Crowns on teeth are an orthopedic design, which is manufactured in the laboratory. They cover the teeth on all sides, then are fixed with a special cement. Ceramic crowns - one of their varieties, it is widely used today in dentistry.
Appointment of crowns for the front teeth
Front teeth are a business card of a person, the impression made on other people depends on their appearance. Therefore, many attach great importance in their treatment of the aesthetic side of the issue.
The crown in this case plays the role of a new tooth surface, with its help, the destroyed areas are restored, the shape and appearance are given. They are installed when it is impossible to reconstruct the tooth through fillings or inlays. They are also needed in cases where therapeutic treatment has been ineffective.
Classification
On the front teeth set crowns based on ceramics, metal or cermets. We will focus on the description of the first group and the benefits of this kind.
So, the metal-free ceramic crown, in comparison with the other two, has a more attractive appearance and acts as their worthy alternative.
The frame for it is chosen strictly by color, and only then a special mass is applied. Ceramic crowns put on the front teeth much more often than on the side.
Varieties
Ceramic crowns vary in composition. Photo samples you can see in this article. In particular, from a material based on zirconium. Such products are very durable, aesthetic and well compatible with the oral cavity. Zirconium oxide has a white matte finish. Ceramic crowns of this type are made by computer milling, and this guarantees maximum accuracy and durability. They are also good in that no metal edge is visible in the gum area.
In addition, there is such a variation as Ips Empress. These ceramic crowns are pressed on the basis of glass. In this system, an increased percentage of leucite (crystalline substance), which increases the strength of the structure.
They are used as linings and inlays for chewing teeth and single designs for anterior teeth.
Also, all species have an attractive appearance. This is a characteristic feature of such a design as a ceramic crown. The photo before and after their installation clearly shows what aesthetic role they play. Below we consider what they are depending on the application.
Veneers and Tabs
According to the purpose, a different ceramic crown per tooth can be used. Photos of the samples may not reflect this externally, but the tabs from the veneers will be different.
What are their features?
Veneers are ceramic pads that are used to correct the front teeth. They improve their appearance and eliminate defects, for example, the
gap between the teeth.Tabs are mini-prostheses that are designed to level out minor damage. In particular, they are suitable if a third of the tooth has collapsed. They are strong enough and more dense than ordinary fillings. Also, they do not sit down and they do not have micropores that can allow the re-emergence of caries. They are made in a special laboratory for blanks-casts. Then they are fixed with dental glue.
The advantages of ceramic designs
First of all, it is aesthetically pleasing. Ceramic crowns on the front teeth, the photo of which is attached to this material, are not equipped with a metal frame. Therefore, light passes through the material, and due to this, they look as natural as possible.
Ceramics is applied in layers, this increases the depth of light absorption of the structure, it does not stand out against the background of healthy teeth.
Desna retains its appearance, while not becoming inflamed and darkens. And the crowns themselves do not darken due to the use of tea, coffee or food additives. Also, the material is able to protect the oral cavity from allergies, there are no characteristic unpleasant sensations, tastes and irritations.
Among the advantages, it is possible to highlight the possibility of preserving the pulp under the crown, its lightness and ease of manufacture and installation.
Cons of ceramic crowns
Of course, they have much more positive aspects. But before installing ceramic crowns, you should familiarize yourself with their disadvantages. They are recommended to be installed on the front teeth; their life is limited to approximately 10 years.
Some species are made for a long time, but, as a rule, the result is worth it. Also, if the structure breaks, complex repairs are required.
Is it possible to install crowns at a time?
In some cases, in individual clinics, it is possible to quickly manufacture and install ceramic-based structures. All this is possible through the use of special grinders.
First, a bad tooth is prepared. The crown is made within half an hour, then it is placed. Under normal circumstances, this is done in two visits. In this case, the crown is made using standard equipment for two weeks.
Production technology
Ceramic crowns for teeth are made in different ways. It all depends on the clinic and the financial capabilities of its visitors. The most common four technologies:
- firing (refractory model, or platinum foil);
- whitening and lining of the frame;
- pressing using patented technologies;
- computer milling.
Stages of work during pressing
The pressing of ceramic structures, according to EMPRESS technology, is one of the most progressive methods for their production. It includes such stages of work:
- an appointment with a dentist with subsequent consultation regarding methods of getting rid of defects and prosthetics, agreeing on the timing and cost of work;
- preparation of the oral cavity, treatment of supporting teeth (if necessary) and their grinding;
- production of dentofacial mold;
- sending it to a special laboratory, where it serves as the basis for the manufacture of a wax model for the future crown;
- the formation of a ceramic structure with its help. The mass is first heated to a temperature above 1000 degrees. Then it is pressed into a mold so that the crystals fit snugly. This provides better strength;
- stage of firing and adjustment - the structure is covered with several ceramic layers;
- installation of the prosthesis taking into account minor adjustments (if necessary);
- fixing with cementitious adhesive.
Installation cost
A logical question for a potential patient will be: how much does a ceramic prosthesis for anterior teeth cost? It is worth saying that it will not be able to do cheap, like a regular metal-based one. The material is of high quality, which can not cost a little.
The cost indicated by the clinic usually includes the following:
- the complexity of the work;
- expendable materials;
- depreciation of equipment used;
- qualification of specialists.
Depending on the type of construction based on ceramics, its cost will be from 10 to 50 thousand rubles. At the same time, it is highly advisable to focus on the available reviews before choosing a particular clinic or doctor. This will allow you to choose a good specialist who will perform the work qualitatively.
Ceramic prosthesis patients
Perhaps not everyone fits with ceramic crowns. Reviews about them are mostly positive, but it is better to talk with a specialist before installation.
Many patients are very pleased that in this way they solved the aesthetic problem, when the mouth was full of fillings and the front part did not look very beautiful. This option allows you to brighten up the problem and mask everything under healthy and
beautiful teeth.Basically, patients note the naturalness and shade of the design, the absence of uncomfortable sensations and side effects. However, the installation of prostheses requires proper care. In particular, this applies to the consumption of solid products. If you do not expose them to heavy loads, then the crowns will last quite a long time.
One of the significant disadvantages of this solution is its high cost. But taking into account the work, materials and the result, even it is completely justified.
How to care for pottery
If you want your new ceramic crowns to last as long as possible, you should look after them. Hygiene methods are not different from those that relate to natural teeth.
As already mentioned, particles of solid food must not be allowed to enter crowns or inlays. In addition, it is necessary to thoroughly clean the interdental spaces using dental floss. All this is not so difficult, but thanks to this, your next visit to the dentist on the crown issue will not happen soon.
Despite the fact that they have a relatively short service life, with proper care it can be extended up to 10 years. And this is taking into account the fact that we are talking about front teeth.
Ceramic-based crowns are the best option for anyone. They look beautiful and help hide tooth imperfections. It is possible that their installation may seem like an expensive pleasure, but if you compare all the advantages, then this cost will be justified.
