Abstract: Science and research are continuously advancing and dental technology is not an exception. There is an evolution from traditional to contemporary, and production stages are becoming increasingly automated or computerized. As the trend continues, digitization will become an integral part of contemporary prosthodontics with the probability of most of the procedures being based on digital techniques in the near future. Although in industry they were used for several years, CAD / CAM applications in dentistry have developed only in the 80s. Later new developments have led to the success of contemporary CAD/CAM technologies. They are over 35 today, with an exponential growth in the last 10 years and have following characteristics: similar functional standards as conventional homologues, require long-term studies, acceptable alternative to the equivalents performed conventionally, continuous improvements are made to the user interface, extensive automation and appropriate time saving is an increasing challenge for dental practice. Finite element analyses emerged as a necessity to study the states of tension and deformation in structures with geometric complexity for which analytical calculation models were not operable. Different studies were designed to evaluate all-ceramic CAD/CAM crowns fatigue and strength test methods, which would reproduce clinical failure modes. Interdisciplinary digital methods are in a continuous process optimization and will continue to improve in versatility, accuracy, and cost effectiveness. This work was supported by a grant of the Romanian National Authority for Scientific Research and Innovation CNCS-UEFISCDI, project number PN-II-RU-TE-2014-4-0476.
