Nowadays, there is an increasing number of patients who pay more attention to the beauty of their smile and less to the health of their teeth. That is one of the reasons whymany very young patients with completely intact teeth visit the dental offices asking for corrections of the existing deviations in the position, shape or colour of the teeth, looking to get a new, more beautiful smile. Carious lesions, as well as the mechanical damage to hard tooth structures, which include abrasion, erosion, attrition, and dental abfraction, can be the reason why a patient might need fixed prosthodontics. The type of therapy is then chosen based on the degree of destruction. Thanks to the wide range of options provided by fixed prosthodontics, we can help both patients with impaired function, and those who are simply not satisfied with the appearance of their teeth. A number of parameters needs to be taken into account to achieve satisfactory results. These parameters involve the selection of the appropriate colour and shape, which need to suit the physiognomy in order to get the desired harmony. In improving the appearance of the smile, importance must be placed on correcting the placement and shape of the tissues that surround the hard teeth structure andare visible when smiling. Aesthetic dental medicine therefore requires an interdisciplinary approach of almost all branches of dentistry. The two types of procedures used in aesthetic dentistry are preparatory and definitive procedures. Preparatory procedures include orthodontic, periodontal and teeth whitening procedures, while definitive ones include direct or indirect preparation of finite substitutes made of either composite or ceramic material, used on natural teeth or implants. There are three basic ways that we can study facial aesthetics: we can look at the entire face, the relationship between the face structure and the teeth, and the teeth and the smile on their own. The most important element is the facial composition, which affects the patient's perception of a beautiful smile.
