Abstract: Computer-aided design/computer-aided manufacturing (CAD/CAM) systems play an increasing role in current dental prosthodontics. Optimizing of dental restorations is one of the key factors of introducing digital technologies in the prosthodontic treatment. During the time a high number of technologies and principles have been developed and led to the success of contemporary CAD/CAM systems. Several aspects of significant technological improvements are the development and application of new type of materials, the development of different scanners, the introduction of virtual articulator softwares and transfer of digitized casts to the virtual articulator, the availability of more efficient milling and 3D printing machines. All these technologies require long-term studies in order to be introduced in dental practice. The major concern in using digital restorations is to increase their strength and reliability. Analyses of the failure evolution can be conducted using mechanical or extended finite element analyses. Reliability analyses methods provide a systematic approach for evaluating dental restorations. The variability and uncertainty of a lot of factors that affect the failure rate of oral prostheses achieved by new digital technologies have to be considered. Additional efforts are necessary for a more accurate reliability and to improve the performance of these restorations further. 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.
