porcelain crownsThere are a variety of cosmetic crown which are made purely from ceramic and no other material. This is in contrast to other types of crowns like the porcelain fused to metal variety and gold crowns. The defining feature of these crowns is that the material they are made of is translucent, which creates a visually appealing look and blends in well with the rest of your teeth.

This implies a top quality crown which will last for many years. The majority of all ceramic crowns are produced using computer technology, e.g. CAD / CAM technology which is based on 3D design.

Another option is metal ceramic crowns.



Benefits of all ceramic crowns:

These crowns are perfectly suited to people who have minimal space inside their mouth for a crown and would like something which has a natural appearance. All ceramic crowns are made of a thinner material, which results in a lighter crown. Plus the material used is ‘bio-compatible’ which means it is gentle on the natural gum tissue and enables it to regrow next to the crown. There is no risk of an allergic response or sensitivity to hot or cold.

Disadvantages of all ceramic crowns:

Whilst there are advantages of these crowns it is only fair to highlight the disadvantages too.

There seems to be a trade off between aesthetics and strength: this type of crown is lifelike and pleasant to take a look at but there is a downside. It is less durable than other types of crowns which means it is more prone to cracking or breaking.

And the refinement needed to produce these crowns makes them more difficult to fit. They require a high degree of expertise on the part of the dentist which increases their cost.

How are all-ceramic crowns fitted?

The procedure is the same as for any fitting of a crown. The dentist will clean and reform the tooth in preparation. The tooth is reformed to taper so that it will allow the crown to fit snugly over the top.

An impression is then taken of your teeth with dental putty. This mold is sent to a dental lab where it will be used to fabricate a new crown. It takes around two to three weeks for the ceramic crown to be made, so you will be fitted with a non-permanent crown in the meantime.

Once the ceramic crown prepared a surgery will be scheduled where you will be fitted with your new crown. This entails the dentist roughing the outer surface of the affected tooth with etching acid which will enable the crown to adhere to the tooth.

Your dentist will check this bond. Once you both are satisfied with the fitting then it will be fixed firmly in place with dental cement. Take care of your new crown. There is research being undertaken into the longevity of all ceramic crowns so take every precaution not to put too much pressure on it. Be cautious when eating hard / crunchy foods and avoid grinding your teeth.
