Indications and contraindications

Indications for prosthetics with veneers:

improving the color and shape of the tooth;
if after the restoration or whitening of teeth their condition worsened;
to give a smile charming beauty and aesthetics.

Contraindications:

wrong bite (direct or reverse);
if the pathological abrasion of teeth has reached the second degree and higher;
lack of chewing teeth, usually sixth, seventh;
if a person engages in traumatic sports, such as boxing;
having the habit of gritting your teeth;
the habit of gnawing at the nails, opening the caps with your teeth, snacking on the thread, cracking nuts, and so on;
if previously dental treatment was carried out using resorcin and formalin. Veneer in this case will fall out completely;
if the internal tooth surface has collapsed;
the presence of a large seal from the side of the tongue.

In the latter two cases, the installation of crowns is recommended. If the patient wants with the help of veneers to improve the appearance of the whole dentition, in which one tooth is destroyed more than necessary, then in such cases the crown is put on the destroyed unit, and all the others - veneers. To make the teeth look like a single unit, the crown and veneers must be made of the same material.

Types of veneers

Veneers are of two types: composite and ceramic.

Ceramic veneers

For the manufacture of ceramic veneer use porcelain or zirconia. The photo shows standard veneers with a thickness of 0.3-0.5 mm.

Ceramic laminates have their pros and cons. They are used to create a Hollywood smile. Ceramic micro-prostheses, even after a long period of time, do not grow dull or darken. They are very reliable have a long life, but they can not nibble nuts or open lids in bottles. The only disadvantage of ceramic veneer is their high cost.

Ceramic porcelain veneers are very popular among those patients who need a Hollywood smile. It is through this material that this effect is achieved. Alignment of teeth with porcelain microprostheses looks very nice when they are superimposed on a whole tooth row.

Composite veneers

Composite laminates have significant drawbacks:

composite micro-prostheses gradually begin to darken and there is a need to replace them. There is no lack of ceramics, because aboutnever gets dark and does not lose its original appearance;
aesthetics leaves much to be desired.Often there are situations when composite microprostheses eliminated unsuccessful restoration of teeth, but in the end they were noticeably different from natural ones in color and transparency. With ceramic installation veneers of this would not have arisen;
they are quite fragile and they can not bite off solid food;
Composites are permeable and can be stained with tea, red wine and other food coloring.

Pros and cons of installing veneers

Many people often think that it is better to correct the teeth with laminates or choose another way to improve their appearance.

Veneers or a crown?

If there is at least one contraindication to the use of veneers, it is better to install the crowns. But under the crown need to grind the tooth on all sides by 1.5-2 mm, and to install the laminate, remove the top layer of enamel to a small depth of 0.3-0.5 mm from the front surface, and at the cutting edge - 1 mm. As a result, the dental tissue has a great preservation, which means that the tooth itself will last longer. Therefore, it is better to install veneers.

Veneers or restoration?

Restoration of light-polymer composites inferior to laminates in many respects.

Restoration, made of light composites, is short-lived. This is due to the peculiarity of the seal to dental tissues. Often a dark line or repeated caries forms between the filling and the tooth.
Restoration after some time begins to darken, because of this there is a need to replace the filling material.
Filling material is more difficult to restore the color and transparency of the tooth. The ideal option is the use of ceramics, which is very similar to tooth enamel in structure, transparency and other indicators. If the front teeth are restored, it is very striking because of poor quality.
The highest quality restoration will still be inferior to ceramics for aesthetic properties. Over time, any filling begins to darken.

Veneers or braces?

Curved front teeth can be made even with veneers or braces. It is necessary to consult an orthopedist for this. Small curvature eliminated by laminates, but if it is expressed very strongly, then braces will come to the rescue.

Lifetime of veneers

Veneers look very nice. But many people ask how durable they are. Suddenly, the facing plate will fall out after the first solid food intake.

Composite veneers serve as much as fillings during restoration - 2-3 years, and in some cases the service life reaches 7 years. These micro prostheses must be constantly polishedbut they still grow dull and darker.

Ceramic micro-prostheses can last for a very long time, unless the teeth get any mechanical trauma. Ceramics does not darken, does not tarnish and does not lose luster. After 10 years of use, veneers may fall out. This is due to the adhesive with which they were fixed. In this case laminate can be easily glued back, but only a dentist should do this.
