Cladding ceramics of teeth. How to whiten ceramic teeth and care for them at home: cleaning of metal-ceramic crowns. How much is a ceramic crown

What is ceramic crowns

A crown of special dental ceramics, like any other crown, is a way to hide the resulting defect and restore the natural function in the destruction or absence of one or more teeth.

Ceramics is a substance of a heterogeneous structure: on the one hand, it can be considered as glass, and on the other - as a crystal, and, combining it with others chemical elements, got several types of ceramics with special properties, Including the one that is used now in orthopedic dentistry.

A little later, it was possible to create high-tech ceramics, which was first used in the space industry, and for many years later he swallowed in dentists' cabinets - ceramics based on zirconium oxide (dioxide). Prior to its appearance to the use of measureless ceramic crowns there was only the correction of the front teeth - cutters and fangs - in people with increased sensitivity To various metals and their alloys, and almost never ceramics were used to restore the function of chewing teeth. But ceramic crowns from zirconium oxide allowed to solve this task.

Contraindications will be bruxism - grinds teeth in a dream.

Types of ceramic crowns

1. Veneers. They are ceramic lining (inserts) on the teeth. They are glued on outer surfacelocated in the smile zone. It is done to improve their appearance or close a large intersuban gap. It should be said that these plates can be made from another composite material, but in any case they will need a shallow entry of enamel before their installation, and this process is irreversible. Therefore, think before you decide on it.
2. Tabs.Dental prostheses of small sizes that serve to restore only a small area of \u200b\u200bthe damaged tooth. This can happen, for example, if the tooth is destroyed by only one third. Ceramic tabs have high strength, their structure is much more dense, in contrast to the usual sealing material; They will not contain micropores, which allow not to develop caries re-, and do not sit down. They are made in a dental laboratory from casts, which are pre-done in the doctor's office, and fix on the teeth with special glue. It is necessary to understand: use the tab instead of the crown only if there is a solid base of the tooth.
3. Actually, ceramic crowns.

Advantages and disadvantages

Pros:

• They have very high biological compatibility with the human body (they do not provide negative influence On the tissue of the oral cavity and do not cause allergic reactions).
• Possess the same light and light engineering as natural teeth (light rays evenly pass through all the crown layers, without meeting the obstacles on their way - a metal cap, for example, which is present in crowns from metal ceramics; thereby achieved more high level Aesthetics of restoration).
• Perfectly suitable for bridge prosthetics (when the adjacent teeth, located on both sides, are used for both sides), and for cementing on the titanium pin with implantation.
• They have a perfectly smooth surface (less than a raid).
• It is precisely adjacent to the cult of the tooth and not sitting down (thereby decreases the possibility of the occurrence of secondary caries).
• They are light.
• Not subject to various dyes.
• Do not create metal Tribus in the mouth.
• Eliminate the ability to expose metal over the gum and subsequent correction of the crown.
• Allow you to forget about such by-effectlike the sinusiness of the gums (when metal due to oxidative reactions Coloring edible gums).
• Do not allow the gum into the crown (due to the lack of an addecessar location of the ledge).

Minuses:

• Ceramic crowns have low strength (it was for this reason that the prosthetics of teeth with ceramics until recently was not widely distributed, especially for the first generations of ceramic materials).
• They are fragile.
• Prone to cracks.
• Influence the teeth-antagonists (located on the opposite side of the jaw), leading to their excessive erasure.
• Complicated in repair in the event of a breakdown of the structure.
• Briefly.
• Ceramic dentistry restoration is much more expensive than metal ceramics.

Manufacture

At this time, four technologies for the manufacture of artificial ceramic teeth are most famous:

1. Firing on a refractory model or on platinum foil;
2. Casting frames with subsequent cladding;
3. Pressing (technology " Empress."And" e.Max»);
4. Milling of the ceramic block on a computer program (CAD / CAM technology).

Burning

For the first time it began to apply for porcelain cladding. For this, in the first years of use of the method, the ceramic mass of speckled in vacuum on platinum foil, and a special refractory model began to be used much for this, which could withstand high temperatures Due to the inclusion of phosphate compounds in them, and this has made it noticeably to reduce the process.

According to this technology, very accurate structures have created at relatively low time spent, and then having learned to add various chemical compounds (These were insoluble oxides), achieved the impeccable similarity of the prosthesis with a natural tooth.

