Metal dental crowns. When are metal coated crowns used? Advantages over stamped and metal-ceramic crowns

Dental prosthetics using metal crowns is one of the old and time-tested methods of restoring teeth. DentaBravo dental clinic uses modern technologies for manufacturing metal crowns.

What are metal crowns?

These are fixed prostheses made from alloys of various metals. Metal crowns are highly durable and durable. Such a prosthesis perfectly withstands chewing loads, however, in terms of aesthetics, it is inferior to crowns made of ceramics and metal-ceramics.

What types of metal crowns are there?

There are several types of metal crowns: stamped and cast.

The stamping method, in which the crown is made from a steel sleeve, is now considered obsolete. In modern dental laboratories, solid casting technology is used, when the crown is cast according to the model of the patient’s tooth.

What alloys are metal crowns made from?

A solid metal crown can be made from cobalt-chromium alloy, titanium, gold alloys, as well as from cobalt-chromium alloy with electroplated gold. The choice of material depends on the specific clinical situation and the wishes of the patient.

What are the advantages of solid metal crowns?

Cast all-metal crowns are characterized by unsurpassed strength. They do not break, do not wear out or chip. The natural anatomical shape of such crowns allows them to fit as tightly as possible to the tooth stump. In addition, they are biologically inert, which makes such prostheses acceptable for almost all patients.

What are the disadvantages of metal crowns?

Perhaps the only drawback of metal crowns is their appearance. Since they are not white, this option is best not used for teeth that are visible when you smile. However, such a prosthesis is suitable for molars located at the end of the dentition.

What are the quality criteria for metal crowns?

A high-quality crown fits well to the tooth stump in the cervical area, its shape exactly repeats the anatomical shape of the tooth for which it is made. The metal crown should not have visual defects in the form of pores, cracks, sagging and perforations. She has close contact with antagonist teeth and adjacent teeth.

What metal crowns are of the highest quality?

These are crowns made from precious metal alloys. Such crowns will not cause premature wear of opposing teeth. They are hypoallergenic. In addition, such alloys are easy to work with: the physical properties of these metals make it possible to easily give products any shape. This quality helps the dentist achieve the most accurate fit of the crown on the tooth.

What is the cost of metal crowns?

The price of crowns depends on the material from which they are made and some other nuances. Approximate prices can be seen on this page. However, to find out exactly how much metal dentures will cost you, make an appointment with your dentist.

Bridges and metal crowns have low aesthetic values. Therefore, they are coated with a white dense substance to improve their appearance. Coated metal crowns have good aesthetic characteristics, so they are successfully used not only on the chewing group, but also on the front.

The first plating dental crowns were made to look like gold. Such products did not look very attractive. Steel devices were also used; they were more durable and did not negatively affect the oral cavity. Metal structures are used for restoration of the chewing group, since they are able to withstand increased loads during chewing.

The main indications for prosthetics using metals include:

  • protection against caries and tooth decay in the future;
  • destruction of the unit with root canal filling;
  • prosthetics on pins;
  • restoration of the chewing group;
  • Bridge device support.

Solid structures are made from pre-made individual impressions, so they are not only firmly fixed to the tooth, but also serve for a long period of time.

Classification of solid devices

In dental practice, the following models are used to restore dentition:

Characteristics

What is spraying a crown on a tooth? The metal device is coated on top with a special white substance – titanium nitride using vacuum plasma technology. Metal crowns are sprayed onto a tooth at high temperatures under a nitrogen atmosphere and using an electric current. To ensure a strong connection between metals, the product is first degreased and polished.

The device is coated on all sides; crowns cannot be partially sprayed onto the tooth using a white substance. But when making a bridge or crown with plastic particles, this is taken into account when creating the coating. According to many experts, the coating negatively affects the oral cavity and the body.

When to use

The coating is used not only in prosthetics, but also in dental treatment. If the enamel is severely damaged, a special paint is applied to the teeth, which protects the enamel from further destruction and provides excellent aesthetic results.

