Coated metal crowns price. White coating on metal crowns Metal crowns on teeth with white coating

Metals have been used in prosthetics since the last century and do not lose their relevance today. Dental crowns are made with various materials sprayed "for every taste" to give an aesthetic appearance from gold, platinum, silver, steel. A fundamental factor in the long-term use of metals in dentistry is durability, proven by the century, although the presence of gold teeth was considered a kind of charm of the 20th century, elevating the owner to the rank of self-sufficiency and invulnerability.

Metal alloys as elements of prosthetics have earned high confidence due to wear resistance, biological compatibility and forgetting about the extremely unpleasant procedure of the last century - visiting the dentist's office for many years. A breakthrough in dentistry of that period was the process of coating crowns borrowed from industry with a special material at a high temperature in a nitrogen atmosphere, called sputtering.

Coated metal dental crowns have two manufacturing methods:

• stamping - from standard blanks based on stainless material;
• - with the processing of a tooth with a ledge, taking an impression, casting, wax modeling, subsequent remelting of the wax blank into metal and the application of spraying material.

The stamping crown is practically not used, because it does not fit snugly against the tooth, allowing food to get under the structure, which leads to caries and tooth loss. An addition to the shortcomings is an unaesthetic appearance.

Important! A cast crown or prosthesis is made using a technology similar to the production of crowns from expensive materials: and. A positive distinguishing point is the turning of the smaller surface of the tooth enamel and dentin, which allows not to remove the dental nerve. The design is actively used in dental prosthetics.

Advantages and disadvantages

Cast metal crowns, coated with precious metals, porcelain and plastic, have a number of advantages:

• long period of use;
• presentable appearance;
• high imitation of the anatomical shape of lost teeth;
• lack of sensation foreign body in the mouth;
• strength is several times higher than that of non-metallic structures;
• the minimum surface used for turning, which makes it possible not to depulp the teeth;
• full restoration of the functional properties of the jaws;
• ideal support for a bridge prosthesis;
• ease of manufacture, affordability.

The disadvantages include the loss in external parameters of cermet and.

Crowns have advantages and disadvantages depending on the working material of the manufactured structure and the selected coating. Comparative characteristics are presented in the table:

Type of crown	Advantages	Flaws
Steel coated with base metal.	Low cost, ease of manufacture and installation, unpretentious maintenance.	High risk of galvanic and allergic reaction due to incompatibility of different metals.
Steel coated with precious metal.	No galvanic effect and metallic taste in the mouth.	Relatively high cost without aesthetic justification.
Steel coated with plastic.	Presentable appearance without investing money.	High chance of chipping as metal and plastic don't mix well.
Steel coated with porcelain.	Maximum aesthetics for a long time at the lowest price.	Porcelain spraying and cermets differ in nature, therefore there is a possibility of chipping.
Golden.	The similarity in erasing with tooth enamel ensures durability, the metal is an excellent antiseptic and anti-allergen.	The ratio between price and aesthetics leaves much to be desired.

Important! Do not confuse the concepts of metal spraying with porcelain and ceramic-metal, filling metal with plastic and metal-plastic crowns.

Allergic reaction

An allergic reaction can be caused by individual intolerance to a particular type of metal or metal coating. According to statistics, the percentage is about 5-10 of total strength using crowns.

In 90% -95% of cases, allergies are provoked by the incompatibility of several types of base metals that are simultaneously in the mouth. A steel crown coated with base metals falls into the highest risk group for allergenicity compared to analogues.

Dmitry Sidorov

Dentist-orthopedist

Important! The likelihood of allergies is high in the presence of several base metals in the oral cavity. Therefore, when choosing a material for a patient, the doctor should take into account the possible complex reaction of base metals.

Porcelain and plastic are considered absolutely hypoallergenic, precious metals (if present in the composition of more than 60%) can have an anti-allergic effect, beneficially affecting the organs and systems of the body.

Operation period

Punch crowns of the past did not have a long service life, regardless of the underlying material. The reasons were:

• lack of an individual cast for high-quality restoration of the crown part of missing teeth;
• imbalance between the antagonist teeth due to stamping and the lack of anatomical shape of the elements to be restored;
• loose fit of crowns, leading to caries, requiring repeated prosthetics, even in cases of installation of a prosthesis made of precious metals.

The service life of crowns and bridges on average did not exceed five years.

Cast dental crowns with the right coating can last forever. The service life is increased by precious metals due to the antiseptic effect in the oral cavity, the softness of the materials, the same parameters for erasing with tooth enamel.

Important! Metals are more reliable than non-metal prostheses in strength, which served as the foundation for installation in the chewing part of the jaw. The patient needs to choose a clinic to perform quality prosthetics to maximize life, otherwise the prostheses have to be re-fitted, which was confirmed in the stamping situation.

Conclusion

There is not always equality in the ratio of price and quality parameters. Confirmation - metal dental crowns and prostheses. With the growth of technological processes of prosthetics, the creation of special computer programs and the use of high-quality materials, metal crowns continue to be in demand in the dental services market. A properly selected and installed crown with a coating can last forever, naturally taking root in the mouth and providing the wearer with a state of constant comfort.

Metal crowns are orthopedic structures made of metal alloys that restore the anatomical shape and function of teeth. Treatment with metal crowns is quite old, but effective method. Such designs are very strong, durable and inexpensive.

