The evolution of computerized systems for the production of dental restorations associated with the development of new microstructures for ceramic materials has caused an important change in the clinical workflow of dentists and technicians, as well as in the treatment options offered to patients. New microstructures have also been developed by the industry to offer ceramic and composite materials with optimized properties, that is, good mechanical properties, appropriate wear behavior and acceptable aesthetic characteristics. The purpose of this literature review is to discuss the main advantages and disadvantages of the new ceramic systems and processing methods. The manuscript is divided into five parts: I) monolithic zirconia restorations; II) multilayer dental prostheses; III) new glass-ceramics; IV) ceramic infiltrated by polymer; and V) new processing technologies. Dental ceramics and processing technologies have evolved significantly in the past ten years, with most of the evolution related to new microstructures and CAD-CAM methods. In addition, a trend towards the use of monolithic restorations has changed the way physicians produce all-ceramic dental prostheses, since more aesthetic restorations in several layers, unfortunately, are more prone to chipping or delamination. Composite materials processed via CAD-CAM have become an interesting option, as they have intermediate properties between ceramics and polymers and are more easily milled and polished.
