Crowns zirconia. Price, service life, manufacturers, the pros and cons on the posterior teeth

Crowns zirconia - an innovative development in the field of dental prosthesis, which closes the tooth enamel destroyedOr else install a fully artificial molars. This structure is made of two main elements.

This metal frame and thin deposition layer of enamel porcelain. Price crowns zirconia varies depending on the material quality, denture products and the complexity of operation.

Components of dental products makes it durable and at the same time aesthetically appealing. The high quality of data bits due to the use of modern method for their manufacture.

Manufacture of dentures is preceded by the creation of three-dimensional model of the patient's jaw. Based on these data the electronic engineering model of the future denture, and then milling machine grinds zirconium metal skeleton from the workpiece.

Innovative approach to manufacture crowns based on zirconium dioxide eliminates the human factor, and prevents the occurrence of even small inaccuracies in the finished prosthesis. The next stage is creating a dental crown spraying tiny particles of enamel porcelain.

They are distributed evenly across the surface of the prosthesis. The finished product follows the shape of the jaw of the patient unit, closely adjacent to the gum, it does not cause tissue damage, discomfort and pain during wear.

Crowns zirconia dental possess the following properties:

• retain the aesthetic appeal of a smile, and a prosthesis mounted outwardly no different from a natural tooth;

  

• do not cause irritation of the mucous membranes of the oral cavity, it is hypoallergenic, which is very important for human organism which has an individual inclination to the manifestation of allergic reactions to products metal;
• is chemically neutral (aggressive environment of the oral cavity, the effect of acid, salt, fat, fried foods, fruit acids, does not cause oxidation or other change in the physicochemical characteristics prosthesis);
• crown formed of a thin metal layer, which minimizes the discomfort, reduces the period of habituation to the product and the period of adaptation of the jaw unit;
• spraying porcelain crown is wear-resistant, not darker or lightened for a long period of use;
• during manufacture crowns zirconia alloys are used which have a high density;
• malocclusion prevent premature wear of healthy teeth that are adjacent to or remote from the patient cutter;
• eliminate chronic infection, when there is a question of treatment of the patient with his teeth a further closing of the crown, made of high quality metal.

Crowns of zirconium alloy used in dental clinics all over the world. The positive properties of the product allow you to quickly resolve the issue of quality of dental prosthetics with the achievement of excellent aesthetic and long-lasting effect.

Composition

Crowns of zirconium dioxide are not two-component complex. Price of dental products formed by the manufacturer of dental prostheses, as well as the attending dentist as a result of the therapeutic process. The table below shows the detailed information about the features of chemical and physical composition of these crowns.

The composition of dental products	Chemical and physical characteristics of the constituent component
zirconium dioxide	This refractory metal with a silvery white hue. Zirconia has amphoteric properties. It is insoluble in water and most acids and alkali solutions. Wherein the metal oxide is capable of reacting with the HF and highly concentrated sulfuric acid. In dentistry industry and zirconia is used as the superhard material which has an increased density degree different service durability and does not undergo deformation during prolonged mechanical exposure. The demand in the field of metal dental prosthesis based on the fact that in the medical practice has not been a single case of allergy zirconia compound.
porcelain spraying	By applying porcelain spraying achieved aesthetic effect. Metal frame becomes an attractive appearance, and the artificial crown is indistinguishable from natural dentition. The attending dentist and prosthetic manufacturers perform the selection of the color tone of spraying so that the crown is made consistent with the natural color of the enamel healthy incisors. Furthermore, porcelain spraying performs the additional function of protecting the metal frame from the aggressive environment of the oral cavity. This component is prepared by heat treating a mixture of coarse plastic clay, kaolin, feldspar, quartz.

All component parts that are used during the manufacture of dental crowns based dioxide zirconium, are rigid laboratory testing and assessed for compliance with the stated standards quality.

Kinds

Varieties crowns based on zirconium dioxide are classified by the density of the metal strand, which is used in the milling process denture. This information shall be indicated by marking the framework of artificial teeth. In this regard, the following types of crowns zirconia.

High Strength Zirconіa 1,500 + -5OmPa

Dental articles of this kind are manufactured on the basis of zirconium dioxide with increased strength.

Used for prosthetic distal defects, when the dentition missing several cutters.

Also, the data bits are used to fix the height of the dental occlusion.

High Translucency Zirconia 100 + -5OmPa

This dental crowns, which are made of zirconia with 30% translucency. A dental article has high aesthetic appeal and smooth surface.

Crowns are used for the front rows of teeth prosthetics. Can be used to recover one or several cutters.

Full Contour Zirconіa 900> + - 100mPa

This type of dental crowns is actually already finished harvesting the prosthesis. After completion of the milling process is its bilateral staining using mikrobashey. Dyed head crown is finished workpiece technician on the basis of parameters of the patient's dentition. This type denture zirconia differs lowest density metal.

