Alloy of stamped crown. Stamped crown: manufacturing, advantages and disadvantages. Caring for installed stamped crowns

Stamped crowns are one of the types of metal crowns that are made by stamping. It is a structure that follows the shape of the tooth and is used in case of destruction of the tooth crown to prevent further destruction. The crown restores all functions of the tooth, except aesthetic.

Pros and cons

Like all orthopedic structures, stamped crowns have their advantages and disadvantages. In modern dentistry, such crowns are used extremely rarely due to one big drawback - low aesthetic properties.

But they are suitable for prosthetics of lateral teeth, as they are sufficiently durable, invisible to others and have a low cost. Before treatment, the doctor talks about the pros and cons of crowns, offers all possible treatment options and alternatives. The advantages of structures of this type include:

Effective restoration of chewing function;
Restoration of tooth shape;
Distribution of chewing pressure;
Simple and fast manufacturing process;
Does not require preparation of a large volume of tooth tissue;
High strength;
Durability
Low cost.

The disadvantages of crowns include:

Low aesthetic qualities;
The risk of developing galvanosis - electric currents in the mouth, which are accompanied by unpleasant symptoms;
Washable after prolonged use;
The color of the metal is different from other teeth and is noticeable to others;
Risk of developing secondary caries under the crown.

Materials

Metals and their alloys are used to make such crowns. To improve aesthetics, crowns are coated with precious metals - gold or silver. Gold crowns are made if there is an allergy to other dental materials, but this design will be expensive. For production, dental technicians use materials such as stainless steel, nickel and chromium alloy, and gold.

Review (Pavel, 55 years old): “I perform lower jaw prosthetics using stamped metal crowns. They are very reliable and last a long time. A friend of mine had a stamped crown for more than 10 years until the root of the tooth was exposed. Of course, the crowns don’t look very nice , but they were placed on my side teeth and they are not noticeable during a conversation. Crowns covered with ceramics were installed on my front teeth, the teeth are beautiful, but expensive."

Manufacturing

The production of crowns involves the collaboration of a dentist together with a dental technician. The clinical steps are performed by a doctor, and the laboratory steps by a technician. Clinical manufacturing stages:

Preparation of the oral cavity (treatment of caries and other diseases);
Tooth preparation (grinding the tooth tissue to the thickness of the future crown, removing 0.5 mm of enamel from all sides of the tooth);
Taking impressions of the jaws;
Choice of crown color or coating;
Fitting and correction of the finished design;
Fixation of the crown.

Stages of making a crown in a dental laboratory:

Casting jaw models using silicone casts;
Fixing models in the occluder in the position of central occlusion;
Wax construction modeling;
Production of plaster and metal stamps from metal alloys;
Selection of sleeve for stamping;
Stamping a metal crown from a sleeve;
Grinding and polishing of the crown.

Each manufacturing stage is important, and in order for the finished crown to meet all requirements, it is necessary to adhere to all rules and standards. The quality of the crown will depend on the type of materials, the professionalism of the doctor and dental technician.

Review (Ekaterina, 40 years old): “I had a metal crown on my side tooth for many years and it didn’t bother me. But recently I began to notice an unpleasant taste in my mouth, a burning sensation and tingling sensation on my tongue. When I went to the dentist, they told me that the reason was crown disease and recommended changing it. I had root canal treatment and a crown based on zirconium dioxide was installed, the unpleasant symptoms of the disease disappeared."

The service life of the structure will depend on hygienic oral care, quality of design, and operating conditions. In order for the structure to last for a long period, it is necessary to carefully care for your teeth, carry out timely treatment of oral diseases, and visit a specialist for a routine examination.

Installation

Installation of a stamped crown is the last clinical stage of prosthetics. Before fixing the structure, the doctor examines the finished structure for defects and checks the crown in the oral cavity. If the crown goes too deep under the gum, then traumatic gingivitis will occur in the future, so the doctor immediately corrects the crown.

To do this, the structure is shortened using a bur or scissors. If the crown is not long enough, food will get clogged between the tooth and gum, causing caries and gum inflammation. In this case, the dentist sends the crown for correction and the technician makes a new product. The dentist checks the design to ensure that it meets the following requirements:

Densely covered the neck of the tooth on all sides;
Didn’t go deep under the gums;
There were no manufacturing defects (pores, cracks);
Restored the shape and function of the tooth;
She was in the correct bite.

