“…Johansson et al reported that translucent TZP shows high strength, supporting the results of this study 27) . The fact that the Zpex specimens showed the same level of strength as conventional TZ3YB suggests that Zpex can be used clinically.…”

“…Ting et al reported that a TZP of 1.0 mm thickness showed the same level of fracture load as metal-ceramic crowns 31) . Johansson et al reported that the fracture load of a TZP crown with an occlusal surface thickness of 1.8 mm was 2,700 N or more 27) . Furthermore, under the biaxial flexural test in this study, the fracture load of 1.0 mm-thick translucent TZP can estimate the 600 N that is equivalent value of the average biaxial flexural strength of the same TZP with 1,060 MPa.…”

This study aims to investigate the effectiveness of monolithic translucent TZP with different colors and porcelain-layered TZP by evaluating their colors and strengths. Different mixing ratios of Zpex to Zpex-Yellow as translucent TZP, conventional opaque TZP (TZ-3YB-E) (Tosoh, Tokyo) as a control, and veneering porcelain (CERABIEN ZR, body porcelain, Noritake, Tokyo) with shade A3 as a typical shade. Disk-shaped specimens of 13 mm diameter and 1.5 mm thickness were prepared. These specimens were observed under reflected and transmitted light, and the translucency parameter (TP) values were measured. Strength was also evaluated with flexural strength in a biaxial bending test. The TP values of the monolithic TZP, Zpex100>Zpex70>Zpex50>TZ3YB, were larger in this order. The flexural strength of all the monolithic TZP showed approximately 1,000 MPa. It is suggested that colored translucent TZP is clinically useful when used as monolithic restorations.

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.
