Abstract Body: With the introduction of monolithic zirconia, interesting and high-strength materials have become available for the production of all-ceramic dental restorations even without a supplementary veneering layer. The development of highly translucent zirconia generations and the progress in the field of state-of-the-art CAD/CAM technologies, which enabled virtual design and milling of fully anatomical structures from the high-performance material zirconia, have made a decisive contribution to the attractiveness and feasibility of these prosthetic materials. The focus is on the possibilities and limitations of the different zirconia generations discussing for example the influence of hardness and wear resistance or options to use monolithic zirconia due to its high strength even for minimally-invasive preparations or special indications e.g. implants or abutments. The opportunities how the restoration is adapted and polished or pretreated and cemented contribute are discussed to guarantee the clinical success of the restoration.
