Metal ceramics or metal-free ceramics: what to choose

Installing crowns is one of the most effective ways to restore teeth. How can you determine that the prosthesis is of adequate quality and that the fixation procedure was carried out according to all the rules? It’s very simple: artificial teeth should not be visually different from real teeth. By and large, such a result can only be achieved if two conditions are met: the doctor installing ceramic crowns must be a true professional, and the structure itself is made of solid ceramics. Andrey Nikolaevich Karneev, leading orthopedist at the German Implantology Center, spoke about what a ceramic crown on a tooth is.

Metal-plastic crowns

Such prostheses are called conditionally temporary crowns. A cost-effective prosthetics option that involves installing crowns with a metal base and a plastic coating. Traditionally, structures are made of nickel, cobalt, and chromium.

Despite the natural appearance and relatively good functionality, it is not worth wearing such prostheses for a long time: the product quickly loses its whiteness, slightly increases in size and needs to be replaced.

Among the undeniable advantages of metal plastic are its low cost and gentle effect on the enamel layer of the tooth. If the product is slightly deformed, it can be repaired directly in the patient’s mouth. Among the disadvantages of this choice, it is worth highlighting the low strength of the structure and the likelihood of developing allergies.

Zirconium - an alternative to metal ceramics?

Above we compared all the advantages, disadvantages and features of both materials. Based on the information presented, we can conclude that zirconium and metal-ceramic crowns are worthy options for prosthetics, but they are designed for different groups of patients. Metal-ceramics can be used for those patients who value reliability, reasonable cost and do not need ideal aesthetics. Zirconium crowns are chosen by those patients who are most concerned about the aesthetic issue and other characteristics are not so important.

Metal-ceramic crowns

Practice shows that metal-ceramic crowns are deservedly considered the most popular. The base of the product is metal (cobalt, chromium, titanium, gold, etc.). To give the crown an aesthetic appearance, the metal base is covered with a ceramic layer and the elements are connected by exposure to high temperatures.

The popularity of metal ceramics in prosthetics is explained by its obvious advantages:

• Aesthetics. The material with which the crown frame is covered completely recreates the anatomical structure of the enamel;
• Sufficient strength. The products are quite durable due to the cast metal frame - they can withstand normal chewing loads and do not wear out. It is rare to see chipping of the enamel coating. In this case, repair of the prosthesis can be done in the patient’s mouth;
• Versatility. Crowns of this type are installed both on individual fragments of a row, and in the form of a dental bridge.

Since the ceramic layer is completely opaque, the prosthetic fragment (especially with a single restoration) can stand out against the background of natural teeth. Another disadvantage of metal-ceramic crowns is the need to grind the unit, after which it forever loses its original shape.

Main types of metal ceramics

Metal-ceramic dentures consist of a metal base, onto which a ceramic coating is applied layer by layer and fired. Metal-plastic crowns are made in a similar way (the metal base is covered with plastic), but the plastic coating is very fragile and short-lived. Therefore, when the question arises: which teeth are better than metal-ceramics or metal-plastic, metal-ceramic structures always win. Technology using ceramics has made it possible to obtain high strength and achieve good aesthetics of dentures. Depending on the composition of the frame, such crowns are divided into two main types:

• Metal ceramics based on base metal alloys. In this case, cobalt-chromium or nickel-chromium alloys are used. They are inexpensive, but have a dark shade and can change the color of the prosthesis, shining through the ceramic layer of the coating if it is not thick enough, making it noticeable against the background of natural teeth.
• Metal ceramics based on precious metals, the most popular of which is gold. It does not distort the color of the crown; due to its yellowness, it gives the ceramic a warm tint and provides a higher aesthetic result. This is a better metal-ceramic compared to the previous option. However, such prostheses will be somewhat more expensive than them.

Thus, patients who have chosen metal-ceramic crowns can choose the best option for themselves in terms of price/quality ratio.

Metal crowns

These are the predecessors of all other types of dentures. This type of prosthesis is indicated for installation only on chewing teeth, since the structures are noticeable on the front teeth. Metal crowns are made of steel, titanium, platinum, and gold. Alloys containing cobalt, chromium, and silver are also in demand.

