Biaxial flexural strength of CAD/CAM ceramics.
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 ...
Effect of ceramic shade on the degree of conversion of a dual-cure resin cement analyzed by FTIR
Objectives: The aim of this research was to evaluate the degree of monomer conversion of different resin cement shades when photocured under different feldspathic ceramic shades. The photocuring time was also evaluated as ...
Ceramic repair without hydrofluoric acid
Purpose: To evaluate the bond strength between composite resin and feldspathic ceramic following repair protocols with and without hydrofluoric acid and aging by thermocycling. Materials and Methods: Forty-eight glass ...
Porous Ceramic Materials From Polysiloxane-Clay Composites
(Soc Brasileira QuimicaSao PauloBrasil, 2014)
Electrical properties of a composite of Polyurethane and ferroelectric ceramics
Ferroelectric ceramic particles based on lead titanate zirconate (PZT) were dispersed in a polymer matrix based on castor oil. After the poling process, the pyroelectric activity of this composite was measured using a ...
Microstructure of ceramics TiO2 obtained by protein consolidation
Porous ceramics can be produced by adding starch (corn, potato) and protein (animal or vegetable) to raw material as pore forming element. In this study, titanium dioxide ceramics were formed by vegetable protein consolidation. ...
Effect of different impression methods and ceramic materials on adaptation of inlaysEfeito de diferentes métodos de moldagem e materiais cerâmicos na adaptação de inlays
Objective: The aim of this study was to evaluate the internal and marginal adaptation of inlays fabricated from different types of impressions (conventional and digital) and different ceramics (feldspathic and lithium ...
