What is a zirconia crown?

Zirconia is a white, highly durable ceramic. A crown is like a cap that fits precisely over a reduced tooth and covers it on all sides. The grey line at the gum margin seen with metal-based porcelain does not occur with zirconia. Because it transmits light much like a natural tooth, it can be used comfortably at the front of the mouth too.

When is it chosen?

• Protecting root-treated teeth or teeth with large fillings
• Fractured or heavily worn teeth
• Bridges (replacing a missing tooth by anchoring to its neighbours)
• Implant crowns
• Patients with metal allergies

The process

Preparation and impression

Under local anaesthesia the tooth is reduced just enough to make room for the crown. A digital scan is taken and a temporary crown is fitted.

Try-in

The framework made in the laboratory is tried in the mouth; shade and margin fit are checked.

Cementation

The finished crown is bonded to the tooth with permanent cement and the bite is adjusted.

Care

Brush as you would a natural tooth and keep the gum margin clean with interdental brushes and floss. A protective night guard is advised for people who grind. A check-up every six months is enough to monitor the margins and the gum.

How does it compare with all-ceramic (lithium disilicate)?

All-ceramic crowns are slightly better at transmitting light and are preferred for single front teeth. Zirconia stands out for strength on back teeth and in bridges. Your dentist will advise which suits each area.