Pros and cons

The advantages of metal crowns include:

1. Effective restoration of functions (chewing, swallowing, speech);
2. High strength;
3. Tight fit to the tissues of the tooth;
4. Absence of chips and breakages;
5. Anatomical shape of the structure;
6. No damage to opposing teeth;
7. Does not require complex tooth preparation and nerve removal;
8. Small cost;
9. Long service life.

The disadvantages of the design are:

• Poor aesthetics. Crowns look very different from natural teeth. When installing a metal crown on the front tooth, the design is very noticeable to others and will violate the aesthetics of the smile;
• If you are allergic to metals, do not install a metal crown. It is only possible to manufacture other types of structures or crowns of gold. Since there is practically no allergy to this metal;
• After a long period of time, the crown wears off;
• Perhaps the occurrence of galvanic currents in the oral cavity due to the presence of several types of metal in the mouth. Galvanic currents cause unpleasant symptoms: headache, metallic taste, eating disorders, burning in the mouth, poor sleep;
• With a long service life of the crown, the neck of the tooth may be exposed, food can get under the crown and a carious process may occur.

Kinds

Metal crowns are cast and stamped. Solid products are manufactured according to individual casts teeth by firing at high temperature in a special oven. Such crowns have thick cast walls, which makes the design very durable. Crowns are used on the lateral group of teeth due to their resistance to chewing pressure. Solid crowns are of the following types:

1. Sprayed. At the request of the patient, the crowns are covered with a golden coating and look like gold teeth;
2. Zirconium-coated is a new type of design in which metal crowns are coated with a small layer of zirconia. Spraying isolates the oral cavity from metal, can be used for allergies, does not cause galvanic currents. Zirconia crowns are the best, highest quality and most expensive. Spraying is an inexpensive crown option that will have some of the benefits of zirconia.
3. Without spraying - these are ordinary products that have a steel or silver color;
4. With a covering (facing). To make the designs more aesthetic, the front (front) surface is covered with ceramic mass. At the same time, the crown looks natural and does not catch the eye. The disadvantage of ceramic veneers is the risk of chipping, so it is recommended not to load the artificial tooth.

Stamped crowns are a metal cap. For manufacturing, standard sleeves are used and grinding is carried out with a special machine to give the desired shape of the tooth. Such crowns are easy to manufacture and have a low cost. When preparing the teeth, the minimum amount of hard tissue is removed, so there is no need to depulp the tooth.

The disadvantages of the design include: erasure after prolonged use, incomplete restoration of the anatomy of the tooth, the risk of caries at the border of the crown and enamel.

Preparation for a cast crown

An important stage in the manufacture of the structure is the preparation, that is, the preparation of the tooth. Preparation for a solid metal crown consists of grinding the interdental contacts, the chewing surface of the tooth or the cutting edge by 0.2 - 0.3 mm. Next, the vestibular and oral sides of the tooth are prepared with an unnecessary thickness, as a result of which the tooth acquires a cylindrical shape. Preparations are carried out using special burs and a drill.

The finished stump for the crown looks like a truncated cone, the walls converge at an angle of 2-8 degrees. Experienced doctors create a ledge in the neck of the tooth. The ledge improves the fixation of the future structure and is an additional retention point for the dental technician. After preparation, the tooth is smoothed and polished using dental heads.

Care

After installing metal crowns, you must carefully follow the rules of hygienic care. In the absence of brushing teeth and interdental spaces, food debris accumulates in the area of ​​​​the neck of the teeth, between the crown and gum. When microorganisms and carbohydrates enter the area of ​​transition of the crown to the tooth, conditions are created for the development of a carious process. In addition, the tooth can collapse under the orthopedic structure.

To maintain the health of teeth and oral cavity organs, it is necessary to brush your teeth twice a day: in the morning and in the evening. During cleaning, you need to pay enough attention to the crowns, carefully clean the plaque between the crown and the gum. To clean the interdental spaces, it is recommended to use dental floss (flos).

To do this, you need to take a thread 15-20 cm long, wind it around your index fingers and clean between each tooth. After eating, use mouthwash or rinse your mouth with water. In case of periodontal diseases, rinsing with antiseptic solutions should be carried out, treatment with anti-inflammatory drugs should be carried out.

After the installation of crowns, one should not forget about the need for preventive examinations at the dentist. It is recommended to visit a doctor every 6 months, to carry out professional dental hygiene, to check the condition of the crowns. When bad smell refixation (re-installation on new cement) can be carried out from under the structure or violation of the fit of the crown.

Life time

Metal crowns have a long service life. Durable material makes it possible to operate the structure for 15-20 years or more. Very often, patients walk with crowns for more than 25 years. But it is recommended to replace crowns every 10 years. After a long period of time, atrophy and drooping of the gums occur, the edge of the crown is exposed. As a result, the crown may decement or dental disease may occur. If periodontal disease occurs, the service life of the crowns will be reduced.

The service life of the construction will also depend on the professionalism of the doctor, the dental technician, the type of construction and the conditions of use. In order for the crown to last longer, you need to follow the rules of care, avoid excessive chewing load on the tooth, periodically visit the dentist for a preventive examination.

How much does a metal crown cost

Metal crowns are an inexpensive design in dentistry. The cost will depend on the prestige of the dental clinic, its location, the professionalism of the doctor and dental technician. And also from the type of metal, when making a crown from gold or platinum alloys, the price will be high. On average, the cost of a metal crown ranges from 1,000 to 18,000 rubles. If you need to make an inlay for a crown, the price will be slightly higher.

