- Product Introduction
Products Description
Dental Zirconia Disc is a key material for all-ceramic dental restorations and is widely used in CAD/CAM dental milling systems. It is suitable for crowns, bridges, veneers, inlays, onlays, and implant-supported restorations.
Product Features
1. High Strength & Mechanical Performance
After sintering, zirconia achieves a flexural strength of 800–1200 MPa and a Vickers hardness of around 1200 HV, providing excellent resistance to mastication forces and long-term wear.
It is especially suitable for posterior restorations under high occlusal load.
2. Excellent Biocompatibility
Made from medical-grade zirconia powder with extremely low metal ion content.
It is non-toxic, non-irritating, and does not cause allergic reactions or gingival discoloration.
Safe for long-term intraoral use.
3. Natural Aesthetic Appearance
Translucency ranges from approximately 40%–49% (depending on model type), closely simulating natural enamel optical properties.
Available in multilayer gradient structures (dentin to enamel transition), providing smooth and natural color layering.
Ideal for high-aesthetic anterior restorations.
4. Stable Chemical Properties
Very low water absorption (<0.05%), ensuring long-term color stability.
Resistant to acids, alkalis, saliva, and cleaning agents, maintaining structural integrity in the oral environment.
5. Wide Clinical Application
Suitable for multiple restoration types:
Single crowns
3–6 unit bridges
Veneers
Inlays / Onlays
Implant abutments and restorations
Fully compatible with mainstream CAD/CAM systems, suitable for both dental laboratories and chairside digital workflows.

Manufacturing process
The manufacturing process of zirconia ceramic blocks mainly includes the following steps:
Raw material preparation: Select high-purity zirconia powder, and add appropriate amounts of stabilizers (such as yttrium oxide) and other oxides as needed to improve the performance of the material.
Powder processing: The powder is prepared into particles with good fluidity by spray drying and other methods to facilitate the subsequent molding process.
Molding: The dry molding process is used to press the zirconium oxide particles in the mold by isostatic pressing or dry pressing to form a green body.
Pre-sintering: The green body is pre-sintered at 900-1100℃ to give it a certain strength for subsequent processing.
Machining: The pre-sintered zirconium oxide blank is precisely cut using CAD/CAM technology to form the required shape of dental restorations.
Dyeing: The zirconium oxide restoration is dyed according to the color requirements of the patient's teeth to achieve the ideal aesthetic effect.
Sintering: The dyed restoration is finally sintered at high temperature (about 1450-1600℃) to achieve the required density and mechanical properties.
Surface treatment: The sintered restoration is polished, glazed and other surface treatments are performed to improve its aesthetics and comfort.
