Zirconium crowns, also called Zirconia(Cercon), have quickly become the preferred material for dental crowns. Zirconium is a very strong substance that can endure wear and tear of everyday use. When looking at Zirconium crowns from an aesthetic point it is clear and very similar to a natural tooth and reflects light the same way. This may be important if your new crowns are on the front of your mouth and it is particularly relevant in cases where the crown will be seen next to the natural teeth.

Why choose Zirconia crowns?


Zirconium is non- allergenic, bio-compatible with no electrical conductivity.


Zirconia metal gives strength, giving peace of mind against chips or breakages, while the porcelain outside gives the appearance of a normal tooth. Full porcelain crowns have occasionally been known to do this. This is rectified by producing the crown from the Zirconia metal, and merging it with the porcelain on the outside.


Zirconium crowns allow light to pass as a normal tooth would which gives a very natural look, unlike other metal cores that block light. Often called 'Non Allergic' crowns as the body has no allergic reactions to them and they are bio-compatible as they are produced from a natural material, unlike some metal Amalgam fillings.


Zirconium crowns will not wear away or erode because of the strong ceramic material used. The normal black gum line that you sometimes might see around a porcelain fused metal crown will also be absent, giving a greater aesthetic look. There is no electrical conductivity so too hot or cold sensations to not arise.

Advantages of Zirconium Crowns

-    Zirconium crowns or bridges do not erode

-    No black gum line as seen with porcelain fused metal crowns

-    Sensitivity to hot/cold is non existent because there is no electrical conductivity

-    Stronger, more durable and more natural looking teeth

-    Encourages gum tissue regeneration



1.     Consultation and X-Ray

2.     To accommodate the new zirconium crown a section of your natural tooth’s structure is removed.

3.     Impression taken of the original tooth to produce a permanent crown

4.     Temporary crown fitted whilst the permanent crown is being made

5.     Fixing of the permanent zirconium crown