Is it possible to do CT and MRI with metal crowns

Computed tomography and magnetic resonance imaging are important research methods in medicine. 90% of people have metal constructions in the oral cavity: crowns, pins, braces, implants, plates. The MRI method is based on the registration of response electron pulses when the required area of ​​study is placed in a powerful electromagnetic field.

During the study, a three-dimensional image is obtained, which allows you to evaluate the function and blood flow of the organ. Metallic elements in the body cause image shifts and abnormal examination results. Modern technologies allow MRI and CT to be performed in almost all cases due to the minimal use of pure metal alloys in dentistry.

Also, modern MRI machines allow you to change the settings and get reliable examination results. We can conclude that everyone can conduct examinations, you just need to inform the doctor about the metal structures in the mouth.

Coated metal crowns are very popular in practical dentistry. The metal frame itself has been used for a long time, you can still meet people with "gold" and "silver" teeth. Now dentistry has resolutely abandoned ugly sparkling metals and patients are offered to put coated products that do not differ from the rest of the dentition.

Coated structures retained the main feature of such products - a metal frame. But the outer coating is now modern different. Modern technologies for the manufacture of prostheses make it possible to cover the surface with enamel, one to one repeating the color of the tooth. Therefore, tooth-colored metal products are one of the most popular methods of prosthetics today.

Products with a coating and a metal frame have excellent endurance characteristics, they are able to withstand a large load in the process of chewing food, therefore, they are placed taking into account which teeth need to be prosthetized. Indications for the installation of metal structures:

• the need to protect the walls with severe destruction of the enamel walls;
• prosthetics on implants;
• the need to support bridge-like prosthetic structures;
• prosthetics of chewing teeth.

Frames are made to order. These are solid constructions, they sit perfectly on the tooth and tightly wrap around it. They provide excellent service over time, they are not easily damaged, and the surface of the structure does not leave chips, cracks in the enamel and grooves from chewing food.

A distinctive feature of modern dentures is a unique coating that makes them identical to your own teeth. Titanium nitride is used for spraying, and the procedure itself is carried out using the vacuum-plasma method.

The process of etching titanium nitride onto a metal base is carried out in a vacuum under the influence of high temperature and a certain voltage. The prosthetic part is degreased, polished, after which, under the influence of current from one electrode, the smallest particles pass to the frame, which performs the function of the second electrode.

Artificial enamel covers the entire surface of the frame. Patients may not worry that somewhere the product will not be completely processed and the metal may shine through - this is excluded. The only rendered metal part- this is the edge of the product, where titanium nitride is not applied, but when the structure is installed, it goes under the gum and remains invisible to others.

Product varieties

Coated metal crowns differ in the type of metal from which the framework is made, as well as in the method of manufacture. Regarding the method, it can be mentioned that the crowns are solid and stamped. Stamped ones are inferior to solid ones in terms of strength, and they are cheaper. But cast frames last much longer, so most patients choose these structures.

As for the metal from which the bases are made, they can be: steel, gold alloys, titanium alloys, cobalt and chromium alloy, silver and palladium.

Regardless of what the frame will be, the product after processing looks great and fully fits the dentition. To select the color of artificial enamel, the dentist checks the patient's enamel shade map and only then the metal is treated with titanium nitride.

Advantages of a spray frame

When choosing crowns, people are guided by various considerations - appearance, price of the product, etc. As for metal coated crowns, we can mention their advantages in order to focus the attention of patients when choosing this particular product:

• very durable and with proper installation, such structures will last more than a dozen years;
• are made according to an individual cast, and therefore most accurately imitate the shape of their own and fit perfectly into the dentition;
• hypoallergenic, therefore take root in most patients;
• in appearance, the novelties surpassed their predecessors in many respects, while maintaining the aesthetics of the patient's smile;
• in the oral cavity, the products fit perfectly into place, they fit snugly and do not create the feeling of a foreign object in the mouth.

An important advantage is the fact that the product does not give a metallic taste in the mouth, which was noted during prosthetics by predecessors - conventional metal frames.

Metal structures are mainly placed to perform complex tasks of chewing food, but products with titanium nitride can also be placed in the smile zone, where they are not so actively involved. Consider locations where such frames can be installed:

• frontal zone- doctors recommend installing durable crowns with a metal frame and zirconium coating. These crowns not only fit your own teeth, but are also particularly durable;
• chewing teeth- here it is better to use cast frames, as they are more durable. Moreover, in this zone, the presence of spraying does not play such an important role, because the chewing surfaces themselves are hidden from the eyes of others.

The choice of design varies according to different indicators and the optimal cost can be discussed with the doctor.

Not so long, but requiring preparation. The stages of prosthetics can be described as follows:

• at the first visit, the doctor conducts an examination and, if necessary, treats teeth from caries, pulpitis, etc.;
• with severe destruction of the walls, it may be necessary to install a pin or;
• after that, the surface is ground and an impression is made to make a crown;

• several times the frame is tried on, sent for revision - this is a completely normal process, rarely when it fits perfectly the first time;
• after the final fitting, the crown is sent to the laboratory for processing and the prosthetics will be successfully completed on the next visit.

It is worth noting that in the process of treating teeth and fitting the frame, the doctor continues to work with the patient's oral cavity - he does, removes the stone, etc. The patient is given recommendations on how to behave with a crown - do not gnaw nuts, seeds, candies and other hard foods. At the end of the treatment, the patient receives a crown with a coating and healthy teeth for many years to come.

