This type of crown is made from zirconia, 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. Plus there is no fear about the body rejecting zirconia or displaying an allergic reaction to it. It is safe to use and preferred by many people to porcelain fused to metal crowns.
There are three advantages which are:
- Strength: zirconia crowns last longer than other types of crowns.
- Aesthetics: these crowns have an attractive translucent colour which blends in well with the other teeth.
- Retain more of the existing tooth: minimal preparation is required which means more of the original tooth is preserved. This is useful if the crown needs to be removed.
So, a good choice if you are looking for a strong, long lasting and visually appealing crown. They are ideal at covering signs of damage or staining as well as helping to maintain the function of the tooth.