Casting

The principle of this method is the same as used in the production of kitchen heat-resistant ceramic dishes. The crown casting is made by centrifuging to refractory forms. But, unlike the firing, such a crown almost does not have micropores, and it is easier to polish, making combination with a tooth more natural.

Unfortunately, this technology does not allow making one-piece bridges, and it is also very complex, so it has not received such widespread as the following two.

Pressing

It was a real revolution in the field of prosthetics without ceramics. One of the first in the dental market was presented with IPS Empress company of the company IVOCLAR, with which the defects of the crowns of all teeth groups could be restored, taking into account the individual selection of color. Empress - pressed ceramic material, prostheses from which has a number of obvious advantages:

• good strength (compared to the firing on the model and the casting method);
• perfect aesthetics;
• high accuracy of fitting to solid tissues of a restored tooth;
• wire resistance, similar to the solid tissue of teeth.

The advantage of this technology was also in the fact that during the formation of ceramics accurately reproduces all the parts of the wax composition, even the thinnest edges, which ensures the edible fit with an accuracy of up to 20 microns. In addition, this material can be contlected several times.

Ceramic dental prosthetics without the use of metals by hot pressing can be both frameless and created on the basis of a frame, for example, all the same zirconium dioxide. Of course, at the request of the patient, ceramic mass can be pressing on a metal frame, but then the tooth will lose its optical advantages (light absorption and tooth light change).

How do ceramic teeth make?

Stages of prosthetics with ceramic crowns using technologyEmpress:

1. Consultation of the doctor before prosthetics: it turns out the cost of the work, the timing of execution is negotiated, etc.
2. Preparation oral cavity: Supported teeth are treated if it is required, and then slightly roll up.
3. Created dental surface.
4. In the cast in the laboratory, the wax model of the future crown is painted.
5. Using this model, the ceramic mass is heated to 1150 ° and pressed under pressure in the form, why the crystals adjacent to each other much more densely than in conventional sintering; The design becomes more stronger.
6. Then it is burned and adjusted by applying several additional layers of ceramics.
7. Next is the installation of ceramic teeth: in the doctor's office, the crown doctor, if necessary, is corrected and fixed to cementing glue, having the same optical characteristics as the structure of the prosthesis.

But the development process did not stop at this, and the developers of the same company were invented by another type of pressing, but already with the addition of dysilicate of lithium or a familiar zirconium dioxide. This method was given the name " IPS.e.max", And within this name there are several other addictions (depending on the fact that the substance is included in the structure of ceramics and how the crowns are simulated).

Stages of dental prosthetics with pressed ceramic crowns using technology "E.max ":

They are similar to the method that is described slightly above. The only difference is that in the laboratory in the ceramic mass for strength, a lithium salt or ceramic mass is poured into a predetermined frame of zirconium oxide. Adding these compounds even in small percentage ratios allowed us to increase the mechanical strength of all-tempered crowns. Their strength becomes comparable with metal strength.

Milling

The idea of \u200b\u200bcomputer reconstruction arose more than 30 years ago in Switzerland. The essence of computer technology for the manufacture of artificial ceramic teeth is to obtain a scanned copy with a special video camera with a removal tooth. The computer, processing information from the camcorder, displays the virtual model on the monitor and forms a prosthesis on it. The doctor plans the form of a future design, determines its parameters, and then a computer-driven grinding unit milling it from a ceramic blank.

This method is the most accurate when creating artificial dentures of any type.

How to care

Hygienic care for ceramic prostheses is no different from the peculiarities of hygiene for natural teeth. It is also necessary to brush the teeth at least two times a day, try not to prequite too tough food by the part of the jaw, where the crown or tab is installed, as well as thoroughly cleaned the interdigible spaces with special dental threads - floss.

With proper oral hygiene, you significantly increase the service life of dentures from ceramics.

Life time

Ceramic crown on the tooth is short-lived; The term of its use does not exceed 5-7 years, but there are cases when the crown has served as to patients for 10 years and more. And since the ceramic crowns prosthet the front teeth, experiencing the smallest chewing load, the probability of their breakage is significantly lower.

Question: Does the tooth depugt or not under ceramic crowns?

Answer: No, nerves are not opened and not deleted.

Question: How strongly do the tooth when installing a ceramic crown?

Answer: With a non-remote prosthetics, the doctor rolls less than a metal-ceramic or other design would be used.

Question: How do the temperature differences on ceramic crowns affect?

