Clinics offer many options for crowns, the key difference between which is the material of manufacture. It is on this parameter that the quality, cost and indications for the use of a particular crown depend to the greatest extent. Another very important nuance, which also affects the quality parameters, is the manufacturing technology of the product.

Types of crowns

1. Metal crowns. They are considered hopelessly outdated, but are still used in many clinics. They can be made from various alloys (cobalt-chrome, titanium, etc.). Possible options with sputtering (for example, "gold") or with plastic cladding. Manufactured using the one-piece casting technology: the structure is cast entirely according to the tooth impression. A stamping technique can also be used.


2. Crowns made of precious metals. As a rule, these are alloys based on gold or platinum. Crowns made of pure material are not used due to high cost and functional problems. The alloy allows achieving the required strength and maintaining biocompatibility. Manufactured using solid casting technology.


3. Metal-ceramic crowns.The most common products that consist of a metal frame and a ceramic coating. First, the frame is cast, then a layer of ceramics is applied, it is possible to manufacture it using computer simulation.


4. All-ceramic crowns.Metal-free ceramic crowns. Due to its biological inertness, this material is considered one of the safest for soft tissues. They are made using firing technology (on a refractory model or platinum foil); by pressing ceramics (surface painting technique or layering technique); on a milling machine using CAD / CAM computer modeling.


5. Some people consider such crowns to be metal-free products, but this is not the case. Zirconium is a metal, but much more aesthetic and safe than others. They are made by means of computer modeling on special milling equipment. There are two types of zirconium dioxide crowns: monolithic (completely made of zirconium dioxide without veneer) and combined (porcelain mass is applied to the zirconium dioxide framework).

There are also temporary crowns, which are placed during the manufacture of a permanent structure, but one cannot speak of them as a full-fledged orthopedic structure.

Each of these types of crowns has variations within its category (type of alloy, material characteristics, production method). The overall quality indicator consists of many nuances that must be considered when choosing a product. Below is a table with the main parameters that determine the quality of the crown. Two "plus" or two "minus" signs indicate a characteristic feature of the crown in a particular indicator.

Quality table

Product	Strength	Aesthetics	Durability	Price
Metal crown	+	– –	+/–	+
Golden crown	+	–	+	–
Metal-ceramic crown	+/–	+/–	+/–	+/–
Ceramic crown	+ (depends on the type of crown)	++	+	–
Zirconia crown	++	+	++	– –

All types of crowns are capable of restoring the functionality of the tooth, however, the advisability of choosing one or another product largely depends on the specific clinical case.

Which crown is better for a chewing tooth?

On the one hand, the answer to the question of which crowns are best for chewing teeth, is obvious. Molars are tireless laborers who bear almost the entire chewing load, so they need to be restored with very strong and reliable crowns. The issue of functionality really comes first, but you shouldn't dwell only on it. Despite the fact that molars are not as noticeable when smiling, it is simply criminal not to worry about aesthetics these days. In addition, the choice of the crown is also important from the point of view of the compatibility of its material with soft tissues.

Which crown is best for chewing teeth

• Metal crowns.These are reliable and cheap crowns with a good safety margin: the probability of breakage and chips is minimal. On the other hand, aesthetics will be at zero level with them. Another problem is individual intolerance to materials. If you are not ashamed of a "metallic" smile, then we advise you to install one-piece crowns of this type. Stamped products are not even the past, but the century before last. Loose fit, thin walls and the risk of bacteria accumulating under the crown - the list of disadvantages can be long listed.


• Gold and platinum crowns. They are not cheap (see the course on precious metals), but they are quite reliable, non-toxic and safe for soft tissues. The amount you pay for a precious alloy is quite comparable to the cost of a ceramic crown, and it looks much more like a natural tooth. However, in this case it is up to you to decide.


• Metal-ceramic crowns.The most popular option for dental restoration. The choice in favor of metal-ceramic is really justified, since it is these crowns that have the best price-quality ratio. However, this product has its drawbacks. Firstly, cermets are less durable than traditional metal crowns and are more prone to chipping. Secondly, the contact edge of the crown is not covered with ceramics, therefore, a blue stripe appears at the junction of the crown and gums, which is bad from the point of view of aesthetics. This problem can be partly solved (see crowns for anterior teeth), however, the funds spent in this case are not always justified.


