What Are Zirconia Crowns? Who Are They For?

Zirconia is a durable, tooth-colored ceramic material used in dentistry to make crowns and bridges. Because it contains no metal framework, the way it lets light through is closer to a natural tooth, and it is often considered for patients with aesthetic expectations.

When Are Zirconia Crowns Considered?

• Teeth with major structural loss that cannot be restored with a filling
• Teeth that have had root canal treatment and have become weak
• Teeth with color, shape or size problems
• Replacing missing teeth with a bridge
• Restorations placed on dental implants

Properties of Zirconia

• Aesthetics: It matches the color of natural teeth and does not create a metallic appearance.
• Biocompatibility: It is a tissue-friendly material and does not cause metal-related discoloration of the gums.
• Durability: It is resistant to chewing forces.

As with any material, whether zirconia is suitable for each case is assessed by the dentist based on factors such as the condition of the tooth, your bite and any teeth-clenching habit.

Treatment Steps

1. Examination and planning: The condition of the teeth and gums is assessed, and X-rays are taken if needed.
2. Tooth preparation: Under local anesthesia, the teeth are shaped to receive the crowns.
3. Impressions: Impressions are taken using conventional or digital methods, and temporary crowns are placed.
4. Try-in and shade selection: Fit and color are checked.
5. Cementation: The crowns are permanently cemented in place.

Care Recommendations

Because there is a natural tooth under a zirconia crown, oral care is very important. Brushing twice a day, using dental floss or an interdental brush, and regular checkups are recommended. If you clench your teeth, your dentist may recommend a night guard. For more information about cosmetic dental treatments, you can visit our smile design page.

Frequently Asked Questions

How long do zirconia crowns last?

Their lifespan varies depending on oral hygiene, eating habits, teeth clenching and regular checkups. With good care and checkups, they can be used for many years.

What is the difference between zirconia and porcelain?

In conventional porcelain-fused-to-metal crowns, the framework is metal. With zirconia, the framework is also tooth-colored, so the way it transmits light gives a more natural look.

Are the teeth reduced for zirconia crowns?

A certain amount of tissue is removed from the tooth surface so the crown can fit. The amount is determined by the dentist depending on the case.
