Clinical Fit of Monolithic Zirconia Single Crowns

The International Journal of Prosthodontics, 2018
To analyze the clinical fit of monolithic zirconia single crowns (MZSCs) in a prospective cohort study.A total of 30 posterior teeth were restored with MZSCs. Silicone replicas were made to measure the clinical fit using a stereomicroscope. Measurements were conducted at 17 points per crown at the marginal and occlusal surfaces.The mean clinical fit ...

Optical properties of monolithic zirconia fabricated with nanoparticle jetting.

The Journal of Prosthetic Dentistry
Excellent 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 ...

Synthesis of zirconia monoliths for chromatographic separations

Journal of Chromatography A, 2006
The aim of this work is to join the advantages of two different kinds of stationary phases: monolithic columns and zirconia-based supports. On the one hand, silica monolithic columns allow a higher efficiency with a lower back-pressure than traditional packed columns.
