In recent years, the use of zirconia as a high-strength support for all-ceramic restorations has become widely accepted. The failure of zirconia restorations is mainly due to the weakness of veneering porcelain and other factors such as veneering approach. Except conventional hand layering, other methods such as pressing and digital veneering have been recently introduced and used. Meanwhile, t...
A Review of Silorane and Methacrylate Based Composites and Effective Factors on Microleakage of them
Introduction: An important disadvantage of current dental resin composites is their polymerization shrinkage and production of microleakage. This shrinkage can cause tooth sensitivity, marginal discoloration, and secondary caries. The objective of this study was to review the effective factors on microleakage of methacrylate and silorane composites and compare them with each other. This review...
X-ray measurements reveal a crystalline monolayer at the surface of the eutectic liquid Au82Si18, at temperatures above the alloy's melting point. Surface-induced atomic layering, the hallmark of liquid metals, is also found below the crystalline monolayer. The layering depth, however, is threefold greater than that of all liquid metals studied to date. The crystallinity of the surface monolaye...
Abstract With the research of urban historical landscape, its definition has been continuously deepened. The development a city is regarded as result accumulation cultural and natural values in different periods, that is, landscape ‘layering.’ This paper takes dynamic layering process Largo architectural Macau content uses method to take economy, society culture each period internal cause value...
This article reviews recent work on the perception of color in cases where color change leads to scission, or a perceived layering in depth of the visual field into chromatic processes. A model is proposed that predicts under what circumstances a layering in depth is perceived. The model takes into account shift in color and change in contrast; it helps to describe the colors and lightnesses of...
