Solid crown: characteristics and types

Many of us at least once faced with or other problems of the oral cavity, respectively, turned to a qualified dentist for help. Thanks to modern casting technologies, the possibilities of dentistry are almost endless. One of the revolutionary inventions is a solid metal crown, with which you can restore any lost tooth of the jaw row. In addition, such crowns allow you to return the correct shape to the split tooth or to create a strong, reliable and durable support for the bridge structure.

general information

solid crownThe one-piece tooth crown is a structure made of metal, with which you can completely restore a lost tooth or part of it. In addition, a special casting technology allows you to create very strong bridges, in which the individual elements are not soldered to each other. Thus, bridges last much longer.

Varieties of crowns

Today, there are several varieties of solid crowns, each of which has certain features and is selected by a specialist individually for each patient, depending on his financial capabilities and the state of the oral cavity.

Solid crown can be:

  • without spraying;
  • with dusting;
  • with facing;
  • solid bridge construction.

To understand what each type of crown is, you need to elaborate on each of them.

Crowns without spraying

solid crownThe solid crown without spraying is a metal construction made of chrome or cobalt, which is polished to an ideal condition. Since no deposition is used in the manufacturing process, such crowns do not have an attractive appearance, so they are used to restore distant teeth that are not visible.

Crowns with a dusting

This type of crowns has a more aesthetic appearance, which is achieved due to the deposition of special materials applied to the metal alloy by the vacuum-plasma method.Depending on the type of spraying, the crown can imitate any precious metal.

Such a solid crown, the photo of which looks quite attractive, has excellent strength and durability, however, it does not look like a natural tooth, therefore the main area of ​​application of the crown with spraying is the replacement of teeth in the long-distance rows. In addition, it is necessary to take into account the fact that some people may have incompatibility with one or another type of spraying, so they may develop an allergy.

Crowns with facing

production of a one-piece crownThe solid-molded crown with lining completely imitates a natural tooth, so it is used to restore the lost first-row teeth, which are visible to others during a smile. High similarity is achieved due to a special patch made of plastic or ceramic, which is installed over the prosthesis.

The only drawback of this type of crowns is their large size, due to which an increased load is created on the artificial tooth, as a result of which the facing covering can be damaged, it often splits off or cracks.

Solid bridge structures

Solid monolithic prostheses are used by dentists in very difficult cases when it is necessary to restore several lost teeth located next to each other in the chewing area. These structures have high strength, therefore, are able to serve for quite a long time. However, there is one major drawback that should be considered when installing a prosthesis of this type. A solid cast bridge creates a very high load on the adjacent teeth while chewing food, as a result of which they can be damaged.

What materials are the structures made of?

solid metal crownThe production of a solid cast crown is made of high-quality metal alloys. The most common is a metal alloy consisting of chromium and cobalt or nickel.

More expensive crowns are made of titanium, because this metal has many advantages compared with other materials:

  • does not cause allergies;
  • retains its original appearance throughout the operation;
  • does not affect the acid-base balance of saliva.

Finished solid crowns, the manufacturing steps of which will be discussed further, can also be covered with a coating of titanium nitride, which gives the product a golden color, and also increases the strength and durability of the prosthesis. However, these crowns are much more expensive.

Indications

solid crown stagesDentists advise to install solid crowns in such cases:

  • loss of more than 70 percent of the dentition;
  • if you need to strengthen the teeth involved in the process of chewing food;
  • with a strong erasure of tooth enamel;
  • malocclusion;
  • low teeth height;
  • pathological gnashing of teeth;
  • involuntary contraction of the muscles responsible for chewing;
  • if you need support for the installation of the bridge.

To solve simpler problems related to the health of the oral cavity, other types of prostheses are used, which have a lower cost, however, in the cases listed above, only a one-piece crown can help.

Preparatory stage

Production and installation of crowns are performed in a certain sequence. It is very important to strictly adhere to it, since not only the quality of the product, but also its comfortable fit, as well as the durability of the structure, depend on it.

In the first session, the specialist determines the condition of the oral cavity in a patient in order to determine the presence of various pathologies and diseases. After that, a treatment program is drawn up, as well as the need to fill teeth. Also, a specialist negotiates with the patient the type of denture that is best to deliver.

When all the formalities relating to further treatment are settled, the dentist performs the preparation of the patient's tooth and makes it an impression, on the basis of which the whole crown will be made. In this case, a special silicone mass is used, which allows transferring the smallest features of a damaged tooth onto the mold and creating the perfect prosthesis. Next, the doctor sets the patient a temporary prosthesis that will speed up the process of adaptation and minimize any discomfort.

Prosthesis manufacturing process

solid tooth crownBased on the working impression, a solid crown is made.

Production steps are performed in the following sequence:

  • the tooth is extracted from a plaster cast, after which it is opened with a dental varnish;
  • in a special device wax is melted down to a liquid state;
  • plaster cast of a tooth is immersed in liquid wax for two seconds;
  • after the wax has hardened, the denture is given the desired shape.

After completing the process of modeling the product, it is given to the laboratory, in which the wax layer is replaced with a metal alloy or ceramic, then the quality of the prosthesis is checked. For very large problems with the teeth, an additional adjustment may be necessary, after which the finished crown can be installed.

Crown installation

When the solid-cast construction is completed, the dentist performs its fitting to match the size of the teeth, and also checks the strength of the product. To determine how the prosthesis will sit in its place, whether the patient will experience any inconvenience during chewing and bite, as well as how the body will react to a foreign body in the mouth, the doctor can make a temporary fixation.

If the patient has excellent compatibility with all materials, the temporary fixation changes to a permanent one. At the same time, the temporary cement with which the product is coated is changed to a permanent one, which has increased strength and durability.

Issue price

The amount to which the installation of a solid prosthesis will cost depends on the type of construction. Products without spraying will cost approximately 4 thousand rubles, and the cost of a crown with a dusting can vary from 4 to 7 thousand rubles, depending on the lining material. Installation of prostheses with a dusting will cost approximately 10,000 rubles.

Features care for crowns

No matter how expensive you put the crown, so that it lasts a long time, it is very important to follow the basic rules of hygiene. Brush your teeth in the morning and in the evening, each time rinsing the mouth with special means. It is also recommended to use dental floss after each meal.

If you find inflammation of the gums, it is recommended that you immediately contact your dentist, as this may lead to a failure of the fixation of the prosthesis.

Try to always monitor your teeth, and then you do not have to go to the dentists, and even more so to put the crowns.
