Crowns on the teeth: how to put and what? Which crowns are better

People often resort to the installation of crowns for various injuries or defects in the dentition. They help to save even the most unattractive smile from an aesthetic point of view. Fortunately, the age of the crowns "under gold" remained far behind. Today, dentists use other materials in their work. This article provides information about what kind of crowns are on the teeth, how they are put, how much the procedure itself costs.

general information

Crown is a non-removable design that allows you to remove all existing defects. Prostheses of this kind are used to make the tooth more durable, restore its shape and size, and also to create resistance to chewing loads.

Very often crowns are part of one large prosthesis. For example, when several teeth are missing at once and need to be fully compensated for by artificial ones. In this case, the entire structure serves as a support on the adjacent teeth.

Is it painful to install crowns on teeth? How do they put such prostheses? As practice shows, many dental procedures are associated with uncomfortable sensations that are remembered for life. However, when installing crowns, the most unpleasant is only the first stage, when the specialist sharpens the tooth. Of course, modern dentistry has all the necessary anesthetic drugs, which are actively used in practice.

Despite all the above advantages of such a prosthesis, many still have the question of whether to put the crown on the tooth. Below we list the main indications for such a procedure:

1. The natural crown is destroyed due to trauma or developed carious process, but the root itself is preserved and can fulfill its primary function.
2. The smile looks unaesthetic due to defects in the shape or color of the enamel.
3. With periodontal disease, there is sometimes a risk of self-loosening of the teeth. In this situation, the installation of temporary crowns is recommended until the time of full recovery.
4. There is a pathological abrasion of the enamel.

Currently, dentistry can offer several options of dental crowns, which are made of different materials and characterized by certain properties.

Metal crowns

What kind of crowns on chewing teeth is best to put? Many experts suggest metal constructions, because they have a lot of advantages, and their cost is relatively low.

This variant can be made of different metals. Metal crowns are a classic example of prosthetics and have been used for several decades. The most common option - teeth "for gold."

The main advantages of such crowns are durability, reliability and durability. The elements are practically not subjected to the oxidation process, and the index of their abrasion is maximally correlated with natural enamel, so the antagonist teeth are not damaged during chewing. The disadvantage of this design is only one - an unaesthetic appearance, so it is usually installed on an inaccessible area for outsiders.

Ceramic (porcelain) crowns

All-ceramic crowns are recognized as the most aesthetic. They very accurately copy the natural surface of the teeth, without losing the primary properties after many years. What teeth are crowns made of ceramics? This material is brittle enough, it can not withstand a prolonged chewing load. That's why these prostheses are installed more often on the front teeth. The main disadvantage of this option is high cost.

Metal Ceramic Crowns

Metal ceramics combines the positive characteristics of metals and porcelain materials. This option is distinguished by its durability, strength, good aesthetic characteristics. The only drawback of this option is the preparation of teeth for the crown during the installation phase, a high risk of erasing the enamel.

Which option to choose?

When choosing a prosthesis should be based on indications for the installation of the structure, the wishes of the patient, his financial capabilities. The metal crowns are considered a budget option, but they are by far not the most aesthetic in terms of external indicators.

The metal-ceramic version is characterized by strength and naturalness, such a prosthesis can be placed on the tooth without removing the nerve. However, even with the slightest decrease in the gingiva, a gap can be formed between the crown itself and the tooth itself. In this case, its metallic bezel becomes noticeable.

The whole-ceramic version is as close as possible to natural teeth. It is characterized by functional endurance. If the financial possibilities of the patient are unlimited, it is recommended to install ceramic crowns on the teeth.

What are the best prostheses from the proposed options? Unfortunately, it is not possible to give an unambiguous answer to this question. Most experts in this area are still inclined to the latter option.

Preparing for prosthetics

The process of preliminary preparation for the installation of the prosthesis consists of several independent stages:

1. Determination of the clinical picture and assessment of the condition of the oral cavity. The doctor and the patient discuss the scope of the intervention, the cost of the crown on the teeth, which is better. A treatment plan is drawn up.
2. If necessary, the therapy of inflammatory diseases of the gums, caries, periodontium. All the old fillings on the so-called supporting teeth are removed and must be replaced without fail.
3. If the use of cermet is intended, a depulpation is prescribed to prevent the development of the inflammatory process.
4. Then the doctor prepares the tooth under the crown. This is a rather laborious procedure that involves the removal of hard tissues of a certain thickness by means of special tools. For a metal version, 0.3 mm of enamel is sufficient, when using cermet - 2 mm.
5. At the next stage special impressions are made with the help of paste. Subsequently, on their basis in the dental laboratory will be made crowns.
6. After the creation of the prosthesis, several primers are assigned, on which you can determine the accuracy of the final design, its convenience for the patient, and compliance with the color palette. Sometimes temporary cement is used to secure the crown. This is necessary so that the patient himself can make sure of its comfort.

