Zirconium Crown: Materials, Advantages and Disadvantages

Zirconium crowns are a type of dental crown that is made from zirconia, a type of ceramic material that is known for its strength, durability, and aesthetic properties. These crowns are used to restore damaged, decayed, or broken teeth and can be an alternative to other types of crowns, such as metal or porcelain-fused-to-metal crowns.

Zirconium crowns are made using computer-aided design and computer-aided manufacturing (CAD/CAM) technology, which allows for precise and accurate shaping of the crown to fit the patient’s tooth. The zirconia material used is biocompatible, which means it is safe to use in the mouth and does not cause any adverse reactions.

Some of the advantages of zirconium crowns include their strength and durability, which makes them resistant to chipping and cracking. They are also highly aesthetic, as the translucent nature of zirconia allows for the crown to closely match the natural color and appearance of the patient’s other teeth.

Overall, zirconium crowns can be a good option for patients who need a dental crown and want a durable, aesthetically pleasing restoration.

Advantages of Zirconium Crowns

There are several advantages of zirconium crowns, which include:

Strength and Durability

Zirconium crowns are known for their high strength and durability, making them a long-lasting solution for restoring damaged or decayed teeth. They are resistant to chipping and cracking, which means they can withstand the normal wear and tear of everyday use.

Aesthetics

Zirconium crowns are highly aesthetic, as they closely match the natural color and appearance of the patient’s other teeth. The translucent nature of zirconia allows light to pass through, giving the crown a natural-looking appearance.

Biocompatibility

Zirconium is a biocompatible material, which means it is safe to use in the mouth and does not cause any allergic reactions or adverse effects.

Minimal Tooth Preparation

Zirconium crowns require less tooth preparation compared to other types of crowns, as they can be made thinner while still maintaining their strength and durability.

Resistance to Corrosion

Zirconia is a non-metallic material, which means it is highly resistant to corrosion and does not react with other materials in the mouth.

How long do zirconia crowns last?

On average up to 15 years, and with proper care up to 20 years.

How do I care for zirconia crowns?

The care for single restorations is simple: just brush twice a day, clean the interdental spaces with floss, rinse your mouth after each meal or snack.

A zirconia crown bridge requires special care: in addition to the above steps, you need to use an irrigator daily to remove food debris from hard-to-reach places.

The general rule is to have professional oral hygiene once every six months!

What is better for a chewing tooth: zirconia or E-max ceramic?

Lateral teeth carry almost all the chewing load, so they need a strong material for crowns. It is definitely better to restore a chewing tooth with a zirconium dioxide crown.

Can complications arise?

If the prosthetics with zirconium is carried out with strict adherence to the rules of technology, and the teeth are properly prepared for the installation of the crown, no complications should be observed after the treatment. But if you suddenly have a tooth under the crown, your gums are swollen, your body temperature rises, you should urgently go to the clinic and see a doctor. Such signs may indicate the onset of the inflammatory process.

It’s important to discuss the potential advantages and disadvantages of zirconium crowns with your dentist to determine if they are the best option for your individual needs. Your dentist can help you weigh the pros and cons of different types of crowns and make a recommendation based on your specific situation.
