Ceramic micro-stereolithography (mSL) was recently introduced in the fabrication of complex 3D ceramic microstructures. Light scattering is found as an important factor in the mSL of ceramics. In this work, the Monte Carlo ray tracing method is employed to investigate the in¯uences of the important materials properties on the scattering during the ceramic mSL. It is found that the scattering is...

Lightweight ceramic-metal combinations are one option for advanced vehicle and other structural applications. These structures can require the fabrication of large area arrays of ceramic tiles on a metallic backing. However, the process of fabricating a combination of lightweight ceramics and metals is complicated by the need to bond these very dissimilar materials together. For severe applicat...

In this paper, the biocompatibility of dental implant materials is discussed in the context of both the mechanical characteristics of the materials and the type of surface presented to the surrounding tissues. The proper functioning of the implant depends on whether it possesses the strength necessary to withstand loading within the expected range, with other properties such as elongation being...

QDT 2005 1 he restoration of missing or compromised tooth structure requires dental materials that offer toothlike esthetics, functionality, biocompatibility, and longevity. Silica-based ceramics (eg, feldspathic porcelain) offer all of these necessities and are the materials of choice for esthetic all-ceramic restorations (eg, laminate veneers, ceramic inlays and onlays, and full-coverage jack...

The indications for and composition of today's dental ceramic materials serve as the basis for determining the appropriate class of ceramics to use for a given case. By understanding the classifications, composition, and characteristics of the latest all-ceramic materials, which are presented in this article in order of most to least conservative, dentists and laboratory technicians can best de...

The presence of glass-like contaminants inside waste glass products, usually resulting from both industrial and differentiated urban waste collection, has greatly increased in recent years, due to the introduction to the market of a large amount of goods manufactured from ceramic glass. The presence of contaminants in the glass recycling streams reduces product quality and increases production ...

Glass-ceramic materials were developed from gabbro including MgO and Al2O3 additives. Heat treatments for phase transformation from glassy matrix to glass-ceramic were carried out at 1000 ◦C for 3 h. X-ray di raction studies conducted on the glass-ceramic samples revealed that the phases formed in the glass-ceramics were cordierite, anorthite, diopsitic augite, forsterite and andesine. Glass an...

In the ceramic materials acoustic emission (AE) is associated with a rapid elastic energy release due to the formation and expansion of cracks, which causes generation and propagation of the elastic wave. AE pulses measurement allows monitoring of internal stresses changes and the development of macroand micro-cracks in ceramic materials, and that in turn allows us to evaluate the time to failu...

As dentistry continues to evolve, new technologies and materials are continually being offered to the dental profession. Throughout the years restorative trends and techniques have come and gone. Some material developments have transformed the face of esthetic dentistry, while other initial concepts have already phased out and disappeared. Today, all-ceramic restorations continue to grow in the...

Different studies available in literature regarding the analysis of all-ceramic restorations failures, investigated several parameters involved on the tooth structure restoration complex, in order to improve clinical performances. Some of the parameters, like the framework design, are technique-sensitive during the manufacturing of the restorations and can easily influence the failure rates and...
