What are the best dental veneers? Veneers for front teeth: what are they, which ones to choose

Ceramic veneers are microprostheses for restoring the shape of a tooth and changing its color. They provide a long-lasting aesthetic effect that no other whitening method can provide. Due to their unlimited shelf life and high strength, they outperform composite materials used for dental restoration. At the same time, they are installed without traumatic treatment of the teeth, which cannot be avoided when using prosthetics with crowns.

Features of the method and indications

Ceramic veneer (from the English veneer - to give an external shine, to mask) has the form of an overlay that replaces outer surface tooth (and sometimes lateral). Such a design can effectively and permanently solve a number of problems:

• unaesthetic color of teeth (yellowness, darkening);
• fluorous spots;
• abnormal tooth shape;
• chips on the enamel;
• too large interdental spaces.

Based on the materials used for manufacturing, they are distinguished:

1. Porcelain veneers made of pressed and unpressed ceramics. They have excellent aesthetics, adhere well to the teeth, but are not resistant to particularly heavy loads.
2. Zirconium dioxide overlays. They consist of a zirconium frame on which a ceramic mass is applied. The material is extremely strong (stronger than metal), but has low adhesive properties (i.e., they are not securely fixed to the teeth).

Based on the thickness, microprostheses are divided into:

• ordinary (their thickness is 1.3-1.5 mm);
• ultranir (from 0.3 to 0.5 mm).

The best manufacturers

Microprostheses made from ceramics from the following manufacturers are widely used in aesthetic dentistry:

• E-max (German lithium silicate glass ceramics of increased strength);
• Empress (very thin and durable reinforced leucide glass ceramic produced in Liechtenschnein);
• Finesse All Ceramic (American reinforced leucide glass ceramics);
• Cergo (German-made ceramics with a very smooth surface).

"Hollywood" porcelain veneers

Special mention should be made of the so-called “Hollywood” veneers or lumineers (from the English luminary - luminary). These microprostheses have been decorating the smiles of American celebrities for 20 years now. Lumineers were once preferred by George Clooney, Tom Cruise, Angelina Jolie, Gwyneth Paltrow and other stars.

Lumineers are made from the strongest ceramics and are only 0.2-0.3 mm thick. The method of their production is patented and kept secret. These are the only microprosthetic onlays that are fixed to unground teeth.

Manufacturing and installation

The entire process of prosthetic veneers takes about a week and involves two visits to the dentist.

How are veneers made?

Porcelain veneers can be made in two ways:

• layer-by-layer application and firing of porcelain mass (when working with unpressed ceramics);
• injection molding under influence high temperatures and pressure (this is how linings are made from pressed ceramics, which are considered more durable than those made from non-pressed ceramics).

Microprostheses made of zirconium dioxide are manufactured using CAD/CAM technology:

• The CAD system creates a three-dimensional model of the overlay using a computer;
• The CAM system allows you to produce microprostheses according to a three-dimensional model on a highly accurate automatic milling machine (without human intervention).

Most quick way automated creation of zirconium dioxide veneers - using the Cerec device (a set of technologies, equipment and materials for the production of ceramic microprostheses).

How are porcelain veneers installed?

Installation includes the following steps:

1. Choice of color and type of overlay.
2. Odontopreparation (removal of hard tooth tissues). To install conventional veneers and ultra-veneers, it is necessary to grind away from the tooth surface from half to one and a half millimeters. Lumineers are installed without grinding.
3. Making an impression of the prepared tooth.
4. Fixing a temporary plastic overlay (the ground tooth needs protection from an aggressive environment oral cavity during the manufacture of the lining).
5. Laboratory production of veneers based on impressions taken.
6. Fastening the microprosthesis.

When installing lumineers, the second and fourth stages are omitted.

Fixation of ceramic veneers

Ceramic veneers are glued to the teeth with special dental cements (Variolink, Multilink Automix, SpeedCEM, Vivaglass CEM and others). Before applying cement, the tooth is treated with an etching gel, which enhances the adhesion force.

Care

Ceramic veneers require the same care as natural teeth. To preserve their aesthetics and extend their service life, it is recommended:

• reduce the consumption of foods with dyes (the linings will not change color, but the fixing cement may);
• wear a plastic mouthguard for bruxism - pathological grinding of teeth;
• do not subject teeth with veneers to increased stress (do not bite ice, do not open bottles, do not bite nails and hair ends, do not shell seeds);
• Do not miss dental checkups (once every six months).