If the crown is made correctly and meets all the requirements, then the doctor installs the structure on the tooth. To do this, treat the crown and tooth with alcohol, dry and isolate the tooth with cotton swabs. Prepare and apply special cement, put on the crowns and fix them in this position until the dental cement hardens. After treatment, the patient is given recommendations on how to care for the crowns.

Stamped crowns are the simplest and cheapest method of permanent prosthetics and restoration of damaged teeth. A stamped crown is made in the form of a thin-walled cap, which is adjusted to the anatomical shape of the tooth. The design is only 0.2-0.3 mm thick and is made of nickel-chrome alloy or gold. The technology has been tested in dentistry by many years of practice; such crowns have been successfully used for more than 100 years and still remain in demand. The main advantages of stamped crowns:

Due to the thinness of the walls of the crowns, the teeth practically do not need to be ground down. This is especially true in cases where a crown is installed on a healthy tooth that remains almost undamaged.
The crown is placed on a living tooth, and pulp removal is not required.
The optimal solution in situations where it is difficult to use other prosthetic methods.
Ease of manufacture results in a lower cost compared to other crowns.

Dentists recommend installing stamped crowns for defects in the coronal part of the tooth and destruction of baby teeth, if it is impossible to make an inlay or filling. Such crowns are suitable for protecting healthy teeth that are planned to be used as a support for a bridge or clasp prosthesis. Also, structures are placed when the teeth are insufficiently strong, which cannot be ensured even with careful treatment.

Stamped crown installation service

Dental center "Eurodent" offers the services of qualified specialists at reasonable prices. Stamped crowns are the cheapest designs in the center's pricing policy. Crowns are made by stamping and fixed in the mouth using a thick layer of special cement. The materials used are stainless alloys and precious metals.

The process of creating a stamped crown involves several main steps:

taking an impression of the patient's jaw,
modeling of future design,
receiving one or more stamps,
production of the crown itself,
final processing of the product - polishing and grinding,
installing a crown on a tooth and securing it with cement.

Prices for stamped crowns

When choosing crowns, price plays a significant role. Stamped crowns are an affordable option that fits almost every patient's budget. Such designs compare favorably in cost to the proposed alternatives. You can get accurate information about installation features and prices during a consultation with a dentist at the Eurodent center.

Dental products called stamped crowns can safely be called a relic of the past. These metal structures can be seen in middle-aged and elderly people, since young people have the opportunity to use modern and advanced methods for correcting certain defects in the oral cavity. The most common base for making stamped dental crowns is metal. The initial goal that guided the process of creating metal structures was to restore the damaged structure of the teeth and restore their lost function.

At one time, the simplicity and cost-effectiveness of manufacturing these products made dental crowns the only way to restore dentition. The design of these dental units is made in the form of a metal cap, which is easily fixed on the surface of the damaged tooth. There are two main types of crown manufacturing, one of which involves the use of special spraying, and the second does not. If a metal product was made using sputtering technology, then inert metals such as gold and silver are used for this purpose.

The most popular are those stamped with gold plating, since some patients perceive these products not only as an orthopedic structure, but also as decoration.

zirconium crowns.

Given modern progress in dental practice, such primitive products began to rapidly lose their relevance. The rapid refusal of people to use stamped crowns is due to their unaesthetic appearance. Most patients prefer to use modern dentures, which do not differ in appearance from other teeth in the mouth. Despite this, there remains a small percentage of people who consciously choose this type of dental prosthetics.

What materials are they made from?

The standard base for making crowns is metal, which is subsequently coated or not coated. Inert metals such as silver and gold are used as sputtering materials. In Soviet times, patients preferred to install stamped prostheses made without the use of spraying. Such products had low cost, increased strength and ease of installation. The consequences of installing metal structures were an unsatisfactory aesthetic appearance, as well as the occurrence of a condition called galvanism. With the development of progress in dental and orthopedic practice, dental crowns began to be made from a plastic base, as well as ceramics. The appearance of such products is as close as possible to natural human teeth.

Indications for installation

Like any medical procedure, the installation of such prostheses must be carried out in accordance with the indications. This type of denture may be recommended in the following cases:

As protection for abutment teeth in patients planning to have bridges installed
If there is damage in the coronal part of the tooth to restore it as a functional unit
In pediatric dental practice to protect baby teeth from rapid destruction
To protect a healthy tooth from external negative factors during the planned installation of a clasp denture

In the Soviet past, people installed gold-plated prostheses not only for therapeutic purposes. These products were regarded as an indicator of social and financial well-being.

