Clinical justification of the use of digital technologies in prosthetics of patients with complete absence of tee; [Клиническое обоснование применения цифровых технологий при протезировании пациентов с полным отсутствием зубов]

This article describes modern methods for the manufacture of complete removable dentures. Digital technologies allow optimal treatment of patients with complete absence of teeth in the upper and lower jaws. Additive technologies make it possible to produce good quality temporary prostheses. While with the help of subtractive technologies it is possible to obtain final prostheses. Aim - the main purpose of this study is to demonstrate the possibilities and benefits of digital technologies on the example of clinical cases. Materials and methods. The description of methods for obtaining prostheses using additive and subtractive technologies is given. The method developed by us for the manufacture of temporary and final removable dentures was demonstrated. Using a verticulator allows you to achieve accurate positioning of the teeth in the basis of the prosthesis, which eliminates possible inaccuracies associated with the human factor. Results. Two clinical cases are presented. In the first clinical case, the manufacture of an immediate prosthesis using additive technologies was demonstrated. In the second clinical case, the manufacture of a complete removable denture using subtractive technologies was demonstrated. To bind the milled parts of the prosthesis, a verticulator was used, which makes it possible to accurately match and monolithically unite the structures of the prosthesis. Conclusion. Digital technologies make it possible to obtain high-quality prostheses, eliminating human errors and inaccuracies, as well as speed up the procedure for obtaining prostheses and significantly reduce the cost of resources spent on obtaining prostheses made using 3D-printing from an economic point of view. © 2022 Clinical Dentistry (Russia).
