Why Choose Zirconium Crowns?
Zirconium or zirconia is biocompatible, hypoallergenic , non conductive material with unique specification of letting light pass through so that the crown looks like a natural tooth. Zirconium, zirconia also provides the extra comfort of not breaking or chipping over a long period of time.
Porcelain has been the traditional material used for dental crowns. Full porcelain crowns however may chip or break. This is overcome by making the crowns from metal, in this case the metal being zirconia, then fusing porcelain to the outside.
The zirconium metal provides the strength while the porcelain provides the outer appearance like a natural tooth. Zirconium crowns allow light to pass through giving it a natural look, unlike other metal bases which block the light. Unlike amalgam fillings and metal alloys , the human body accepts zirconium as a natural material, so you do not need to worry about allergies or adverse reactions unless you are specifically allergic to zirconium.
Another great advantage of using a zirconium crown is that it doesn’t require as much of the natural tooth structure to be removed as with other traditional types of crowns.
Zirconium, zirconia crowns do not corrode over time. They also don’t cause black gum line that you might see with a porcelain fused metal crown if your gums recede. In addition, the hot and cold sensations you might feel with other crowns do not occur because of the lack of electrical conductivity.
Advantages of Zirconium Crowns:
Zirconia
- crowns and bridgeworks do not corrode.
- The typical black gum line seen around porcelain fused metal crowns is non-existent.
- Provides non-sensitivity to heat and cold due to non-electrical conductivity property.
- Stronger teeth and natural looking aesthetic appearance.
- Promotes gum tissue re-generation.
- Minimal tooth structure is removed.
Procedures
- Consultation and X-Ray.
- Preparation of the tooth by removing a small amount of tooth structure.
- Taking an impression of your tooth. This is done by a mould filled with dental putty which you will be asked to bite into. The impression will be sent to a dental lab where your crown will be fabricated. This might take a few days. Your dentist will let you know the exact day after taking your impression.
- Placement of a temporary crown until your zirconium crown is ready.
- Fitting and bonding of your permanent crown when it is ready. Your dentist will give it a final clean and polish.
