“…This material design makes it possible to strengthen the 10 mol% ceria-stabilized TZP matrix with 30 vol% Al 2O3. In comparison to Y-TZP, the Ce-TZP/A has a high biaxial flexure strength and toughness, along with satisfied durability in terms of low-temperature aging degradation in various aqueous conditions encountered in dentistry 9,13) . Also, the disk of presintered Ce-TZP/A in this experiment was 98.3 mm in diameter, 14.0 mm in thickness, 1.204 in expansion coefficient.…”

Effects of taper and space settings of telescopic Ce-TZP/A crowns on retentive force and settling

2017

The aim of this study was to investigate the effect of the taper and space setting of using Ce-TZP/A on retentive force and secondary crown settling. The taper were 2°, 4°, and 6°, and the space settings were 0 and 10 μm. The applied loads were 50 and 100 N. The taper had a significant effect on retentive force and settling at both loads (p<0.05). The space settings did not have a significant effect on retentive force or settling at either load (p<0.05). The taper of the telescopic crowns and the load affected the retentive force and the settling.

“…YSZ exhibits superplastic strain rate 34 times faster than submicrometer grained YSZ when measured at the same temperature [36]. However, these properties, that have been demonstrated for several zirconia-based ceramics [47], seem to be not only dependent on the grain size: Domínguez-Rodríguez et al [113], through a critical analysis of the plasticity of two important nanostructured oxide systems, MgO and yttria tetragonal zirconia polycrystals, show how nano-structuring may be a necessary, but not a sufficient condition for superplasticity in ceramics. A complex combination of effects and relationships are shown to modify the superplastic response.…”

Nanostructured Zirconia-Based Ceramics and Composites in Dentistry: A State-of-the-Art Review

et al. 2019

The objective of this paper is to review the current knowledge on the development of nanostructured zirconia-based ceramics and composites suitable for application in dentistry. Isi Web of Science, Science Direct, Scientific.net databases, and Google were searched electronically for the period of 1980 to the present, matching the keywords “nano” with the keywords: “Zirconia, ZrO2, Y-TZP, and dental, dentistry”. A total of 74 papers were found, with the majority coming from Asia, indicating a more active scientific interest on the topic in this geographic area, followed by Europe, South America, and North America. The research shows, even though the scientific activity on nanostructured ceramics was intense in the last fifteen years, the development of fully dense zirconia-based nanoceramics is yet at an initial stage, most of all from the point of view of the clinical applications. It has been demonstrated that nanostructured ceramics can show improved properties because of the reduction of the grain size to the nanoscale. This is also true for zirconia-based nanoceramics, where some improvements in mechanical, optical, as well as resistance in low-temperature degradation have been observed. Potential applications of this class of material in the dental field are discussed, summarizing the results of the latest scientific research.

Bond‐based peridynamics model of 3‐point bend tests of ceramic‐composite interfaces

The need for ceramic composites is increasing over a vast range of industrial applications, including energy and nuclear technology (structural materials for fission and fusion applications); space (thermal shields) or chemical sectors. Current finite element (FE) models are not able to reproduce the aleatory nature of crack generation and propagation through materials and interfaces. To tackle the shortcomings of FE models, a nonlocal bond‐based peridynamics model implemented in the Abaqus FE code has been updated to reproduce the behavior of interfaces between ceramic materials. Two‐ and three‐dimensional simulations have been used to simulate three‐point bend tests for a range of ceramic composites and compared with experiments available in the literature. The model reproduced most of the experimental failure loads, as well as correctly reproducing the failure modes and crack patterns. In particular, the model was able to predict two mechanisms for interface failure, cohesive failure, in which the two materials separate exactly at the interface, and cohesive failure of the substrate, in which a thin layer of the weaker material remains attached to the stronger material and a crack propagates in the weaker material, rather than at the interface. Both failure modes are experimentally observed and still difficult to reproduce with currently available FE simulations.