Metal crowns are timeless classics, and they are in demand even though ceramic crowns have appeared, which look more attractive. What are their advantages?

Crowns are the best help for the most seemingly hopeless teeth. Even if the natural crown part is practically destroyed, there is no need to remove a healthy root. Of course, a titanium pin can be inserted in its place, but unnecessary interventions in the body are useless.

Metal crowns are considered by some to be a kind of "relic of the past" - they were replaced by snow-white ceramics. However, the quality of the "classics" is not called into question, and it is better to replace some with "iron". In addition, there is a great alternative - metal crowns with an even white coating.

What are they needed for

With the help of metal nozzles, you can restore teeth that have lost a large amount of hard tissue. The reason for the destruction does not matter, the main thing is a healthy root that can still be saved. V rare cases with the help of metal crowns on the teeth, they solve the problems of abnormal location or diastema.

Similar products are also needed to create a prosthesis, they are installed on a pin - an artificial root. With their help, you can completely restore the natural functionality, crowns cope with chewing loads no worse than real teeth.

Before installation, it is necessary to completely cure the problem tooth - remove caries, periodontitis or pulpitis, seal one root canals. Products take root better on non-depulped multi-rooted chewing teeth, therefore, during preparation, dentists try to preserve the pulp.

With a strong destruction of the coronal part, treatment alone is not enough - iron pins must be inserted into the root canals, part of the hard tissues can be restored using a composite (filling) material. After that, you can start turning the tooth for the installation of crowns.

Advantages and disadvantages

One of the main advantages is durability. Approximately iron chewing teeth can serve for several decades. It is almost impossible to damage them during operation, the risk of chips or cracks is reduced to zero. Crowns made of gold metals are very easy to process, they fit with maximum precision during installation and ideally imitate the required shape of the tooth. Another plus is that during chewing activity they do not have a negative effect on the opposite natural tooth.

Titanium crowns are not inferior in quality to gold prostheses - they do not have side effects, are non-toxic and are used even for the treatment of children's teeth. The quality and reliability of materials make it possible to place products on chewing teeth, which, unlike the front teeth, face serious chewing loads every day.

The most expensive option is gold dentures, the price of conventional metal dentures is less painful for the wallet.

The main disadvantage is the appearance: dental crowns made of metal look very different from natural ones, which is why they are practically not placed on the front teeth so as not to disturb the aesthetics of a smile. Their visibility will depend on the structure of the jaw, in some people chewing teeth are noticeable when talking. Coated metal crowns can solve the problem.

Products from a conventional alloy are affordable, but with individual intolerance to certain types of metals, they can cause an allergic reaction.

In this case, her crown will have to be removed and another option for prosthetics should be sought. Patients prone to allergies will have to choose more expensive, non- and safer metals that will not harm the body.

Stamped prostheses can be somewhat dangerous: there is a small gap between the tooth and the gum, because of this, there is a high probability of inflammation of the soft tissues, bad smell and development of caries. The thin walls of the “stamps” gradually wear out and can significantly worsen the condition of the tooth, which as a result will have to be removed.

Types of metal crowns

Metal dental crowns can be divided into two types: stamped and cast.

Forged products are easier to manufacture and their cost is lower than that of cast ones. The design is a cap that is put on the tooth like a case. With this method of prosthetics, minimal turning is required - the walls of stamped dental crowns are very thin, it is permissible to use on living teeth.

There are also disadvantages: the lost chewing functions are not fully restored, with long-term use, the material may be erased, and with a loose fit, there is a high risk of developing caries.

One-piece cast prostheses are made by the one-piece casting method. There are several options for the patient to choose from - with or without spraying, with lining or in the form of a combined bridge prosthesis. The advantages include strength and high wear resistance.

For the manufacture of cast crowns, it is necessary to first make an individual cast of the jaw, so that the shape of the product will be as similar as possible to natural teeth. This eliminates the risk of cracks, through which bacteria can penetrate under the crown.

In addition, such dentures can be made more aesthetic: by spraying on dental crowns. Another option is a plastic or ceramic veneer, which will make the tooth look as natural as possible. However, there is a small risk: the facing coating may crack, the appearance of small chips is not excluded.

Metal dental crowns

Metal crowns are made from a mixture of gold, copper, titanium and other metals that provide strength and corrosion resistance. One example of a classic metal crown is a gold crown, or more specifically, an alloy of gold. Over the decades, many different metal alloys have been used in the creation of dental crowns. Some of these metals may be silver in color and may contain various mixtures of various metals such as titanium, vitalium (a cobalt-chromium alloy), silver, etc. Next, we will consider in more detail the types of metal crowns.

Metal dental crowns

A gold crown is an excellent choice and is recommended for back teeth. Gold is a very workable metal - it helps to achieve a very precise fit to the crown. Gold crowns can withstand strong bites and squeezes well. Of all types of dental crowns, gold ones have the most potential for long-term wear. In addition, the wear rate of a gold crown is about the same as that of tooth enamel. This means that the gold on the dental crown will not create excessive wear on the opposing teeth. The only problem with gold crowns currently is the high cost of gold.

Metal crowns coated in white and yellow

In cases where a metal crown is being removed, you may have a preference as to whether the crown should be placed in yellow (like gold) or silver (“white”). The composition of the alloy determines its color. Noble metals for teeth: gold, platinum and palladium. In most cases, the total cost between using a noble or base metal alloy can be small, so if you have a large crown it can be the deciding factor.

