137 Zirconia – What are Zirconia Crowns? (1 of 5)
Dental crowns are a common solution for restoring teeth that begin showing signs of wear such as cracks and chips. Crowns help strengthen weak teeth while maintaining the appearance of the natural tooth. Various materials can be used to create a crown, including zirconia. Numerous factors should be considered when selecting what material should be used such as the location of the tooth, budget, durability, and appearance. This article will review the benefits and challenges associated with zirconia crowns.
Dentists started using porcelain for creating crowns because material closely matches the color of the natural teeth. Unfortunately, porcelain is less durable than gold and other types of metal. Zirconia does have the potential to chip, crack, and break, however, can closely match the natural teeth. It is commonly used to create crowns because it is incredibly strong and durable.
Advantages
Zirconia is a white solid ceramic glaze and is a newer material with the unique properties of metal-like strength combined with a natural tooth-like appearance. Zirconia crowns are continuously evolving and improving in their performance and appearance.
Below are some of the key benefits associated with zirconium crowns:
1. Color which closely matches the natural teeth
2. Durable
3. Easily shaped which allows the dentist to fit and place the crown in a single appointment
4. Appearance can be enhanced by layering zirconia with porcelain
5. Crown is bonded or cemented to the tooth, giving the dentist flexibility in treatment offerings
6. Zirconia is biocompatible and will not cause adverse reactions
There are unfortunately some disadvantages which should be considered when patients are evaluating zirconia crowns. While the material closely mimics the appearance of the natural teeth and is a better solution than gold or other metals, it is also more opaque. Patients who require a crown on one of the teeth in the front of the mouth may benefit from a material other than zirconia. It can be challenging to achieve a close match to the natural teeth with zirconia alone. This is exaggerated when the tooth is highly visible in the front of the mouth. A key benefit of zirconia is that is it incredibly strong. In some cases, it can be too strong. When the crown requires adjustments to achieve an even bite or needs to be filed down, it can be difficult to work with.
Oral Hygiene
Regardless of the material selected for use in a crown, patients must practice good oral hygiene. This includes brushing the teeth at least twice each day and daily flossing. Patients should focus on consuming a well-balanced diet and avoid consuming large amounts of sugary food and drinks. Regular visits to the dentist are imperative and patients will receive a professional cleaning and examination during these appointments. The dentist will also evaluate the crown during these visits to ensure there are not any issues. Issues which are quickly identified are easier to repair.
Follow up with the dentist to determine if you may be a good candidate for a zirconia crown. This treatment option can be an excellent solution for restoring damaged teeth. The dentist can help determine the best material to use for the crown based on the location of the damaged tooth, cost, treatment goals, and the patient’s specific needs.
