“…In accordance with previous investigations (Nordhal et al 2015), the results of the present analysis suggested the possibility to reduce crown thickness when fabricating monolithic Y-TZP crowns, reducing the invasiveness of the preparation and saving a valuable amount of dental tissues (Nordhal et al 2015). However, it is not possible to apply laboratory information directly to clinical recommendations, since the clinical scenario is never completely simulated in in vitro tests (Anusavice et al 2007).…”

“…Although the mechanical properties of zirconia exceed those of many metals, the manufacturersÕ guidelines suggest a minimum core thickness of 0.5 mm to avoid fractures (Conrad et al 2007;Zarone et al 2011;Wang et al 2014;Ferrari et al 2014;Ferrari et al 2015a;Ferrari et al 2015b;Lan et al 2015;Nakamura et al 2015;Nordhal et al 2015).…”

New dental materials are often introduced into the market and especially in the current practice, without a basic understanding of their clinical performance because long-term controlled clinical trials are required, which are both time consuming and expensive. Ceramic materials are known for their relatively high fracture resistance and improved aesthetics, but britleness remains a concern. The stressed areas of the materials are key factors for the failure analysis, and numerical simulations may play an important role in the understanding of the behavior of all-ceramic restorations. Simulation-based medicine and the development of complex computer models of biological structures are becoming ubiquitous for advancing biomedical engineering and clinical research. The studies have to be focused on the analysis of all-ceramic restorations failures, investigating several parameters involved in the tooth structure-restoration complex, in order to improve clinical performances. The experiments have to be conducted and interpreted reported to the britle behavior of ceramic systems. Varied simulation methods are promising to assess the biomechanical behavior of all-ceramic systems, and irst principal stress criterion is an alternative for ceramic materials investigations. The development of well-designed experiments could be useful to help to predict the clinical behavior of these new allceramic restorative techniques and materials.

“…Although clinical trials reported successful outcomes for zirconia-based prostheses, chipping of the layering porcelain has been identified as their most important potential limitation [5][6][7] . Approaches to avoid chipping have been introduced, including customization of zirconia frameworks to provide even and appropriate porcelain thickness 8) , sintering of a machine-milled lithium disilicate veneer onto the zirconia framework 9) , use of monolithic zirconia restorations that do not include veneer 10) , and layering of composite materials to the zirconia framework 11,12) . The use of monolithic zirconia restorations has expanded rapidly because of the reduced chipping risk of veneer, lower cost and production time, and diminished preparation depth 13) .…”

Effect of framework design on fracture load after thermal cycling and mechanical loading of implant-supported zirconia-based prostheses

This study evaluated the effect of zirconia framework design on fracture load of implant-supported zirconia-based prostheses after thermal cycling and mechanical loading. Three different zirconia framework designs were investigated: uniform-thickness (UNI), anatomic (ANA), and supported anatomic (SUP) designs. Each framework was layered with feldspathic porcelain (ZAC group) or indirect composite material (ZIC group). The specimens then underwent fracture load testing after thermal cycling and cyclic loading. In the ZAC group, mean fracture load was significantly lower for UNI design specimens than for the other framework designs. In the ZIC group, there was no significant difference in mean fracture load between ANA design specimens and either UNI or SUP design specimens. To improve fracture resistance of implant-supported zirconia-based prostheses after artificial aging, uniformly thick layering material and appropriate lingual support with zirconia frameworks should be provided.
