ZIRKONYUM BRIDGES AND CROWS
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.
Plus 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 A ZIRCONIA CROWN?
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
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.
ADVANTAGES OF A ZIRCONIA CROWN
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.
DISADVANTAGES OF A ZIRCONIA CROWN
The tough, durable nature of a zirconia crown can work against it as well as in its favour. This material has an abrasive quality which can cause friction against the root of the tooth as well as other teeth.
HOW IS A ZIRCONIA CROWN FITTED?
The process is similar to that for other crowns. It involves two stages: preparation (first stage) and the fitting of the crown (second stage).
A zirconia crown must be cared for in the same way as your natural teeth.
