Basic varieties

Metal crowns is the first variety of such products.They are still used today 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.To create metallic types of crowns, platinum, gold and precious metals or their spraying are used.Appearance of such products leaves much to be desired, so they are installed less and less.
Ceramic ceramic dental crowns are considered to be quite strong.Their outer part is made of ceramics, and the inside is made of metal.Nevertheless, such crowns are inferior to all-ceramic, because in some cases a metal bezel can be seen.You can see it by looking at the corresponding photo.To avoid such an aesthetic defect, it is necessary to use zirconia to manufacture the product.Such crowns look much better.
Ceramic prosthetics , which are often found in the photo, are considered the most expensive and aesthetic in appearance.Pottery is distinguished by 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 the front teeth.It should be noted that for chewing teeth it may not be strong enough.
Metal plastic crowns are designed for temporary prosthetics.Most often, this type of prosthesis is installed on implants, but it can also be used as a bridge prosthesis.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 darkening of color, fragility, poor adherence to the metal frame, as well as the translucence of metal.
The plastic crown is designed for temporary prosthetics.Its advantages are affordable price, fast production and ease of material.

What determines the cost of the crown?

The pricing in the various dental centers depends on a number of factors of .These include:

Pricing policy.So, any clinic is focused on a certain segment of patients with a specific income.
Qualification of the personnel.This applies especially to the orthopedist, who examines the patient's teeth, removes the casts, and also selects the shade of the dental crown and fixes it.In addition, the qualification of a dental technician, who directly produces the crown, is always taken into account.
Cost of materials.In some dental centers only high-quality imported ceramics is used, while in other clinics domestic material is used that is affordable at affordable prices.
Availability of own laboratory.The preparation of the dental crown is carried out only in the dental laboratory, which is not presented in every clinic.Therefore, management is forced to sign contracts with such laboratories, which directly affects the cost of services.

When going to the dental center for the installation of a dental crown, many patients pay attention only to the price, because for some, this is the only decisive factor for when choosing a clinic.However, it must be remembered that institutions that offer attractive prices, and themselves save on something.Most often it is the hiring of low-skilled or inexperienced personnel.

Some clinics use the cheapest material of domestic production.Naturally, because of this economy, the finished tooth crown may not fit properly.In addition, cheap ceramics are not transparent enough.Also, the probability of chipping increases.When using poor-quality alloys in the metal, cracks may appear, due to which the dental crown must be changed.

Manufacture and installation of

Production of dental crowns In the clinic specialist makes an impression from the jaw of , thanks to which it is possible to make a prosthesis taking into account all the anatomical features.Then in the laboratory cast a plaster model, which accurately copies the teeth of the client.Using a wax, a sample of the crown is modeled and a metal frame is created.After fitting and choosing a shade of teeth, the product is covered with ceramics.

In the process of making a dental prosthesis, a temporary crown is established for the patient.It is carefully fixed with special cement.

The installation of the permanent prosthesis is carried out in stages:

First the doctor carefully examines the oral cavity, as well as the completed X-ray.If any problems were found, the channels are sealed and the treatment required.
Next comes the preparation of the tooth, that is, its grinding.At the same time, small ledges are performed in the lower part.
In some cases depilation is shown.
If there is no top part of the tooth, a special metal overlay is installed, which will ensure a reliable fixation of the crown.Also, if necessary, the pin is installed.
After fitting the design and choosing a shade, the dental crown is fixed with a special cement.

Service life and care

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

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

It should be remembered that the prosthesis is removed most often because of various problems with the teeth.So, after 1-1,5 years after prosthetics, inflammation of the dental root is often noted, in which there is swelling of the gums and an unpleasant smell.

In order for the product to last as long as possible, the must be properly serviced by .So, if only single crowns were installed, an ordinary dental floss and a brush with paste would be suitable for cleaning.In the presence of a bridge, the use of an irrigator is shown, with the help of which the remnants of food and plaque are removed.In addition, you should visit the dentist once every six months.

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 you can not change these parameters.
When prosthetics is complete, at least needs to sit for half an hour in the clinic.This will help to make sure that the design is really well seated.If there are any problems or inconveniences, you can immediately go back to the doctor's office.
Before leaving the clinic, it is necessary to clarify the rules of oral care and ask for a contact number of the dentist, so that in case of questions or problems to be able to contact.