In laboratory conditions, stamped or cast products with spraying are prepared for patients. Standard structures take on the desired shape as work progresses. Individual production of the cap guarantees maximum adherence to the tissues, which eliminates rapid abrasion of the material and the spread of bacteria under the prosthesis.

Among the advantages of such products, it is worth noting their exceptional strength (due to the plasticity of the material, a crown made of this type of material does not crack and does not wear out for a long time). However, metal dentures are extremely unaesthetic, can cause allergies, and are difficult to fit on a tooth.

In addition, when using metal prosthetics, it is worth considering that crowns made from several types of metal cannot be used at once. If the patient already has a steel structure in his mouth, in the future he will have to fix crowns only from this material. Otherwise, the patient may develop galvanic syndrome, which is manifested by a burning sensation in the mouth and a “metallic” taste.

Let's compare the disadvantages

The materials discussed in the article have not only advantages, but also disadvantages.

Disadvantages of metal-ceramic crowns

• It is necessary to grind down more of your own tooth tissue due to the large thickness of the walls of the prosthesis.
• Almost always, tooth depulpation is required.
• An allergy to metal (except precious metals) may develop.
• If manufacturing technology is violated, artificial teeth may have a darker color.

Disadvantages of metal-free crowns

• High price.
• Complex manufacturing process.
• Slightly inferior in strength to metal.

Based on the totality of these characteristics, it can be noted that zirconium or metal-free crowns are better than metal-ceramics and can be recommended to those patients who want to get the most beautiful smile.

Ceramic crowns for teeth

Metal-free crowns are deservedly recognized as the most aesthetic: they are extremely difficult to distinguish from natural teeth, even if the gum tissue becomes thinner, the prosthesis remains invisible and looks natural. In dentistry, several types of metal-free dental crowns are used:

1. Porcelain or all-ceramic. They are made according to a personal impression from pressed material without adding other components.
2. Mixed (zirconium dioxide and ceramics). They are stronger than the previous type of prosthesis, have high light transmittance and do not cause allergies.
3. Mixed (aluminum oxide and ceramics). The designs are made of translucent hypoallergenic material, which is comfortable to wear and resistant to temperature changes.

All ceramic products are biologically compatible with mucous membranes and do not tend to cause allergic reactions. Other advantages of the designs include:

• light weight (a crown can be installed even on weakened teeth);
• immunity of ceramics to dyes;
• the need for minimal tooth grinding before ceramic prosthetics.

The disadvantages of this method of prosthetics include the relatively high cost of the products, as well as their fragility. Ceramic structures are not designed for significant chewing loads, which is why they are more often used for prosthetics of the upper incisors.

If you properly care for ceramic products, they will last from 10 to 15 years. At the same time, the prosthetic structure is not susceptible to caries and does not accumulate plaque.

In what cases is it better to install veneers?

Dentists recommend that patients with crooked or unsightly front teeth get veneers. They are very suitable for hiding gaps between teeth. After treatment of a tooth, many observe its darkening, possibly yellowing. Doctors attribute this effect to tissue death or a reaction to dental filling material. Of course, this is unsightly, especially if such a tooth is located in the smile area.

This problem can be easily corrected by applying a veneer. The color of the plate can be chosen so that it is similar to the shade of the entire dentition. Therefore, the selection and installation of veneers is individual in each case.

The method of installing veneers involves light preliminary treatment of the teeth - from 0.2 to 0.7 mm is removed, on which thin plates are subsequently placed. Veneers can be composite or ceramic; the dentist places them exclusively on the facial surface of the teeth. Their service life is from 10 to 15 years.

If you have dental problems described below, then you should contact a good dentist to install suitable veneers:

• interdental space or gap;
• uneven color of the enamel without the possibility of bleaching it (this includes spots, stripes and yellowness);
• unsatisfactory tooth shape or slight curvature, crowding of teeth;
• various defects, for example, cracks or chips;
• tooth decay less than 50%;
• lack of obvious flaws, but the desire to get a beautiful Hollywood smile.

Before deciding to install veneers, patients should learn that such plates are placed in the absence of serious defects and in the presence of all teeth in the front row. If there is a sufficient layer of enamel and the lingual side of the tooth is in order, installation of a veneer is possible, otherwise it is necessary to install a crown.

