial for patients with poor oral hygiene.
③ Excellent Biocompatibility: Meets ISO 10993 biocompatibility standards, with no risk of allergy or cytotoxicity. Suitable for most patients, expanding clinical treatment coverage.

2. Excellent Biocompatibility: Safely Adapted to the Oral Environment

Manufactured using high-purity zirconia powder (≥99.5%) with harmful metal ions (such as lead and mercury) controlled below 0.001%.
Through precise sintering control, the surface roughness is reduced (Ra ≤0.2 μm), minimizing mechanical irritation to oral tissues.
Zirconia's strong chemical inertness ensures it does not corrode or release harmful substances in the moist, acidic, or alkaline environment of the mouth, and does not trigger immune rejection.

Benefits:

① Safe and Non-Irritating: Can be in direct contact with oral mucosa and gingival tissues without causing redness, itching, or allergic reactions. Suitable for patients prone to allergies.
② Wide Clinical Applicability: Complies with standards such as YY 0620 for dental zirconia ceramic materials and is safe for crowns, bridges, inlays, and long-term intraoral restorations.
③ Enhanced Patient Confidence: High biocompatibility reduces clinical risks and minimizes material-related complications, improving patient trust in treatment plans.

3. Various Shades: Precisely Matching Natural Tooth Aesthetics

Trace amounts of inorganic pigments (such as erbium oxide and praseodymium oxide) are added to the zirconia powder and uniformly dispersed using vacuum mixing technology (color distribution deviation ≤2%).
After pre-sintering, a stable base shade is formed.
The material is available in five major shade systems (A, B, C, D, and BL), covering 19 shades in total-including A1–A4, B1–B4, C1–C4, D2–D4, and BL1–BL4-matching the majority of natural tooth colors.

Benefits:

① Highly Aesthetic Results: Shades are selected to closely match natural dentition. Combined with superior transparency, restorations blend seamlessly with surrounding teeth, eliminating the "fake tooth" appearance.
② Accommodates Diverse Needs: Suitable not only for standard shade matching but also for special cases such as tetracycline-stained teeth or fluorosis, expanding clinics' aesthetic treatment capabilities.
③ Consistent Quality: Each zirconia block undergoes strict color-difference inspection (ΔE ≤ 1.0 within the same shade). Ensures stable shade consistency in bulk orders and uniform color across multi-tooth restorations.

4. Easy to Grind & Edge Groove Design: Enhancing Processing Efficiency and Reducing Material Loss

The pre-sintering process precisely controls material density (3.6–3.8 g/cm³), keeping hardness in the optimal milling range (HRC32–38) and reducing cutting resistance.
The 98 mm zirconia disc incorporates an accurately engineered edge-groove design that fits perfectly with mainstream milling machine clamps, enabling fast positioning and preventing displacement during machining.

Benefits:

① Higher Processing Efficiency: Cutting resistance is reduced by 25% compared with standard zirconia, lowering single-crown milling time to under 3 minutes. Combined with fast-sintering furnaces, supports batch production with same-day delivery.
② Lower Material Loss: Improved grindability reduces chipping and micro-fractures during milling. Material utilization reaches over 90%, reducing waste by about 10% compared with conventional zirconia blocks.
③ Stable and Accurate Milling: The edge-groove system ensures positioning accuracy within ≤0.02 mm. Finished restorations achieve a smooth surface (Ra ≤0.3 μm), reducing polishing steps and lowering rejection rates caused by positioning deviation.