During prosthetics, metal structures are covered on top with a white substance. This allows them to be used for the front group. Designs with zirconium coating are also used. In this case, the material is a zirconium mass, which is evenly distributed onto a metal base. This material acts as a barrier to the penetration of metal particles into the oral cavity, thereby minimizing the risk of an allergic reaction to metal.

Types of alloys

The following alloys are used to create the coating: gold-containing, titanium, chromium-cobalt, silver-palladium, steel. The disadvantage of many products is the lack of naturalness, since in accordance with the color of the base metal, the products acquire a silver, gold or steel tint. The most attractive are devices with gold cladding. They have a smooth surface and do not accumulate pathogens and food particles. Gold is considered an antiseptic material.

The disadvantage of such designs is that they are too expensive and are not available to all patients. Currently, titanium nitride coatings are increasingly used in dental practice. It looks as natural as possible; such models can be placed not only on the chewing group of the dentition, but also on the frontal group, since they have high aesthetic indicators.

The advantages of devices with cladding include:

  • long period of operation;
  • maximum naturalness, their shade does not differ from real elements;
  • imitation of the anatomical shape of a real element;
  • no allergic reactions to metal;
  • tight grip around the neck of the tooth, so that the patient does not feel a foreign object in the mouth.

An undeniable advantage of such dental devices is also the fact that during their use the taste sensations do not deteriorate, since there is no metallic taste in the mouth, which cannot be said about traditional designs made of dental steel. The doctor decides which device to choose for dental restoration based on the condition of the oral cavity and his own tooth. An important factor in choosing models is the patient’s budget, since crowns with different coatings differ significantly in cost and are not available to every person.

Teeth are normal Dental prosthetics Metal crowns with spraying and their advantages

Probably everyone remembers the times when a “golden” smile was considered a prestigious and spectacular accessory, beneficially complementing the appearance of every second resident of our country. Nowadays, metal crowns with coating are no longer as incredibly popular as they once were, but nevertheless they firmly hold their position among more modern methods of tooth restoration.

Advantages and disadvantages of coated metal dental crowns

Expert opinion. Dentist Ivnitsky A.L.: “Until now, people of the older generation have confidence in metal alloys, giving them preference when it comes to dental prosthetics. Dental structures made of metals have truly earned trust due to their high level of wear resistance and biocompatibility, thanks to which their owners forgot about dental problems for many years.”

“Iron teeth,” as they were once called, have all the properties of the metal from which they are made. There are several types of alloys that are used in dentistry:

  • gold-containing;
  • titanium;
  • chromium-cobalt;
  • silver-palladium;
  • steel.

Their common disadvantage is the lack of naturalness - in accordance with the color of the base metal, they have a silver, gold or steel tint. They have the most neat and attractive appearance: the properties of this metal make it possible to produce durable crowns with a perfectly smooth surface that does not accumulate bacteria and is a natural antiseptic in the oral cavity.

However, ordering artificial teeth made entirely of gold is an expensive pleasure that not everyone can afford. In this case, it is advisable to install a structure made of a cheaper alloy - the cost of a metal crown coated with precious metals is several times lower. In addition, they have several significant advantages:

Metal crowns are highly durable and reliable.

  • have durability;
  • well imitate the anatomical shape of natural teeth;
  • less allergenic than non-coated crowns;
  • look more beautiful and presentable;
  • fit tightly and do not create the unpleasant sensation of having a foreign object in the mouth.

An undoubted advantage of such dental structures is that they do not spoil the taste of the products - the taste from spraying on a metal crown is completely absent, which cannot be said about products made from simple dental steel.

What teeth are coated crowns placed on?

The scope of application of coated metal depends solely on the wishes and tastes of patients and has practically no boundaries. At the same time, there are some established stereotypes that allow you to navigate what metal orthopedic products are suitable for.

A one-piece crown for chewing teeth is an ideal option.