Installation steps and preparation

At the laboratory stage, the process of manufacturing stamped metal crowns includes a number of such sequential manipulations:

The model is made of plaster according to a previously taken cast.
Next, the dentist forms a gum model by layer-by-layer application of special molten wax.
The penultimate stage is selecting the required sleeve and giving the required shape
The final stage is the production of a metal crown by stamping it. The finished product is sent to a dentist for subsequent installation.

At the clinical stage, the process of installing dental crowns includes the following steps:

Preparing a damaged tooth for installation (grinding)
Selection of the color of the microprosthesis depending on the individual characteristics of the patient’s enamel
An impression is taken of the damaged tooth on which the stamped metal prosthesis will be installed.
The finished impression is sent to a dental technician to make a crown.
The finished crown is tried on the ground tooth, and adjustments are made depending on the nuances that arise.
After the metal prosthesis meets the requested parameters, it is securely fixed over the ground tooth

As mentioned above, a prerequisite for the correct installation of a stamped metal crown is the preliminary preparation of the tooth on which the product will be installed and its depulpation (nerve removal). The preparation process itself involves selective removal of a thin layer of tooth tissue. This technique includes the following steps:

Primary tooth treatment is carried out using so-called diamond wheels, which remove no more than 0.5 mm of dental tissue. The thickness of the removed layer directly depends on the presence or absence of spraying, as well as the material from which the prosthesis was made
At the second stage of preparation, the medical specialist checks the space located between the prosthetic tooth and its antagonist. For this purpose, a wax strip is used, which the patient is asked to bite. The finished wax impression is assessed by the dentist
At the third (penultimate) stage of preparation, the proximal surfaces of the tooth are processed. To achieve this goal, special discs made of diamond material are used.
At the final stage, the dentist prepares the palatal and buccal surface, which gives the dental stump a cylindrical shape

There is also a list of nuances that must be taken into account when installing and manufacturing this type of dentures. Such nuances include:

The installed prosthesis must fully compensate for the functionality of the damaged tooth, as well as restore its chewing function as much as possible.
The finished crown should fit tightly around the neck of the damaged tooth. If the product is too wide, then over time irritation of soft tissues will form, followed by gum atrophy
The penetration into the groove should not be carried out to a depth of more than 0.3 mm. If this figure is increased, the patient will develop acute marginal periodontitis
The stamped metal product must fully replicate the anatomical shape and structure of the damaged tooth. The product must contain equators and all existing tubercles

If the listed conditions were met during the manufacture and installation of the prosthesis, then its operation will be as comfortable as possible, without the risk of complications.

Pros and cons

Like any medical product, stamped crowns have a number of advantages and disadvantages that must be taken into account before choosing this prosthetic technique. Having decided to install one or more of these dental products, the patient can safely count on the following benefits:

Crowns are made in a short period of time and have a simple design
The cost of the products allows us to classify the stamped version of crowns as budget options for prosthetics for damaged teeth. The price of such products is an order of magnitude lower than prostheses made of metal-ceramics and plastic.
Compared to porcelain products, stamped ones involve preserving a larger volume of natural tooth tissue.

Along with a few advantages, there is a whole list of disadvantages that do not characterize this option of prosthetics from the best side. The main disadvantages of stamped crowns include:

The risk of secondary caries increases significantly, since even professional installation of the product does not guarantee its tightness
Patients with metal crowns often develop galvanism, or the generation of electrical impulses in the mouth. This condition occurs as a result of a chemical reaction
Even modern dental equipment is not capable of imparting the physiological structure of a tooth to stamped crowns. In most cases, such teeth do not have fissures and the tubercles are not clearly visible.
Low level of aesthetics, which is not compensated even by coating with expensive metals
Rapid wear due to its manufacture from soft metal

Despite the fact that during a medical consultation, a dentist can tell a person about all the advantages and disadvantages of this method of prosthetics, the final decision is always made by the patient himself.

Caring for this type of crown

After a patient has had one or more metal stamped dental crowns installed, they are advised to continue with their normal oral care routine. There are several key tips that will help keep your mouth in good condition and extend the life of your dentures. Such recommendations include:

In order to remove food debris from the interdental spaces, it is recommended to use hygienic dental floss, which can be purchased at a pharmacy or in a specialized store.
Every day in the morning and evening it is necessary to clean the oral cavity with a toothbrush and toothpaste. In order not to injure tooth enamel and gum tissue, it is recommended to choose toothbrushes with a medium level of hardness. The frequency of brush replacement is once every three months.
In order to avoid intensive proliferation of carious microflora, after each meal or smoking a cigarette, it is recommended to rinse the mouth with boiled water or a special liquid.