• Ceramic crowns.It all depends on the type of crown. Classic ceramic crowns are not recommended for chewing teeth due to high risk breakdowns and chips, but today specialists have managed to significantly increase the strength of the material and improve the manufacturing technology. Modern crowns made of glass ceramics (Emax, Empress and similar) allow prosthetics in any part of the jaw. Their only drawback is a very high price (20,000 rubles or more for one product).


• Zirconia crowns. Very strong, very durable and very expensive. For the prosthetics of the chewing teeth, monolithic zirconia crownsbecause the porcelain veneer increases the possibility of chipping. The cost of one crown can go up to 25,000 - 30,000 rubles, which makes it practically unaffordable for many patients.

Which crown is best for the front tooth?

In the case of the front teeth, aesthetics come to the fore, since the incisors and canines are most visible when smiling. The main task of the crown is to look natural, not stand out from the rest of the dentition and have the necessary margin of safety. The question is which crowns are better to put on lower teeth (or on the upper teeth) does not make sense, since both the upper and lower jaw the same solutions are used.

Which crowns are best for front teeth

• Metal crowns.Install a metal crown on front tooth is to sign the death warrant with your smile. On the other hand, when there is no money at all for the restoration of teeth, even this option can be considered. There is also an alternative - a combined crown, the outer part of which is covered with plastic, and the inner part is covered with metal. However, you should not count on the durability of such a structure: the plastic is painted, erased and, in general, is not too resistant to the influence of the external environment.


• Crowns made of gold or platinum. A great option if you are a famous rapper, a gypsy baron, or just want to put together a Soviet fashionable set “Prosperous”: a sheepskin coat, fur hat, mohair scarf, mustache and gold “fix”. In all other cases, this option is meaningless.


• Sintered metal.An inexpensive, but very controversial option from the point of view of aesthetics. The metal frame shines through, not to mention the treacherous blue rim at the point of contact between the gum and crown. On the other hand, such a decision is an answer to the question of which crown is better to put on the front tooth if you are on a budget. To avoid the appearance of "cyanosis", it is possible to order metal-ceramic crowns with the so-called shoulder mass, when the entire area is covered with ceramics, but this option will cost about twice as much. For the same purpose, a frame made of gold or platinum is used, which also significantly raises the price.


• Ceramic crowns.Perhaps the best dental crowns for anterior prosthetics. Since the issue of strength is not so acute here, classic all-ceramic crowns, which are cheaper than more advanced glass-ceramic products, are quite suitable.


• Zirconia crowns.The most expensive option. If price doesn't matter to you, then zirconia-veneered crowns with porcelain veneers are a great option.

Tooth crowns: which are the best for the price?

The cost of crowns consists of materials, technologies and equipment used, as well as the qualifications of the doctor and the level of the clinic where the treatment is carried out. In the table below, you can see which crowns on the teeth are best placed, based on their cost.

Types of crowns for teeth and which ones are better in terms of cost

You can see all prices for dental crowns.

Dental treatment for caries and other diseases and plaque is carried out, canals are sealed. If necessary, tooth depulpation (nerve removal) is performed - as a rule, the patient undergoes this procedure when installing a crown on one of the front teeth, in order to avoid pulp burns. Then the tooth undergoes turning - the top layer of hard tissue is removed from it with a thickness equal to the thickness of the future crown. When grinding a living tooth, the patient is given local anesthesia.

2nd stage. Laboratory

After these manipulations, the dentist necessarily removes impressions from the dentition, with the help of the impressions, first plaster models are made, and then permanent crowns. During the manufacture of prostheses, the patient is fitted with temporary crowns made of plastic, which will hide the grinded teeth and perform chewing functions.

3rd stage. Fitting and installing a crown

Before installing the finished crown, a fitting must be done - in case of any inaccuracies and discomfort of the patient, the prosthesis will be finalized.

First, the prosthesis is installed for a period of time - from 2 weeks to a month. This is done in order to observe the reaction of the teeth to the prosthesis, to find out if there is any discomfort or malocclusion.

With the safe passage of this period and the absence of any complaints from the patient, the crown is installed on an ongoing basis.

Prosthetics services, installation of crowns in the dental clinic "US Dental Care"

Installing a crown on a tooth is a multi-stage process that requires high qualifications and practical experience of the dentist. In the American one in Moscow on Prospect Mira, equipped with the most modern equipment and technology, proven technologies and effective modern methods are used for treatment.

