Modern science and technology have revolutionized the process of fabricating crowns for dental restoration. One of the crown options that is gaining popularity is zirconia, due to its excellent properties and aesthetic qualities.
Advantages of Zirconia Crowns
- Durability – Zirconia crowns are typically stronger than traditional porcelain crowns, making them well-suited for molars and other highly visible teeth that are subject to heavy chewing.
- Biocompatible – Zirconia crowns are composed of zirconium dioxide, which is biocompatible with the surrounding teeth and gums. This makes them ideal for less invasive and more comfortable procedures.
- Odour-resistant – Zirconia crowns are resistant to odours which makes them a popular choice for patients with dense staining and smoking habits.
It is important to consider the shape, size, and position of zirconia crowns when designing them for optimal cosmetic appeal. The crown should be contoured to the surrounding teeth, with careful consideration given to symmetry and the ultimate result after placement.
Colour selection for zirconia crowns is critical for a natural, aesthetic result. The crowns must be compatible in colour with the surrounding teeth and materials to give the most natural look possible.
Finally, esthetics also depend on the way the light is reflected from the crowns surfaces. Zirconia crowns should be highly polished in order to achieve a beautiful, esthetic result.
To summarise, zirconia crowns are a great option for restoring teeth, due to their superior strength and biocompatibility. When properly designed and fabricated, zirconia crowns can be made to look just as beautiful as a natural tooth, giving excellent cosmetic results.