Veneers will not be installed if there is:

• abnormal bite development;
• pathological abrasion of teeth, thinned enamel;
• bruxism;
• a tooth on which there is a large filling or the main part of the dental tissue is destroyed;
• hobby related to extreme sports.

Considering the above, we can conclude that plates are an excellent solution for patients with healthy teeth.

Zirconium dioxide crowns

Zirconium crowns are prepared in laboratory conditions using high-precision computer equipment. Laser scanning allows for an accurate analysis of the dentition, after which a computer program models an accurate crown for the tooth. Optical data is transferred from the computer to a milling machine, which grinds the prosthesis from the workpiece.

These types of dental crowns are the most expensive. Their price is justified by a number of obvious advantages:

• Strength. Zirconium dioxide is as durable as natural tooth enamel. Even solid bridges can be made on the basis of this material;
• High aesthetics. The shade of zirconium dioxide can easily be matched to the color of the natural enamel layer;
• Biological compatibility. Zirconium dioxide is safe for human health. This type of prosthetics is not contraindicated for patients with metal allergies.

The products are recommended for installation by patients who have high demands on the appearance of structures and want their new teeth to be indistinguishable from natural elements.

Prosthetic options depending on the clinical picture

• If you need to correct the shape, size, color of incisors, fangs, eliminate cracks, small chips, a good solution is ceramic or zirconium veneers. Thin dental onlays (up to 0.3 mm) require minor preparation of the enamel layer. They are fixed to the outside of the teeth with composite glue (bond).
• If there is extensive destruction of the supragingival part ( more than 60%
  ), a dental crown is installed. Before installation, the incisor and canine are given the desired shape (grinded), the root is strengthened with a stump insert (if necessary), the prosthesis is fixed to the support with dental cement.
• If not only the supragingival part is destroyed, but also the root, implantation will help restore full aesthetics and functionality of the dentition. If the clinical situation allows, the implant is immediately loaded with a temporary crown, which is replaced with a permanent one after the implantation of the artificial root.

Immediate prosthetics for single defects is possible only for incisors and canines (up to the 5th premolar). The prosthetic structure is removed from the bite (made slightly lower in height). This is necessary to eliminate the risk of loosening the implant due to the load on the prosthesis.

Gold crowns on teeth

Separately, it is worth noting the type of metal crowns - gold products. In dentistry, pure material is not used in the manufacture of dentures, since gold is a soft metal. Traditionally, an alloy with palladium and platinum is used. The structures fit well, do not irritate the mucous membrane, and do not lead to bleeding gums.

Very often, gold dentures are coated with a ceramic layer. Such products can even be placed on the front teeth: they retain the beneficial properties of the base material and look good.

e.max crowns on front teeth

When considering crowns for the front teeth, we strive to give a clear answer as to which ones are better aesthetically and functionally. The undisputed leader in this direction is Emax glass ceramics. This is an improved modern material, the creation of which is based on the use of lithium disilicate, which has impeccable characteristics. Emax ceramic crowns look perfect on the front teeth because they have light transmission that fully matches natural enamel. The same can be said about veneers made from the above material; they are completely indistinguishable from natural teeth

Today there are 2 known options for Emax materials:

1. E.maxPRESS. Widely used to obtain dentures and veneers. This involves the injection molding method under the influence of pressure and high temperature conditions. Such crowns are indispensable when restoring single teeth or creating short bridge structures.
2. E.maxCAD. In the production of this material, modern computer technologies and computer-controlled machines are used. Such crowns are characterized by less high reliability, which eliminates the possibility of creating bridge structures and ultra-thin veneers. Also among the disadvantages of E.maxCAD is the limited selection of shades, which reduces the chances of obtaining a design identical in color to natural enamel.

Temporary crowns on teeth

Since dental prosthetics requires time, the patient is often given temporary crowns. The patient wears the dentures until the permanent dentures are ready.

We are talking about inexpensive polymer, acrylic, and plastic crowns, which are designed to protect the prepared units from displacement and pathogens. In addition, they perfectly perform an aesthetic function, masking “holes” in the oral cavity.

Temporary crowns can be placed on natural teeth or on implants. Due to these structures, an even distribution of the chewing load is ensured, the risk of jawbone resorption is reduced, and the rate of adaptation to a permanent prosthesis is accelerated.