Allergic harm and service life of metal crowns

You should also be aware that some people are allergic to metals. Studies have reported that about 10% of the female population and 5% of the male population are allergic to nickel, chromium and/or beryllium (these metals are often found in non-precious alloy crowns).

Solid metal crowns and bridges

As their name indicates, these prostheses consist entirely of a single piece of alloy. The metals used in crowns and bridges consist of gold alloys, other noble alloys (eg palladium) or a base metal alloy (eg nickel, chromium, titanium). Stainless steel or aluminum are used as temporary crowns.

Photo of metal crowns on teeth

Compared to other types of crowns, metal crowns minimize the removal of tooth structure and wear on opposing teeth. Metal crowns and metal bridges withstand strong bites, break less often and last longer. The main disadvantage of cast metal crowns during restoration is their unaesthetic appearance - metallic color is the main disadvantage. Indications

1. Metal crowns and bridges are a good choice for back teeth.
2. To replace acrylic or composite veneers, a cast metal crown may be the best choice.
3. Although porcelain fused to metal seems to be the best solution, solid crowns made of gold and titanium are still widely used on posterior teeth.

Solid gold crowns and bridges

Gold is an excellent alloy for teeth, used for various kinds indirect restorations such as:

• Crowns and bridges made of porcelain fused with gold.
• Solid gold crowns and bridges.
• Removable partial dentures or inserts.

Gold alloy is made up of many different types of elements: noble metals such as: gold, platinum, palladium, silver; Non-ferrous metals: copper, tin and others. The correct gold alloy should contain at least 60% precious metals.

Advantages of gold alloys 1. Gold alloy will not corrode. Some metal alloys, under the influence of saliva, can move to the so-called phenomenon as corrosion. This can result in an unsightly gray discoloration on the top of the tooth crown. 2. Gold alloy has superior strength and resistance. The main advantage is that gold alloys can be made to very thin thicknesses and still retain strength and stability. This has the advantage that less tooth tissue will be removed during the restoration. 3. Gold alloys are much lighter than non-ferrous alloys (with the exception of titanium). 4. Gold alloys are very well tolerated by the body and do not cause allergic reactions.

Cast metal titanium crowns and bridges

The use of titanium alloys for medical and dental work has risen sharply in recent years. Because of its many physical and mechanical properties, titanium is used as a material for dental implants and dentures. The strength and stiffness of titanium are comparable to other noble or high noble alloys used in dentistry.

In dentistry, titanium is used for many purposes: mainly for dental implants. It is the main material for the manufacture of porcelain crowns, solid metal crowns, etc. Although the cost of titanium prostheses is high, it usually does not reach the price of gold crowns.

Dental crowns made of base metal alloys

Solid metal prostheses are less expensive. They have good strength and durability, although they are inferior to gold or titanium alloys. Various metal alloys are used for manufacturing: nickel, chromium, iron and other stainless steels. As already mentioned, aluminum is used mainly for temporary crowns. It is a good choice when patients cannot afford more expensive crowns.

What are dental crowns

In modern dentistry, crowns for teeth are divided into types depending on the material from which they are made. They are metal, metal-ceramic and all-ceramic. When choosing one or another prosthesis, they proceed from clinical indications, the wishes of the patient himself and, of course, the cost.

Types of crowns for teeth

Metal. The first type of crowns that appeared, however, it still finds application. They are made from various metal alloys - titanium, stainless or chrome-cobalt steel. Metal dental crowns made of gold or platinum are also popular. They can be either completely made of precious metals, or only coated. Metal dental crowns provide a complete restoration of the chewing function of the tooth, but in appearance they are the most unaesthetic. The price of dental crowns made of metal is one of the most affordable.

Golden dental crowns. About 20 years ago, gold was the most popular crown material. Today, the “gold tooth” is more kitsch than fashion, but in the outback, gold dental crowns are sometimes still popular. As you know, gold, as well as a “medical” alloy based on it, are considered one of the most acceptable metals for the body, so it is advised, for example, to wear only gold earrings for the first six months after a piercing. However, what is beautiful in the ears is not very beautiful in the mouth. However, as mentioned above, such prostheses perform the chewing function quite adequately, which cannot be said about the aesthetic one.

Metal-ceramic dental crowns. The medium option, which combines strength and, judging by patient reviews of metal-ceramic dental crowns, a relatively natural appearance. The inner part of the structure is made of metal, and the outer part is made of ceramics. With all the advantages available, ceramic-metal prosthetics are inferior to all-ceramic ones, since even with a slight decrease in the gum, a metal rim becomes noticeable. But such a problem is eliminated if you install a crown with a ledge or use zirconium dioxide (white metal) instead of traditional alloys.

Ceramic. The most expensive and most aesthetic view. In addition to the fact that ceramics allow you to create constructions with the same transparency and color as natural teeth, it is also the most biocompatible material of all of the above. Ceramic crowns without metal impurities are ideal for prosthetics in the smile zone, but unfortunately, they are not always suitable for chewing teeth due to some strength problems.

Dental crowns on implants

When prosthetics on implants, the best option for restoring the front teeth, for which aesthetics is important, will be dental crowns made of metal-free ceramics. This is because the metal can show through the ceramic, which mimics the transparency of natural tooth tissue. Therefore, in order to achieve a high esthetic result, the use of a zirconia abutment is recommended. As for posterior teeth, aesthetics are not as important as functionality, so metal-ceramic dental crowns on implants may be acceptable. For those patients who do not compromise between aesthetics and function, zirconia crowns are recommended on the implant.