Our clinic employs high-class people who undergo regular internships and refresher courses, many of them specialize in prosthetics and perform brilliantly in this area.

A crown on a tooth is a non-removable structure that allows you to eliminate a tooth defect.The anatomical crown of a tooth can be destroyed.

In such situations, dental crowns are used to restore the shape, size of the tooth, give the tooth strength, as well as resistance to chewing loads.

They protect the teeth from further decay.

Anchoring crowns can be used to place bridges.

Indications

• Restoration of the tooth crown in case of its strong destruction (more than 50%).
• Increased abrasion of hard fabrics.
• To restore a lost tooth.
• Dental crown defects.
• Restoration of the anatomical shape and functionality of the tooth.
• Fluorosis.
• Anomalies of the teeth, manifested by the size or incorrect position of the teeth.
• Restoration of tooth aesthetics.
• A crown on a crooked tooth will help align it.

Contraindications

• Insufficient height of the preserved crown part of the tooth.
• Looseness of the tooth.
• Allergy to dental crowns.
• Malocclusion.
• Periodontal disease.
• Thinning of the walls of the lower anterior teeth.
• Age under 16.

Pros and cons

Pros of dental crowns:

• Aesthetics.
• Durability and strength depend on the material and manufacturing method of the crown.
• Affordability.
• Cast crowns do not require strong teeth turning.
• White ceramic crowns are ideal for anterior prosthetics.
• Ceramic crowns are biocompatible with tooth and gum tissue.
• The installed crown on the dead tooth prolongs its functionality.

Cons of dental crowns:

• Trauma to healthy teeth if they are used for supporting teeth.
• Depulpation under the crowns on the teeth can cause complications in the form of an inflammatory process.
• Ceramic dental crowns are not strong enough.
• Unaesthetic metal crowns.

Materials for making

• Modern dentistry offers a wide variety of materials for making dental crowns.
• For the manufacture of crowns, metal-ceramics, zirconium oxide, metal alloys, ceramics and other modern durable and hypoallergenic materials are used.
• Cobalt - chrome and cobalt - nickel alloys, as well as alloys of precious metals: platinum, palladium, gold, are used in the manufacture of metal-ceramic crowns.

Types of dental crowns

The types of dental crowns are classified according to the material used:

• Metal-ceramic dental crowns. Inner part The crown consists of a metal frame, which is veneered with ceramics on the outside. As a result, the structure is highly durable and aesthetically pleasing.
• Dental constructions made of metal-free ceramics. These crowns are made entirely of ceramic. The absence of metal improves the aesthetics of dental crowns. Crowns can be made of porcelain or zirconia. Metal-free ceramic structures are very durable, reliable in use and have a long service life.
• All-metal dental crowns. They can be solid, stamped, gold. The molar crowns can be made of metal, because they still do not fall into the smile line. It is not necessary to sharpen the tooth under such crowns.
• Metal-composite crowns are combined. They are made of cobalt-chrome alloy, and the outer surface is clad with plastic. Such crowns are also called metal-plastic.
• Dental crowns for implants.

Which dental crown is better

• When choosing the type of dental crown, it is necessary to proceed from the indications for the installation of the structure, the wishes and choice of the patient, as well as from his financial capacity.
• Metal dental crowns are made from alloys of metals, precious metals, or only with their sputtering. Metal cast crowns on teeth restore the chewing function of the tooth. But in terms of external indicators, these crowns are the most unaesthetic.
• Metal-ceramic dental crowns are characterized by strength and naturalness. Moreover, this type of dental constructions is inferior to ceramic crowns. On the positive side is that metal-ceramic crowns can be placed on teeth with not removed nerves. The disadvantage of the metal-ceramic design is that with the smallest decrease in the gums, a gap is formed between the crown and the tooth, and the metal rim of the dental crown becomes noticeable.
• All-ceramic dental crowns are the closest option to natural teeth. Differ in functional endurance. Ceramics from all of the above materials are highly biocompatible.

How is it made

After preparing the teeth for prosthetics, the following is performed:

• Taking casts from both jaws. The impression is made in order to be able to accurately manufacture the crown, taking into account both the adjacent teeth and the antagonist teeth. For making casts, a special impression mass is used.
• In the dental laboratory, a model of teeth from plaster is cast from the impression, which is an exact copy of the patient's teeth. On it, a sample of the future dental crown is modeled from wax.
• During the manufacture of permanent crowns, temporary ones are made. They are fixed to the tooth with a special cement that allows them to be removed before the permanent crowns are installed.
• A metal framework of the crown is made, which, after trying on and clarifying the color of the teeth, is covered with ceramics.

