Introduction: Due to modern technologies of fixed prosthetics and ceramics, we tend to fixed prosthodontics, with which we can achieve the natural look of the tooth most efficiently. In order to achieve long-term fixed care, we must take care of the cervical part of the coating and its effect on parodontium. Purpose: The purpose of the diploma work is to show various possible relationships, shapes and positions of the cervical part of the coating to parodontium, highlight the advantages and disadvantages of various cervical stairs and which factors influence the performance of fixed prosthodontic care in dependence of the cervical part of the coating to the parodontium. Methods: Work methods include a review of domestic and foreign professional literature and the production of a practical product in a dental laboratory. Results: In the diploma work, we described and presented all the factors that are related to the cervical step and its effect on parodontics, which influence the performance of the fixed prosthetic anchor. We produced a classic metal-ceramic coating on teeth 14 and 26, metal-ceramic coating with digital technology CAD / CAM milling CrCo frame on tooth 14 and metal-ceramic coating with digital CAD / CAM technology selective laser melting of the frame on the tooth 26. Full-ceramic coatings were made from stabilized zirconium oxide (YTZP) according to the CAD / CAM technique and by the pressing and painting technology of the full-ceramic coating, both on the tooth 21. The manufacturing processes are described and documented. Discussion and conclusion: With modern technologies, the cervical barriers are more precise, and with the development of dental ceramics, it interacts with high esthetics and the appearance of a natural tooth. Full-ceramic coatings are slowly replacing metal-ceramic coatings due to their performance, esthetics and mechanical properties. As metal-ceramic as full-ceramic coatings can be indicated both above and below the margin of the free gum until the coating damages or irritates the biological width. Metal-ceramic coatings due to poorer esthetics are not recommended in the visible field, while there are no obstacles in the case of full-ceramic coatings.