Alternative options

There are 3 known alternatives to crowns installed in the frontal zone. They are used for partial destruction of natural teeth or loss of 1-2 units.

• Veneers . Such plates are indispensable for the destruction of the outer part of the front tooth. However, in order to understand what is better - veneers or crowns for the front teeth, you should remember that a prerequisite for the use of such corrective onlays is the presence of an inner tooth wall. With the help of veneers, it is possible to obtain good aesthetic results, as well as maintain the maximum size of dental tissues;
• Dental implants . If one or two teeth are missing, bridge structures are usually used to eliminate the deficiency. However, in this case, the dental units closest to the defect are prepared. At the same time, the operational period of prostheses reaches only 10 years. Therefore, the best way out of the situation is to fix the dental systems;
• Use of filling materials . In this case we are talking about the restoration of teeth that have undergone partial destruction. But it is recommended to resort to the filling procedure only if the volume of destruction of the natural crown does not exceed 50%. In other situations, it is advisable to give preference to crowns.

It should be noted that any attempts to restore the integrity of a severely damaged tooth with a filling may result in a root fracture, since metal pins are not able to withstand increased loads.

Ranking of dental crowns by nomination

Metal-plastic crowns

Another name for this type of crowns is combined. The structural structure of the crowns is as follows: a cast metal alloy frame, which is additionally covered with a white plastic mass. The advantage of combined crowns is an affordable price, as well as acceptable aesthetics. The average cost of metal-plastic crowns starts from five thousand rubles.

However, combined crowns have a number of disadvantages that are definitely worth considering:

• The plastic finish of crowns very quickly loses its visual appeal; it may turn gray or yellow. Plastic tends to absorb moisture from the external environment and therefore the plastic layer swells and an unpleasant aroma begins to emanate from it;
• Combined crowns do not have high strength indicators; they can break due to excessive loads; most often, during the chewing process, it is the finishing plastic lining that falls off.

Plastic has fairly low biocompatibility rates, so metal-plastic crowns are not recommended for installation by people prone to allergic reactions.

What dentures are best for the front teeth?

Since the teeth in the smile area are visible to others, high aesthetic demands are placed on prosthetics in this area. In this regard, it is better to install prostheses made of zirconium dioxide (aluminum oxide), metal ceramics or all-ceramic crowns on the front teeth.

Caps made of solid ceramics are put on the upper incisors; they look good and are not subject to heavy loads. Products are made from medical porcelain using injection molding.

The lower incisors and canines bear a significant load, so in this case, solid ceramics are replaced with zirconium dioxide. The durable frame is coated with a ceramic layer to create a reliable and attractive prosthesis for the front teeth.

In addition, zirconium dioxide is successfully used when installing dental bridges in the smile area.

Metal-ceramic crowns for front teeth

The basis for this design is a metal base with a thickness of 0.5 millimeters. To obtain the material for such prostheses, a combination of chromium and cobalt is used, but sometimes you can find products made from precious alloys. In laboratory conditions, to create such crowns, they resort to the method of layer-by-layer application of ceramic material onto a metal frame. To ensure maximum strength and solidity of the structure, the ceramic mass is fired under high temperature conditions.

An aesthetic disadvantage of the above orthopedic products is the presence of a metal base under the ceramic layer. Moreover, the porcelain material used must be opaque to eliminate the possibility of it showing through the metal.

However, the light transmittance of dentin and enamel should be taken into account, which makes the outermost part of the tooth transparent in bright light. This indicates the inadmissibility of installing metal-ceramic structures for people with increased enamel transparency. The best option for using such crowns would be for patients with low levels of transparency. But it must be borne in mind that in strong lighting, differences in shade and light transmission may still be visible.

So, crowns for the front teeth made of metal-ceramics, as evidenced by reviews, have the following positive characteristics:

• Acceptable aesthetic indicators;
• Affordable price;
• High structural strength.

The disadvantages of such structures include:

• Negative effects on natural teeth;
• The likelihood of allergic reactions to metal material;
• Risk of cyanosis near the gingival margin.

Metal-ceramic crown »

Ceramic crowns for front teeth

These metal-free crowns for the front teeth are considered indispensable when restoring teeth in the frontal area. They allow you to eliminate some of the aesthetic shortcomings of natural enamel, which include excessive abrasion, developmental pathologies and massive surface damage. In addition, all-ceramic designs are ideal for individuals with a high likelihood of allergic reactions to metal alloys. However, they are not installed in the area of ​​chewing teeth, due to their increased fragility.