Life time

1. The shelf life of ceramic veneers is not limited, but on average they last 10-12 years.
2. Overlays with a zirconium dioxide frame have a longer service life.
3. As for lumineers, their manufacturers claim a 20-year service life.

All types of veneers come off over time or break under stress. In the first case, the microprosthesis can be installed again, in the second - not, since they cannot be repaired.

Prices for ceramic veneers

The cost of veneers, taking into account the manufacture and installation of the microprosthesis itself, is:

• from 14,000 rubles for porcelain;
• from 17,000 rubles - from zirconium dioxide;
• from 25,000 rubles for lumineers.

Prices are for 1 tooth. For a complete aesthetic restoration of a smile, as a rule, onlays are needed for ten upper and eight lower teeth.

Advantages and disadvantages

Advantages:

• high aesthetic effect (ceramics differs from composites in that it retains its original color and, with high-quality processing, is no different from a real tooth);
• biocompatibility (ceramic veneers are hypoallergenic);
• durability (compared to composite onlays, the short-term whitening effect and the five-year service life of a conventional filling);
• minimal or zero treatment of the tooth (the tooth is ground much more strongly for a crown).

Flaws:

• high cost (restoration with composite materials is cheaper);
• instability to heavy loads (can peel off and break);
• irreversibility of the preparation (the tooth ground under the veneer will no longer be able to function normally after the onlay is removed).

Photos before and after installation of ceramic veneers

The result of installing ceramic veneers will largely depend on the qualifications of the dentist. You can choose a good dentist in the “clinics” and “doctors” sections of our website.

These prostheses, as the name suggests, consist of a metal frame and a coating of ceramic materials. They are widely used in dental restoration. Putting a metal-ceramic crown on a tooth means making a choice in favor of reliability and quality. When creating metal ceramic crowns used: gold platinum; silver; nickel; cobalt-chromium alloy, etc.

Over time, teeth may acquire an undesirable shade or become covered with unsightly stains, and other surface defects may appear - small cracks and scratches on the enamel. There are other problems caused by incorrect position or slight crooked teeth, significant gaps between them - all this spoils your smile and mood. Aesthetic dentistry is designed to correct such deficiencies, and this is done with the help of microprosthetics.

Do you dream about Hollywood smile? At the Dentalux-M clinic they will help you make your dream come true in just one visit to the dentist! The whole secret lies in relatively new systems for instantly restoring the aesthetics of a smile - veneers. The design is a thin plate that is applied to the surface of the tooth and covers existing defects and imperfections.

Installation of removable dentures ensures the restoration of chewing function, as well as full diction after the loss of several teeth or when complete absence. The reliability of such structures has been verified by many years of installation experience, while the development modern technologies allows you to improve functional and aesthetic properties, use only high-quality biocompatible materials in production. It must be remembered that prosthetics prevents the displacement of remaining teeth, as well as the development of malocclusion, so it is really necessary. You should not be afraid that you will have problems getting used to the orthopedic design: the adaptation process, as a rule, takes very little time.

The development of aesthetic dentistry technologies allows clients to obtain more and more functional, comfortable and invisible structures for dental restoration. One of the most advanced achievements in this area is E-MAX metal-free ceramics.

The process of preparing for prosthetics or implant installation can be quite lengthy. That is why during it there is a risk of developing dentoalveolar deformities. Immediate dentures help to avoid their appearance - temporary structures installed in place of one or more lost teeth (most often in the smile area). Temporary dentures also allow you to:

Prosthetics are indicated when tooth decay is too significant to be restored with fillings. In this case, it is necessary to act as soon as possible: if precious time is lost and saving the tooth turns out to be impossible, in the future only the installation of implants will help restore the integrity of the dentition with truly high functionality and aesthetics. If your dentist recommends that you get ceramic crowns, don’t worry: this design will ensure a quick and trouble-free recovery perfect smile. It is no coincidence that this method of prosthetics is often chosen by people in public professions.

