Zirconia Crowns


Zirconia Crowns – the best choice?

Are you curious to know what an zirconia crowns is? Do you want to discover if zirconia crowns are the right choice for you? Well, you’re in the right place, considering that you can find much confusing information on the web and it can be hard for you to understand exactly how this tecnology works and if is a good choice. Here you’ll find the the right information you need to make the best decision, when deciding if zirconium crowns are the right choice for you, or not.

It’s known that for years, people that have had dental crowns put in have had to deal with the unsightly grey or black line along there gums that develops from porcelain-fused to metal crowns. This effect is caused by low quality metals, but within the last few years, there have been many advancements in cosmetic dentistry, so you can relax and smile wide.

One of the new technology in dentistry is zirconia crowns, a material that is so strong that it can be used anywhere in the mouth, with more trust considering that with zirconia crowns that unsightly grey or black line which developps along the gums will be just an ugly memory.

What is a crown and what materials are used for its fabrication?

However, for those who aren’t familiar with the concept let’s first define what is a dental crown: A crown is a dental restoration that completely covers or surrounds a tooth or dental implant. The crown is usually fixed to the tooth using traditional dental cement, but other materials can be used for this operation.

In order to fabricate the crown, the dentist can choose from a wide range of materials, using, in general, the out-of-mouth method. Considering that crowns are frequently used to improve strength or appearance of teeth, the materials used for this must meet two important requirements: to be strong and aesthetic and this are: full-porcelain (ceramic) dental materials include porcelain, ceramic or glass screen fillings and crowns (aka jacket crown, a metal free option).

One of the most common material used for the new crowns is porcelain, but the full porcelain can chip or break and this is not a desirable situation. However, the full porcelain is defeated by a much better solution: the crowns are made of metal zirconia, then merge the porcelain on the outside. Why is this a better solution? The answer is very simple: zirconia metal gives the strength while the porcelain gives the appearance of a normal tooth.

Why should I choose zirconia crowns?

Fist of all, you should take into account that the look of zirconia crowns is very close to natural teeth fulfilling even the most demanding requirements and 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. Well, this main quality makes zirconium crowns very one of the best choices within dental work.

How can it look so natural? By using crowns made of metal zirconia, then merge the porcelain on the outside, zirconia crowns allow light to pass as a normal tooth would and that gives a natural look, unlike other metal cores that are block the light.

Secondly, you must know that the normal too hot/cold sensations you can feel with other crowns does not normally occur because of the lack of electrical conductivity, this being another strong point for zirconia.


What is the procedures?

Whole process is quite complicated, but we will try to simplify it so that it is understandable. In order to accommodate the new zirconia crowns, a portion of your natural tooth’s structure is removed.

This step is followed by fitting a temporary crown that will be installed between visits. During this process, the custom zirconia crowns are made in specialized dentistry laboratories, besed on the impression taken of the original tooth.

Following this, when the new zirconium crowns are completely and ready for the final fixing, the temporary crowns are removed and your new custom zirconium crowns are securely fiitted in the right place, improving your smile and also your life.


It’s time for a short overview…

When you’re on the chair of your dentist you shoul remember a couple of important thigs that make the difference: not only that zirconia crowns won’t corrode, but the normal black gum line that you can see around a porcelain fused metal crown, won’t happen because of the strong ceramic material used. In addition to that you should keep in mind that the normal too hot/cold sensations you can feel with other crowns does not normally occur because of the lack of electrical conductivity.