The ideal option is to fix such crowns within 1-2 lost units. Bridge crowns made of this material are not installed on the front teeth.

However, today, due to the active use of innovative technologies, you can find dentures made of ultra-strong ceramic material, suitable for recreating any lost tooth. Unfortunately, the cost of such a design will exceed the prices for classic products made from solid ceramics.

So, the “advantages” of the products presented above include:

• Impeccable aesthetic indicators;
• Full compatibility with the human body;
• Absolute identity with natural analogues.

Among the disadvantages of metal-free structures are:

• Insufficient strength;
• Overpriced.

Zirconium crowns for front teeth

Zirconium crowns for the front teeth are among the most durable and aesthetically perfect modern designs. Due to the use of zirconium material in their manufacture, it is possible to achieve high reliability indicators characteristic of metal and obtain prostheses with good hypoallergenic qualities.

Ceramic crowns for the front teeth, made on the basis of this material, do not have a metal base, which provides excellent aesthetic parameters. But their main advantage is still increased strength.

It should be noted that, despite the positive characteristics presented, some patients express dissatisfaction with the installed zirconium crowns. This is due, first of all, to the rather low light transmittance. That is, the difference between the transparency of natural enamel and the prosthesis material can also be traced here.

This means that it is better to install these designs in patients with slight transparency of natural enamel, which will provide a completely harmonious aesthetic effect.

However, at the present stage of development of dentistry, there is an improvement in the properties of zirconium crowns. Many manufacturers have taken a course towards creating blocks with higher levels of transparency and pre-painted products with a gradient. This made it possible to develop orthopedic structures that are completely identical to natural teeth.

Thus, zirconium dioxide prostheses are famous for the following advantages:

• Acceptable aesthetics;
• Increased reliability indicators.

The disadvantages of such products include:

• Lack of transparency corresponding to natural enamel;
• Zirconium crowns for front teeth are overpriced.

Zirconium crowns »

Ceramics on a zirconium frame

If you are interested in the question: “Which crowns are best to put on the upper front teeth?”, this option is certainly a winner. Such prostheses are ideal for those patients who dream of ultra-strong structures with excellent aesthetic parameters.

Unlike metal-ceramic prostheses with low aesthetic properties, zirconium-based crowns combine high aesthetic properties and the necessary strength.

Such crowns for the front teeth made of zirconium, as confirmed by reviews, are used not only in the process of single prosthetics, but are also excellent for the manufacture of bridge structures. At the same time, increased strength is achieved through the use of computerized technologies and milling methods.

So, some of the positive aspects when using these products include:

• Ideal aesthetics;
• Excellent reliability indicators.

Negative sides:

• Overcharge.

What is better to put on chewing teeth?

Since the chewing teeth bear the bulk of the load, the crowns on them must be strong. Most often, metal-ceramic crowns are placed in the lateral sections. Metal ceramics are durable and aesthetic, but require significant grinding of dental tissue.

Zirconium dioxide has proven itself to be excellent. Its strength is comparable to the strength of metal crowns; only zirconium prostheses, unlike metal ones, are very similar to natural teeth. Another advantage of this choice is the insignificant grinding of tooth enamel before prosthetics.

All-metal crowns on teeth are cheaper. They have a long service life and are resistant to corrosion. An even more significant disadvantage of such prostheses (in addition to the low level of aesthetics) is the risk of developing an allergy to the material.

Indications for prosthetics

• Chipped crown (when the defect cannot be corrected by installing a filling);
• multiple cracks in the enamel;
• pathological abrasion of enamel;
• fluorosis;
• tetracycline teeth;
• color change (darkening, yellowing);
• destruction of the supragingival part of the tooth more than 70% with preservation of the root;
• thin, weakened enamel;
• replacement of an old restoration.

Duration of operation of different types of crowns

The most short-lived structures are made of metal-plastic. Therefore, they are traditionally used as temporary crowns. The maximum service life of products is 5 years. According to patient reviews, over time the plastic coating deforms and darkens.

Metal-ceramics is a practical option that is installed on both the front and chewing teeth. Such structures last up to 10 years.