Fixation of the crown on the teeth: how to put the prosthesis

• After removal from the temporary cement, the doctor thoroughly cleans the structure.
• Prepared in advance, the dental stump is treated with a special device to give the surface a small roughness.
• The final fitting is performed, during which the doctor is convinced of the correct location of the denture.
• Then, the crown is placed directly onto the tooth. On her inner surface, the doctor applies a certain amount of dental cement. The crown is extremely neatly worn on the tooth. After these manipulations, the structure is exposed to a special lamp to accelerate the solidification process.
• At the final stage, excess cement is removed, since even a small amount of a substance can provoke a strong irritation and inflammation in the gum area.
• After about 60 minutes, a small chewing load can already be applied to the crown.

Dental crown service life and warranty

The service life of competently made crowns is usually 10 years or more. However, in this matter, the quality of the initial preparation before prosthetics should be considered in more detail. In most cases, the tooth under the crown is depulpated, that is, all nerves are removed and the root canals are filled. This is the most vulnerable place in the procedure under consideration.

In 60-70% of cases, the root canals themselves are damaged poorly, which leads to the development of complications of an inflammatory nature, the need to treat the tooth again or even to remove it. Chronic inflammation, as a rule, begins to appear after the end of the warranty period (after about 1-1.5 years). In foreign clinics the situation is somewhat different. The guarantee for prosthetics, for example, in Germany is 3-5 years.

Reviews

In general, patients after prosthetics leave extremely positive feedback. This is possible if the doctor has taken into account all the indications / contraindications before placing the crowns on the teeth. What are the best prostheses to put? This issue also belongs to the competence of the dentist, on which the subsequent result is based. Particular attention should be given to the qualitative processing of teeth at the initial stage, correct fixation (was not overstated / understated bite).

Thus, in the case of performing the manufacturing technique, the patient can always hope for a positive result. It is important to choose the right clinic where professional specialists work. Unfortunately, today it is not so easy to do it. Most private medical institutions are aimed at maximizing profit, often by reducing the quality and cost of materials.

How to properly care for crowns?

If so-called single crowns are installed, dental floss, toothpaste and brushes are sufficient to care for them. In the case of bridges , difficulties with hygiene often arise, because they have a special intermediate part, under which bacteria usually accumulate.

In addition to the standard rules of hygiene, dentists strongly recommend the use of special irrigators. The work of this apparatus is based on the creation of a pulsating jet of water under pressure, which is continuously fed through the nozzle. Thanks to the irrigator it is possible to clear the accumulated food debris and plaque hard to reach the usual brush areas of the mouth.

It is desirable to visit the dentist twice a year for preventive purposes to check the condition of the entire structure and surrounding tissues.

Cost of crowns

More expensive ceramic crowns are usually placed on the front teeth. Their cost varies from 10.000 to about 15.000 rubles. A ceramic-ceramic crown for a chewing tooth costs cheaper (3.000-4.000 rubles). Undoubtedly, the total cost of prosthetics depends on many factors. These include the following: the materials used, the prestige of the clinic, the availability of its own dental laboratory, the qualifications of medical personnel, and so on.

Possible complications after prosthetics

After definitive fixation of the crowns, some complications arise in some patients:

1. Prosthetic stomatitis. It develops because of the increased pressure of the prosthesis on the surrounding soft tissues. Pathology causes a violation of blood circulation and subsequent dying of the mucosa at the interface with the crown itself.
2. Caries. This problem may arise due to poor oral hygiene or if the patient has refused to receive dental treatment during the preparation for prosthetics.
3. Crowns can provoke the development of an allergic reaction, which is manifested by a burning sensation in the mouth, rashes on the mucous membranes.
4. Galvanic Syndrome. It develops when there are prostheses made of different materials in the mouth.

The appearance of any of the complications described above requires immediate medical attention. Otherwise, the risk of tooth loss increases. In such situations, as a rule, the doctor removes the crown and performs repeated prosthetics.

Of course, when carrying out such a procedure, only the patient can decide which crowns to put on the teeth. What are better prostheses (material), the expert himself can prompt directly. In any case, you should listen to the opinion of the doctor, accurately follow all his recommendations. This is the only way to hope for a positive result and to enjoy the work done well.
