  • Chewing teeth without nerves are covered with special orthopedic crowns. This helps to avoid possible chips and fractures. It is also necessary to remember that in the absence of a nerve the tooth becomes too fragile.
  • Various aesthetic defects, especially changes in the shade of enamel due to tetracycline treatment, hypoplasia, fluorosis.

Main varieties

  1. Pros and cons of crownsMetal crowns - This is the first kind of similar products. Today they are used in dentistry, which is explained by their affordable price. The reason for the low cost is the possibility of using various alloys in the manufacturing process. It can be stainless steel as well as titanium. Platinum, gold and precious metals or their deposition is used to create metal types of crowns. The appearance of such products leaves much to be desired, so they are installed less and less.
  2. Metal-ceramic dental crowns considered pretty durable. Their outer part is made of ceramic, and the inner part is made of metal. Nevertheless, such crowns are inferior to all-ceramic, because in some cases a metal rim can be seen. You can see this by looking at the appropriate photo. To avoid such an aesthetic defect, it is necessary to use zirconia for the manufacture of the product. These crowns look much better.
  3. Ceramic prostheses, which are often found in the photo, are considered the most expensive and aesthetic in appearance. Ceramics have the necessary level of transparency and the possibility of selecting a shade that matches the color of the patient's enamel. Moreover, this biocompatible material is ideal for front teeth. It is worth noting that for chewing teeth it may not be strong enough.
  4. Metal plastic crowns intended for temporary prosthetics.Most often, this type of prosthesis is installed on implants, but it can also be used as a bridge. The service life of the product is 1-3 years. The only advantage of a metal-plastic crown is its affordable price. The disadvantages include the darkening of color, fragility, poor fit to the metal frame, as well as translucency of the metal.
  5. Plastic crown designed for temporary prosthetics. Its advantages are reasonable price, fast production and ease of material.

What does the cost of the crown?

Pricing in various dental centers depends on many factors. These include:

  • Types of dental crownsPrice policy. So, any clinic is focused on a specific segment of patients with a specific income.
  • Staff qualifications. In particular, this concerns an orthopedist who examines a patient's teeth, makes impressions, and also picks up the shade of a dental crown and fixes it. In addition, the qualification of the dental technician who is directly involved in the manufacture of the crown is always taken into account.
  • Cost of materials. In some dental centers, only high-quality imported ceramics are used, while in other clinics, domestic material is used, which is distinguished by an affordable price.
  • Having your own laboratory. The manufacture of a dental crown is carried out only in a dental laboratory that is not represented in every clinic. Therefore, management is forced to sign agreements with such laboratories, which has a direct impact on the cost of services.

Going to the dental center to install a dental crown, many patients pay attention only to the price, because for some it’s single decisive factor when choosing a clinic. However, it must be remembered that the institutions that offer reasonable prices save themselves on something. Most often this is the recruitment of low-skilled or inexperienced staff.

Some clinics use the cheapest material of domestic production. Naturally, because of such savings, a finished tooth crown can fit poorly. In addition, cheap ceramics are not transparent enough. Also increases the likelihood of chipping. When using low-quality alloys in the metal may appear cracks, because of which the dental crown will have to be changed.

Fabrication and installation

Dental crown makingIn the clinic specialist makes a copy of the jaw, thanks to which it is possible to make a prosthesis with all the anatomical features. Then a plaster model is molded in the laboratory that accurately copies the client's teeth. Using wax, a crown pattern is modeled and a metal frame is created. After trying on and choosing a shade of teeth, the product is covered with ceramics.

In the manufacturing process denture a temporary crown is placed on the patient. It is carefully fixed with special cement.

Permanent denture installation performed in stages:

  1. First, the doctor carefully examines the oral cavity, as well as performed an X-ray. If any problems were found, the canal filling and the necessary treatment are performed.
  2. Next comes the turn of tooth preparation, that is, its grinding. At the same time in the lower part there are small ledges.
  3. Depulping is indicated in some cases.
  4. If there is no upper part of the tooth, a special metal lining is installed, which will ensure reliable fixation of the crown. Also, if necessary, the installation of the pin.
  5. After fitting the design and selecting the hue, the dental crown is fixed with the help of special cement.

Service life and care

The durability of the prosthesis depends on various factors. This includes the quality of the material used, the correct implementation of the metal frame, the condition of the oral cavity and compliance with care recommendations.

  • How long will the implants last?The service life of metal crowns is at least 25 years.
  • Metal-ceramic crowns serve an average of 10 years.
  • Constructions that do not contain metal are suitable for 5-10 years.

It must be remembered that the prosthesis is removed most often due to various problems with the teeth. So, after 1-1.5 years after prosthetics, inflammation of the dental root is often noted, with which there is swelling of the gums and an unpleasant odor.

To make the product last as long as possible, you need to properly care for him. So, if only single crowns were installed, a regular dental floss and a brush with a paste would be suitable for cleaning. In the presence of a bridge, the use of an irrigator is shown, which removes food debris and plaque. In addition, you should visit the dentist every six months.

What the patient needs to know?

  • Consultation with a dentistGoing to the reception for installation denture, you must, above all, calm down. An hour before visiting the dental office you need to eat well.
  • If the first visit is planned, then better to arrange in the morning. This is explained by the fact that with natural light it is much easier to determine the true color of the enamel, so that in real life and in the photo the difference was not noticeable. It is also necessary to prepare any pictures of the teeth that are on hand, and to take with them old dentures.
  • In the office, you must carefully listen to the doctor, who will talk about the various options for prosthetics. You should not be afraid to ask any questions. Before deciding on a suitable variant of the dental crown, the time and cost of prosthetics should be clarified. Ideally, the doctor should give the patient a treatment plan. Separately, you need to specify the warranty period.
  • The best thing consult several doctors at once. If one specialist assures that everything will be fine, and another indicates possible problems, it is better to prefer a second dentist.
  • It should be remembered that if you pay the full cost of treatment in the event of a conflict, you will most likely not be able to return part of the funds or the full amount. Therefore, it is recommended to make payment in stages.
  • Immediately before installing the dental crown, it is necessary to check the transparency of the product, its shade and shape. This is very important, because after fixing, these parameters cannot be changed.
  • When the prosthesis is completed, at least half an hour to sit in the clinic. This will help make sure that the structure is really well fitting. If there are any problems or inconveniences, you can immediately return to the office to the doctor.
  • Before leaving the clinic, it is necessary to clarify the rules of care for the oral cavity and ask the contact number of the dentist so that in case of questions or problems you have the opportunity to contact.

Choosing a dental crown, you can not think only about the cost or aesthetics. So, expensive ceramic products are best suited for the front teeth, and for chewing - cheaper metal-ceramic prostheses.