A beautiful smile is every person's dream. Making it a reality today is very simple, because many techniques have been developed. One of the safest and most popular is the installation of veneers. But this procedure has its own characteristics, which everyone who has decided to make their smile perfect should know about. What are veneers

What are veneers

Veneers are dental microprostheses, presented in the form of dental onlays for covering the front teeth. This is a durable plate that masks the front part of the tooth and goes to its cutting edge. Using veneers, you can give your smile an aesthetic appearance and eliminate various defects. This is an excellent alternative to conventional dental restoration. Veneers can be karmic or composite. The second option is used extremely rarely today. This is due to the fact that composite veneers are outdated and have many disadvantages. They are prone to rapid darkening. You can't bleach them; you need to install new ones.

Attention! Unlike ceramic crowns, veneers allow you to carefully cover the surface of the tooth.

How to grind teeth for veneers

Preparation (grinding) of teeth can be carried out in several ways:

• ultrasonic radiation;
• laser radiation;
• chemical substances;
• air abrasive equipment;
• tunnel turning;

Laser

Due to the impulse, the liquid in the tooth tissues heats up, and enamel microparticles disintegrate. This method has the following advantages:

• the procedure is as fast as possible;
• safety and painlessness;
• lack of instruments and medicines;
• nerve endings are preserved;
• quiet operation of the equipment;
• there is no need to treat your mouth with antiseptics - the laser itself does an excellent job of destroying bacteria.

Ultrasound

This procedure has the following advantages:

• painlessness;
• does not destroy soft fabrics;
• microcracks do not form during the attachment process;
• no heating.

Grinding of teeth

Chemical method

Through the use of special chemical compositions enamel and dentin become soft. The duration of the manipulation is 30 minutes. The following advantages are highlighted:

• no heating;
• no anesthesia is used;
• Chips and microcracks do not appear.

Attention! This grinding option is used more often than others on baby teeth. Children are afraid of the sound of the drill, so it is difficult to treat their baby teeth. But a chemical procedure allows you to bypass all the difficulties and qualitatively treat the tooth surface.

Tunnelnoe

For grinding, a turbine unit with diamond and metal tips is used. Advantages of the procedure:

• you can control the speed of the equipment;
• the layer of removed enamel is controlled;
• the results are programmed in advance.

Tunnel turning has disadvantages:

• if old equipment is used, it contributes to overheating;
• anesthesia is used;
• If you work inaccurately, you can injure your gums.

Air abrasive

Preparation is based on the sandblasting method of formatting hard surfaces. Sodium bicarbonate and aluminum oxide are used as abrasives. They are applied to the surface of the tooth increased speed, destroying its bone substance. The procedure has the following advantages: absence of pain, tissue heating, negative effects and microtrauma.

The choice of the appropriate method is carried out together with a specialist. At the same time, he takes into account general state patient, clinic equipment.

The turning process occurs as follows:

1. Indentations are made on the outer part of the tooth. They are horizontal, and their depth is individual, and is controlled by the size of the bur used.
2. The enamel is removed, the thickness of the peeled layer does not exceed 1 mm. There are situations when the depth is greater. This is typical for teeth affected by caries. The edge of the tooth is also processed.
3. Surface polishing.
4. Washing with water, degreasing and drying.
5. Treatment of the tooth with acid, thereby achieving maximum adhesion to the plate.

Is it possible to install without turning?

You can avoid grinding your teeth in the following situations:

1. When the shape of the tooth is corrected and there is no caries on it.
2. When adding volume outer surface teeth.
3. To visually turn a tooth that is in an incorrect position.
4. For severe tooth wear.
5. If the cutting edges of the tooth are uneven.

Installed veneers

Dental veneers: pros and cons

Arguments for veneers:

1. Ceramic overlays are difficult to distinguish from enamel surfaces. They repeat exactly anatomical structure tooth
2. Ceramic plates are not affected by temperature changes. Such structures are characterized by high strength and can withstand significant loads. When using them, there are no stains or clouding on the surface. This will allow you to consume coffee, tea and other coloring foods and drinks.
3. Speed ​​of implementation. You can restore your teeth in 2 visits to the dentist.
4. Veneers give teeth natural whiteness and shine.
5. With the help of veneers you can correct malocclusion, the shape of the tooth and its position relative to the others.
6. The ability to eliminate chips, enamel cracks and other defects.

Arguments against:

1. Porcelain plates do not have high strength and can break.
2. If you do not follow the rules for using porcelain onlays, they may break, and the plates made of composite material may crack.
3. The teeth on which veneers are being installed must first be ground down. Because of this, they lose their original appearance. Hence, you will need to wear veneers throughout your life, or restore your teeth after they are removed.
4. Composite structures are less reliable than ceramic ones. After 3-5 years they need to be changed, as they fade and change color. This is their main drawback.

