Zirconia Crowns

Zirconia crowns and bridges are fast becoming the most popular choice amongst dentists today.  Zirconia is made from a form of crystal, it is an imperishable and extremely long lasting material which is why it’s perfect for creating crowns and bridges.

At our laboratory the zirconia structure is designed with 3d scans of the patient, impression, or model. The core is then milled from a block of zirconia in a soft pre-sintered state. Once milled, the zirconia is sintered where it reaches its full strength of 1200MPa. They are typically five times stronger than porcelain fused to metal crowns.

Aesthetically zirconia crowns are pleasing to the eye as not only do they look like a real tooth, they also have the ability to reflect light in the same way.  This is especially important to those patients who might require a crown positioned near the front of their mouth. They are more streamlined and less bulky than some porcelain veneers making them a common choice.


One of the major health benefits of zirconia crowns is that is biologically safe to use in your mouth for many years and will not be rejected.  The patient will also avoid having a black gum line which can be visible when using a porcelain fused metal crown.

The use of Zirconia crowns allows the dentist to retain more of the original tooth, which means there is less preparation time needed to perform the procedure.  This is not only beneficial to the dentist in man hours but also to the patient in case the crown has to be removed at a later date.

Although they are a popular choice these days, some dentists still prefer other options like PFM crowns or indeed good old fashioned gold.  This is because due to its durable nature, it may cause friction against the root of the tooth it is fixed upon or the neighbouring teeth.  There is also a small chance that decay might not be noticeable until the crown falls off.
