A Zirconia crown is a popular type of all-ceramic crown which is worn to improve the appearance of a tooth which has become stained or disfigured over the years. They are durable, easy to wear and long lasting. In addition, Zirconia crowns have a translucent appearance which means that they are indistinguishable from your own teeth. It is hard to spot a Zirconia crown amongst natural teeth.
What is zirconium?
Zirconium is one of the oldest and most abundant elements in the terrestrial crust and it is the basis for Zirconium oxid. It is a very strong material which is compatible with the human body. Zirconia is used in many other medical applications such as artificial joints and is known for its strength and durability. Zirconia is a type of crystal which is long lasting and indestructible.Zirconia crown is safe to use and preferred by many people to porcelain fused to metal crowns.
The advantages of zirconia
Zirconia crowns are extraordinary strong and can withstand most chewing and biting activities. They are very resistible to high temperatures and, as a rule, don’t cause teeth hypersensitivity. Due to the fact that they are made of crystal, zirconium crowns are much stronger than porcelain and porcelain-fused-to-metal ones. Furthermore this very acid-proof material prevents the absorption of pollutants and makes cleaning easier and can last longer than other type of crowns.
It is hard to differentiate a Zirconia crown amongst natural teeth. In addition, Zirconia crowns can be modified, according to the shape and size of teeth it will be placed alongside with. These crowns have an attractive translucent colour which blends in well with the other teeth. These crowns are translucent and smooth, matching the size, color and shade of your original teeth therefore are a perfect choice for attractive front teeth restorations.
Due to their biocompatible structure, Zirconia crowns rarely provoke allergic reaction or gum irritation.
Minimal preparation is required which means more of the original tooth is preserved. This is also useful if the crown needs to be removed.
Unlike porcelain-fused-to-metal crowns (PFM), all-porcelain crowns don’t have a problem of a dark line as they all made of white porcelain that perfectly imitates your natural tooth enamel. There are no black margin in case of age-related retreat of the gums, as this might be the case with metal restorations.