Important! Veneers can only mask the curvature. To combat it, you need to wear braces or mouthguards.

Service life of veneers

How long veneers will last depends on the type of material used to make them:

• ceramic – 12-13 years;
• composite – 3-5 years.

Features of dental restoration with veneers

The installation process for porcelain and composite veneers is the same and includes the following steps:

1. The initial stage involves preparing the tooth. If there is a seal, replace it with a new one. This will improve the quality of fastening.
2. The dentist, together with the patient, selects the required color shade. It should match the color of your teeth as closely as possible.
3. Before taking measurements, the tooth is ground down. This procedure is based on removing a layer of enamel. These actions will allow the plate not to stand out in thickness from the rest of the teeth.
4. Removing the mold according to which the plate will be made.
5. Installing a temporary plate. It prevents unnecessary influence external factors on an exposed tooth.
6. In the laboratory, plaster models are made, on the basis of which veneers are then created.
7. On final stage veneer is installed. First, they are fixed with a special paste, and then they are checked to see if the color of the cement is suitable. After this, the structures are finally secured.

Important! The following materials are most often used to fix structures: Multilink Automix, SpeedCEM, Vivaglass, Variolink.

Contraindications to the use of veneers

Installation of veneers is not carried out if the following contraindications exist:

• reverse bite;
• there is a large or medium filling on the inside of the tooth being restored;
• severe damage to the lingual surface of the tooth;
• when using resorcinol-formalin (a special paste used for dental purposes) to treat a tooth, further installation of veneers is extremely undesirable;
• bad habits (opening beer with teeth, biting nails or other hard objects);
• bruxism (teeth grinding);
• extreme sports (karate, boxing);
• absence of one or more chewing teeth;
• high wear of teeth (grade 2 and higher).

Important! People with a nail biting habit need to fight it or abandon veneers, otherwise the condition of composite or ceramic plates will quickly worsen.

Do teeth deteriorate under veneers?

You won’t be able to get veneers and forget about them. The fact is that to install the structure it is necessary to grind off the enamel. In a few years the procedure will have to be repeated. But under the veneers themselves, the teeth do not deteriorate; on the contrary, they are protected from the influence of external factors.

Attention! It is necessary to discuss all the details with specialists in advance, since removing the plates on your own is impossible, and reinstallation in a hospital setting will disturb the condition of the teeth, and also requires money and time.

Does it hurt to put it on?

A veneer is a microprosthesis, that is, it is a kind of “additive” to a tooth. The fixation process does not affect the nerve of the tooth and does not injure the soft tissues of the oral cavity. Therefore, there should be no pain during or after installation. When veneers are worn, they do not correct the bite and do not move the teeth, unlike braces. Their main task is to disguise the defect. The only signal that the dentition has changed is a slight “thickening” effect in the front row. At first it feels like something has been glued to your teeth, but after a while such sensations go away.

But there is one unpleasant moment in this whole procedure. It is associated with the treatment of the tooth before attaching the veneer. This treatment involves carefully removing a thin layer of enamel. Because of this, the surface becomes rough, resulting in better adhesion to dental cement. This procedure does not cause pain, but discomfort are present. When the treated surface is covered with an overlay, all discomfort will disappear.

Which teeth can and cannot be fitted with veneers?

For filled teeth

If you carefully read the contraindications, you will see that installing veneers on filled teeth is not recommended. The fact is that the plate will not be able to attach to the surface of the filling. In this case, the doctor suggests that the patient install a crown.

On dead teeth

A dead tooth means a pulpless tooth in which the nerve has been removed. It is not recommended to install veneers on dead teeth; it is best to use lumineers. These designs successfully replace classic crowns.

For healthy teeth

On healthy teeth You can install veneers. Most often, this procedure is performed due to yellowness of the enamel. To solve this problem, porcelain and ceramic veneers are used. They are durable and long term services. Due to them, the smile turns out natural and snow-white.

Consequences of using veneers

Since tooth sharpening is used to install a veneer, this leads to its formation hypersensitivity for hot and cold drinks. The teeth on which the plates are installed may be subject to destruction, and this can only be corrected by covering the tooth with a crown.

Before and after installation of veneers

Dental restoration after veneer removal

To restore teeth after veneers, fluoridation and reminerilization are most often used.