  • Front teeth. To restore them, you can use any type of structure, but for aesthetic reasons, dentists advise patients to opt for a metal crown coated with white zirconium. This is a type of material used in the production of metal-ceramic structures, but it differs favorably from them in its longer service life.
  • Chewing teeth. For their restoration, it is better not to use crowns with porcelain (ceramic) coating: they are too fragile for this level of load. But solid crowns, on the contrary, perfectly withstand chewing even the coarsest food and do not lose their functional qualities for a long time.

Considering the availability and high quality of metal crowns, they will be in demand for a long time, and perhaps someday the fashion for a gold-toothed smile will return again.

Spraying enamel on teeth is a full-fledged independent segment in the aesthetic dentistry industry. The method is widely used in dental prosthetics, as well as in restoring the visual attractiveness of a smile after aggressive treatment. Spraying refers to the uniform application of a special specific paint to the surface of the teeth, after which it firmly “sticks” to them and creates the effect of a natural snow-white smile.

For whom is the procedure relevant?

I must say, the procedure is not so popular in itself. A person with a completely healthy oral cavity resorts to completely different methods of whitening, ranging from laser to medication.

But if the enamel is destroyed on its own, or a person needs unattractive dentures, spraying creates the greatest demand among dental patients. Some prefer even exotic techniques of spraying enamel on their teeth to make them platinum or gold. But first things first.

  1. The process of destruction of enamel leads not only to numerous diseases of the oral cavity, but also to a significant decrease in the aesthetics of a smile. And alas, banal teeth cleaning cannot cope with this destructive process, even if it is performed by a professional on an outpatient basis.
  2. However, there is a new hygienic procedure that involves not only effective sanitation of the oral cavity, but also medicinal spraying of concentrated calcium onto the surface of the teeth. Previous cleaning techniques, for example, ultrasonic, were aimed only at eliminating the stone and subsequent application of fluoride-containing paste to the surface of the bone tissue.
  3. This method really helped to avoid the formation of carious cavities, but it only protected dentin, without affecting the deep structures.
  4. Modern cleaning technologies are suitable not only for whitening, but also for deep restoration of tooth enamel. During the procedure, the dentist applies a special solution containing calcium in the optimal amount.
  5. In luxury segment blades, exclusive products are used for this procedure, for example, pearl powder. As a result, the tooth is saturated with calcium and becomes much less susceptible to various diseases.
  6. In addition, the surface is polished, which creates the effect of a real Hollywood smile. The powder granules have a specific structure and do not contain hard abrasives, which eliminates an increase in sensitivity after using the method.

As a result of cleaning with calcined coating, the patient receives:

  • A charming snow-white smile;
  • Healthy shine and ideal density;
  • Minimum sensitivity threshold after applying the method;
  • Strengthening teeth and prolonging their healthy state;
  • Reliable protection against caries, pulpitis and other destructive processes.

How is the procedure performed?

It must be said that not every average patient can afford such a procedure. It, like standard professional cleaning, is recommended to be performed regularly, at a certain time interval.

However, it is she who provides high-quality oral care, so fans of Hollywood smiles should still spend money on it.

Each clinic uses different formulations when spraying teeth to make them whiter. If you decide to resort to such a procedure, specify which particular remedy will be used in your case.

  1. The composition itself is applied sequentially, mainly using a laser. This procedure is completely painless and safe, and therefore arouses genuine interest among numerous clients of aesthetic dental offices.
  2. Sprayed crowns are standardly used for dental prosthetics. However, standard implants may not be suitable for everyone, because the color of the “native” enamel is as unique as everything in the human form.
  3. Agree, a snow-white crown will contrast with nearby teeth of a grayish or yellowish tint. It is for this reason that spraying is used simultaneously on all teeth, at least those that are exposed when smiling.
  4. Spraying tooth enamel with zirconium is now extremely popular. The fact is that zirconium dioxide crowns themselves are quite expensive.
  5. However, with a limited budget, it is possible to use the same material on already installed metal crowns. Crowns on teeth coated with high-quality zirconium are absolutely no different from the “healthy” part of the mouth.
  6. In addition to the aesthetic part, this method ensures the creation of a dense zirconium layer on the pins themselves, thereby helping to protect against metal penetration into the oral cavity. But the installation of metal prostheses often leads to rejection of foreign bodies and the development of allergic reactions.