Installation steps

To install the structure, it is supposed to prepare a tooth for a crown:

• Visual examination of the tooth with an obligatory direction for an X-ray. If necessary, the required treatment and canal filling are carried out.
• To prepare the tooth for placing a crown on it, the tooth is prepared under anesthesia. Grinding teeth for crowns is carried out taking into account the thickness of the walls of the structure. The walls of the prepared tooth should converge upward so that the crown can be easily put on the tooth. At the same time, ledges are made in the cervical area of \u200b\u200bthe tooth.
• Dental pulp if necessary. The specialist decides whether to place crowns on live or dead teeth.
• If top part the tooth is missing, then the doctor installs a stump metal tab. It will help to securely fix the crown on the tooth.
• If there is no anatomical crown of the tooth, a pin is placed in the root of the tooth.
• Taking casts, which are then sent by the doctor to the dental laboratory.
• Fitting the finished structure. Color selection.
• Fixation of the crown on the tooth with permanent or temporary cement (at the discretion of the doctor).

How does a dental crown differ from a filling

A dental crown and filling are used to restore the shape and appearance of the tooth.

Their difference:

• Tooth filling takes place directly in the patient's mouth. The filling is attached to the walls of the tooth. She acts as a wedge. When pressure is applied to the filling, it puts pressure on the walls of the tooth and can cause it to fracture. A large filling volume increases the likelihood of tooth fracture.
• A dental crown covers the tooth from above, so the tooth under the crown remains intact, even with strong pressure on it. The crown is made in the laboratory.

Video: "Restoration of the tooth crown with a filling"

The advantages of a dental crown:

• The material from which the crown is made is much stronger than that from which the fillings are made.
• The crown breaks less often. If the crown is uncemented or broken, then dental crown repair or replacement of the tooth crown is possible. This option is not possible with filling.
• The crown transmits the chewing pressure to the root. And the filling - on the remaining areas of the tooth, which can provoke a fracture.

For a high-quality tooth restoration, you must follow the following rule:

To restore a tooth with a filling, the defect should be no more than 1/3 of the volume of the remaining tooth. If the defect is 1/2 - 1/3, then the restoration is carried out with an insert or veneer. With the destruction of the dental crown by more than 50% - the most effective method restoration of a tooth - a crown.

Service life of dental crowns

The service life of dental crowns depends on factors: from the material from which the crown is made, the quality of the construction, the care of the prosthesis, the condition of the gums.

• Metal crowns have a service life of 25 years or more.
• Cermet crowns - 10-12 years.
• Metal-free structures have less use - from 5 to 10 years.

Often the crown has to be removed not because of wear, but because of problems with the tooth under the crown. Poor preparation of the tooth for prosthetics may be the reason.

A year and a half after prosthetics, when the warranty on dental crowns ends, chronic inflammation in the area of \u200b\u200bthe dental root often manifests itself, which is characterized by swelling and soreness of the gums, an unpleasant odor may appear from under the crown of the tooth.

The service life of crowns is influenced by oral care.

Care

• The same as for real teeth. It is advisable to visit the dentist at least once every six months to check the condition of the structure and surrounding tissues.
• If single crowns are installed in the mouth, then they can be cleaned with a toothbrush with paste and floss.
• If there is a bridge in the oral cavity, irrigators are recommended for irrigating the structure. Thus, food debris and soft plaque are removed from hard-to-reach places.

Frequently asked Questions

• Question: The doctor suggests placing crowns on the teeth. Is it bad for a tooth to grind?

Answer: Grinding is a traumatic procedure for a tooth. It is a necessary stage in the preparation of a tooth for a crown.

• Question: How much does a metal-ceramic crown cost?

Answer:The cost depends on how much and what kind of metal will be used. Depending on this, such a crown will cost from 3 to 40 thousand rubles.

Answer: A ceramic crown looks no different from a real tooth. It is better to put a metal-ceramic or metal crown on the chewing teeth, because they are more durable.

• Question: How are dental crowns glued to the tooth?

Answer: To glue the crowns, use dental cement or special glue for dental crowns.

• Question: Do teeth deteriorate under the crown?

