Veneer - a thin plate that covers the teeth. Veneers look great, have good working qualities and useful features. These semi-transparent overlay hardness comparable to the hardness of the tooth. They allow you to change the color of teeth, shape, correct dentition defect and achieve a dazzling smile. Just look photo veneers before and after the procedure.  Veneers - the special plate to cover the teeth

The very first began to use the so-called Hollywood veneers - white plates that are attached to the front of the tooth. Later, the full (cosmetic) plate. Cosmetic plate not only improves the appearance of the tooth, but also protect the tooth, which began to collapse. Due to the considerable thickness of veneers at a time had to remove a layer of the tooth enamel. Modern veneer - a combination of aesthetics and protection of the teeth. Modern veneer thickness less than half a millimeter, which minimizes the removal of tooth enamel layer.

Indications for use of veneers

Veneers to teeth mounted patients tooth color changing with age, by changing the shape of the teeth due to abrasion, trauma, dental enamel pigmentation when not subjected to bleaching (fluorosis pigmented enamel cracks, tetracycline teeth).

Dentists are usually advised to install veneers on the teeth in the presence of diastema, with underdeveloped (spinous) teeth enamel which is destroyed, as well as non-compliance bite transverse dimensions of the teeth, with a slight shift of the tooth along the vertical axis. These plates are also worn at the rough contours of the necks of the teeth, gingival smile, there are many defective seals when changing the group membership of the tooth (eg, using canine veneer can be converted into lateral incisor).

Advantages and disadvantages of porcelain veneers

The teeth using porcelain veneers are absolutely natural look. In a review of the veneers is said that they do not discolor with time, they will not be stained. In the restored teeth in the future hardly occurs accumulation of plaque.

But we should not forget that with the strengthening of data plates eroded tooth enamel. Ground off the enamel will be impossible to recover without the use of any means of restoration. Because of its fragility and brittle veneer can easily peel off from the tooth. Another drawback is that the adhesive material during the installation of the veneer will protrude slightly on the edges, turning the edges of the veneer. Some reviews of the veneers is said that they can not be fitted with the gum disease. You also can not use them on the destroyed and thinning teeth prone to caries.  Veneers: before and after the installation of

Types of veneers

Veneers are usually made of zirconium oxide ceramics and / or composite. Composite veneers can be made direct and indirect ways. When installing composite veneers made directly, the dentist treats only the portion of the tooth that needs to change. The advantages of the composite plates include quick production of small and stitching of dental hard tissues. For example, tooth gap closes without any turning of the teeth. In the direct method, the doctor uses mininapolnennye, hybrid composites and nanocomposites. Indirect Composite panels are usually installed at significant violations of the tooth surface.

In composite veneers are many shortcomings. This increased abrasion, swelling of the composite in the oral cavity in a moist environment, often leads to irritation and bleeding gums, gingivitis. The disadvantages of composite plates include their fragility, unsealed edges of the restoration and the restoration of the borders of pigmentation over time. Composite veneers are characterized by low strength and low masking capability with a significant change in tooth color. They are unstable to the perception of alcohol substances. Composite restorations can serve patients from three to nine years. Lifetime composite plates depends on the level of oral care, as well as the functional load on the plate.

Porcelain veneers are currently considered the most hygienic, gentle and long-lasting. They are very easy to clean. They are practically not formed plaque. In the physical characteristics of ceramic veneers are very similar to tooth enamel.

Ceramic plates are made in the laboratory. First, the doctor sends the impression of the patient's teeth to the dental laboratory. The laboratory porcelain veneers made the classic way (by layering ceramic powders), by press ceramics (injection molding), or by milling and-cast units. After coloring the veneer made with special paints (according to the color of adjacent teeth) Ceramic veneers fixed with cement on the tooth. Many reviews of the veneers confirmed that ceramic plates are stronger and more durable than composite veneers. The result of the installation of porcelain veneers specialists typically exhibit before the procedure. Photo veneers before and after the procedure well prove its success.