Prosthetics with one-step spraying

If it happens that you have lost your teeth and you need to restore them without compromising your beauty, the best option for you is dental prosthetics with spraying. Metal crowns and bridges do not look very attractive, and this is no secret. And if you cover them with a dense substance that imitates healthy, polished enamel, the appearance will not only be restored, but also significantly transformed.

Remember the first prosthetics that we all saw in the 90s? They were gold teeth, i.e. crowns with gold plating. This is not to say that this method was cheap, but it was used by everyone who had lost teeth.

  • Despite the real gold sparkling in the mouth, this method was not visually acceptable. Although, to be honest, some outrageous people deliberately resort to it today, when dentistry, in particular aesthetic dentistry, has been developed, it would seem, to its evolutionary limit.
  • There were also steel prostheses. They were cheaper, but much stronger. In addition, they caused almost no allergic reactions or problems with gum inflammation.
  • Modern metal simulators of teeth with coating are in no way different from their healthy and intact “neighbors”. Prosthetics takes place in several stages: a pin is created, then an impression is made, and only after that a special composition is applied to the frame, creating the effect of a full-fledged tooth.
  • Titanium nitride is often applied to coated iron dental prostheses. This procedure is carried out using the vacuum-plasma method. As a result, the tooth looks as if it was molded from gold. Some patients contact clinics with a request to cover only part of the tooth with gold. This is impossible, since the entire prosthesis is sprayed on both sides.
  • Spraying enamel can be useful to you in several situations. If prosthetics has taken place, this procedure will become most relevant. You can also safely resort to it to strengthen natural enamel or safely whiten teeth. Whatever your whim or need, we strongly recommend that you contact an experienced and competent specialist.

Due to the high demand for dental services, many private clinics and dental offices have appeared, employing newcomers and trainees.

Beautiful teeth are a person’s calling card. It has been proven that people who are not ashamed of their smile have straight and healthy teeth are much more successful in both professional and personal life. Not every person can boast that Mother Nature gave him a perfect smile.

That is why it is important to resort to the services of modern dentistry in a timely manner. By installing a one-piece crown, you ensure yourself healthy and beautiful teeth. Metal standard dentures are a good way to significantly improve self-esteem.

Features of a one-piece crown in dentistry

The popularity of solid metal crowns is well founded. The production of such metal crowns is carried out strictly according to individual orders and from a specific alloy. A dentist will help you choose a crown. In addition, it is recommended to visit an allergist to check your body’s reaction to the installation of such a crown.

A cast crown is placed when the back teeth, called molars, are damaged. Under special circumstances, a solid crown is also placed on the front row of teeth. If your tooth is crumbling, decaying and losing support, these crowns are perfect. An all-metal crown can be installed as a support that will hold bridge structures. The most common types are:

Gold is a very plastic metal, reminiscent of tooth enamel in its properties. Gold wears out at the same rate, but the strength of the cast tooth is not affected. That is why this material is most often used when making a metal crown.

Nickel and chromium are cheaper materials that need to be protected from external damage. It is believed that such a product can last from five to seven years with proper care from the patient. You can see such a metal crown in photos and videos quite often: this procedure is common in dental practice.


Indications and contraindications for installation

Like any medical dental procedure, the installation of a solid crown requires justification. Making any product takes time. It is not possible to install a one-piece crown only at the request of the patient, since such a procedure can disrupt the natural processes in the oral cavity.

The main indications for securing a cast crown include:

  • massive and irreparable destruction of part of the tooth;
  • anomalies in the location of teeth;
  • irregular teeth shape;
  • supports are required to support bridge structures;
  • pathological thinning and destruction of fragile tooth enamel;
  • malocclusion;
  • genetic abnormalities that cause an unnaturally small crown size;
  • pathological grinding of teeth during sleep, due to which the enamel wears off;
  • dysfunction of the jaw chewing muscles.

Unfortunately, a solid crown is not suitable for everyone. Be sure to consult your dentist before installing one for yourself.

An incorrectly selected method of dental surgery can cause unpleasant consequences. Important contraindications to installing a cast crown:

  • childhood and early adolescence;
  • pregnancy in all trimesters;
  • breastfeeding period;
  • the presence of acute allergic reactions to alloy components;
  • massive traumatic damage to the dentition.

Varieties

Currently, there are three main types of crowns: solid, metal-ceramic and stamped. The price of a stamped crown is much lower because it is easier to manufacture. Ceramic metal looks very natural and is highly durable.

Types of casting products:

  1. No spraying. This is a cheap and simple option for a metal crown.
  2. Sprayed. Its disadvantage is the possibility of an allergic reaction, as well as low fixation of metal-free bridges.
  3. With cladding. This option looks very nice on the front teeth, but lasts even less time than the stamped steel variation.

Advantages over stamped and metal-ceramic crowns

A stamped crown is not superior to a solid cast one. This is a long-gone procedure that is not performed in all clinics in the country. The appearance of a stamped crown is a small cap that covers the top of the treated tooth. The stages of making a stamped crown can be clarified with your doctor.

Significant advantages of cast construction:

  • smooth and even surface;
  • longer service life compared to a stamped crown;
  • stamped crowns cannot fit tightly to the tooth, unlike other designs;
  • lower risk of infection.

Important advantages of a one-piece crown that compensate for the disadvantages of other methods:

Construction manufacturing process

All metal, stamped and metal structures are considered to be easier to manufacture than cast products. However, metal teeth have much less aesthetics. To make an original, individual and easy-to-wear design, you need to perform the following sequence of actions:

  1. taking an impression of the tooth on which installation is planned;
  2. making a special plaster model exactly suitable for correcting the bite;
  3. formation of a wax composition;
  4. replacing wax with metal;
  5. grinding and polishing work.

Stages of installing a crown on teeth

The installation process in which a person receives their dentures is lengthy and can take anywhere from several days to several weeks. Metal-composite and metal-free structures are installed a little faster than solid cast ones. Gold ones take a little longer to make; soldering takes a lot of time. Main stages of the procedure:

Caring for a solid crown

To keep your dentures sparkling white not only after installation, but also for a long time, you need to take extra care of your oral cavity throughout your life. Iron dentures are more susceptible to bacteria, which is why you should not neglect twice-daily cleaning. It will also be useful to use a special balm.

People who smoke will have to give up their bad habit: the health and cleanliness of the oral cavity is at stake. You should limit the consumption of coloring drinks and foods: they can affect the result of the procedure and change the color of the product. If you are not ready to take such serious measures, it is recommended to postpone the procedure for several months.

When the installation is successful, you need to visit the dentist every six months for professional teeth cleaning. Gold teeth and bridge structures require mandatory care from a specialist.

Dentures will serve you faithfully for many years of your life if you follow your dentist’s instructions and do not ignore your morning and evening hygiene procedures.

Price

A solid crown, made of simple chrome or nickel, without coating, will cost you about two or three thousand rubles. Metal crowns with coating cost about five thousand rubles. If you want to install exclusive gold or platinum alloys, the price it will cost to produce such a solid crown will increase significantly.

If you want to change your smile and restore lost dental function, do not rush and contact the first clinic you come across. Pay special attention to choosing a competent specialist with extensive experience in this field. Explore possible options, take into account the recommendations of friends and go to consultations. By acting in this way, you can protect yourself from poorly done work, and your new teeth will last you much longer.
