What are the advantages of zirconia crowns?

Zirconia crowns have a translucent appearance, which means that they are indistinguishable from your own teeth. They create a more natural appearance since they harmonize with gums. Zirconia crowns combine aesthetics and stability, which makes them favorable.

What are the advantages of zirconia crowns compared to metal ceramic crowns?

• Zirconia crowns have a natural appearance since it’s translucent; and this is important in front teeth where aesthetics is key. Metal ceramic crowns do not give a desirable result in this sense.
• In zirconia crowns we use mechanical and chemical adhesives called dual cement. This method increases retention and prevents teeth from breaking. 
• Nickel, which causes allergic reactions in some patients, is used in metal ceramic porcelains. In zirconia, the materials used are compatible with the intraoral tissues.
• In metal ceramic porcelains, a dark colored line appears on the tooth-gum border. Such a line does not form in zirconia crowns.
• Metal ceramic crowns can create a bad image in case of gum recession. This does not happen with zirconia crowns.
