Zirconium
Zirconium teeth are a type of dental crown made from a material called zirconium oxide. They are considered a more durable option than porcelain crowns and offer aesthetic advantages.
What Are the Features of Zirconium Teeth?
The features of zirconium teeth are as follows:
- Durability: Zirconium teeth are highly durable. When applied to the tooth, they provide great strength and resistance, making them ideal for use on back teeth.
- Aesthetics: Zirconium crowns offer an appearance very close to the natural tooth color and, thanks to their light-transmitting properties, provide a natural aesthetic. Therefore, they are also preferred by patients with aesthetic concerns.
- Metal-Free: Zirconium teeth do not contain metal, making them suitable for patients with metal allergies. In addition, they do not cause discoloration of the gums.
- Fit and Comfort: Zirconium crowns are produced to match the natural structure of the teeth, providing better fit and comfort.
- Low Allergy Risk: Zirconium is a biocompatible material, minimizing the risk of allergic reactions in the gums or mouth.
What Are the Uses of Zirconium?
The areas where zirconium is used can be listed as follows:
- Front Teeth: Due to its aesthetic appearance, it is commonly used on front teeth. It provides color and translucency compatible with natural teeth.
- Back Teeth: Thanks to its durability, it is also used on back teeth. Since it is resistant to chewing forces, it is suitable for teeth in this area.
- On Dental Implants: Zirconium crowns can be placed over implants to provide a natural appearance.
- After Root Canal Treatment: Zirconium crowns can be applied on teeth that have undergone root canal treatment to strengthen and protect them.
- Tooth Shape Irregularities: Zirconium crowns can be used to correct irregularities in the shape or size of teeth.
How Is Zirconium Crown Applied?
- Preparation: An intraoral X-ray is taken, and the condition of the tooth is evaluated. A thin layer of the tooth surface is shaved down to help the crown fit better.
- Digital or Physical Impression: Precise measurements of the teeth are taken to ensure a perfect fit for the crown. Digital scanning devices or traditional silicone impressions may be used.
- Temporary Crown: Your dentist may place a temporary crown until the zirconium crown is ready. This helps protect your teeth and maintain an aesthetic appearance.
- Laboratory Process: Based on the impressions taken, the zirconium crown is produced in a laboratory. This process usually takes a few days.
- Fitting: The produced zirconium crown is placed on the tooth and adjusted for proper fitting. Minor adjustments can be made if necessary.
- Permanent Bonding: Once the crown fits correctly, your dentist permanently bonds it using a special dental adhesive.
- Final Check: After placement, your dentist will check the fit and comfort of the crown.
Can Zirconium Crowns Be Applied at Any Age?
Zirconium crowns can generally be applied to patients of all age groups, but in some cases, special consideration and evaluation may be required. Here are some factors to consider regarding the applicability of zirconium crowns in different age groups:
- Tooth Development: In children and adolescents whose teeth have not fully developed or are still changing, zirconium crowns are generally not recommended. Crowns applied before full tooth development may become incompatible as the teeth grow and change.
- Dental Conditions: The overall health of the teeth, the presence of cavities, fractures, or root canal treatments can affect zirconium crown application. Your dentist will evaluate your teeth and determine the most suitable treatment option. In older adults, the condition of the teeth, gum health, and chewing function can affect whether zirconium crowns are appropriate. When the root structure and gums are in good condition, zirconium crowns can be successfully applied.
- Jaw Health: Jawbone health is also an important factor in older adults. Bone loss or other health issues in the jaw may affect the success of the crown application.
Can the Tooth Under a Zirconium Crown Decay?
Since zirconium crowns are produced with great precision, they fit perfectly on the prepared tooth surface. This prevents bacteria from entering the area between the tooth and the crown, thereby eliminating the risk of decay underneath.
How Long Can I Use a Zirconium Crown?
The duration of use depends on the individual and usage conditions, but zirconium crowns generally last longer than metal-based prosthetics. As long as you maintain good oral hygiene, follow your dentist’s advice, and attend regular check-ups, you can use them for many years.