Installing a crown on a tooth

A dental crown is installed on one tooth in several stages.

Diagnostics. To find out if it is possible to put a crown on a tooth, the doctor examines the oral cavity visually and always sends it to an x-ray.

Treatment. Then carried out necessary treatment. Most likely, you will have to remove the nerve under the crown and fill the canals.

Grinding teeth for crowns. If dental tissue slightly destroyed, then the remaining walls are turned. In the case when the "top" of the tooth is completely absent, then an additional dental tab under the crown, which will ensure its reliable fixation. Previously, a pin was installed instead of an inlay; today, a dental crown on a pin is considered an outdated technique that has a number of complications leading to tooth loss.

Manufacturing of dental crowns. After carrying out all the preparatory manipulations, the patient is taken casts, which are sent to the dental laboratory.

Installation of dental crowns. This is followed by fitting the finished product in the oral cavity and installation. Many people are concerned about the question “How are dental crowns glued?”. Orthopedic constructions are planted on a special cement, which allows the prosthesis to hold on for a long time and reliably.

All manipulations are carried out over several visits. The production of dental crowns is possible in a few hours, provided that the necessary equipment is available in dentistry.

How to put a crown on a tooth

Crown on a living tooth without depulpation

If we are talking about grinding healthy teeth to fix a dental bridge, then an important question arises about the need for depulpation of the tooth. Everything is very individual here. But, as a rule, doctors prefer not to take risks and in most cases remove the nerve.

Color of dental crowns

Modern technologies make it possible to produce orthopedic structures that are indistinguishable from natural teeth. Naturally, we are talking about ceramic, metal-ceramic and plastic crowns, and not about metal ones. Ceramics, used in modern dentistry, is able to completely imitate the color and transparency of the enamel adjacent to the prosthetic teeth. The same applies to the plastic used to make temporary crowns. But if we are talking about metal ceramics, then crowns with a zirconium frame can “get into color”, and in the case of other metals, the frame can shine through artificial enamel. In modern dental laboratories, the color and shade of enamel for crowns is selected according to the Vita scale, which represents most of the natural shades of teeth.

How are dental crowns removed?

There are 3 main ways.

1. Kopp apparatus. With a special drill, the doctor breaks the cement at the base of the prosthesis, then removes the structure with forceps.
2. Sawing. The structure is cut in the center and removed.
3. Coronaflex. The crown is removed gently and without damage using compressed air. The method is expensive, but after the procedure it is possible to re-install an artificial tooth.

Dental crowns are removed when the following problems occur:

Toothache under the crown

Modern materials make it possible to make dental crowns that fit as closely as possible to the tissues of the prepared tooth, however, sadly, the patient sometimes gets the feeling that his dental crown hurts. Of course, it’s not the crown that hurts at all, but the tooth under it. Toothache under a crown can mean several different problems, but the most common is the formation of secondary caries at the site of the crown to the tooth tissues. If this happens, be prepared to remove dental crowns, re-prep teeth and install new orthopedic structures. If this is not done, the tooth under the crown can completely collapse, leading to its loss.

Caries under the crown

Sometimes this is due to a mistake by a doctor or a dental technician when the procedures for making or installing a crown were violated: if it does not fit snugly against the tooth, if saliva got under it during installation, if caries was not completely treated, the formation of secondary caries under the crown is more than likely .

Unpleasant smell from under the crown

The smell from under the dental crown occurs when food residues or saliva get under the prosthesis. Bacteria in this environment multiply faster, causing an unpleasant odor. Inflammatory processes in the dental tissues under the prosthesis also lead to an unpleasant odor.

Important! The removal of dental crowns and the installation of new ones must be done approximately every 10 years, otherwise you run the risk of being among those users who frantically write in the search bar in the browser: “I swallowed a dental crown, what should I do ?!”. By the way, modern materials for the manufacture of crowns are absolutely non-toxic; sharp edges and chips are dangerous if swallowed. Therefore, if it was not a small piece of a fallen off crown that was swallowed, but the entire structure or its solid part, you should consult a doctor - a surgeon, a gastroenterologist, or the nearest emergency room.

Can a crown on a tooth be inexpensive?

The cost of a dental crown for one tooth will directly depend on the type of material used, the method of its manufacture, the category of the clinic and its location, as well as the qualifications of the orthopedist. For example, in Moscow, prices for metal crowns can vary from 3,000 to 16,000 rubles, for ceramic-metal crowns - from 7,000 to 40,000 rubles, and the average cost ceramic crown is about 21,000 rubles. You can find out in more detail how much a particular dental crown for one tooth will cost at an in-person consultation at a dental clinic.

The best dental crowns

Perhaps every patient who thinks about prosthetics asks the question: “Which dental crowns are better?”. Once again, we remind you that any decision, including the choice of crown material, should be made jointly by the doctor and the patient. A conscientious dentist will always talk about best crowns on the front teeth, about all options for prosthetics, as well as about the pros and cons of one or another option specifically in your case. Thus, the best dental crowns are those recommended by your doctor. If we are talking about the advantages of materials, then, without a doubt, all-ceramic crowns, made by pressing or by manufacturing on refractory models, are in the lead. They are ideal for anterior restorations from an aesthetic point of view, as they accurately reproduce the color and translucency of natural enamel, and are strong enough to withstand the same chewing load as the patient's natural teeth.