After 3 months from the date of installation of the denture, it is recommended to visit a dentist for a revision of the denture. Regular visits to the dentist will help you avoid such a terrible complication as secondary caries, which forms when the sealing of the denture is broken.

Service life

Considering the thickness of the material from which stamped dental crowns are made, the service life of such products does not exceed 3 years. During this period, stamped dentures literally wear out to holes, so most dentists recommend that their patients annually replace old ones with new ones.
If you do not adhere to this rule, then a gap is formed between the tooth and the denture, into which food fragments get clogged, carious microflora multiplies and secondary caries occurs.

If all the nuances of manufacturing, installation and operation of stamped crowns have been fully observed, then a person can successfully enjoy the benefits that this type of prosthetics gives him for many years.

We recommend that you familiarize yourself with information about more modern and safer analogues - for example,

The legacy from the old denture school left us with this type of correction of defects and restoration of the dentition, such as stamped crowns. Despite the outdated technique of such dental prosthetics, they are not giving up their positions.

stamped crowns are used in the cheapest form of dental prosthetics. They are made from mass-produced industrial metal caps of an average shape, from which a crown imitating a tooth is then made by hammering and stamping.

The thickness of the walls of such a cap is from 0.1 to 0.3 mm, so that, using the appropriate tools, a dental technician can quickly make a crown from it. But it makes sense to do it only if the remainder of the tooth on which it is placed remains at least 1/3 of the original size.

When making an impression of the jaw, the dentist can always recreate on a model the shape of a missing or severely damaged tooth. Then, based on the impression made, we will make a crown from a blank cap, selecting it according to size.

Alas, modern methods of dental prosthetics are also the most expensive, unaffordable for the vast majority of the population. It is impossible not to have prosthetic teeth. Anyone who is missing even one tooth, let alone several, will confirm that digestive problems very quickly arise due to the inability to fully chew food.

Functions of metal crowns

Recreating the shape of a tooth damaged or damaged by caries.
Restoring chewing function, and, as a result, improving digestion.
Restoring speech intelligibility.
Aesthetic: even metal in the mouth is preferable to a hole where a tooth should have been.

Materials

Stamped crowns are made from 900 gold or special stainless steel (grade 1x18N9T), which is easy to melt and forge. If the factory stamped sleeve is made of gold, then, due to the softness of this variety, the cutting edge is soldered from metal of a different standard - harder 750.

But usually gold crowns are no longer placed. And yellow metal crowns, manufactured in modern dental prosthetic workshops, are made by sputtering titanium nitride onto steel blanks, imitating 900 gold.

In addition to steel and gold, blanks made of platinum, an alloy of cobalt and chromium, silver-palladium and titanium can be used.

Indications

Typically, stamped crowns are placed when the natural parts of the tooth can no longer be restored with fillings or inlays. This usually happens when more than 1/3 of the tissue is removed along with caries.

Except in cases of caries or impact trauma, stamped crowns can be placed as bridge abutments. This allows you to avoid grinding down excessively healthy teeth, or when it is impossible to install a cast structure.

Sometimes such crowns can even be placed on children’s baby teeth to correct their bite.

"Pros" and "cons"

Pros

The first (and often the decisive) plus is accessibility. The cost can only be compared with plastic products. The average cost of manufacturing and installing one crown without coating (a metal prosthesis without cladding) is about 2,000 rubles in Moscow. With spraying - more than 2200. With different types of linings that hide the metal (linings can be plastic or ceramic) - from 2600 to 5,000.
The thickness of the walls does not exceed 0.3 mm, which means that, taking into account the additional layer of cement, no more than 0.4 mm is removed from the tooth. That is, depulpation is not performed.
Speed of production and ease of installation.
Over the century of use of the method, there are literally isolated cases of rejection of installed crowns as a result of incompatibility of tissues with metals.

Cons

Unaesthetic - metal in the mouth, even if it is gold, does not correspond to modern concepts of beauty.
Insufficient strength of the walls, due to which it quickly grinds down and wears out, allowing infection to penetrate inside.
Galvanosis is possible - the occurrence of a weak electric current as a result of the impact of acids contained in food and saliva on the metal of the crown.
The functions of the teeth are not fully restored, and this affects the degree of grinding of food when eating it.
In cases of “sinks” in the cement layer, aggressive media from food will penetrate to the pulp.
Anatomical features are not taken into account, which results in incomplete adhesion of the surfaces of opposing teeth.

