Composite veneers. This type of veneers is obsolete and less preferred, since it has many disadvantages from an aesthetic point of view and limitations in service life. The advantages of using them are the speed of installation (in the dentist’s office) and the sparing technique.

A variety of ceramics from porcelain – Hollywood laminates. The thickness of such plates is only 0.2 mm. By comparison, with conventional porcelain veneers, they are easier to use and have a longer service life. The technique of their manufacture allows you not to grind the enamel of the tooth. Hollywood veneers can be glued on artificial crowns.

So, now in more detail. What you need to know about therapeutic veneers:

• Firstly, they should not be resorted to in cases where it is only necessary to improve the appearance of the tooth, but in situations of a substantially destroyed tooth, of course, if this is possible in every single clinical case, since orthopedic veneers here can be useless from a purely practical point of view vision or because of their inability to apply them;
• Secondly, composite materials have a limited (standardized) color gamut, so in some cases it will not be possible to choose the exact color of the enamel, but the doctor will warn you about it, although more than two-thirds of the patients of the presented set of flowers are enough;
• Thirdly, do not resort to cheap materials: they are more fragile, more porous, and therefore easy to color in the color of food and beverages consumed: today the most expensive composite materials still cost an order of magnitude lower than ceramic (porcelain) materials.

Orthopedic veneers and lumineers. What you should know about these microprosthetics:

• Firstly, use them only to improve the aesthetics of the dentition, as porcelain (ceramic) in composition is one of the materials closest to the enamel of the tooth – for example, it also passes light in exactly the same way, therefore it almost perfectly fits into the visible line of a smile – this concerns, first of all, lumineers;
• Secondly, do not put orthopedic veneers and lumineers, if you are engaged in extreme, traumatic sports, like to open bottles with your teeth, gnaw on bones or “snap” nuts, suffer bruxism (involuntary gnashing of teeth) – all this will bring to nothing all the efforts of the dentist and the money you spent; with bruxism, you should consult an orthopedist who will make you a personal cap for wearing at night to get rid of a negative stereotype of jaw movements or an incorrect bite;
• Thirdly, for classical veneers, it will most likely require a minor turning of the tooth enamel – usually by 0.3-0.7 millimeters – so in the future you are practically doomed to wear veneers for life as a protective element, while expensive lumineers do not need to be turned;
• Fourthly, as already mentioned, veneers and lumineers can be made from ceramics (porcelain) or from zirconium or aluminum oxides, which are much stronger than ceramics, but they do not let light in, and therefore the attentive interlocutor may notice the unnaturalness of your teeth – as, for example, men determine silicone breasts in women – so you should make a weighted choice: either lumineers from porcelain with a service life of 5-8 years, or veneers of metal dioxides with a wear time of 15-20 years;
• Fifthly, only proper oral care, appointed by the dentist, and observance of the safety conditions will help not only justify the design life of veneers and lumineers, but also increase it 2-4 times.

Stages of manufacture of veneers

There are two technologies for manufacturing porcelain veneers:

1. Layer-by-layer application of ceramic mass with subsequent baking (unpressured ceramic).
2. Injection molding at high temperature under pressure (pressed ceramics). This technology allows you to create very strong veneers. Their service life is longer than that made of non-pressed ceramics.

Composite veneers can be manufactured in two ways:

1. In the dentist’s office. Such designs are called veneers therapeutic or direct veneers. The doctor removes a small layer of enamel on the front surface of the tooth, and then, layer-by-layer applies a light-polymer composite material, restoring its surface.
2. In the dentist’s office. For this, the dentist sharpens the tooth under the veneer and removes the impression. In the laboratory, a plaster cast is made for the impression. It will be modeled on a composite veneer.

Production of porcelain veneers

1. Preparation under the veneers of the teeth and making a three-dimensional impression.
2. The computer simulates the future veneer.
3. Grinding of the structure on a milling machine made of zirconium dioxide (without human participation).
4. Temporary laminate is applied to the turned-on tooth.
5. Treatment of the inner surface of the veneer (giving it a roughness) for better installation.
6. Apply cement to the tooth and the inside of the plate and fix it to the tooth.

Indications for installation

1. Severe yellowness of teeth (tetracycline teeth).
2. Changing the color of teeth due to depulpation.
3. Fluorotic teeth.
4. Erosion of tooth enamel.
5. Teeth defects that have extensive damage to hard tissues.
6. Incorrect position of the teeth (crowding of incisors, turning of the tooth around the axis). The alignment of the teeth with veneers looks aesthetic, if the plates are not applied to one tooth, but immediately to several.
7. Abnormal tooth shape.
8. In the case when the restoration measures have not produced an effect.
9. The presence of old fillings, the color of which differs from the color of the teeth.
10. Chipped teeth.
11. The presence of large interdental spaces.
12. Create a Hollywood smile.

Contraindications

• Abnormal abrasion of teeth.
• Bruxism (gnashing of teeth).
• Bad habits: gnaw nails, open bottles, crack nuts, etc.
• Veneers should not be placed if the patient has an incorrect bite.
• Lack of 6 to 7 chewing teeth.
• Tooth decay from the tongue.
• Presence of a large filling on the inside of the tooth.
• Presence of a risk of injury to the front teeth (enthusiasm for boxing, etc.)

How to install

Installation of veneer structures occurs in several stages:

1. The preliminary stage. At this stage it is necessary to determine the material from which the veneer will be made, and also to agree the color of the future plate.
2. Dissection of the tooth. Depending on the thickness of the veneer plate, a layer of hard tooth tissues is removed from the front surface of the tooth.
3. Removing the impression from the teeth and sending it to the laboratory.
4. Installation of a temporary plate made of plastic.
5. A gypsum model of a patient’s teeth is made in the laboratory. One of the above-described methods is used to produce a ceramic plate.
6. Fixation of veneers on the tooth with a special glue.
7. Removal of excess cement and evaluation of bite.

You can install veneers without grinding your teeth. Modern dentistry has in its arsenal this kind of dental structures, which are called “lumineers.” Lumineers are finer constructions than veneers. They are like petals, which are glued to the surface of the teeth with the help of dental glue.

Lumineers are standard and individual. Individual designs are made in laboratory conditions. Standard – are selected, like nails from the set. about glue.nkie than veneers of construction. They are like petals, which are glued to the surface of the teeth with the help of dental glue.

Rehabilitation and rehabilitation

Once the veneer is installed, you can lead a normal lifestyle. Follow the doctor’s recommendations for the correct use of the structure.
Probably, that in one – two weeks it will be necessary to visit again the stomatologist for carrying out of check inspection. The doctor should check the location on the tooth structure and monitor the gum reaction for the presence of a veneer plate.

As a result of turning the tooth may show increased sensitivity of the tooth to cold or hot drinks. The teeth on which the veneers are installed can be destroyed, which can become an indication for the crown covering the tooth.
