Zirconium (Zircon) is a dental restorations material used in endodontic and restorative joints and permanent dental implants. It has various medical uses due to its good properties which characterize it for durability and 100% bio-compatibility with the dental structure.
There are two types:
1- Solid zircon, with low transparency.
2- Highly transparent zircon, with lower hardness.
As for solid zircon it has a higher color intensity compared to high-transparency zircon and it can better resist the causes of dental problems.
It is better suited for treated teeth roots as it provides stronger support for weak teeth.
It is more suitable for the back teeth due to its low transparency.
Unlike high-transparency zircon which fits more the front teeth and gives a beautiful appearance similar to natural teeth.
There are many advantages in using zirconium crowns, the biggest advantage is the distinguished aesthetic appearance and their transparency which gives a very natural look, as the appropriate degree of transparency can be controlled to mimic the transparency of natural teeth giving a more confident smile!
What distinguishes it most is its strength and durability, in addition to its bio-compatibility, which is very important and that is what makes most doctors turn to this type of crowns, because it does not stimulate the body to produce reactions or an immune response such as inflammation.
Zirconium crowns do not have a metallic lining on the gum so, no allergic reactions would be made by the body, which means that they are biologically safe.
It is also one of the strongest types of dental crowns and about five times stronger than porcelain crowns.
Like many other dental procedures, there can be potential defects with the use of zirconium crowns, such as:
Erosion on other teeth: This makes some doctors hesitate when using zircon crowns, fearing that the hardness of zircon will cause erosion on the corresponding teeth.
Opaque appearance: It is one of the possible defects that makes it look unnatural and difficult to match the color with the surrounding teeth, this happens in homogeneous zircon crowns made only of zircon, this can be a big problem if the crowns are in the front teeth, but not when it’s located in the hidden back teeth here it is not considered a big problem and can be bypassed.