Answer: Ceramics as a material has a low thermal conductivity, so they are not terrible to her.

Question: Can I use ceramic teeth for removable prostheses?

Answer: Yes, they can be used in removable prosthetics.

Question: Can the smell of mouth appear after installing the ceramic crown?

Answer: Ceramic crown has no smell; The reasons for its appearance can be somewhat, and in any case it is necessary to consult with the dentist.

Question: What if the ceramic tooth broke off?

Answer: In this case, the restoration of the entire ceramic crown is required.

Domestic ceramics - these are ceramic crowns that belong to a relatively new method prosthetics of teeth, mainly used to hide aesthetic defects. Caries and other dental diseases are not only pushing the tooth from the inside, but also affect its appearance. Enamel fabrics darken, weakening and are destroyed. If one of the teeth "smile zone" suffered, then best way It will be the creation of a prosthesis that completely repeats the original view of the lost part of the tooth.

In this case, ceramic crowns become needed. Ceramic crown on the tooth Allows you to solve this problem. Domestic ceramics suitable for this best: its texture best matches natural. In addition, the finished crown can be painted in any color. Prosthetics of measureless ceramics Provides the preservation of not only the aesthetic properties of the tooth, but also function indicators. - This is the optimal view of the modern restoration of destroyed or lost teeth in the frontal jaw.

Ceramic crowns during prosthetics of teeth will be suitable not only to those who want to restore visible part teeth, but also patients suffering from allergic reactions to metals. Domestic ceramics - It is hypoallergenic material, the most naturally felt in the mouth. It also does not affect the taste of food, does not irritate the gums and does not oxidize. Until recently, ceramic crowns used only for "external prosthetics. This provision corresponded to the information in Internet search engines on request: ceramic crowns on the front teeth reviews.

Ceramic crowns To the tooth and on the implant of their price in Moscow. Ceramic crowns or metal ceramics What is better than their advantages and disadvantages?

However, ceramic crowns based on zirconia dioxide allow you to put crowns from ceramics and on chewing teeth. In this regard, non-free ceramics can now complete for prosthetics of all teeth groups. Patients sensitive to alloys have the opportunity to fully restore the chewing function, because, by strength and tolerance, the temperature drops of the ceramic crown on the framework of zirconium dioxide is not inferior to metals.

About, what advantages and disadvantages have ceramic crowns Or non-free ceramics, we will tell you in subsequent information. It is not worth tightening with the restoration of the tooth: prosthetics in the early stages will cost much cheaper and protect the tissue from re-destruction. We will pick up for your individual case The rational version of the prosthetics of teeth at an optimal price.

Ceramic crowns - advantages

Dent row recovered by crowns from non-velocular ceramics

• Maximum compatibility With a human body: ceramics does not cause allergic reactions, does not oxidize, does not "darken" the gums even during long wear.
• Ceramic crowns on the front teeth It is impossible to distinguish from natural teeth. The structure of the material corresponds to natural in density and light-based. Even in bright sunlight Your smile will look as natural as possible.
• Prostheses are made on casts with maximum accuracy. They adjacent to the preserved part of the tooth and not "sit down" after long-term operation. The formation of the slit and the re-infection of the tooth is excluded.
• Ceramic dental crowns Different with ease and security. They do not press the neighboring teeth and do not overload the gums. This property allows them to be used to install "bridges" or cementing on the titanium pin.
• A smooth, self-cleaning surface is not painted, does not absorb smells and does not darken over time, and also does not accumulate the dental flare.
• Moting prosthetics Safe for soft tissue oral cavity. The edge of the gum is not injured about the gums of the ledge and does not occur in the gum.
• When requesting: " ceramic crowns on the front teeth reviews»You can get positive information about the aesthetic side of prosthetics with such crowns.

Domestic ceramics - Disadvantages

• The most aesthetic types of ceramics are different fragility: The prosthesis can be writing from strong hitlike a real tooth. The problem is solved by the preferences of zirconium or extruded ceramics.
• Cost of ceramic teeth somewhat higher than the cost of metal-ceramic crowns.
• The crown material does not affect the adjacent teeth, but can lead to premature erasing of the antagonist tooth.
• With the appearance of chips As a result, the mechanical strike is easier to replace the entire design than to restore the affected crown.

What crowns are better to install on the front teeth and on the rear teeth?

