Zirconia crowns are the strongest and most aesthetic ceramic crown system in dentistry. As they contain no metal substructure, their biocompatibility is extremely high and they can be safely used by patients with metal allergies.
What is Zirconia?
Zirconium dioxide (ZrO₂) is an extremely hard and durable ceramic material also used in aerospace and aviation industries. In dentistry, it is manufactured as metal-free full ceramic crowns that perfectly mimic the appearance of natural teeth.
Who is it Suitable For?
- Those with metal or porcelain-fused-to-metal crowns who wish to replace them
- Individuals with metal allergies or sensitivities
- Those seeking crowns that can withstand high chewing forces on back teeth
- Those wanting ultra-aesthetic results on front teeth
- Implant-supported crown applications
Zirconia vs Porcelain-Fused-to-Metal
| Property | Zirconia | Porcelain-Metal |
|---|---|---|
| Metal content | None (full ceramic) | Yes (metal substructure) |
| Aesthetics | Very high | Moderate–Good |
| Fracture resistance | 900–1200 MPa | 300–400 MPa |
| Gum compatibility | Excellent | Grey line may appear |
Precision Manufacturing with CAD/CAM Technology
At our clinic, zirconia crowns are designed using digital impressions (intraoral scanner) and produced in a CAD/CAM milling system, eliminating traditional impression errors for perfect fit.
Lifespan
With proper oral hygiene, zirconia crowns can last 15–20 years or more. Our clinic provides a 10-year written guarantee for zirconia crowns.