Life time

Crowns zirconia (price per dental product is determined by the product manufacturer) have antibacterial properties. This factor contributes to extending the life of dentures.

Crowns, which were made of high-tech material, installed in the dentition without disturbing the therapeutic Protocol remain an attractive aesthetic appearance, are not deformed, can withstand compression and mechanical loads during the 15-20 years.

Patients who have been set crowns based on zirconium dioxide, have to comply with the rules for prosthetic care. Wearing crowns should be careful, and daily oral hygiene and regular. The gaps between the prosthesis should be thoroughly cleaned from the remnants of food.

It is recommended to apply antiseptic solutions and rinses teeth. To extend the gloss and the aesthetic appeal of porcelain spraying, it is necessary to avoid the use of toothpastes, which include those containing abrasive additives.

Contraindications

Crowns zirconia (the price of the prosthesis depends on the quality and density of the metal) are safe solution restoration of decayed teeth.

Despite this use of dental products have the following contraindications:

• hypertonicity of the masticatory muscles and bruxism;
• chronic infections in the oral cavity tissues;
• presence of live pulp tooth enamel which is to be closed by means of the crown;
• malocclusion with a large overlap of the lower incisors;
• periodontitis, chronic or acute forms of flow;
• mental illness, associated with the violation of behavioral activity (dental procedures can trigger a stressful situation and cause a nervous breakdown);
• all types of tuberculosis;
• stomatitis, gingivitis and other inflammatory processes of the bacterial, viral or fungal etiology associated with impaired mucosal integrity and gingival tissues.

Dentist treats and conducts a preliminary examination of the patient's mouth. Upon detection of a number of contraindications to the prosthetic dental crowns using zirconia selects other therapies.

Side effects

Crowns of zirconium dioxide (the price of dental product starts from 15,000 rubles. 1 tooth) practically do not cause the occurrence of side effects. Negative reactions in the body are possible if the medical error was made, or the person is severely immunocompromised, suffering from inflammatory diseases of the oral cavity.

In the presence of these circumstances, the following side effects:

• redness and swelling of the gum tissue in the area of ​​installation of the prosthesis;
• pain while pressing the tooth crown closed;
• inflammation of the tooth pulp and the formation of purulent abscess (if the doctor did not fulfill quality dental tooth treatment);
• malocclusion (this side effect may occur if an error in the implementation of the dentition or crowns measurement was made);
• prolonged feeling of discomfort and the presence of a foreign object in the oral cavity;
• offset crowns and tooth violation anatomical location.

The above side effects are extremely rare. Antibacterial and anti-allergenic properties of zirconia, high density metal alloy, minimize attack these risks.

Advantages and disadvantages

Crowns zirconia - a kind of dental product, which has a minor imperfections and positive characteristics.

Advantages of this type of prostheses are in the following aspects:

• crowns zirconia set 1 time in 15-20 years, and some experts say that with proper care, they can last much longer;
• prosthesis edge tightly in contact with the gum surface, which eliminates the risk of infection at the tooth enamel surface with a defect (in this case eliminated the risk of secondary caries);
• quick and painless installation of the prosthesis, which does not require complicated dental procedures, surgery and anesthetic;
• antibacterial zirconia suppress the activity of pathogenic microflora;
• quality porcelain coating does not require particularly complicated care;
• based on the data bits can be fabricated prosthetic bridges with simultaneous replacement of 4 missing teeth (the metal structure maintains a high degree of strength with time and does not deformed);
• if necessary dental article can be installed on top of the implant;
• crowns of zirconia can be used to restore the destroyed dentition in people prone to the manifestation of acute allergic reactions;
• preserving the natural color of the surface of the crown, even after several years of operation.

The material from which the manufactured dentures, as well as ready-made dental products have minor disadvantages.

All of them do not concern the physical characteristics of the product, and the following aspects:

• the duration of the production process after fixing of crowns parameters dentition of the patient;
• the high cost of zirconia alloy and already finished denture (15000 rub. is the minimum price for 1 crown, which is not included in the work of the dentist performing the installation of the artificial tooth);
• manufacturing complexity, as well as a limited number of production centers capable of engaging e simulation jaw prosthesis and future with further milled metal stock dioxide zirconium.

Despite all of the above disadvantages associated with the production and use of zirconia crowns zirconium, more dental clinics are switching to the use of dentures on the basis of material.

Rating manufacturers

The main producers are the following companies crowns made of zirconium dioxide, which deliver high-quality dental products to the Russian and European market:

• Glidewell Europe - the company produces a crown for installation on 1-2 teeth, as well as dual-layer wide bridges, intended for dentition prosthesis to the lack of 4 or more incisors (average cost production of 15-20 thousand. rub.);
