Veneers: Pros and Cons
Vining, veneers, lumineers, tooth coatings, tooth pads. In the article we will tell you what it is, whether they are harmful to health and how much it costs.
Veneers are thin overlays with a thickness of 0.2 mm as an eye lens (lumineers) to 0.5 mm (veneers), designed to cover the external tooth surface, sometimes part of the inside.
Veneers are used to improve the appearance of teeth. Veneers will not replace a missing tooth and will not cope with the wrong bite, but they can mask ugly tooth defects.
You can make a veneer as a natural tooth, or you can get snow-white, as in advertising. The main purpose of veneers is aesthetics.
The technology for making veneers appeared in the late 30s of the last century and was introduced by American doctor Charles Pincus, who treated Hollywood actors, creating dazzling smiles before shooting. Due to the fact that at that time there were no adhesive cements, veneers stayed on their teeth for a maximum of several days. We can safely attribute this technology to the past history. From there, the well-known definition of “Hollywood smile” came to us.
The main indications for installing veneers:
Changes in the color of teeth as a result of treatment of complications of caries (that is, treatment of tooth canals), taking antibiotics to form their teeth (tetracycline), fluorosis, hypoplasia;
Tortoanomalies of teeth (crooked or rotated) or abnormal abrasion (short teeth);
The presence of three and diastemas (wide interdental spaces);
Gummy smile (when you can see most of the gums when smiling);
Weak tone of the skin and muscles of the lower part of the face (old man’s face);
Set veneers on chewing teeth to increase occlusion.
Which is better: veneers or crowns?
Veneers and crowns are different designs in terms of their functions. Veneers enhance the look of a smile. Dental crowns are made when the tooth is destroyed due to caries and its complications.
Crowns restore the function of the tooth and protect it from the re-occurrence of carious processes.
What is better to put veneers or crowns on the front teeth should be decided by the doctor, referring to objective indications and contraindications.
Contraindications to the installation of veneers:
Deep bite (malocclusion);
Poor oral hygiene, more precisely, its absence.
Can veneers be placed if the bite is wrong?
Is it possible to put veneers if the tooth is without a nerve?
The final decision is made by the doctor, but if there are problems with a bite, incorrect prosthetics can lead to structural failure and disruption of the TMJ.
Depending on the manufacturing method and the material of the veneers, they can be divided into: direct and indirect.
The direct method of manufacturing veneers
Direct veneers are made by the dentist directly in the patient’s mouth. In this case, composite materials are used, similar to those from which fillings are made, and special composite paints are used to create various effects of “living” teeth.
That is, the tooth is processed (enamel is removed) to the desired thickness from about 0.3 to 0.7 millimeters, and then veneer is formed in layers on the tooth surface, grinding and polishing are completed. Usually, this is called tooth restoration (art restoration, etc.).
If you want to correct the aesthetics of only one tooth or to correct a chipped tooth, then this method would be an ideal option.
The advantage of this method is the conditional low cost of manufacture and a short time.
The disadvantages include a short service life, fragility of the design and imperfect aesthetics.
Indirect veneer manufacturing method
The indirect method is much more complicated – you will need several visits to the doctor. But, with the advent of the 3D scanner, the patient sees what he gets at the exit and can always adjust the shape and color of the veneer.
At iStomatolog, the patient’s teeth are first scanned and, first, the mockup of future teeth is modeled for transfer to the patient’s oral cavity. At this stage, we consider the shape, size of teeth and the depth of preparation (grinding of teeth for applying veneers) of teeth. Sometimes, after this stage, it is clear that the teeth do not need to be grind at all and then lumineers can be made.
The next stage is the preparation of teeth for veneers, the scanning of treated teeth and the manufacture of temporary veneers at the same visit using special PMMA material. The scan is transmitted to the milling cutter and the milling cutter makes veneers from ceramics.
The next step is the removal of temporary structures from the teeth and fixing the permanent.
The materials from which veneers are made
Veneers can be:
From zirconium oxide.
