Prosthetics of teeth with a metal-ceramic crown: the price, advantages and disadvantages, features of the installation of cermets

So, today, about 50 types of alloys and 100 varieties of ceramics are used to make crowns, which affects the cost of prosthetics.

All metal-ceramic crowns are divided into several subspecies:

• Classical metal ceramics.Here is a nickel-chrome frame, as well as low-cost, highly mineralized ceramics.Such a product is considered to be budgetary.Its advantages - affordable price and acceptable aesthetics , however, the alloy itself is considered highly allergenic.Thus, approximately 30% of patients have an allergic reaction.In addition, there is a high probability of cleavage of the ceramics and gingivitis of the gums.The cost of such a crown is on average 2.5-4.5 thousand rubles.
• Metal clay made of chromium and cobalt alloy.Such material is considered less allergenic.The design is more durable due to the use of synthetic ceramics.Despite the advantages of this kind of crown on teeth, the price of which is about 7 thousand rubles, does not exclude the possibility of gingival gums caused by oxidation of the edge of the carcass.
• Metal-ceramic crown with shoulder mass.This is the most aesthetic option, created from an ignoble alloy.Most often, chromium and cobalt are used.The edge of the finished product is resistant to stresses, so that the oxidation of the metal is practically not observed.
• Ceramic metal from a noble alloy.To create such crowns, palladium and gold are used.The advantages of the product are durability, aesthetics and non-oxidation.

Installing the crown

Preparing the tooth before the prosthesis.

1. First specialists make an X-ray, thanks to which it is possible to make sure that the tip of the tooth has no changes.If an inflammation has been found, appropriate treatment is prescribed.In the case where the channels were previously sealed, the X-ray helps determine the quality of the work.Sometimes you have to re-fill.
2. The next step involves performing a depulpation, that is, removing the nerve.In other words, the canal is sealed.Such procedure is carried out in case of detection of inflammation.Nerves are also to be removed in living anterior teeth.
3. If in the process of inspection caries or a poor-quality seal was noticed, appropriate treatment is performed.
4. If the tooth crown is destroyed by 50% or less, pin is carefully installed in the channel, and then the coronal part is restored using a filling material.
5. When the crown is completely destroyed or thin walls remain, a special tab must be installed.It ensures the reliability of the construction and protects the cermet from a serious load.

After the completion of the preparatory phase, prosthetics begins.First, the tooth is gently stitched.After that, the impression is taken.It is used for manufacturing in the laboratory conditions of a metal-ceramic crown.The process takes from 1 to 2 weeks.During this time, the patient walks with temporary crowns made of plastic.They help to protect spent teeth from aggressive external factors, and also make the smile more aesthetic.

Cost of metal-ceramic

Crowns made from Japanese or German ceramics, as well as high-quality alloy of cobalt and chromium, cost at least 6-7 thousand rubles.

Some patients prefer to save.They set crowns on teeth at a cost of 4-5 thousand rubles.For the manufacture of such a metal-ceramic , cheap materials of domestic production are used.

Crowns made of gold and palladium or platinum alloy cost from 9 thousand rubles.The cost of metal is not taken into account.

If temporary crowns were made for the patient, then about 1 thousand rubles is added to the cost of cermets.

Success of prosthetics

In order for the prosthetic procedure to be successful, a number of factors need to be considered.

1. Pre-preparation of the tooth.Many patients who have dentures are often faced with poor-quality canal filling.At the top of such teeth, the inflammatory process of is often noted, which leads to painful sensations and swelling of the gums.Accordingly, it is necessary to remove the prosthesis and to conduct repeated treatment.In some cases this leads to the need for tooth extraction.If the tooth was improperly prepared, then there is a possibility of breaking the metal-ceramic crown.
2. Professionalism of the orthopedist.In the process of prosthetics, much depends on the quality of the doctor's work.In particular, this concerns the grinding of teeth and the removal of casts.If the technology has been broken, a small gap will appear between the prosthesis and the tooth, where food particles and microorganisms will enter.This leads to decay of the tissues and subsequent breakage of the cermet.
3. Qualitative performance of works by a dental technician.Ready-made casts are sent to the laboratory, where the dental technician prepares the gypsum model and simulates the prosthesis itself.From the professionalism of this specialist depends on the final color and shape of the product.

Service life

In most dental centers, dental prosthetics are warranted for 1 year.The cermets themselves will last about 10 years.However, this only applies when the work was done at a high level.

Before the expiry of the warranty period, it is necessary to perform a control image of the teeth, even when the patient does not have any unpleasant symptoms.This is due to the fact that near the roots inflammation often occurs, leading to the need for treatment and re-prosthetics.If you notice such a defect before the completion of the guarantee, the treatment and installation of the prosthesis will be performed free of charge.Naturally, it is better to take a picture in another clinic, because some unscrupulous doctors do not want to alter the low-quality work and therefore hide the true state of affairs from the patient.

After the installation of the metal-ceramic crown, a regular visit to the doctor is recommended.Also important timely replacement of the prosthesis , which will help to avoid various problems, including splitting or falling out of the product.