Answer: If the preparation for the installation of the crown is carried out with high quality, then the teeth under the crown cannot deteriorate. After all, the crown is put on the tooth in order to preserve it.

• Question: How to clean dental crowns?

Answer: Crowns should be cleaned in the same way as all other teeth with a toothbrush with toothpaste and floss.

• Question: Can there be any complications after installing a crown on the teeth?

Answer: If a high-quality preparation of the tooth was carried out before installing the crown, then there should be no complications.

Prices for dental crowns

The cost of a crown per tooth depends on the material and method of its manufacture.

More expensive ceramic crowns are usually recommended for use only on the front teeth, therefore, in order to save money, cheaper crowns, for example, from metal ceramics, can be placed on the chewing teeth.

Video: “Metal-ceramic crowns. Some features "

The technology of installing a crown on a tooth - stages, price. Sometimes the only way to protect a decaying tooth or improve its appearance is with a crown. There are many materials, the choice of which is carried out depending on the location of the organ, the degree of its damage, the patient's ability to pay. The sequence of actions during the installation of the crown is equally important, as well as the qualifications of the dentist. Errors and inaccuracies can lead to the impossibility of wearing the structure.

What is a crown

This is a type of dental restoration that covers the outer part of the organs and is fixed with special cement.

There may be several reasons for using it:

• The need to return the anatomical shape of the tooth;
• The organ loses its function;
• Unaesthetic appearance of the tooth, violation of its position in the row.

Unlike a filling, the crown becomes the new surface of the organ, covering it from all sides. This helps to strengthen the tooth in the mouth. They create constructions outside of it, in the laboratory, taking into account the peculiarities of the bite. The thickness of the crowns, depending on the material, ranges from 0.2 to 1.7 mm.

How the crown is installed

It is useful for the patient to know this in detail, so as not to worry about what is happening and to correctly assess the doctor's professionalism or lack thereof.

The installation steps take place in the following sequence:

Features of installing a crown on an implant

This is a longer procedure for which atrophy can be an obstacle bone tissue... Therefore, the installation is complemented by the following steps:

1. Bone augmentation before or during implantation. This will align the dentition. Into the fabric an artificial or natural substitute is introduced, which provokes the formation of new bone mass;
2. Implantation, that is, the installation of an artificial root. It is carried out with cutting the gums or puncture... The first method is more traumatic with stitching and long recovery. The second compares favorably with a full-fledged operation fast healing... But the doctor chooses the technique based on the condition of the bone, the type of implant. Its engraftment lasts 3-6 monthsthat can be worn with a removable crown.

The following steps are the same as when installing other types of structures.

Types of crowns and their cost

There are several materials for the manufacture of crowns, sometimes a combination of them is used.

The price of the structure depends on the cost of the composition used, as well as the effectiveness of the restoration:

• PFM crowns consist of cobalt-chrome or cobalt-

  

  a nickel base and a ceramic outer layer. Sometimes for the base they use gold, palladium or platinum... Price from 8000 rubles for a Russian or Belarusian crown to 12000 for an imported one. Precious metals increase the cost up to 30,000 rubles;

• Ceramic crowns are only intended to be used

  

  material. They are of 2 types: porcelain and zirconia... The first ones are used for the restoration of anterior teeth due to their extreme aesthetics and fragility. The latter have an internal base part of zirconium dioxide and a ceramic outer, which makes them both durable and beautiful. A porcelain crown costs from 20,000 rubles, a zirconium crown - from 26,000;

• Metal crowns are cast from cobalt-chrome alloy or gold.

  

  This is a fairly reliable and durable construction that does not differ in resemblance to natural teeth. Its price is calculated from 7,000 rubles. The high cost of metal is added to the cost of a gold crown, which in total gives an amount of 20,000 rubles. Stamped metal crowns, that is, those made from blanks, are of low quality and are almost never used. Their price is from 3,500 rubles;

• Metal-composite crowns consist of cobalt-chromium alloy inside,

  

  covered with plastic on top. They are characterized by the fact that over time they lose their attractive appearance, strength, accumulate moisture and microorganisms. The monomer in the outer layer is a strong allergen. The cost of metal-composite crowns - from 7,000 rubles;

• Implant crowns allow you to restore severely damaged teeth

  

  or replace the missing ones. For installation in the bone, implant titanium rod, on which after a while or immediately the upper part of the structure is attached. It is made by their cermet or zirconium oxide. The cost is from 20,000 rubles.