The methods of prosthetics of the front teeth and molars differ due to the fact that these teeth perform different functions. When eating food, the main load accounts for chewing teeth, respectively, strength and resistance to temperature differences are key factors. But when restoration of the smile zone is greater importance natural view Tooth, therefore it is more expedient to select the most lightweight and "naturalistic" material. In this case, it is advisable to apply ceramic crowns.

For restoration of the rear teeth It is better to use ceramic or metal-ceramic crowns based on the remaining cult. They can cover pretty large area tooth and take the load on chewing, not risking to crack or break. For this type of crown, extruded ceramics of increased strength or zirconium are used. Zirconia crowns and veneers are the most modern view Tooth prosthetics.

When prosthetizing the side departments of the jaw crowns from zirconium dioxide is a rational choice. Crowns from zirconium dioxide in our partner clinics stand from 17 000 ₽. When considering the price of crowns from zirconium dioxide, you will see that on request: a crown from zirconia price Moscow "Our price will be minimal.

If you need to restore a small area front tooththen it is advisable to use viniron. These mini-prostheses are able to disguise the small chip even the most unusual form so that no one will notice changes in the structure of the tooth. Zirconium dioxide veneers are the most rational version of the aesthetic restoration of the tooth in such cases. If the lesion of natural tissues reaches 20-50%, then a full-fledged coron Corridgeperformed in accordance with external species Damaged tooth.

Indications and Contraindications for Test Prosthetics

Replacing teeth on ceramics (full or partial prosthetics) It can be carried out with almost any forms of destruction of teeth. In short: if you are offered to put a crown, then you can safely choose ceramics. There are no specific contraindications of this material. But there are the same limitations as for conventional prosthetics.

It is carried out in the following cases:

• Destruction of a tooth as a result of injury or progressive caries.
• Development anomalies that cannot be adjusted by an orthodontic method.
• Notable aesthetic defects Crowns of "native" tooth (for example, a sharp darkening).

And not held in the following cases:

• The pulp is too close to the surface (for example, in children and young people until 20-22 years old).
• The patient suffers from periodontitis in severe form. The crown can aggravate the condition of neighboring teeth.

Price of a ceramic crown tooth in Moscow

Ceramic crowns in clinics Partnership "Dentaland" stand 17 000 ₽That includes the cost of preparing the surface of the tooth when non-free ceramics are selected. When considering the orthopedic product - ceramic crowns or domestic ceramics It must be understood that cost There are not only such crowns from the value of the material (although it is an important pricing factor). The complexity of the case as the technologies that will have to be used are also taken into account. Ceramic crowns whose cost is lower than the average prices in Moscow - This is a non-free ceramics offered in our partner clinics.

We do not need an action entitled: Ceramic crowns - cheap or non-free ceramics with a discount. It is in the Clinics of Partnership "Dentalond" is offered for the dental prosthetics ceramic crown, the price of which is minimal by rating in Moscow. When requesting B. search engine Yandex "Ceramic crown to Tooth price Moscow» You will see how much is a ceramic crown on the tooth In various clinics of Moscow. In our clinics, a ceramic crown to the tooth, the price of which is 17 000 ₽ - this best price To position: Domestic ceramics on the front teeth or ceramic crowns on the front teeth.

We consider it important to note that if when requesting: " ceramic Crown on Tooth Price Moscow»You will read that a ceramic crown on the tooth is offered, the price of which is fair to our price or lower, then try to find out what is not included in their understanding of the phrase" ceramic crown tooth price ". In most cases, you will need to even pay extra for various manipulations during prosthetics with these crowns. Then you will realize that the price of ceramic crowns will be different.

In our suggestion with the phrase ceramic crowns on the front teeth Or non-free ceramics indicates the price, including all manipulations in the manufacture of such crowns. If we write on our website: a ceramic crown to the tooth, the price of which is 17,000 ₽, then there will no longer be any additional payment.

Price of ceramic crown on implant in Moscow

Ceramic crowns on implants in Moscow also have a different price in a number of dental clinics. We want to note that ceramic crowns on implants in Dentalland partnership clinics are worth from 25 000 ₽ to 30 000 ₽. The price of crowns on implants is indicated in this interval due to the fact that they are applied different kinds implants. It is necessary to understand that ceramic crowns on implants or metal-ceramic crowns on implants can be made. Naturally, that ceramic crowns and metal ceramic crowns Will cost differently.

