Sintering temperature accuracy and its effect on ... ScienceDirect
1. Introduction. Since the early 1990 s, yttriastabilized zirconia (YSZ) has become the stateoftheart allceramic material for dental reconstructions [1].Development since then has focused on improving aesthetics towards higher translucency, achieved mainly by increasing the yttria content and changing the sintering time and temperature.

Highly transparent Cedoped yttria stabilized zirconia ceramics with ...
Red cerium doped 8 mol% yttria stabilized zirconia (Cedoped 8YSZ) transparent ceramics were prepared by the twostep sintering method using commercial powders as raw ceramics after presintering at 1300 °C for 2 h and hot isostatic pressing (HIP) posttreatment at 1700 °C for 3 h showed a high inline transmittance and a large redness due to the 4f5d transition absorption of ...
Translucency and flexural strength of translucent zirconia ceramics ...
Lithium disilicate was the most translucent and yet the weakest material, whereas highstrength zirconia was the most opaque ceramic and the strongest. Katana UTML had the highest translucency but was weakest among translucent and highstrength zirconia materials. Overall, translucency was negatively correlated with biaxial flexural strength.

Wear Behavior of Different Generations of Zirconia: Present ... Hindawi
Enamel Wear. In vivo studies on enamel wear opposing a monolithic zirconia crown found that average vertical wear of the enamel antagonist was considerably higher than the contralateral enamel controls at the same time interval [3, 74, 75].A higher wear rate during the first 6 months suggested an initial runningin period followed by more steady wear afterward.
