Zirconia dental crowns combine the strength of metal and the aesthetics of porcelain.
Zirconia is about five times stronger than porcelain and is the preferred choice for restoring the back teeth and for patients with teeth grinding.
The preparation process for a zirconia crown requires two sessions. During the first session, the dentist will initially take X-rays to rule out any infection of the person’s teeth and jaw areas.
The dentist will then apply local anesthesia and proceed to reshaping the tooth that accepts the crown. The dentist creates a cast of the teeth that will receive the crown and sends the cast to a lab specializing in zirconia crowns. While waiting for the zirconia crown, the patient will be provided with an interim temporary crown to cover the site.
At the lab, the ceramist will upload the scan into a computer with CAD software that designs the zirconia crown. Once the permanent zirconia crown has been fabricated, your dentist will replace the temporary crown with the permanent one in the following appointment.
Dental bridges are indicated when you have one or more missing teeth. A typical 3-unit bridge consists of three crowns joined together, which is used to replace a single missing tooth.
Bridges generally require shaping of the teeth surrounding the missing tooth. Traditional bridges are made of metal, porcelain fused to metal or zirconia.
Zirconia crowns and bridges can last between 10 and 15 years, on average. The lifespan can vary depending on several factors, including:

Aesthetics: Zirconia crowns are known for their natural and lifelike appearance. They can be customized to match the color, shape, and size of your adjacent teeth, ensuring a seamless and natural look.
Biocompatibility: Zirconia is a biocompatible material, which means it is well-tolerated by the body and unlikely to cause allergic reactions or adverse tissue responses.
Durability: Zirconia is highly durable and resistant to chipping or cracking. This makes zirconia crowns a reliable option for withstanding the forces of biting and chewing.