Fluoridation

Fluoride is a mineral that is essential for teeth and normal enamel formation. When the enamel is thinning, many clinics offer clients fluoridation of teeth. This procedure involves restoring the mineral composition of tooth enamel using fluoride. Thanks to it, damage to the enamel is reduced, its expiration is prevented and cracks are eliminated. This is an excellent prevention of caries and the ability to relieve dental hypersensitivity to the effects of cold and heat, sweet and sour foods.

Fluoridation of teeth should be carried out carefully, since an oversaturation of fluoride in the body is dangerous for humans. Dental fluoridation of teeth using fluoride varnish is performed no more often than once every 6 months.

Remineralization

This enamel restoration procedure also occurs when using a special varnish. In addition to fluorine, it contains a lot of other useful components. They are able to restore the mineral composition of the enamel and prevent its resolution.

Carry out remineralization every six months. The advantages of the procedure include the minimal risk of fluoride oversaturation. This distinguishes remineralization from fluoridation. You can restore enamel with varnish only after completing the full course, since this procedure has a cumulative effect.

Aligners as an alternative for crooked teeth

Alternative methods of dental restoration

Braces

Braces are fixed orthodontic devices. Their installation is carried out on the outside or inner side dentition for straightening teeth, correcting bites and eliminating other defects.

The use of orthodontic devices will allow you to acquire beautiful smile, and also avoid many problems (diseases of the gastrointestinal tract, damage to the tissue of the cheeks or tongue). They can be worn by teenagers who have completed the process of dental formation, as well as by adults.

Aligners

These are dental guards that come in the form of durable devices. They are made from individual impressions and cover the entire surface of the teeth. Such products apply slight pressure, as a result of which the teeth are aligned. In dentistry, mouth guards made from silicone and plastic are used. Regardless of the type of material, the aligners are completely transparent and invisible on the teeth after installation.

Prosthetics

Dental prosthetics today are divided into two types:

1. Fixed. Dentures of this type are firmly fixed to the teeth using various cements. They do not require long-term adaptation and are fully consistent with the anatomical and functional features missing or decayed teeth. Removable prosthetics can be performed in two ways, taking into account the type and size of the defect. Fixed structures include crowns, inlays, and bridges.
2. Removable dentures are a design whose base can be made from various materials. They attach it to her artificial teeth made of plastic or porcelain. The fastening of such a structure in the cavity is determined by the type of prosthetics. The suction effect, clasps, micro-locks, and telescopic crowns are most often used.

Veneers are in great demand in dental practice today. And this is not surprising, since such structures are characterized by increased strength, aesthetics and safety. However, it is not always possible to install them, so it is important to consult with a dentist and discuss the features of this dental restoration procedure.

Veneers can be ceramic, made from ceramics (porcelain), zirconium - from zirconium dioxide, composite - using filling material. Ceramic and zirconium veneers are made by an orthopedic surgeon in conjunction with a dental laboratory. While composite veneers are in the dentist's chair.

Different materials for making veneers have both pros and cons. In the case of composite veneers, the advantage is the speed of production - in one visit. The disadvantage is the low strength of the material and low masking ability when the tooth’s own color changes. For example, if a tooth has a discoloration, that is, it is darker than the rest, a composite veneer will not eliminate this defect, especially on long time- dark tissues of your own tooth will shine through the composite. In addition, such veneers require correction, and most often they need to be replaced with more durable structures. Composite veneers last a maximum of 3-5 years.

Veneers made of ceramics and zirconium dioxide have much more advantages - high-quality modern materials are used for their production, due to the transparency of which teeth shine and look more natural. The absence of metal allows you to get an excellent result, as it makes it possible to choose the color of the veneers to match the color of your own teeth as accurately as possible. The service life of ceramic and zirconium veneers is on average 10-15 years. It is believed that zirconium dioxide veneers have higher strength and a greater number of shades for color selection than ceramic ones. Another advantage of this material is its ability to provide higher aesthetics in difficult clinical situations. The advantages of ceramic and zirconium veneers also include the absence allergic reaction on material, strength and lightness. Such veneers do not change color and are metal-free structures. For allergies to metal metal-ceramic crown contraindicated.

The disadvantages of ceramic and zirconium veneers include:

• inability to restore the original appearance of the tooth after removing the veneer;
• tooth turning;
• care for veneers, periodic polishing of veneers at the dentist.
