Modern dental healthcare is unthinkable without the use of biocompatible materials. They must have the necessary mechanical properties to ensure the strength of dental structures, as well as be as acceptable as possible by the human body. In recent years, there has been an increase in the application of zirconium dioxide (ZrO2) material to metal ceramics in the manufacture of dental crowns, bridges and others. This has its natural continuation of the evolution of dental materials, which significantly improve human health not only in the oral area but also in complex, where the goal is to minimize the external contact of biological tissue with certain metal components. The present study shows the application of zirconium in the development of crowns on dental implants. Technological working hours are optimized. The process is followed in detail, highlighting important points that accompany the practical part of making the dental crown through the use of modern technologies in design. To objectively present the information in the study, a set of photographic material is presented, visualizing in detail important moments in the production of the zirconium crown.

Modern society is increasingly using ICT technologies to transfer information quickly. In addition to the purely technological advantages of IT tools, they enable the recipients of information data to be ultimately facilitated in their operational activities. On the other hand, data transfer, when it comes to transferring files with specific information, is a serious issue that concerns both available technological resources and security. This report aims to explore the current technological capabilities for the transfer of digital information containing banking, financial and other data, to be maximum protected from unauthorized or malicious users. Also into question are conventional methods of transmitting digital data via email or cloud. Open source software provides the possibility of reliable encryption and protection: Money Manager Ex, Tor Browser and OnionShare. In the present study, specific advantages of realizing the transfer of digital data from the point of transmission to the final recipient are presented.
