objective: a clinical challenge of using zirconia frameworks is to achieve adequate bond with different substrates. this study aimed to evaluate the effect of bioglass and silica coating of zirconia substrates on microshear bond strength of resin cement to tetragonal zirconia. methods: this laboratory experimental study was conducted on zirconia discs. a total of 120 ytzp zirconia (zirkonzahn) ...

Titanium and zirconia are the biomaterials used in medicine and dentistry for restorations and implants. However, the adhesion of zirconia to other materials is weak. The implant fixation of titanium and zirconia is slow. This is due to the chemical and bio-inertness. The performance can be improved by coating with other materials. This mini review will discuss the coating methods with zirconia...

In this study we report on the development and operational data of a metal-supported solid oxide fuel cell with a thin film electrolyte under varying conditions. The metal-ceramic structure was developed for a mobile auxiliary power unit and offers power densities of 1 W/cm² at 800 °C, as well as robustness under mechanical, thermal and chemical stresses. A dense and thin yttria-doped zirconia ...

A monoclinic zirconia coating with a nanostructural surface was prepared on the Ti-6Al-4V substrate by an atmospheric plasma-spraying technique, and its microstructure and composition, as well as mechanical and biological properties, were investigated to explore potential application as a bioactive coating on bone implants. X-ray diffraction, transmission electron microscopy, scanning electron ...

Resin bonding to zirconia cannot be established from standard methods that are currently utilized in conventional silica-based dental ceramics. The solution-gelatin (sol-gel) process is a well developed silica-coating technique used to modify the surface of nonsilica-based ceramics. Here, we use this technique to improve resin bonding to zirconia, which we compared to zirconia surfaces treated ...
