Zirconia dental veneer is one of the most resistant and beautiful types of dental veneers made of metal-free zirconium dioxide. This coating is used for denervated, broken, discolored teeth or implants and is popular due to its high strength, long durability and natural appearance.

Zirconia is resistant to pressure, wear and stains, does not cause sensitivity or gingivitis and can be designed and installed in one session with CAD/CAM technology. Of course, its price is higher and its replacement is more difficult than other covers. With oral hygiene and regular visits, the lifetime of zirconia veneer is usually 10 to 15 years or more and its price starts from 8 million tomans.

What is zirconia veneer?

Zirconia crown is a type of dental crown which is made of a very resistant material called zirconia; The material scientifically called "Zirconium Dioxide" has become very popular in recent years due to its resemblance to natural teeth, extremely high resistance and no need for metal.

These veneers are usually used for teeth that have been severely damaged, have undergone root canal treatment, or need to be strengthened and beautified. In addition to resisting chewing pressures, zirconia also harmonizes well with the color of natural teeth in terms of aesthetics and is a suitable option for those who are looking for a combination of durability and natural appearance.

Unlike metal or ceramic-metal (PFM) crowns, zirconia crowns are made entirely of ceramic, and for that reason, they are an ideal option for people who are allergic to metal or care about the appearance of their teeth.

A 2021 study by the American Dental Association (ADA) revealed that 99% of dentists use this crystalline mineral for natural tooth restorations.

Benefits of zirconia dental veneers

1. Strength

One of the biggest advantages of zirconia is its high strength and durability. Imagine the amount of pressure your back teeth exert when chewing food. Dental crowns must be made of a very durable material, so zirconia can be a great option for back teeth. Also, due to the high strength of this material, the dentist will not need to grind or prepare much of the tooth.

2. Longevity

According to a 2017 randomized controlled trial published in the Journal of Dentistry, zirconia-based crowns performed similarly to metal crowns over 5 years. One-piece zirconia crowns, known as Monolithic Zirconia Crowns, are particularly durable.

Also, a more recent study in 2022 showed similar results about the durability of these coatings on implants. www.healthline.com

3. Biocompatibility

Many dentists choose zirconia because it is biocompatible (Biocompatible), meaning it is less likely to cause an immune response such as inflammation. A review of studies conducted in 2020 also confirmed this and showed that zirconia veneers perform very well clinically.

4. Do the coating on the same day

Many dentists can make zirconia veneers in their office and install them the same day; Without the need to send a tooth mold to the laboratory.

In this process, CEREC technology is used, or "Ceramic Restoration in the Office", which is based on Computer Aided Design and Manufacturing (CAD/CAM). With a special device, the dentist carves the crown from a block of zirconia. This method eliminates the need for a second visit to deliver the coating. However, not all practices are equipped with this technology or offer zirconia veneers.

Disadvantages and limitations of zirconia veneer

Although zirconia veneers are durable and have a gentle behavior towards other teeth, they also have some disadvantages.

Zirconia itself does not match the color of natural teeth easily and needs to be coated with other compounds to have a more natural appearance.
One of the possible disadvantages of zirconia veneers is their matte appearance, which may make the appearance of the veneer not look very natural. This is especially the case with monolithic zirconia crowns, which are made only of zirconia and do not have a combination of ceramic or metal. Of course, this issue is usually less important for the back teeth.
Some dentists are hesitant to use zirconia veneers in some cases, because the high hardness of this material may damage the opposite teeth (the lower teeth facing the veneer) and cause their enamel to wear away.

However, according to a 2021 study, it was found that Feldspathic Porcelain wears much more than zirconia ceramic.

Zirconia veneer installation steps

There are two main methods for installing dental veneers:

In the first method, the dentist prepares your tooth in one session and installs a temporary crown, then in the second session he attaches the permanent crown to the tooth.

In the second method, if the dentist has the necessary equipment and technology to make a zirconia veneer in the office, all steps are done in one day.

1. Two-session method

In this method, the dentist performs the following steps:

Before preparing the tooth, he takes a mold of the tooth to make a temporary crown.
If needed, it cuts a part of the outer layer of the tooth.
After sharpening, makes a final mold from the tooth to make a permanent cover.
temporary cover on the tooth to protect the tooth.
Sends the molds to a dental lab to make a permanent crown.
After the crown is ready, he invites you for a second session to attach the final crown to the tooth.

2. Installation of the coating on the same day

In this method, the dentist performs the following steps:

examines your mouth, takes digital images of the tooth and prepares the tooth for work; This step may also include the injection of local anesthesia.
Using a digital scan taken from the images, he designs and produces the cover in the same office.
Finally, he installs and fixes the prepared veneer on your tooth.

How long does zirconia veneer last?

Zirconia crowns typically last between 10 to 15 years or even longer, provided they are cared for properly. Factors such as maintaining oral and dental hygiene, not grinding teeth, visiting the dentist regularly and not using teeth to break hard objects can increase the life of this type of coating.

Zirconia cover cost

The cost of each unit of zirconia coating varies on average between 6 and 8 million Tomans. This price range depends on various factors, including:

Type and quality of materials used
Dentist's skill and experience
Equipment used (such as CAD/CAM technology for digital veneer manufacturing)
The geographical location of the clinic and its tariffs
Specific conditions of each patient, such as the need for additional treatments before veneer installation

Click to know prices of dental veneers

In general, zirconia veneers have a higher price than other types of veneers, but in return they are more durable, have a more natural appearance, and are more compatible with the body. Also, in some cases, it is possible to perform the treatment in one day, which can be effective in the final cost.

Summary: Why is zirconia veneer a smart choice?

Zirconia veneers have become one of the most popular options in modern dentistry due to their high durability, natural appearance, compatibility with the body, and the possibility of same day fabrication. Although they may cost more than other types of veneers and in some cases it is difficult to match their color with natural teeth, their many advantages compensate these limitations to a large extent.
