The installation of ceramic veneers is a complex and responsible process that requires maximum attention and scrupulousness from the dentist and laboratory technician. Therefore, in order for ceramic veneers to last for many years, and the smile to become harmonious and natural, it is necessary to conduct a thorough diagnosis of the proper functioning of the dental apparatus before dental restoration.
Preparation of teeth for veneers
The preparation of teeth for ceramic veneers is carried out in order to prepare the minimum sufficient space for ceramic restoration, which provides maximum preservation of dental tissue.
The amount and thickness of space to obtain mechanical strength and aesthetic quality varies from 0.2 to 0.5 mm, and depends on the diagnosis and treatment plan.
To determine the scope of work and ensure the quality of dental procedures, the doctor considers the following:
- diagnoses the dental apparatus;
- specifies the thickness of tooth tissue required to achieve structural strength;
- Sets the desired color and shape of the veneer.
Installation of temporary veneers Mock-UP
Making and installing temporary Mock-UP veneers allows the patient to see what permanent dentures will look like in the future.
To do this, the dentist:
- removes the patient’s teeth;
- performs wax or computer modeling;
- receives casts of both jaws, according to which the technician makes plaster models in the laboratory.
Wax modeling Wax-Up using the obtained gypsum models leads to the creation of samples of ceramic veneers that meet the wishes of patients and have an exclusive option.
The result in the form of a special plastic construction Mock-UP is ground with a marker drill to determine the depth of tooth preparation. In some cases, dissection is not required.
The doctor shows the patient a plaster and wax model to compare what the situation is now and what will be the result of treatment.
After completing all corrections and obtaining consent, Wax-Up is transferred to the oral cavity, and the size and shape of permanent restorations will exactly match the temporary ones.
10-14 days for the manufacture of ceramic veneers
In modern dental laboratories, in order to achieve the maximum density of the ceramic veneer to the tooth, technicians use a microscope.
The process of making ceramic veneers can be done in two ways:
- by layer-by-layer application of porcelain mass one after another, alternately baking. In this way, the technician achieves the required transparency and hue;
- by casting at high temperature and pressure.
Complete anatomical contours can be reproduced by adding dentin mass with minimal adjustment and smoothing with a brush.
As the cutter shades and special effects of the veneers should look varied and lively, clear boundaries around the individual layers should be avoided.
Proper use of appropriate materials and accessories, as well as the exact implementation of the manufacturer’s instructions, allow you to create ceramic veneers with impressive accuracy.
Trying on and fixing ceramic veneers
Fitting is required for the final fixation of ceramic veneers. It is carried out by fixing the veneer plate on the enamel, with pre-applied fitting mass. These manipulations are performed to certify the correct selection of shape and color.
Once the identity and accuracy of the shape and color of the veneers are established, the dentist prepares for installation. To do this, he treats the inner surface of the veneer with hydrofluoric acid to form micropores. Then sandblasting to improve the adhesive properties of the ceramic plate, and washed with water.
FThe next stage is the preparation of the tooth surface by dissecting and treating the crown with phosphoric acid of 37% concentration, which forms a relief and improves adhesion. Acid residues are washed away with water.
Direct installation to the ceramic veneer is carried out after fitting and washing the fitting mass. The inner surface of the veneer is degreased and dried, and the fixing material (composite cement) is applied to the tooth, distributing it evenly over the surface. The prepared veneer is installed on the tooth by light pressure for better adhesion, polymerized with a UV lamp and finished to obtain a perfectly smooth surface.
The need to constantly sleep with a hood to get used to ceramic veneers
Due to the individual characteristics of patients, dentists recommend sleeping with a cap on the teeth after installing ceramic veneers. This recommendation is also desirable for healthy teeth, because it protects during sleep from unintentional abrasion caused by experiencing possible stressful situations during the day.
Caps are made of transparent material, and they do not change diction. The schedule of wearing is determined by the doctor. The effect of the cap is mild – it does not cause pain or discomfort.
Do not forget that the caps are effective in correcting the bite, align the teeth and allow you to get a good smile.