Due to the fact that the price of these types of crowns is different, the question often arises: ceramic crowns or metal-ceramic, what's better? Each type of orthopedic data has its pros and cons. It is necessary to consider this question comprehensively, but it is precisely what load on the crown is assumed, there is or not allergic to metals, the tab or tooth is under the crown and in which the jaw department is supposed to prosthet the teeth.

With this approach to the selection of the crown and the answer to the question: ceramic crowns or metal-ceramic, which is better, will be reasonable. Domestic ceramics has advantages and disadvantages.

Types of ceramic crowns

• Coronels of pressed ceramics. Such prostheses are widely used to restore the front teeth. Their natural look and similarity with natural tissues on reflective properties allow you to achieve the most naturalistic impression. These ceramics-based crowns can also be used to prosthetize chewing teeth (in cases where it is especially important to maintain the aesthetic characteristics of the tooth).
• Zirconium-based prostheses. Formally rather relate to metallic, but on price characteristics and properties are more reminded extremely solid ceramics. Used to restore molars, as they can withstand almost any load. The limited color row is quite suitable for the invisible prosthetics of the rear teeth, but in the smile zone, such a crown will be too highlighted.

Stages of manufacturing ceramic crowns

• The tooth is treated, purified and prepared for removal of the cast. Supported teeth are fell under the future design.
• It is made of the shoulder of the jaw (or the jaw site with a damaged tooth).
• A wax prototype of the prosthesis is prepared in the dental laboratory.
• The specialist heats the ceramic mass and presses in the form under pressure. This ensures the maximum strength of the finished prosthesis and the more natural structure of the layers.
• After the formation, the model is carried out, then an additional ceramic spraying in several layers is applied from above.

Ceramic crowns from zirconium dioxide and E-MAX on the innovative technology "3Shape" (Denmark)

In the case when the patient wishes to spend the prosthetics of his teeth in compliance maximum indicators aesthetic perception and functional comfort, then technology is used, implying use zirconium dioxide and ceramics E MAX. At the same time, there is always a desire to eliminate the likelihood of erroneous actions as when removing implications from supporting teeth, and when modeling the ceramic crowns themselves. However, it is impossible to forget about the particular importance of a rational determination of the type of closure of dentitions, namely, about the definition of bite.

Of course, there is no need to remove the impression by noncomforty imputation masses and to suffer with the definition of bite as a result of fixing between the hemoplastic anthonist teeth. At the same time, despite the presence of pleasant and non-irritation of the mucous membrane in the oral cavity of the mouth of the mouth, the procedure of introducing an absorber spoon in the oral cavity and the human factor in the form of a doctor's ability to optimally carry out the indicated manipulations.

For the purpose of exception human factor And the need for the above procedure for removing the implications and the definition of bite was developed various systems of scanners, allowing these manipulation data as a result of use computer technology .

One of the modern newest computer scanning technologies in the oral cavity is a system developed by Danish scientists. This innovative program is called " 3shape».

During work with this a unique program It is possible to scan the surface of the teeth, jaws and type of bite to scan the surface of the teeth, the jaw and the type of bite with the subsequent transmission to the computer program that simulates the form of the desired crown and the feeding command for the manufacture of an outfoded design from zirconium dioxide or E max.

It should be noted that if as a result of scanning computer program Detects errors in the transmission of the tooth shape, then notification is notified on the computer screen. After that, it is necessary to correct the specified error and only after that the program will "allow" the 3D image to the computer system in the dental laboratory.

Thus, it can be confident that when using technology " 3shape"In the manufacture of ceramic crowns errors are excluded.

Installation: How do crowns hold on teeth?

One of advantages of ceramic prosthetics - No need to heat the tooth or attach a metal pin to the root. So that the crown is kept, it is enough to sharpen a few space for it (as a rule, no more than 1-2 mm). The finished prosthesis is attached to the tooth cult with a special cementing glue. This allows the crown to "stand up" to the tooth as accurately as possible without leaving the gap between natural and artificial material.

Glue reliably fastens the tooth: it does not change its properties at a temperature effect and does not respond to physical exercise or friction. The optical characteristics of the cementing substance fully correspond to the characteristics of the prosthesis, so the border of the connection cannot be found even with a microscope. This is especially important when prosthetizing the front teeth that are constant.

