Tooth ceramic veneers: photos before and after, indications and contraindications, dentists' advice

What are Veneers Veneers( laminates) are called thin and strong plates, attached to the surface of the tooth as a lining material.With their help, the color and shape of one tooth as well as the whole dentition are adjusted.Their difference from crowns lies in the fact that they cover not the whole tooth, but only its surface.

Application of veneers to improve the appearance of teeth The front teeth with these microprostheses get an ideal appearance, which can not be obtained with the help of restoration by filling materials or bleaching.The smile looks very attractive.The photos shown in the article perfectly demonstrate this.

If you evaluate the veneers before and after installing them, then undoubtedly the result will exceed all expectations.Such impeccable aesthetics of teeth are created, which you could only dream of earlier.

Indications and contraindications

Indications for veneers:

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

Contraindications:

incorrect bite( direct or reverse);
if abnormal abrasion of teeth has reached the second degree and higher;
absence of chewing teeth, usually the sixth, seventh;
if a person is engaged in traumatic sports, such as boxing;
having a habit of grinding his teeth;
a habit to gnaw nails, open the caps with teeth, snack a thread, crack nuts and so on;
if previously dental treatment was performed using resorcinol and formalin.Veneer in this case will drop completely;
if the internal tooth surface is very badly damaged;
the presence of a large seal on the side of the tongue.

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

Types of veneers

Veneers are of two types: composite and ceramic.

Ceramic veneers

In what cases do veneers are put on teeth Ceramic veneers are made of 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.Even in a long period of time, ceramic microprosthes do not fade or darken.They are very reliable, have a long service life of , but they can not gnaw nuts or open bottles.The only drawback of ceramic veneers 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.The alignment of teeth with porcelain microprostheses looks very nice when they are applied immediately to the whole dentition.

Composite veneers

Composite laminates have significant shortcomings:

composite microprosthes gradually begin to darken and need to be replaced.This lack is not present in ceramics, because never darkens and does not lose its original appearance;
aesthetics leaves much to be desired.Often there are situations when composite microprosthesis eliminated the unsuccessful restoration of teeth, but in the end they were noticeably different from the natural ones in color and transparency.When installing ceramic veneers, this would not have occurred;
they are quite fragile and they can not bite off solid food;
composites are permeable material and can be stained with tea, red wine and other coloring food.

Indications for the installation of veneers

How long does the process of installing veneers on teeth take place?

For and against installation of veneers

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

Veneers or crowns?

If there is at least one contraindication to the use of veneers, it is better to install crowns.But for the crown is necessary to grind the tooth from all sides to 1.5-2 mm, and to install the laminate, remove the upper layer of the enamel to a slight depth of 0.3-0.5 mm from the front surface, and at the cutting edge - on1 mm.As a result, the dental tissue has great safety, which means that the tooth itself will last longer.Therefore, it is better to install the veneers.

Veneers or restoration?

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

Restoration made of light composites is short-lived.This is due to the peculiarity of the seal of the seal to the dental tissues.Often a dark line or repeated caries forms between the filling and the tooth.
Restoration after a while begins to darken, because of this it becomes necessary to replace the filling material.
Filling material is more difficult to restore the color and transparency of the tooth.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, this is very evident because of poor quality.
The highest quality restoration will still yield to ceramics in aesthetic properties.Over time, any seal begins to darken.

Veneers or braces?

Curved front teeth can be made even with veneers or braces.Necessarily for this purpose consultation of the doctor-orthopedist is necessary.A small curvature is eliminated by laminates, but if it is expressed very strongly, then braces will come to the rescue.

Service life of veneers

Veneers look very beautiful.But many people have the question of how long they last.Suddenly, the facing plate will fall out after the first reception of solid food.

Composite veneers serve as much as fillings during restoration - 2-3 years, and in some cases the service life reaches 7 years.These microprosthes need to constantly polish the , but they still fade and darken.

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

Ultra-thin porcelain veneers can regularly serve more than 20 years.
