What Is a Zirconia Crown and Are They Stronger than Other Materials?
Dental crowns are essentially a way to fix broken, cracked, weak, or misshapen teeth. They can be made of precious metals, ceramic, resin, porcelain, or porcelain fused to metal. With all of the various materials that dental crowns are made of, it’s helpful to learn about them and why your dentist might choose one over another.
While there are many material options for dental crowns, zirconium oxide are gaining popularity. Reasons why zirconia is a great option is because zirconia is stronger than porcelain and some metal alloys. Additionally, zirconia crowns cause less damage to opposing teeth.
There are two types of zirconia: framework zirconia and full contour zirconia. Framework zirconia is best for anterior and posterior multi-unit bridges and is more natural-looking. Full contour zirconia is usually made from one material and is not as natural-looking in appearance.
The advantage of zirconia crowns is that they are the most durable monolithic ceramic because it is made without any added materials. They are stronger, chip-resistant, and can withhold stronger loads of pressure.
In Dr. Shaun’s opinion, the biggest disadvantage of zirconia crowns is that they frequently don’t match well in terms of shade to existing teeth. Zirconia often has issues with translucency. For these reasons, in his practice, Dr. Shaun typically only places zirconia crowns on second molars.
In conclusion, zirconia crowns are a great option primarily for their durability. If your dentist has recommended crown treatment, ask if zirconia is an option for you!