Strength and service life of zirconium dioxide crowns

Basic function ceramic prostheses - aesthetic. They are valued primarily for the ability to hide the prosthetics itself. A stranger will not be able to determine that you have a crown if you do not inform about it. Since prostheses are not felt in the mouth, do not require specific care and do not cause pain sensations, they are easy to forget about them. But ceramics is not metal: if you regularly use prosthetic front teeth for chewing, the crown can crack. Remember: "Smile Zone" is not intended for biting nature, and ceramic prosthetics of this fact does not cancel!

• Clean the prosthesis in the same way as for all other teeth. Do not too dilute and clean the prosthetized area longer than the "native" teeth.
• Brush your teeth at least twice a day: in the morning and evening.
• Try not to overbind too hard food with a prosthetic tooth. This is especially true of the front teeth.
• After receiving food or before cleaning the teeth, clean the intersubolic space of the hygienic thread.

Zirconium dioxide crowns are cheap - this is to us!

Protecting and strengthening destroyed teeth restoring their original shape.

The most common types: metal, and all-tempered. Machine from each other.

Ceramics, like material for prosthetics of teeth

Properties of ceramic material:

1. Biological inertness, the human body does not react to ceramics, as an alien body.
2. Lack of harmful substances.
3. Ceramics does not absorb foreign smells.
4. Does not react with pigments and bacteria.
5. Does not cause gum inflammation.
6. It has high strength.
7. Crowns from ceramics are very similar to natural teeth. They With high accuracy Mimic color, transparency, natural toothbrope structure.
8. Lack of metal frame in crowns. This makes them thinner of their fellow, which has a consequence in the form of minimal turning of the tooth.

Use of ceramics in dentistry

Ceramic crowns are dentures in the form of a ceramic cap, restoring the initial view of the crown part

Viniron from ceramics

destroyed tooth. The most expensive type of dental crowns. .

IN dental practice Ceramics are used in the manufacture of single crowns, removable structures, special inserts and lining, restoring part of the damaged tooth.

Ceramic prostheses are made from zirconium oxide and extruded ceramic mass. There are all-tempered (porcelain), prostheses with zirconium frame, lined with ceramic mass.

About the advantages and minuses seriously

Advantages Compared with other types of crowns:

1. Durability - Serve for at least 10 years, subject to medical recommendations. They do not crack, do not crumble, not painted with dyes, do not deform. Damage and chips are well restored.
2. Ease - Do not overload the support teeth when chewing.
3. Safety - does not adversely affect the body, it does not provoke the erasability of opposing teeth, there is practically no prostheses inflammatory processes. Do not oxidize, does not spoil the taste of food.
4. No allergic reactions - Unlike hypoallergic metals and does not give food to the taste of metal in the mouth.
5. Minimal injury of support teeth - Ceramic crowns are made very subtle and durable, so they are fixed on the support teeth with minimal feeding of the latter.
6. Aesthetics - This with difficulty is different from natural teeth due to the living gloss enamel and the ability to skip light.
7. Easy to care and no irritation In the oral cavity.

The minuses include:

1. Significant disadvantage of ceramic crowns can be considered fragility. In this they lose metal.
2. Small selection of materials. Only zirconium and porcelain are used. Of these, only zirconium suitable for the prosthetics of chewing teeth.
3. The disadvantage can be considered high cost ceramic structures.

Indication testimony

When allergic to metals, dental prosthetics in a smile zone, cases when the titanium implant is required to replace the crown, in order to avoid contact of different metals - it is recommended to install a ceramic crown.

Contraindications for prosthetics with ceramic structures:

• pregnancy condition;
• various inflammations in the mouth;
• chronic diseases;
• weakened state of the body;
• pronounced osteoporosis.

Before the procedure ...

To the installation of the crown tooth must be prepared. This includes a visual examination of the tooth by a doctor by orthodontist, direction on, treatment procedures and sealing channels, if necessary.

If the top of the tooth is absent completely, a metal dental is used for fixing the crown. The practice of installing pins today is outdated.

Installation step by step

Ceramic dental crowns are installed on the teeth in the same manner as others with small differences. This applies to a lesser degree of turning compared to from other materials and the ability to remove the nerve if the dental canals are healthy.

The rest of the installation procedure, the crown consists of removing the castors, the manufacture of the model from the gypsum, the selection of the color shade of ceramics (there is a special scale), creating a crown in the laboratory, fitting the prosthesis and install it to temporary cement, fixing the finished prosthesis to a pre-prepared tooth.