Crowns made of medical porcelain do not darken or fade and can last up to 10-15 years. Throughout this period, the product looks like a natural tooth.

Crowns made of zirconium dioxide are considered even more stable: their service life is 15-20 years.

Prostheses made from precious metal alloys and products made from nickel are also durable and can last up to 15 years.

The service life of different types of crowns depends not only on the material, but also on the accuracy of installation. There should be no voids or gaps under a well-fixed crown. Otherwise, food debris will accumulate under the product, which over time will lead to the development of an inflammatory prosthesis.

Main types of metal-free structures

Metal-free crowns do not have a metal frame and can be made from the following materials:

1. Porcelain. Porcelain crowns are made by firing and subsequent glazing. This method allows you to obtain a fairly durable and at the same time aesthetic denture.
2. Zirconium dioxide. The most popular material today. Like cermets, zirconia serves as a framework onto which the ceramics are applied. Only the latter material has a natural white color and does not change the shade of the artificial tooth, unlike dark metal.

It is worth noting that metal-free prostheses are manufactured using modern CAM/CAD technology. This technique is considered the most advanced today and allows you to achieve outstanding accuracy of the finished crown. After the doctor takes impressions of the jaws, they are transferred to a computer, which cuts out the frame from a zirconium dioxide blank with maximum precision. A crown made in this way does not require further adjustment and grinding after installation.

In general, metal-free crowns can be considered the most modern, aesthetic and expensive.

How to properly care for crowns

The method of caring for crowns is practically no different from the principles of caring for natural teeth and involves:

• performing oral hygiene twice a day (not only the teeth, but also the tongue should be brushed);
• cleaning the spaces between teeth and the space under dentures. To ensure the proper level of hygiene, it is preferable to use an irrigator: a directed jet helps to quickly and painlessly clean the space under the product;
• nutrition correction - excluding too hard foods and temperature changes from the menu;
• monitoring the condition of the gums and areas where teeth meet crowns (this is where caries most often develops);
• using mouth rinses after each meal (special formulations can be replaced with plain water).

Dentists also advise periodically massaging the gums under the structure. Soft tissues undergo increased pressure, so it is important to stimulate blood circulation in these areas. The gums should be massaged with smooth circular movements clockwise and counterclockwise.

Service life of dental crowns, crown warranty

The normal lifespan of dental crowns is about 8-10 years. A prerequisite for such a long service life is the quality of the therapeutic preparation of the tooth (the quality of root canal filling), as well as the accuracy of the manufacturing of the crown. Precision should be understood, first of all, as the exact fit of the crown to the neck of the tooth, which is ensured by correct preparation of the tooth for the crown, taking an accurate impression, and good work of the dental technician (24stoma.ru).

According to statistics, in 60-70% of cases, root canals are filled poorly, which leads to inflammatory complications, the need to re-treat the tooth and even remove it. Moreover, most often chronic inflammation manifests itself just after the end of the warranty period, i.e. after 1 year. For comparison, in Germany the guarantee for prosthetics is on average 3-5 years. In addition, the service life of crowns is also affected by the level of oral hygiene of patients after prosthetics.

How much does it cost to install a crown on a tooth?

The key criterion that determines the cost of prosthetics is the material used to make the prosthesis. If you arrange them from cheapest to most expensive, the list will look like this:

• metal-plastic;
• metal;
• gold;
• metal ceramics with ordinary metals;
• metal ceramics on a gold base;
• ceramics;
• zirconium dioxide.

In addition to the material, the price of the prosthesis is also influenced by the pricing policy of the clinic, the equipment used, and the qualifications of the attending physician. Some clinics manage to save money on prosthetics by installing crowns on several teeth at once.

It is impossible to accurately answer the question of which crown is best to install. The doctor makes the decision together with the patient. When choosing, emphasis is placed on clinical indications, characteristics of the patient’s jaw system, the state of oral health in general, the wishes and financial capabilities of the person.

