What is Dental Zirconia?

Dental zirconia, short for dental zirconium dioxide (ZrO₂), is a type of ceramic material widely used in modern dentistry for making crowns, bridges, implants, and other restorations. It is known for its outstanding strength, biocompatibility, and natural aesthetics.

Why Dental Zirconia Matters

As dental technology has advanced, zirconia has become a go-to material for both anterior and posterior restorations. Compared to traditional metal or porcelain-fused-to-metal restorations, zirconia offers several key advantages:

High Strength: With flexural strength typically ranging from 700 MPa to over 1200 MPa, zirconia is suitable for single crowns, long-span bridges, and implant abutments.

Biocompatibility: Zirconia is well tolerated by the body, with minimal allergic or inflammatory responses.

Excellent Aesthetics: Modern multi-layer and pre-shaded zirconia blocks offer natural color gradients and translucency for lifelike restorations.

Durability: Zirconia restorations are highly resistant to wear, fracture, and chemical corrosion.

Types of Dental Zirconia

At HONCHON, we offer a full range of zirconia block options to meet different clinical needs:

White Zirconia Blocks: Suitable for custom coloring and layering, ideal for technicians who prefer more control over the aesthetic outcome.

Pre-Shaded Zirconia Blocks: VITA 16 colors available, for efficient and consistent results without manual staining.

Multilayer Zirconia Blocks: Seamless color gradient from cervical to incisal, mimicking the look of natural teeth.

Applications in Restorative Dentistry

Dental zirconia is used to produce:

Full-contour crowns and bridges

Copings and frameworks for layered restorations

Implant abutments

Inlays, onlays, and veneers (in selected indications)

Thanks to its excellent strength and natural appearance, zirconia is especially preferred for posterior crowns and long-span bridges, but newer ultra-translucent types also perform well in anterior restorations.
