2009年4月1日 · For multilayered discs, Hsueh et al.’s rigorous solutions were obtained by (i) finding the correlation between monolayered and multilayered discs subjected to biaxial …
Analyses of multilayered dental ceramics subjected to biaxial …
2006年5月1日 · It is shown that the solutions for multilayered discs subjected to biaxial flexure tests can be obtained from the existing solutions for monolayered systems by replacing the …
Thermal residual stresses in bilayered, trilayered and graded …
2017年3月1日 · Layered ceramic systems are usually hit by residual thermal stresses created during cooling from high processing temperature. The purpose of this study was to determine …
bilayered discs. A total of 60 discs with 0.3, 0.4, and 0.5 mm thickness were obtained from a fully sintered zirconia block. A 1.5-mm thick layer of veneer porcelain was fired on the zirconia …
The bending stress distribution in bilayered and graded zirconia …
In bilayered discs, the maximum tensile stress decreased while the stress mismatch (at the interface) increased with the porcelain layer thickness. The optimized balance between both …
Comparative study of in vitro release and mucoadhesivity of …
2014年3月12日 · Discs made of bilayered were physically stable for more than 50-97.50 min in 0.1 M HCl at 37 ° C, and exhibited higher mucoadhesion on the gastric mucosa (2.70-3.99%) …
The effect of zirconia thickness on the biaxial flexural strength of ...
The aim of this study was to assess the effect of zirconia core thickness on the biaxial flexural strength values of zirconia-porcelain bilayered discs. A total of 60 discs with 0.3, 0.4, and 0.5 …
Triamcinolone acetonide (TA) is a glucocorticoid commonly used for the treatment of oral lichen planus (OLP). To avoid extensive first pass metabolism and to prolong the duration of its …