Restoration of dental crowns

Prostheses, like natural teeth, need care - thorough oral hygiene and restoration of dental crowns. Service life and the need for repair depend on the material. Structures made of ceramics and cermets are prone to the formation of defects. Zirconia is more durable and cannot be broken or scratched. A zirconia prosthesis lasts about twenty years and does not need to be repaired. As a rule, the indications for the restoration of the crown of the tooth are chips, cracks and discoloration of the structure. Only a specialist should carry out the procedure, experiments at home often lead to breakage of the prosthesis or damage to healthy teeth.

What to do if the crown fell off the tooth?

The prosthesis may fall out when installed on low-quality cement or in violation of the manufacturing technology of the structure itself. If a tooth crown has fallen off, you should make an appointment with the dentist as soon as possible. The specialist will diagnose, find out the cause and offer options for further action.

In anticipation of a visit to the doctor, you should rinse and disinfect the prosthesis, clean the tab. You can try to install the structure in place if the process does not cause discomfort and pain. Dental cement sold in a pharmacy will help to temporarily fix an artificial tooth. This measure is necessary to prevent food and bacteria from entering the dental cavity before consulting a specialist. In the case when the crown fell out of the tooth along with the tab, it is recommended to seal the damaged area with cement gel - the resulting “filling” will also protect against infection.

If the crown of the tooth is broken, and not flown off, you must carefully remove a piece of the prosthesis and treat the sharp edge with pharmaceutical glue to avoid injury.

Important! It happens that the dental crown fell out, and the patient swallowed it. Then you should immediately contact the dentist. The prosthesis material is non-toxic, but sharp edges can damage the esophageal mucosa.

When choosing a clinic and a doctor to install a crown, it is important to understand that a quality product cannot be cheap and made in one day. Incorrectly manufactured and installed orthopedic construction can cause various complications in the form of periodontitis, malocclusion, damage to contact teeth and other unpleasant problems. If you feel any discomfort or pain after the crown is placed, you should immediately seek help from your dentist.

Types of metal crowns

If you contact a specialist in order to install a metal crown, you will be offered two options, depending on the method of its manufacture:

• Stamped. Standard sleeve, which is processed with a special apparatus to give it the desired shape.
• Solid cast. It is made according to individual casts by firing in a kiln. It has thicker walls, which positively affects the service life.

They are made from noble (gold, palladium, silver, platinum) and base metals (steel, nickel and chromium alloys). Due to the metallic color, only the side teeth are prosthetized with them, which are not visible when talking. Ideal for prosthetics of chewing teeth, as they withstand heavy loads.

Stamped crowns

These are prostheses that are made from factory sleeves, which are given the desired shape. They have thin walls, so there is no need to grind a large amount of tooth tissue. They are installed if there is no destruction of the roots and at least a third of the tooth crown is preserved.

To create them, use stainless steel or gold.

Ease of manufacture led not only to low cost, but also to a short service life of products. Gold stamped crowns are made from an alloy, 90% of which is gold. For the chewing surface, gold of a lower standard is used to increase its resistance to mechanical stress.

Manufacturing steps:

During manufacture, firing is carried out several times in order to make the metal more dense and intractable. The prosthesis should not have cracks and irregularities.

Indications for the installation of a stamped crown

Stamped crowns set:

• For temporary prosthetics milk tooth before replacing it with a permanent one.
• As a supporting element when installing a bridge prosthesis.
• When a tooth is damaged by caries or injured so much that it cannot be restored with a filling.
• To protect a healthy tooth if a clasp prosthesis is installed on it.

A more durable option for prosthetics is the installation of a one-piece cast crown made of cobalt-chromium alloy. As the name implies, they are cast completely, and not in parts, like stamped ones. The indisputable advantage of a cast crown is the absence of solder joints, which makes it particularly durable. It fits snugly to the turned tooth, preventing the cement from dissolving and reducing the risk of food getting under it. The term of wearing is 15-20 years.

Modeling a solid crown includes several stages:

1. Tooth preparation. Sanded off from 0.3 to 0.5 mm of tissue.
2. Making casts, including adjacent and opposing teeth.
3. Creating a wax cap by stretching.
4. Casting a prosthesis.
5. Metal surface treatment. Fitting, finishing, polishing.

Types of cast crown

Now, several types of solid crowns are installed in the dentist's office:

• Without spraying, these are ordinary metal-colored crowns.
• Sprayed. If the patient is not satisfied with the low level of aesthetics, at his request, the crowns can be coated with a coating that imitates gold.
• With lining. Even more aesthetic are crowns lined with ceramics. Their front part is covered with a ceramic overlay. If you have just such a prosthesis installed, be careful while eating, as ceramics tend to chip off.
• Combined. With combined prosthetics, part of the crowns is lined with ceramics, and the rest, which are not visible when smiling, are installed without facing.

How metal crowns are installed

Installation is carried out in two stages:

• First, the crown is temporarily installed so that the dentist observes the reaction of the tooth.
• If the patient does not experience pain, at the next appointment it is removed, the temporary cement is cleaned and installed again, but with the help of glass ionomer or zinc phosphate cement.

If after the first installation it turns out that it causes discomfort to the patient, it is removed and processed again.

