Today, the procedure for restoring damaged teeth is becoming increasingly popular. In this article, you will learn about the main indications for the installation of veneers.
What are veneers?
A veneer is a thin plate that covers the vestibular surface of the tooth. The thickness of such a plate, as a rule, does not exceed 0.5 mm. Today there are two types of veneers:
- Made by dentists.
- Made by orthopedic dentists.
In fact, both types do not differ in anything, except for the material of manufacture. Therapeutic veneers are made from composite filling materials, while orthopedic veneers are made from ceramics.
If the question is which of the two types of veneers is better, then undoubtedly the best option would be a veneer made by an orthopedic dentist, because it is made of ceramics. And ceramics, as you know, have excellent aesthetic qualities. Ceramic veneers do not give themselves away, they are completely identical to natural teeth. In addition, they fit better to the dental tissues, which reduces the risk of developing a carious process at the point of contact with the tooth to zero.
How are veneers made?
In order for the veneer to please its owner for a long time, it must be installed on a well-treated tooth. For this reason, dentists prescribe an x-ray before starting treatment to see what condition the tooth tissues and bone tissue around it are in. Usually, teeth are depulped before installing veneers. Therefore, after the patient undergoes endodontic treatment of the canals of the tooth, he is sent for a control x-ray. This picture should show whether the root canal treatment is of high quality. The canal should be sealed evenly, over its entire length, the filling material should not extend beyond the top of the tooth.
If the tooth is well cured, the dentist proceeds to process the tooth under the veneer. After turning, an impression of the oral cavity is taken (preferably a two-layer one). After that, the doctor sends the impression to the dental laboratory for casting a plaster model. It is on the plaster model that the veneer will be made in the future. As soon as the veneer is ready, it is tried on in the patient's mouth, adjusted according to the bite, if necessary, and then fixed with a filling material. Grind, polish and cover the tooth with fluoride varnish to strengthen the enamel layer.
If we compare two types of veneers with each other, then orthopedic ones have several advantages:
- Firstly, ceramic veneers have perfect aesthetics. Composites, no matter how hard you try, do not give such aesthetics.
- Secondly, the strength characteristics of orthopedic veneers are higher.
- Thirdly, the service life of ceramic veneers is more than fifteen years.
Fourth, orthopedic veneers, unlike therapeutic veneers, withstand and distribute the masticatory load in the same way as natural teeth.
The negative side of ceramic veneers is:
- It is made much longer than composite ones.
- High price.
- These veneers do not repair chips.
Veneers made of composite materials are also not without positive aspects:
They are relatively inexpensive; are made in one visit; if necessary, they can be easily removed and they can restore the chip.
However, at the same time, they have significant disadvantages:
Not a single ceramic veneer has lasted fifteen years due to the fact that such plates are more fragile. For this reason, they break more often than veneers made at an orthopedic appointment. Also, a significant drawback is that after three years of operation, the composite veneer begins to change its color.
Indications and contraindications
Like any dental procedure, veneering is not without indications and contraindications.
Veneering is the process of making and installing a veneer.
The indication for veneer is:
- Chipped corner of the crown of the tooth.
- Trema and diastema between teeth.
- wedge defects.
- Increased grinding of the enamel layer of the tooth.
- Irregular tooth shape.
- Fillings worn out over time that spoil the aesthetic properties of the tooth.
- Tooth pathology of non-carious origin (tetracycline teeth, fluorosis, hyperplasia, hypoplasia.
Contraindications to tooth restoration with veneers:
- Developing carious process or complication of carious process in the form of pulpitis or periodontitis.
- Periodontal disease (tooth mobility).
- Too thin enamel layer of the tooth.
- Cracks in enamel.
- Parafunction of chewing muscles - bruxism.
- Incomplete eruption of the tooth.
- Incorrectly formed bite (straight).
If the patient has at least one of these contraindications, he is immediately denied veneer. The only possible method of restoring destroyed tooth tissues is to cover the tooth with an orthopedic crown.