How are dentures made?

Therapeutic treatment of the tooth is carried out after its preparation.
An impression of both jaws is made using plaster or alginate. Plaster impressions are gradually becoming a thing of the past as obsolete; the use of alginate is preferable.

After this, the dentist begins to work closely in the dental laboratory.

He is given a model of the dentition of both jaws cast in plaster, on which, in case of problems with the bite, the central relationship for its correction is determined.
Plaster of Paris is placed in the occluder.
A plaster stamp is cut out of the wax model that is then created, and then a metal one is made according to its sample.
The sleeve-blank is selected as precisely as possible according to the size of the cast die.

The fact is that the sleeves are produced according to average parameters, and in order to fit the prepared stamp exactly to the tooth stump, there are two ways: choose the exact size or reduce it from the available ones. The sleeve is put on the second die and the fitting work begins, which includes thermal and mechanical effects on the workpiece.

The final check of the finished crown is done in the clinic, where, after fitting, they look at how tightly it fits (without taking into account the future cement layer) to the neck of the tooth. Defects are identified, then the outer surface is ground. If the patient expresses a desire, titanium nitride will be sprayed onto the steel surface.

At the last stage, the finished crown is dried using alcohol treatment, the cement is diluted and injected inside, and it is forcefully pressed onto the tooth stump. To do this, you just need to clench your jaw tightly. The squeezed out excess cement is removed.

Crown preparation

Since the crown has walls of a maximum of 0.3 mm (this is practically dense steel foil, with the ability to cut it with scissors), a small amount of dental tissue is prepared. The stump is ground to a cylindrical shape; only on the occlusal surface and in the neck area is the relief maintained according to the location of the enamel.

The surface is treated with diamond wheels of different diameters, removing a layer of 0.5 mm. A difference of 0.2 mm is made for the use of cement under the crown.
The distance between the prosthetic tooth and its antagonist on the opposite jaw is constantly checked. To do this, a wax strip test is used, on which, after clenching the teeth, an impression appears, from which the doctor is guided as to the need for modifications to the structure.
The preparation of the proximal surfaces of the tooth is done - that is, those lateral parts that face the neighbors.
The buccal and palatal area is treated last, giving the stump the shape of a cylinder. This will make it easier to install the prosthesis and fix it more reliably. The cylindrical surface will also make it possible in the future, when it is time to change the crown, to easily remove it without particularly damaging the stump.
There should not be a large gap when the edge of the crown touches the dental neck. Ideally, its edge should slightly touch the gum or even sink into it, but no more than 0.3 mm. This will not prevent food debris from getting under the crown, but there will still be less of it than if there was a gap.

The need to replace crowns may arise within 2-4 years. Because no matter how carefully the cement layer is applied, sooner or later aggressive environments from food and saliva, microorganisms, and toxins formed in the mouth overnight will begin to penetrate into the space between the tooth stump and the crown.

The cement itself, under the influence of many factors, gradually breaks down, dissolves and is washed out from under the crown. A gap is formed where food particles get clogged. All this begins to gradually destroy the tooth, either causing caries, or demineralizing it, making it fragile.

Caring for installed stamped crowns

Since in the process of using such dentures, sooner or later the marginal fit changes and a gap is formed between the neck of the tooth, gum and crown, special care measures are required for them. Hygienic care rules include the following:

Brushing your teeth – at least 2 times a day. Using a brush with medium-hard bristles is mandatory. The paste is selected with the appropriate mineral composition.
Be sure to rinse your mouth after eating.
Use dental floss to clean the space between your teeth.
No later than 3 months after the installation of the dentures, visit the doctor who installed them. Make such visits once a quarter a rule, until the very end of the service life. This way you can notice negative changes under the crown in time: the beginning of the carious process, tartar deposits, inflammation. And take treatment measures before the process goes too far and the crown has to be removed.

Conclusion

Leading global and domestic clinics no longer practice making prosthetics using stamped crowns. Thus, provincial clinics become the last refuge of these technologies. But they also focus (quite rightly) on the solvency of their clients. Therefore, they will apparently be in use for many more decades.

In modern orthopedics, stamped crowns are used quite rarely, which is due to their low aesthetic and functional qualities. However, reasonable price and ease of manufacture make these products accessible to all categories of citizens. Before making such a prosthesis, you should familiarize yourself with the features of the installation procedure and the rules for its further operation.

