In order to achieve maximum results in an attempt to repeat the natural beauty of natural teeth, we use the so-called ceramic veneers. Veneer (veneer), translated from English, means “facing”, the outer layer. Thus, we recreate the lost outer layer of tooth enamel, which has undergone wear, chips or uneven abrasion, we use this technology to change the color of teeth, slightly change their shape and position. Ceramics is the most suitable material for restoring or replacing the natural enamel of a tooth, it is ceramics that have the physicochemical and optical properties that are closest to those of natural teeth.
Due to the absence of any frame (metal or zirconium), ceramic veneers have a stunning aesthetics, transmitting and scattering light, like natural tooth tissues. But not only excellent aesthetics is a determining factor in the choice of material. In addition to this, ceramics, due to the possibility of its special preparation (etching and silanization), can be glued to the surface of a natural tooth (like a composite filling), such adhesive fixation ensures reliable adhesion of ceramics and tooth tissues, so that they become one. From this feature follows the following most important advantage of adhesive ceramics over cermets and zirconia crowns. This, of course, is the possibility of minimally invasive preparation of teeth (and sometimes even the absence of the need for preparation of teeth). By preserving as many natural tooth tissues as possible, we provide guaranteed long-term functioning of your teeth. The more tissue we remove, the worse the prognosis. Imagine how long a live tooth will function with a small restoration, and how long the tooth will last, in which the root canals were treated, a pin is installed, and in addition to this, the tooth is also “sharpened” under a full crown. The answer is obvious to us.
Due to its low invasiveness, we also use adhesive ceramics for the posterior teeth in order to preserve as much of our own tooth tissues as possible. If the ceramic inlay (ceramic veneer for the chewing tooth) is correctly made and fixed using a rabberdam, then it perfectly withstands the chewing load, despite the apparent fragility of the ceramic. It is the adhesion force and hardness of the ceramic that allows it to successfully simulate the natural tooth enamel and withstand loads during chewing.
So, the main advantages are indicated: the maximum possible aesthetics, adhesive fixation and minimal intervention, but what about the disadvantages? Ideal technologies do not exist, therefore ceramic veneers have some limitations. Firstly, it is their cost. The best is the enemy of the good and the most provincial and sophisticated treatment methods will always be expensive, not just because they are advanced and complex, but because the process of creating ceramic veneers is a unique, time-consuming, lengthy process that requires the participation of not only an experienced, trained doctor -Dentist, but also a talented dental technician. Ceramic veneers are the quintessence of science and art in dentistry. The next limitation of ceramic veneers is at the same time their “strength”, adhesion, namely, the adhesion force of ceramics to tooth tissues. Ceramic adheres to tooth enamel very well, we know this by looking at clinical cases where ceramic veneers were glued to enamel 20 years ago and more. But if the tooth is badly damaged and the enamel is practically or completely absent, then there may be problems with adhesive fixation, so in this case ceramic veneers may not be the best solution. And the last limitation that can be attributed to ceramic veneers is the complexity of repairs in some cases.
Before starting aesthetic treatment, we conduct a special diagnosis, the so-called “Digital Smile Design”. This diagnosis consists of photographing, identifying problems and rendering tasks for the dental technician in the computer program. After that, we get the impressions of the teeth, send to the laboratory, where the dental technician on a plaster model repeats our task in wax (restores the shape of the teeth) and we, after receiving these models, can transfer this form to the patient’s teeth and take a series of photos again, evaluating the result . And note, this is all BEFORE the treatment starts, when the teeth are not yet touched and there is an opportunity to change the shape and size of future restorations, even their number, using the prototype! We don’t prepare teeth at random, but polish exactly the amount of tissue that is needed to make and fix the veneer. The wax modeling, which the technician has already done, helps us with this, we use the key to prepare the teeth.