"Print" orthopedic designs with a special cement. It has long and reliably holds the prosthesis on the supporting tooth.

Upon completion of the prosthetics process, ceramics may appear painful sensationsIn such cases: with an incorrectly defined size of the design, the choice of the incorrect shape of the crown, if the edges of the prosthesis are poorly adjacent to the tissues.

Caring for crowns

To extend the service life of ceramic prostheses, it is necessary to install the usual hygienic procedures For the oral cavity: every day, do not bite hard foods, so as not to damage the crown and injure the reference tooth under the crown, do not use toothpaste with high abrasiveness.

Preventive examination of the teeth by the doctor is needed twice a year.

How manufactured

Motable ceramic crowns for dental prosthetics are manufactured in two ways: manual and computer. The choice of method depends on the technical equipment of the clinic and the laboratory and the type of material used:

1. Manual method It consists of the following steps: removing the cast of both jaws of the patient, the manufacture of collapsible gypsum model, modeling the future crown, pressing the frame of the crown, frame facing, glaze and grinding the resulting crown. In the final stage, the crown is processed by one of two techniques: for chewing teeth - surface staining, for the front teeth with a layering.
2. Computer method High-precision designs are created, almost without errors. This requires the presence of modern dental equipment that simulates the crown virtually. Schematically it looks like this: with the help of the oral scanner, a computer cast is created, special program Models the future view of the crown and sends information about it on milling equipment, which pulls the specified parameters from the blanks. The resulting crown can be finalized by dental technician manually if necessary.

Life time

The ceramic crown can serve from 5 to 10 years, depending on the patient's attitude towards it. After this period, it is recommended to replace it, to avoid the destruction of the tooth under the crown.

Asked - answer

Patients dental clinics are often interested in questions:

The photo clearly shows how the teeth look like after they were installed a ceramic crown

The cost bites

Prices for ceramic crowns are high enough. Everyone has it medical institution Its price and fluctuations in price are very significant.

In the capital of Russia, non-flowable ceramics can be put from 8990 rubles. Up to 46900 per crown. Ceramic crown will cost 12,000 rubles. up to 58900 rubles. But these are very exemplary figures.

Specifically, it is possible to find out the cost of a dental crown only for full-time consultation of the dentist's doctor.

In the dry residue

Any patient is a dental clinic that came there with a view to choosing that prefer. Undoubtedly, the first advice will be the attending physician. Good dentist always acts in the interests of the patient and enlightened about positive and negative moments in different ways Prosthetics will advise the best way.

What material to prefer for crowns the patient decides together with a doctor individually in each case.

To date, casting alloy-tempered crowns are leading in popularity, and made according to the method of ceramic spraying on the frame of the same material. For prosthetics of teeth, the smile zone is definitely the best option. It should also be remembered that good quality work It can not cheap cost and quickly go.

Today, the popular and reliable variants of prosthetics are often often attributed to a non-velocular ceramics. The main advantage of such structures is that they are made from very reliable, durable and aesthetically attractive raw materials.

How to make ceramic teeth

IN lately Dentistry is developing hard, therefore, ceramics without metal content are often used to create teeth dentures. This material is as similar as possible with natural enamel and differs from high-strength analogs. Ceramic crowns visually look at the real teeth, distinguish them almost unreal. These designs have a lot and other advantages:

• self-free products are well adjacent to the gums;
• they stand out for a long use and reliability;
• the ceramic crown does not cause an allergic reaction, irritation, biologically combined with the tissues of the oral cavity;
• do not need to sharpen strongly (dispense) teeth;
• the patient quickly gets used to crowns, because they are light and practically weightless, thanks to the material.

There are 4 main technologies for creating measureless prostheses:

1. Molding the frame and its cladding.
2. Firing on platinum foil or on a refractory model.
3. Milling of ceramic artificial teeth with computer technology.
4. Pressed design.

Types of crowns

There are several varieties of dental prostheses, they are classified depending on the material. Often in the dental clinic establishes a porcelain non-free ceramic crown or design on zirconium oxide. Both options are practically not different from the dentition, strong prostheses, reliable. To make it easier to decide - ceramics or zirconium crowns, Consider the types of ceramic structures in more detail.

All-tempered

If the prosthesis is completely porcelain or is made on the basis of another ceramic raw material, then this design refers to the all-tempered. Compared to metal-ceramic products, porcelain looks much more natural, naturally, can convey the color of the tooth tissue. The prosthesis of this type is installed on the front teeth or instead of chewing, which practically does not affect the service life. The all-ceramic crown fits tightly to the surface, it is very durable, does not change the color throughout the term of use.

