OBJECTIVES The objective of this systematic review was to assess the 5-year survival rates of all-ceramic single crowns and to compare it with the survival rates of metal-ceramic crowns and to describe the incidence of biological and technical complications. METHODS An electronic Medline and Dental Global Publication Research System search complemented by manual searching was conducted to ide...

Yttrium-stabilized zirconia thermal barrier coatings (TBCs) of combustion chambers and piston crowns are used most frequently to increase the chamber temperature internal engine efficiency. The development multilayer metal matrix composite coating is great importance diminish ceramic coating’s brittleness susceptibility degradation providing similar insulation. Our group developing TBCs based o...

the present investigation attempted to develop the ceramic adsorbent media in order to remove the mercury from aqueous phase. two ceramics, akadama volcanic ash soil-ceramic (aceramic) and improved magnesium oxide impregnated akadama volcanic ash soil-ceramic (maceramic) were produced from raw akadama volcanic ash soil by heating process to determine the hg(ii) adsorption capacity. adsorption e...

Over the past 35 years, multiple types of all-ceramic materials have been introduced as an ideal alternative for metal-fused to ceramic. This review covers state-of-the-art development of all-ceramic systems in terms of history, material composition, fabrication technologies, and structural and strength properties. These materials are proved to be ideal in terms of mechanical properties and bio...

Recently introduced FIB/SEM analysis in microscopy seems to provide a high-resolution characterization of the samples by 3D (FIB) cross-sectioning and (SEM) high resolution imaging. The aim of this study was to apply the FIB/SEM and SEM/EDS analysis to the interfaces of a metal-ceramic vs. two zirconia-ceramic systems. Plate samples of three different prosthetic systems were prepared in the den...

The employment of ceramic material simulation design methods can eliminate the disadvantage of traditional ceramic material developing methods of being time-consuming, laborious and high cost. Three simulation methods of artificial neural network, regression analysis and pattern recognition, and their application to ceramic material simulation design were presented in this paper. The problems e...

Based on the exceptional tribological behaviour and on the relatively low biological activity of ceramic particles, Ceramic-on-Ceramic (CoC) total hip arthroplasty (THA) presents significant advantagesCoC bearings decrease wear and osteolysis, the cumulative long-term risk of dislocation, muscle atrophy, and head-neck taper corrosion.However, there are still concerns regarding the best techniqu...
