The evolution of computerized systems for the production of dental restorations associated to the development of novel microstructures for ceramic materials has caused an important change in the clinical workflow for dentists and technicians, as well as in the treatment options offered to patients. New microstructures have also been developed by the industry in order to offer ceramic and composite materials with optimized properties, i.e., good mechanical properties, appropriate wear behavior and acceptable aesthetic characteristics. The objective of this literature review is to discuss the main advantages and disadvantages of the new ceramic systems and processing methods. The manuscript is divided in five parts: I) monolithic zirconia restorations; II) multilayered dental prostheses; III) new glass-ceramics; IV) polymer infiltrated ceramics; and V) novel processing technologies. Dental ceramics and processing technologies have evolved significantly in the past ten years, with most of the evolution being related to new microstructures and CAD-CAM methods. In addition, a trend towards the use of monolithic restorations has changed the way clinicians produce all-ceramic dental prostheses, since the more aesthetic multilayered restorations 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.

“…Although framework design and firing protocols were optimized, the cohesive fracture (chipping) and delamination of the veneering ceramic is the most common clinical complication, whilst core fracture was reported to be very infrequent (Della Bona & Kelly 2008;Land & Hopp 2010;Guess et al 2011;Marchack et al 2011;Zarone et al 2011;Ferrari et al 2015a;Ferrari et al 2015b). Consequently, fabrication strategies and techniques to eliminate the veneering ceramic were developed, till the introduction of Computer Aided Design-Computer Aided Manufacturing (CAD-CAM) monolithic materials, just like zirconia and lithium disilicate (Rojas-Vizcaya 2011; Beuer et al 2012).…”

“…To date, very few laboratory data about the mechanical predictability of monolithic zirconia crowns are available in the literature, particularly for very thin restorations (Beuer et al 2009;Choi et al 2012;Schmitter et al 2012), as well as the validation of their clinical performances in the oral environment (Sailer et al 2009;Marchack et al 2011;Ferrari et al 2015a). Previous in vitro investigations showed that monolithic zirconia SCs exhibited fracture loads higher than those of layered zirconia restorations (Dhima et al 2013;Sun et al 2014;Lan et al 2015).…”

“…Associated with these developments of the concept that if ceramic chipping could be avoided and the wear of ceramics and antagonists could be reduced [4][5][6][7][8] , the application of the veneering porcelain has been decreasing in the clinical situation. TZP could be used for fabricating high-strength monolithic restorations 9,10) and might be indicated, especially in posterior regions. It was reported that opaque TZP reduced the wear of antagonists such as human enamel 1,5,7,11) .…”

Wear performance of bovine tooth enamel against translucent tetragonal zirconia polycrystals after different surface treatments

et al. 2014

The wear performances of bovine tooth enamel (BTE) against translucent tetragonal zirconia polycrystals (TZP) compared to that of feldspar porcelain and the influence of surface treatments of translucent TZP were investigated by the two-body wear test. Translucent TZP and feldspar porcelain were used as hemisphere abrader specimens with a radius of curvature of 5 mm; flat BTE surfaces were used as substrate specimens. The cross-sectional area of the worn surfaces of the substrates and the wear volume of the antagonist abraders were measured. Surface roughness, hardness and coefficient of friction as well as SEM observations and EPMA analyses were also performed to investigate the underlying mechanism of wear. The results suggested that BTE is less susceptible to wear when translucent TZP is used as the antagonist in contrast to the use of feldspar porcelain, and that surface treatment of the TZP abraders significantly influenced the wear of BTE substrates.
