Zirconium Crowns
A crown is a tooth-shaped covering that completely encases the visible part of the tooth.
Zirconia or zirconium is the strongest material used in dentistry.
Also Zirconium is a very hard white ceramic that comes in the form of solid blocks of various shapes and sizes.
Ceramic crowns are crafted in a lab and built up layer by layer. This gives them the same slightly translucent appearance of natural teeth and makes them a popular choice for front teeth that will be on show.
Steps of ementation of zirconium crowns.
The first step is where your teeth are assessed and measured for a crown. The dentist will discuss the procedure with you before preparing your crown of tooth.
A mould is made with dental putty which you have to bite into. This mould is used as a guide for the production of your new crown at a dental laboratory.
The second step is where your tooth will be fitted with your new crown. The dental crown procedure involves removing a significant amount – sometimes all – of the existing tooth enamel, so the crown material can be securely fitted. The tooth which will encircle this crown is roughened with a special dental acid which scratches the surface and increases the bond between the crown and a tooth.
After that, the crown is then fitted onto your tooth. The dentist will check its appearance and fits before cementing it into position. When the crown is fitted, then wıll be given a final polish.
Next, the dentist takes an impression of what’s left of the tooth, so the crown can be created to fit it perfectly.
How long does it take to fit zirconia crowns?
It can take 2-3 weeks for the crown to be made in the specialist lab, so the dentist fits a temporary crown (made from composite or acrylic) to stop any sensitivity in the tooth.
The colour of the temporary tooth crown should blend in with your natural teeth, but the material and finish aren’t as high-quality as the permanent crown will eventually be.
It’s at this point that your dentist will also choose the shade for your crown, if you’re getting it, made in a material to match your teeth.
A zirconia crown must be cared for in the same way like your natural teeth.
If you have any concerns about the colour or shape of the permanent crown (especially for a front tooth crown), be sure to speak up before it’s cemented. It’s difficult to make any changes once your new crown is in place, and you’ll have to live with it for a long time!
