Definition of zirconia veneer
Zirconia is a metal oxide from zirconium (A metal from the titanium family) It is obtained and found all over the world. Many household items such as dinnerware, pipes, and electrical appliances are made of zirconia. It is also an ideal material for dental veneers due to its natural strength and durability. Zirconium crowns for patients seeking posterior veneers (For back teeth) are the best because they need a lot of strength to chew and grind food. The main reasons for the popularity of zirconium veneers are the extraordinary strength and natural appearance it gives to the teeth.
Advantages of using zirconia veneer (Zirconium)
Crowns made of zirconia are becoming more and more popular due to their many advantages.

Different types of zirconium plating
Zirconium crowns can be used for various purposes in cosmetic and restorative dental procedures. They are a great way to strengthen a broken, cracked tooth or cover a stained, discolored tooth or restore the appearance of a dental implant.. Below we introduce two examples of them.
Integrated zirconia crowns (Monolithic):
This type of dental ceramic has zirconium oxide, which makes it almost unbreakable. This solid ceramic is resistant to chipping, cracking and staining. Its color can be chosen to match the surrounding teeth, but it is slightly opaque. Because the matte color is unattractive to many, integrated restorations are usually used for back teeth..

Differences between zirconium veneer and normal veneer (PFM)
PFM coatings (A combination of ceramic and metal) They have been in the market for years and are therefore very reliable. PFMs can last up to 30 years if they are used in the correct positions and in compliance with patient hygiene.. Some of the most important features of conventional coatings are::
- They are robust and suitable for use in all areas of the mouth and in most clinical situations. However, there is a possibility of cracking the ceramic top.
- The clinical success of PFM restorations has been proven through long-term research.
- Clinical research has shown that individual PFM veneers (Single) They will last for many years, and three-unit PFM bridges also have a relatively long lifespan.
- PFM bridges and crowns provide acceptable esthetics, especially in the first few years.
- If the gums recede, the metal edges of the veneer are marked and look like a dashed line.
- It can lead to allergic reactions in some people.
However, the zirconia veneer, as an all-ceramic veneer, has the same structure as PFM, but instead of using metal, white zirconium is used in the center of the veneer..