Stamped crowns are made from metal blanks, which are stainless steel caps. Before installation, a protective coating of silver or gold is applied to the caps to prevent oxidation of the crowns. Some dental technicians make plastic-lined steel crowns that look more natural. You should not use products made entirely of gold, since this metal does not have the necessary hardness, which leads to rapid wear of the prosthesis.

They can be used to restore a tooth damaged by caries or various external influences. If for some reason it is impossible to install a cast support frame, then “stamping” can fulfill its role. Stamped products are occasionally used in pediatric orthopedics, before the replacement of milk teeth with permanent ones.

Advantages and disadvantages of stamped products

Stamped metal products for oral prosthetics have their advantages and disadvantages. In addition to ease of manufacture and relatively low price, several more positive qualities can be highlighted:

since the thickness of the stamped crown does not exceed 0.3 mm, there is no need to remove a large layer of hard tissue from the diseased tooth;
this type of prosthesis can be installed without first removing the nerve;
Thanks to quick production and easy fixation in the oral cavity, the prosthetic procedure takes little time;
the versatility of the prosthesis allows you to install a crown even when other methods of prosthetics are not possible.

In the last century, medical presentations and scientific reports were devoted to the topic of metal dental crowns. Modern methods of dental correction and the use of the latest materials in orthopedic dentistry have almost completely replaced “stampings” from the field of dental prosthetics. Stamped products are abandoned for several reasons:

the medical cement composition, which serves for reliable fixation of metal caps, quickly dissolves under the influence of external factors, which leads to the formation of gaps between the tooth and the crown;
a loose fit of the “stamping” is fraught with clogging of the resulting gap with consumed food and the development of caries;
metal does not have the same high strength characteristics as modern materials and wears out over time.

In addition, metal teeth present in the mouth are unlikely to brighten anyone's smile. Today it is quite difficult to find a clinic that manufactures and installs such prostheses.

Manufacturing stages

The creation of a prosthesis is carried out in close cooperation between a dental technician and an orthopedic surgeon. The technology for manufacturing stamped crowns includes several clinical and laboratory stages:

a thorough examination of the oral cavity by a dentist and carrying out preparatory measures, which include caries removal and root canal treatment;
removal of the upper tooth tissues with a drill;
choice of crown color, depending on the patient’s wishes;
taking impressions of both jaws, which is necessary for accurate fixation of plaster models;
making models using the obtained impressions;
installation of the obtained models to determine the correct location of the upper and lower dentition;
modeling of the future design by a dental technician;
making a metal stamp;
choosing a sleeve suitable for the tooth and giving the cap the desired shape;
stamping the product and handing it over to the dentist;
fitting of the prosthesis and carrying out corrective procedures.

The final stage is fixation in the oral cavity using dental cement. For some time after prosthetics, the patient may feel a feeling of discomfort in the oral cavity, which usually goes away after 2-3 weeks.

Tooth preparation

After processing, the tooth takes the shape of a cylinder. Its diameter should not be larger or smaller than the hole in the “stamping”.

Important nuances in the prosthetics process

Compliance with a certain number of rules during the installation of “stamping” will help extend the life of the prosthesis. There are several nuances that must be taken into account when using prosthetics with stamped crowns:

The crown should be placed on the prepared tooth with little effort, which will prevent further injury to the marginal gum and eliminate possible complications.
The metal cap should not sink into the gum more than 0.3 mm. With deep immersion, inflammatory processes are possible, leading to loosening of the tooth.
To ensure proper chewing function, it is necessary that the crown fits tightly with the opposing teeth.

A correctly executed crown is characterized by the presence of a realistic surface. After installing the prosthesis, the dentist must ensure that the metal cap does not rise above the adjacent teeth. Failure to comply with this rule can lead to pain when chewing food, as well as to loosening of the tooth and its subsequent loss.

Care rules and service life

After dentures, the patient should follow standard preventive oral care procedures, which include regular brushing of teeth and rinsing the mouth after meals. After 2-3 months from the date of surgery, you must visit your doctor again to be sure that the prosthesis is functioning normally. Every 6 months you will have to have your teeth professionally cleaned. This procedure will help prevent the appearance of caries under the “stamping”.

The service life of metal crowns is significantly less than that of modern ceramic or plastic implants, and is estimated at 3-5 years. This short service life is due to the softness of the material used in manufacturing. Dentists advise replacing old metal crowns with new ones every 3-4 years.
