Types of dental crowns and their differences

Many patients are seized with panic when they learn about the need to put crowns on teeth. But is it really so scary? Let's take a closer look at the types of teeth crowns, their features and installation method.

Types of dental crowns

Our dentistry in Riga offers patients 3 types of teeth crowns:

1. Ceramic-metal crowns

2. Zirconia crowns

3. Ceramic crowns (Porcelain crowns)

Each material has its own unique properties and features, but all have one goal - to restore the chewing function and aesthetic appearance. So, what is the difference between various materials?

Degree of turning

Ceramic-metal crowns

The installation of a ceramic-metal crown has its drawback, namely, the almost complete turning of a native tooth. Metal crowns are the toughest material that requires deep tooth turning (up to 2 mm on each side) and nerve removal. Due to this procedure, the teeth become very brittle over time and even break.

Zirconia

Zirconia crowns require a lesser degree of turning, and this eliminates the need for depulpation.

Ceramics

Ceramic crowns are the most sparing option, because tooth turning in this case is minimal. So you can save not only a healthy tooth, but also its aesthetic appearance.

Aesthetics

Ceramic-metal crowns

Porcelain Fused to Metal crowns does not have a high level of aesthetics since the base of the metal can be translucent. And this will not play the best role in the beauty of your smile.

Zirconia

Since zirconia tooth crowns do not have dark metals in their composition, the level of aesthetics is significantly increased. Also, a zirconia crown can be made with the addition of ceramics, which will make it even more attractive.

Ceramics

Porcelain crowns have the highest degree of aesthetics. None of the above materials can be compared with ceramics in appearance. They are almost like veneers. Ceramic crowns are quite thin, completely cover the tooth, and also have a color that is as close to natural as possible. But the difference between crowns and veneers, in this case, rests on sensitivity. Due to the strong chemical treatment during the installation of veneers teeth can become very sensitive, and it can last from 1 to 4 months. There is no such problem with crowns.

Durability

Ceramic-metal crowns

Despite the fact that cermet has recently become less and less popular due to aggressive tooth turning, the service life of ceramic-metal crowns crowns can vary from 10 to 15 years and above. Therefore, some patients still prefer to install ceramic-metal crowns, the price of which is much lower than that of followers.

Zirconia

If you are faced with a choice of zirconia or metal-ceramic crown, then zirconia will win in strength. Zirconia crowns are currently made of the highest strength material. These crowns can last up to 20 years, and without losing their aesthetic properties.

Ceramics

Despite the advantages in terms of aesthetics, ceramic crowns cannot boast of distinctive durability. Also, it will not be possible to make a teeth bridge out of ceramics, since it can burst. Most often, they are placed only on the front teeth, since ceramics can break if neglected. With proper care, porcelain crowns can last you up to 15 years.

How many crowns need to be installed?

Depending on what goals you pursue, the number of crowns is calculated.

To correct the smile, it will be enough to put 4 dental tooth crowns, but it is worth considering that in this case there are certain boundaries. Correcting a smile, crowns can only change the appearance of the teeth, but it will be impossible to increase the length or width of the teeth.

We strongly do not recommend installing 6 crowns, since due to the fact that the lateral teeth are more massive, your smile will look disproportionate.

 To completely reconstruct the smile, you will need to install 8-10 crowns. Here, the doctor will already be able to expand the lateral borders of the teeth, vary the proportions and even the length.

But if you decide to make a total rehabilitation of the upper and lower dentition, then you need to install over 14 crowns. Here you can change not only the look of the smile but also the functionality of the teeth, for example, change the bite within certain limits. Also, with total rehabilitation, you can combine crowns with dental implants or veneers.
