Advantages of Choosing Zirconia Crowns

Zirconia crowns are highly biocompatible, as the smooth surface helps to reduce plaque accumulation. Layered zirconia crowns are extremely durable. Even though the porcelain used for layering does not have the strength of solid zirconia, they are designed to bond with the zirconium substructure, making chipping or fracturing extremely rare. The material also promotes a healthy tissue response.

Due to a wide variety of factors including chemical composition and processing requirements, there are many ways zirconia can be manufactured to suit the needs of the patient. This customization minimizes the margin for error and ensures excellent fit for each individual.

Zirconia is suitable for patients with metal allergies or who would prefer to have metal-free restorations.

Zirconia is metal-free, which prevents darkening around the gingival area. This eliminates the possibility of metal margins becoming exposed due to gum recession.

The translucent nature of this material can transmit the color of adjacent teeth and it is manufactured in a wide variety of shades, making it easy to accurately match the color of the patient’s natural teeth.

Using computer-aided design and manufacturing processes provide patients with a precise fit, reducing the chair-side time required for adjusting and cementing these restorations.

Zirconia crowns can be conventionally cemented in place by using Bisco’s Z-Prime Plus, then applying the bonding agent of choice to prep, followed by dual-cure resin cement.

Zirconia crowns are comfortable for patients, as they do not transmit hot and cold in the same way as conventional PFMs.

Are There Any Disadvantages of Having a Zirconia Crown?

The disadvantages of zirconia crowns are minimal. The toughness of the material has raised some concerns about friction against the tooth root and wearing down opposing teeth. Frequent check-ups, however, help to reduce the possibility of damaging opposing teeth. Initially, only bone-white substructures could be produced for zirconia crowns, which could sometimes create problems in achieving an aesthetically-perfect appearance. Now, however, the newer generation of materials are pre-shaded and can be fabricated to provide highly aesthetic and naturally-perfect restorations with minimal tooth reduction, meeting or even exceeding patient demands for high-quality work! Currently, the demand for zirconia far exceeds the demand for PFMs, and these older-style restorations are becoming a thing of the past.
