Factors to Achieve Aesthetics in All-Ceramic Restorations
(Lippincott Williams & Wilkins, 2010-11-01)
The demand for aesthetic restorations has increased during the last years. Dental ceramics are a successful alternative for some cases because of aesthetics and biocompatibility. Therefore, the aim of this literature review ...
Flexural Strength of Glass-Infiltrated Zirconia/Alumina-Based Ceramics and Feldspathic Veneering Porcelains
Purpose: To compare the flexural strength of two glass-infiltrated high-strength ceramics and two veneering glass-ceramics.Materials and Methods: Four ceramic materials were tested: two glass-infiltrated high-strength ...
Ceramic Material Porous Structure Prepared Using Pore-Forming Additives
Porous ceramic materials exhibit high permeability, specific surface, and thermal shock resistance, and therefore they may be used successfully in the production of filters, membranes, and as a substrate for catalytic ...
Interdisciplinary project applied to engineering education: construction of a miniature ceramic industry
(Int Council Materials Education, 2015-04-01)
The greatest challenge of undergraduate engineering courses is to encourage creativity, cooperation with other students, teamwork, and motivation in the first years of their courses. While students have little or no contact ...
Piezoelectric composite film for acoustic emission detection
The continuous technological advances require materials with properties that conventional material cannot display. Material property combinations are being the focus to the development of composite materials, which are ...
Bioactivity of leucite containing glass-ceramics using natural raw materials
(Universidad Federal de Sao Carlos, 2014-09)
Glass compositions were carefully prepared, using natural quartz and potassium feldspar as a part of the starting raw materials. The solids were prepared so as to have theoretical stoichiometric leucite and 45S5 Bioglass ...
Surface agents' influence on the flexural strength of bilaminated ceramics
The objective of this study was to evaluate the influence of different surface agents on the flexural strength of a ceramic system. Eighty bar-shaped specimens of zirconia were divided into four groups according to the ...
Comparison of two bond strength testing methodologies for bilayered all-ceramics
