For years, porcelain veneers have been associated with cosmetic dentistry. These faces can change the color, shape, position or size of the teeth. In addition, gaps and intermittent spaces disappear or decrease.
Today, porcelain veneers are made digitally in special dental laboratories after the initial impression. Precise models of your mouth are scanned and then the veneers are designed, modified and manufactured with the help of computers (CAD/CAM Dentistry, Computer Aided Designed/Computer Aided Manufactured).
Obviously, for their construction, the teeth are slightly prepared (0.3mm) in order to create the appropriate space for their placement. Of course, in cases where a tooth needs to be moved forward and into the dental arch or when a small tooth becomes larger, preparation is usually not considered necessary.
Stages in the construction of porcelain veneers
Examination, evaluation, design
The most important step in the whole process is the initial assignment, evaluation and design of the smile reconstruction – smile makeover by the dentist so that you are informed about all the relevant options and make the most ideal decision for your new smile!
Relevant x-rays are considered necessary in the initial evaluation, revealing problems that may not be seen before construction while study models help in proper design on a case-by-case basis. Analog or digital models of the final design are placed in the mouth after duplication in order to present the image of the final result before the construction. The procedure is called motivational mock up.
Local anesthesia and tooth preparation
After you decide to improve your smile and agree with the original design, the treatment usually starts with the use of local anesthetics and the dentist then makes a predetermined reduction of the face (front) surface to create the appropriate face support substrate (0.3 – 0.7 mm).
Once the preparation is complete, an impression of the preparations and the mouth is obtained using a special tray or digitally ensuring a more accurate recording.
Due to health reasons, dental sensitivity, aesthetics and not only, during the construction of permanent restorations, they impose the use of temporary veneers made of acrylic material, which in shape resemble that of the final ones, so that you and your friendly environment can evaluate them. This step is especially important as it allows you to indicate any changes you wish and all corrections are made individually. Then, usually 1 week later, after adapting to the new design, impressions of the final result are taken again. The procedure is called mock up and allows you to adjust the final result in relation to your own aesthetics before the lab proceeds to permanent construction.
Once the final veneers are made, the dentist tests them on the prepared teeth so that they fit perfectly and do not interfere with chewing. Special temporary powder is used before permanent cementation to check the final color of the veneers on the teeth, giving maximum aesthetics. Throughout construction and placement, safety and security are ensured in relation to the final result.
The final stage involves permanent cementation of the veneers using high-tech cementing systems. The strength of the veneer in part is due to its perfect fit but mainly to the strong bonding between it and the special cementing system. The boundaries are then cleared and it is ensured that the patient can make easy use of the floss between the teeth.
Smile freely and confidently with your new great smile!
