Prostheses made without taking into account the anatomical and physiological features of gum tissues have an adverse effect on the tissues of the prosthetic bed and increase atrophic processes. One of the main clinical tasks in dentistry is the full restoration of chewing function due to the high quality of manufactured dentures. Computer programs and technologies have changed and simplified human life in various branches of life and activities. In recent time, digital technologies began to actively apply in restoration dentistry. If before the manufacture of prosthetics was engaged in manual, starting with measurements, designing and completing casting, but now modeling and manufacturing are automatic processes controlled by the computer. And this is all due to the development of CAD \ CAM technology. CAD \ CAM Technologies is automated method of manufacturing orthopedic constructions. CAD \ CAM systems compared to the traditional methods of manufacturing orthopedic constructs excluding mistakes of the human factor, which allows to achieve faster and accurate manufacturing of prostheses. The CAD \ CAM technology ensures high accuracy, functionality and detail of the tooth and the bite of the patient, allows visualization and optimizing design and aesthetic aspects of the crown before it is made. Conclusion. The use of CAD\CAM technologies in dentistry has such advantages as: maximum automation of production, high accuracy and functionality of modeling and manufacturing structures taking into account the anatomical features of the dentoalveolar system, avoiding the gag reflex in patients, maximum quality of execution and increased patient comfort, significant time savings, avoiding the ingress of impression materials into the respiratory tract. Thus, after analyzing the presented material, we can say that orthopedic structures made using CAD\CAM technologies fully meet the requirements, as well as the most optimal in the "quality-time"ratio. CAD\CAM technology allows you to produce orthopedic structures taking into account the individual features of the patient's Anatomy. Thus, this method allows you to solve many clinical problems related to prosthetics, individualize prostheses as much as possible, and make them more convenient and comfortable.
