Veneers

Dental veneers are thin-walled plates that can be used to:

  • correct the shape and defects of teeth;
  • restore natural beauty, enamel color;
  • close small interdental spaces;
  • visually change the position of the incisor or canine.

Composite and ceramic veneers for teeth are aesthetic microprostheses that are attached to the front surface of the teeth. They are made of porcelain, zirconium dioxide, ceramics or photopolymer filling material.

What teeth are placed on?

As a rule, veneers are installed on the front teeth – this is the “smile zone”. You can install one or more units at once. But, in order to achieve the maximum aesthetic result, dentists recommend restoring 4 upper and 4 lower anterior incisors at once, as well as 2 upper and 2 lower canines.

It is irrational to put these micro prostheses on molars. Even the strongest ceramic plates will not be able to withstand the regular chewing load.

Types of veneers by material

Composite

Advantages:

  • low price;
  • production and installation in one day;
  • ease of maintenance.

Flaws:

  • fragility (compared to other materials);
  • limited service life (3-5 years);
  • look unnatural (they cannot fully convey the anatomical features);
  • quickly lose color, fade (for example, due to food dyes).

Ceramic

Advantages:

  • high strength;
  • naturalness (according to optical and physical properties, it is close to enamel);
  • preservation of tooth tissues (minimal preparation);
    long service, during which they do not change color.

Flaws:

  • the presence of contraindications;
  • high price.

On the refractor E-max

Advantages:

  • facing ceramics do not change color after 10-15 years (not exposed to food dyes);
  • strong fixation;
  • plates made of glass-ceramic e max do not require special care;
  • small material thickness e max (0.3 mm).

Flaws:

  • high price.

Made from zirconia

Advantages:

  • zirconium dioxide is resistant to temperature extremes;
  • serves 10-15 years;
  • very durable;
  • does not cause allergic reactions (only in rare cases).

Flaws:

  • unnatural (matte surface);
  • The zirconium dioxide frame is quite hard to attach.

Veneers or Lumineers: what to choose?

Let’s compare lumineers with microprostheses on a refractor

Lumineers

  • They are made using patented porcelain technology.
  • Very thin – 0.2-0.3 mm.
  • They are installed without preparation (the exception is cases when the curvature of the teeth is observed).
  • Relative indications for smile correction (it is difficult to preserve the natural color due to their transparency).

On the refractor

  • Frameless (high-strength facing ceramics are used).
  • Thin, 0.3-0.5 mm thick.
  • To install veneers on a refractor, micro-grinding of tooth enamel is required.
  • Provides a natural shade and natural light transmission.

Fabrication and installation of veneers at Tsypin Dentistry.

  1. In most cases, you will need to visit the dentist’s office at least twice.
  2. The doctor listens to the patient’s complaints, collects an anamnesis and performs an instrumental examination of the teeth (the condition of the mucous membrane and tooth enamel is assessed). In addition, laboratory and radiological studies may be required at this stage.
  3. Removal of problems identified during the inspection. Treatment of teeth – caries and other non-carious lesions of hard dental tissues. If this is not done and the veneer is placed on the incisors affected by caries, this will lead to the rapid multiplication of the infection.
  4. A special paste applied to the impression tray is pressed against the patient’s teeth. Also, the dentist evaluates the individual characteristics of the teeth (their shape, position, direction of the axes) and offers to choose the shade of the filling material.
  5. Takes 7 to 14 days. To achieve an accurate result, dental technicians use modern microscopes that help to achieve the maximum density of the marginal fit of the lining to the tooth. Thanks to this, the structure is fastened securely, for a long time.
  6. Enamel is cleaned from plaque with special means (do not contain fluorine and oils). Under anesthesia, the surface of the tooth is turned. Fixing the veneer with a special adhesive. Structural adjustment and bite check.

    Indications for installation

Tooth restoration is carried out in the following cases:

  • when chips and cracks appear on the enamel or due to its strong abrasion;
  • when there are enlarged spaces between the teeth;
  • if there is a change in the color of the enamel (for example, in connection with the use of antibiotics from the tetracycline group);
  • with the appearance of a wedge-shaped defect;
  • if functional defects are found after fluorosis treatment;
  • replacement of the old plate.

Advantages and disadvantages of installing veneers

Advantages
  • Quick manufacturing/installation (2-3 visits).
  • Minimum care requirements.
  • Relatively long service life (from 3 years).
  • Minimal grinding of tooth enamel.
  • The ability to choose the shade of the material to match the color of the teeth.
  • No discomfort (full fit)
  • Additional dentine protection
Flaws
  • Do not bleach (loss of color of the plate entails its replacement).
  • Irreversible process due to preparation (impossible to remove without replacing with a new design).
  • Sometimes they look unnatural (depending on the specialist and the material).
  • The destruction of dental tissues and the spread of caries (with improper
  • installation in economy class clinics).