Properly made and installed metal crown:

• It has a smooth, polished surface.
• Contacts with opposite and neighboring teeth.
• Mimics the anatomical shape of a real tooth.
• Tightly adheres to the neck of the tooth.
• It plunges into the periodontal groove by 0.2 mm.

Contraindications

In some cases, the installation of a metal crown is contraindicated or not recommended:

• Due to low aesthetics, they are not installed during prosthetics of the front teeth.
• The presence of an allergic reaction to alloys.
• Significant damage to a living tooth.
• Bruxism.
• Impaired occlusion of the dentition.

Damage to a metal crown

In some cases, a metal crown can be harmful:

Price

An ordinary solid crown costs 3,500 - 4,000 rubles; with spraying - 4,500 - 5,000, but the cost can reach 9,000 rubles. Stamped from base metal - about 2,000 rubles; from stamped gold - about 6,000 rubles.

If you want to know which crown is better to install - solid or stamped, contact a prosthetic specialist at one of your local dentistry. The list of the best dentists in your city is presented on our portal.

When to use

The coating is used not only in prosthetics, but also in dentistry. With a strong destruction of the enamel, a special paint is applied to the teeth, which protects the enamel from further destruction and provides excellent aesthetic performance.

During prosthetics, metal structures are covered with a white substance from above. This allows you to use them for the front group. Zirconium-coated structures are also used. In this case, the material is a zirconium mass, which is evenly distributed on a metal base. Such a material is a barrier to the penetration of metal particles into oral cavity, thereby minimizing the risk of an allergic reaction to the metal.

Varieties of alloys

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

The disadvantage of such designs is that they are too expensive, they are not available for 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 there are high aesthetic indicators.

The advantages of cladding devices 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 on the neck of the tooth, so that the patient does not feel a foreign object in the mouth.

The indisputable advantage of such dental devices is also the fact that during their operation the taste sensations do not deteriorate, since there is no metallic taste in the mouth, which cannot be said about traditional structures made of dental steel. Which device to choose for the restoration of the dentition, the doctor decides based on the state 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 everyone.

Beautiful teeth are a visiting card of a person. It has been proven that people who are not ashamed of their smile and have straight and healthy teeth are much more successful both in their professional and personal lives. Not every person can boast that mother nature gave him a perfect smile.

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

Features of a cast crown in dentistry

The popularity of solid metal crowns is well founded. The manufacture of such metal crowns is made strictly according to individual orders and from a certain alloy. Your dentist will help you choose a crown. In addition, it is recommended to visit an allergist to check the reaction of your body to the installation of such a crown.

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

Gold is a very ductile metal, resembling tooth enamel in its properties. Gold wears at the same rate, and 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

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

The main indications for fixing a cast crown include:

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

Unfortunately, a one-piece crown is not for everyone. Be sure to check with your dentist before installing it for yourself.

The wrong way surgical treatment teeth can be harmful. Important contraindications to the installation of a cast crown:

• children and young adolescence;
• pregnancy in all trimesters;
• breastfeeding period;
• the presence of acute allergic reactions to the components of the alloy;
• 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. Metal-ceramic looks very natural and is highly durable.

Types of casting products:

1. Without spraying. This is a cheap and simple version of 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 lining. This option looks very nice on the front teeth, but lasts even less than the stamped steel variation.

Advantages over stamped and metal-ceramic crowns

A stamped crown is not superior to a solid cast crown. This is a long-gone procedure, which is not carried out in all clinics in the country. Appearance A stamped crown is a small cap that covers the treated tooth from above. The stages of manufacturing a stamped crown can be clarified with a doctor.

Significant advantages of cast construction:

• smooth and even surface;
• longer service life in contrast to the stamped crown;
• stamped crowns cannot fit snugly to the tooth, unlike other designs;
• less risk of infection.

Important advantages of a one-piece cast crown, compensating for the disadvantages of other methods:

Construction manufacturing process

It is believed that all-metal, stamped and metal structures are easier to manufacture than a cast product. However, the aesthetics of metal teeth are much less. To make an original, individual and comfortable to wear design, you must perform the following sequence of actions:

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

Stages of installing crowns on teeth

The installation process, in which a person receives their prostheses, is lengthy and can take from several days to several weeks. Metal-composite and non-metal structures are installed a little faster than solid ones. Gold ones take a little longer, soldering takes a long time. The main stages of the procedure:

Caring for a cast crown

In order for your dentures to shine white not only after they are installed, but also for a long time, it is necessary to take special care of your oral cavity throughout your life. Iron prostheses are more susceptible to bacteria, which is why you should not neglect the daily cleaning twice a day. It will also be useful to use a special balm.

Smokers will have to give up their bad habit: oral health and cleanliness are at stake. You should limit the use of coloring drinks and food: 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 was successful, it is necessary to visit dentistry every six months, where they do professional cleaning teeth. Gold teeth and bridge structures require mandatory care by a specialist.

Dentures will serve you faithfully for many years of life, if you follow the instructions of a dentist and do not ignore morning and evening hygiene procedures.

Price

A one-piece cast crown, made of plain chrome or nickel, without sputtering, will cost you about two or three thousand rubles. Coated metal crowns cost about five thousand rubles. If you want to install an exclusive gold or platinum alloy, the cost of manufacturing such a one-piece crown will increase significantly.

If you want to change your smile and restore the lost function of your teeth, you should 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 for consultations. Acting in this way, you can protect yourself from poor-quality work, and new teeth will last you much longer.
