Effect of changes in sintering parameters on monolithic translucent zirconia
Dental Materials, 2014Aim of this study was to evaluate the effect of different sintering parameters on color reproduction, translucency and biaxial flexural strength of monolithic zirconia.Translucent zirconia discs having 15mm diameter, 1mm thickness, and shade A3 were milled and divided according to the sintering temperatures (1460°C, 1530°C, and 1600°C) into three ...

Color Aspect of Monolithic Zirconia Restorations: A Review of the Literature
Journal of Prosthodontics, 2018AbstractMonolithic zirconia restoration is an acceptable treatment option in restorative dentistry and a developing trend in esthetic dentistry. Digital dentistry has simplified fabrication of monolithic zirconia restorations. Zirconia ceramic has introduced an opportunity to achieve both esthetic and mechanical requirements for restorations.

Optical properties of monolithic zirconia fabricated with nanoparticle jetting
The Journal of Prosthetic DentistryExcellent optical properties are essential for esthetic dental materials. However, the translucency and color masking ability of zirconia fabricated with nanoparticle jetting (NPJ), a type of printed zirconia, are unknown.The purpose of this in vitro study was to evaluate the translucency and color masking ability of zirconia fabricated using NPJ.A ...

Crystallization Behaviour of Monolithic Doped Zirconia and Zirconia-Alumina Composite Gels
Transactions of the Indian Ceramic Society, 2001Polymeric monolithic doped zirconia and zirconia-alumina stiff gels (via stable zirconia and zirconia-alumina sols respectively), derived from Zr-n-propoxide, acetyl acetone, aluminium chloride, di-methyl formamide etc with judicious time-temperature-pH selection, have been prepared by controlled hydrolysis and polycondepsation, and subsequently ...