Stages of prosthetics

1. Preparation
   - assess the general condition of the oral cavity, take an x-ray, carry out hygienic cleaning (removal of plaque, tartar), treat caries, gums, change old fillings.
2. Preparation
   - the front tooth is ground down for a crown, the stump is given the desired shape. According to indications, depulpation, treatment, and filling of dental canals are carried out. In case of severe destruction of the supragingival part, the root is strengthened with a stump insert. The prepared support is covered with a temporary plastic structure to protect tissues from destruction, chemical and temperature irritants.
3. Taking impressions
   – the doctor takes impressions of the patient’s teeth using an impression tray with impression material or a digital scanner. The obtained data is transmitted to the dental laboratory.
4. Making a crown
   - based on models, an orthopedic system is created in the laboratory using casting, pressing, and milling. At the manufacturing stage, the model is tried on the patient, and adjustments are made if necessary.
5. Installation
   - the finished crown is fixed to the support with dental cement. The crown on the front tooth implant is installed using a cement or screw method.

Alternatives to a Dental Crown

Veneers are often preferred to crowns in the smile area. However, in this case, the back side of the elements should be more or less preserved.

Teeth can be restored using filling materials. This method can only be used if the destruction of the unit is not so global (less than half).

Judging by the reviews of doctors and patients, crowns are considered the optimal solution for significant damage to teeth, since they not only restore the functionality and aesthetics of a row, but also protect teeth from further destruction. An additional bonus of this type of prosthetics is the variability of materials and, accordingly, the cost of services.

Glass-ceramic crowns E-max

Glass-ceramic crowns are an excellent option for those who want to get the most aesthetic results from prosthetics. The cost of one E-max crown is from twenty thousand rubles.

Despite all the advantages, glass-ceramic crowns have one significant disadvantage: they are applicable only in the case of single defects in the dentition. A bridge can also be made from glass-ceramics, but with no more than three crowns, and it is fixed in the area of ​​the front teeth. These limitations are associated with the strength of glass ceramics, which will be insufficient for a massive bridge, which will also be subject to significant load (during the restoration of chewing units).

Single glass-ceramic crowns can be used for prosthetics of any teeth - front and chewing. Such crowns can be monolithic or two-layer; any type of product is produced using computer modeling technology.

Prices for tooth crowns at Elident

When assessing dental crowns from the standpoint of which ones are better financially, one should take into account the material used, the technological solutions being implemented, the equipment used, as well as the level of professionalism of the specialist and the rating of the dental institution in which the teeth are restored.

The Elident clinic has affordable prices for all types of services related to the fixation of implants and the installation of dental crowns. At the same time, you can always count on an individual attitude and high professional training of dentists, which is combined with the use of highly effective innovative equipment and modern prosthetic concepts.

Factors in determining the price of prosthetic crowns

Even for crowns made from the same material, produced using the same technology, prices in different dentistry can vary greatly. This is explained by the fact that when determining the price of a crown, the following factors are taken into account: The pricing policy of a particular clinic. Different dentists focus on different consumer audiences. Therefore, prices may vary. For example, in some dentistry, the price of zirconium crowns will be 25,000 rubles, but you can also find offers with a lower cost - from fifteen thousand rubles; Experience, level of qualification of the doctor who will conduct orthopedic treatment; The work of a dental technician directly involved in the manufacture of crowns. The crown production technology can also be mentioned here; Cost of crown production material; Equipment of the medical facility. If the clinic does not have its own laboratory for the production of dentures and crowns, it will be forced to turn to the services of a third-party organization and, naturally, will include its costs in the price of the crown.

Equipment of the medical facility. If the clinic does not have its own laboratory for the production of dentures and crowns, it will be forced to turn to the services of a third-party organization and, naturally, will include its costs in the price of the crown.

Of course, any person faced with the need to get a crown wants to save on the service and at the same time receive high-quality treatment. It is possible to save on prosthetics with crowns, but the approach to saving must be competent. For example, you can install a combined bridge with crowns made of different materials or opt for metal crowns if we are talking about prosthetic teeth while talking and smiling that remain invisible to others.

But we categorically do not recommend you to chase low prices for dental crowns. Most often, the low price of crowns is not explained by a profitable promotion from the clinic, but by the low quality of materials and the work of inexperienced doctors and technicians. Such a crown will not last long, which means you will have new visits to the dentist and, accordingly, new expenses.

Comparative characteristics of the best crowns

To determine which crowns are the best , you need to study the pros and cons of each product, taking into account the material used.

Next, we will compare the key parameters of various prosthetic options:
