Composite veneers
(1)
Contents:
Modern composite veneers are aesthetic overlays made of a multi-component photopolymer material. They help to correct the shape of incisors and canines, brighten the colour of the enamel and hide minor defects (stains, cracks and chips).
Pads are placed on the front ten teeth of each jaw. They are attached using adhesive composition or adhesion (intermolecular interaction). If necessary, you can fit the plates on only 1-2 teeth with cosmetic defects.
Contraindications to the composite veneer’s placement include:
- severe bite disorders;
- bruxism;
- untreated caries, pulpitis, and periodontal disease;
- over-sized fillings.
Correctly performed artistic restoration with onlays creates the effect of a perfect smile. The pads look like the patient’s natural teeth, impalpable in the mouth. The taste sensation, chewing and articulation remain unchanged while wearing them.
Advantages of composite veneers
Advantages of composite veneers
The advantages include the following:
- the following rapid positive results;
- no waiting period;
- instant absorption;
- no sense of discomfort;
- no interference with talking and eating;
- no allergic reactions.
Dentistry uses two methods of onlays manufacturing and placement – direct and indirect. In the first case, the work is done directly on the patient’s teeth during a single visit to the doctor. The second case involves the laboratory manufacturing of the fillings and their placement in the doctor’s office.
Advantages of the first option: fast treatment, reasonable price, shallow teeth grinding, and the possibility of quick adjustment of the size and shape correction. Advantages of the second option: high strength, aesthetics and durability of the onlays.
High-quality composite veneers with proper and regular care can last for five years and more. Then, if necessary, the veneers can be removed and replaced with new ones.
When placing the veneers, the ground surfaces of the canines and incisors are treated with a special compound. It prevents the growth of bacteria and stimulates remineralisation. As a result, correctly placed veneers bond to the teeth tightly, without gaps and hold them firmly for years.
After bonding the veneers, patients are not recommended to eat intensely staining products and chew on solid foods (carrots, bones, nuts, seeds). In addition, following proper oral hygiene, protecting teeth when playing sports (boxing, hockey), using certified toothpaste, and visiting the dentist regularly is necessary.
What Are Composite Veneers?
Durable and lightweight composite veneers are a base made of a multi-component material. It covers the tooth’s front surface and gives it an ideal shape.
They are manufactured in a dental laboratory by high-pressure hot pressing of a polymer mass. The result is durable, dense pads that withstand high mechanical stress and resist food.
The treatment process includes several stages:
- Examination of the oral cavity, diagnostics, choice of correction method, material and colour of onlays.
- Preparation: debridement of damaged teeth and surfaces grinding for the base placement 0.3-0.5 mm deep.
- Making impressions (creating 3D models) for the laboratory.
- Overlay manufacturing.
- Fitting and fixation of composite veneers in the patient’s oral cavity.
The treatment process requires at least two visits to the dentist and takes 3-14 days, depending on the condition of the client’s teeth.
Composite materials used in dentistry to manufacture aesthetic onlays contain several components mixed in specific proportions. These include:
- polymeric inhibitor;
- inorganic filler;
- organic matrix,
- catalysts;
- dyes.
Restoration materials allow you to select the desired shade accurately. They have a low degree of shrinkage, high mechanical strength, and are abrasion resistant. In addition, they are characterised by excellent adhesion to dentin, have an anti-cavity effect, are chemically neutral, and are hypoallergenic.
Doctors use several varieties of multicomponent materials:
- standard – with one-, two- or three-colour concepts for selecting the desired shade;
- composites suitable for the restoration of chewing or anterior teeth, as well as universal ones;
- cured by chemical, light, thermal or combined methods;
- traditional soft, liquid (fluid), condensable;
- with different particle sizes (micro (up to 0.4 microns), mini (up to 5 microns), macro (up to 45 microns), combined).
Dentists and patients prefer products from well-known brands: Filtek, Charisma, Tetric, Gradia, Estelite, Esthetic, Spectrum, Herculite and others.
Disadvantages: Teeth After Removing Veneers
The disadvantages worth mentioning are the following:
- short service life;
- low strength to mechanical loads;
- gradual discolouration due to food stains and tobacco smoke.
It is worth preferring high-quality materials to make composite veneers last long, preserve their properties, and avoid discomfort.
Trust the manufacturing of overlays to experienced professionals, follow the dentist’s recommendations for oral care, and make sure you visit your dentist for check-ups on time.
In our Clinic of Aesthetic Dentistry, experienced orthodontists fix composite veneers. They are always ready to help make your smile perfect.
Tooth Alignment Using Veneers
One of the common reasons for composite veneer placement is to align the teeth.
The procedure can correct minor bite defects:
- slight rotation;
- diastema (the gap between incisors);
- sparse teeth;
- short teeth.
Often, patients are not ready to wait several years for the result of wearing braces, do not want to feel discomfort, sacrifice aesthetics, and prefer to align their teeth quickly in 1-2 visits.
Distal, mesial, deep bite and other severe anomalies are not eliminated with overlays. Instead, orthodontic plates, braces, and surgery are used for correction. At the final stage of treatment, it is allowed to use aesthetic plates to enhance the positive effect of the treatment. Before correcting the bite, it is necessary to perform diagnostics and modelling using impressions or 3D visualisation.
Aesthetic prosthetics give an excellent result with overlays for tooth enamel hypoplasia (partial or complete absence of enamel). With such a pathology, the surface of the canines and incisors looks uneven, with cavities, stains and grooves. Cosmetic overlays help to quickly and effectively solve the problem.
The main conditions for successfully aligning teeth with composite veneers are the right choice of clinic and dentist, a thorough examination, the use of high-quality materials and professional fillings. This ensures the long life of the onlays, no complications and excellent cosmetic effect.