On zirconia oxide

Ceramic crowns made from zirconium are ideal from aesthetic point of view. This material is a lightproof, so the enamel is as close as possible to natural color. In addition to this, zirconium products do not affect the toothbrope and the gums are negative. When using these crowns, there is no inflammation, recessions, the shade of teeth does not change. Allergic reactions either has not been noticed. Dentists talk about zirconium oxide, as about white gold in prosthetics.

Setting the crown

The procedure for the installation of dental nonetable structures consists of a number of stages that are very important and interconnected. Ceramic products "Mounted" in accordance with the following algorithm:

1. The first step is to consult a dentist. The doctor examines the patient, is a treatment regimen (if necessary), the installation of crowns.
2. Teeth must be prepared for prosthetics. For this, the dentist drills them, seals, treats caries, pulpitis, periodontalosis and similar problems.
3. The next stage is the preparation of teeth for nonmetric ceramics. Cracks do under local anesthesiaBecause the doctor removes a couple of millimeters of solid tissue.
4. Then there comes a turn of the removal of the cast by overlapping a special cement solution for the prepared portion. Focusing on the resulting cast, the prosthetist creates a gypsum model, and it makes a porcelain or zirconium design.
5. Ceramic crowns make in laboratory conditionsAnd then try the patient in order to accurately identify the right landing and how good they will adjust.
6. Sometimes a temporary installation of a measureless design is performed. This allows you to determine the tissue reaction on foreign body, closure, bite and other features of the oral cavity of a separate patient.
7. Final stage - fixation of ceramic prostheses. Finished structures are fixed on the cement basis. After their installation, it is not recommended to eat, drink for 2-3 hours so that the result is thoroughly fixed.

Lifetime Corona

Ceramic products are not installed for life. The approximate life of their operation on average ranges from 5 to 7 years. Under the condition of respect for the prosthesis, the construction service life increases to 10-14 years. Often such porcelain or zirconium products are fixed on the front teeth, which have a smaller load, so wear and break very rarely.

Price of ceramic crown tooth

How much is the nonmetric prosthesis in dental clinics? This question interests many. The cost of ceramics depends on several conditions.

An interesting story of the dental technology. In this form from the doctor, silicone prints of the patient's dental rows come after processing. At this stage, it is very important to estimate the quality of the cast, since the doctors pass unsuitable to the further use of prints. At this stage, we insert into Silicon (in the place where the teeth are processed by the doctor) special pins.
After that, the impression is filled with supergips and retention rings are inserted, with which the dental row and the base of the model will be interconnected.
When the super hypox freezes, the impression is poured over with the base plaster, which forms the basis of the model.
So the frozen model looks like, which is a copy of your jaw.
A spoon is separated. The model is processed along the edges.
Sheeps a stamp.
It is processed by cutter to a ledge. In this form, the stamp is suitable for the next stage.
The tooth cult is covered with varnish.
And rims into special wax.
The edges are removed. This is the prototype of the future crown.
The matrix is \u200b\u200bfilled with wax that will have the features of missing teeth.
Using the electric shift, wax crowns are charged with wax to the intermediate part obtained from the matrix.
Wax wrenches are attached to the resulting composition.
A spruce tree is formed and is charged to the bottom of the prime.
Overall is flooded with molding mass and freezes.
When the ooclee will freeze it, it is sent for 3 hours in 1000 degrees.
Then the molten metal is poured using the casting machine.
After separation from the layers, the casting is cut and processed by sand under pressure.
After you need to remove the remnants of the sprues.
And processed to the brilliance of carbide mills.
In such a form, the future prosthesis is ready to apply ceramics.
Before applying the layer (first layer), the frame is processed in the sandblasting machine.
And burns in the furnace with vacuum.
Then the tassel is applied denin (second layer).
The shape of the tooth is formed, chewing surfaces and burns again.
After the stove, the form is not ideal.
Therefore, we simulate the final form and again into the oven.
Here we bring ceramics with diamond builds to the final form.
In order for the teeth to glimpse, they are covered with icing and burn the last time.
Voila. Teeth are given to the doctor. With the help of dental cement, it lands the prosthesis in the mouth. At the same time, the doctor gets 50%, without carrying any expenses.
