Effect of pH variation on the subcritical crack growth parameters of glassy matrix ceramics
(2019-01-01)
The goals of our study were to calculate the subcritical crack growth (SCG) parameters of two veneering ceramics stored in water or Streptococcus mutans (S. mutans) biofilm and remineralizing medium, with indentation flaws. ...
Effect of alternative sonochemical treatment on zirconia surface and bond strength with veneering ceramic
(Elsevier B.V., 2020-02-01)
The morphological characterization of sonochemical treatment on bond strength of Y-TZP/veneer ceramic was evaluated. The surface topography and roughness were analyzed by Confocal Laser Scanning Microscopy, Atomic Force ...
Neural tool condition estimation in the grinding of advanced ceramics
(Ieee-inst Electrical Electronics Engineers Inc, 2015-01-01)
Ceramic parts are increasingly replacing metal parts due to their excellent physical, chemical and mechanical properties, however they also make them difficult to manufacture by traditional machining methods. The developments ...
Biaxial flexural strength of CAD/CAM ceramics.
(2011-06-01)
Aim of the study was to evaluate the biaxial flexural strength of ceramics processed using the Cerec inLab system. The hypothesis was that the flexural strength would be influenced by the type of ceramic. Ten samples (ISO ...
Influence of resin cement thickness and temperature variation on mechanical behavior of dental ceramic fragment restoration
(2019-03-12)
To evaluate the stress behavior of ceramic fragment restoration, varying the thickness of the cement layer and intraoral temperature variation. A solid model of a upper lateral incisor was obtained and a defect at enamel ...
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 ...
Valorization of sugarcane bagasse ash: Producing glass-ceramic materials
(Elsevier B.V., 2014-02-15)
Some aluminosilicates, for example mullite and wollastonite, are very important in the ceramic and construction industries. The most significant glass-ceramic for building applications has wollastonite as the main crystal ...
Flexural Strength of Glass-Infiltrated Zirconia/Alumina-Based Ceramics and Feldspathic Veneering Porcelains
(Wiley-Blackwell, 2009-07-01)
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 ...
Liquid foam templates associated with the sol-gel process for production of zirconia ceramic foams
(2013-08-14)
The unique properties of ceramic foams enable their use in a variety of applications. This work investigated the effects of different parameters on the production of zirconia ceramic foam using the sol-gel process associated ...
Silica coating on alumina ceramic: comparison of three chairside air-abrasion devices working for different times and distances.
(2011-03-01)
This study evaluated, by scanning electron microscope (SEM) and EDS, the effect of different strategies for silica coating (sandblasters, time and distance) of a glass-infiltrated ceramic (In-Ceram Alumina). Forty-one ...
