Aesthetics is imperative in today's society, so it is not surprising that it is very important for everybody to have a beautiful smile. The planning and implementation of fixed prosthodontics therapy is a real challenge for any clinician because the final work must meet not only functional but also aesthetic requirements as well. The concept of digital design of a smile is relatively new on the market and is based on the analysis of photographs and videos of a patient's smile that help creating the appearance of their future fixed prosthetic replacement in a computer program. That enables better communication between the dentist and the patient, but also between the dentist and the dental technician. The patient is thus enabled to visualize and possibly modify the final therapeutic outcome, thereby making him an active participant in planning. In addition, this method is very fast, accurate and efficient, facilitating all prosthetic rehabilitation and clearly defining its goals, which is a key step for success. In addition to conventional two-dimensional planning, a three-dimensional method of digital smile planning is appearing on the market, which requires the use of an intra or extraoral scanner, a CAD / CAM unit and possibly a 3D printer. Although the experience, skills and knowledge of dental practitioners on aesthetic parameters are crucial in planning and conducting fixed prosthetic therapy, digital smile design greatly simplifies the entire process. However, all methods of digital smile planning require additional training of the dental team, the possession of very expensive equipment and the time and because of thet their implementation is still limited. But by further digitalization and modernization, the prices of the equipment will be lowered, thus enabling the integration of these digital methods into everyday use in dental practice.
