The effect of adhesive systems on the pullout strength of a fiberglass-reinforced composite post system in bovine teeth
(2005-12-01)
Purpose: To evaluate the pullout strength of a glass fiber-reinforced composite post (glass FRC) cemented with three different adhesive systems and one resin cement. The null hypothesis was that pullout strengths yielded ...
Aproveitamento da fibra de borra de café como material de reforço em compósitos com matriz de resina epóxi preparada a partir de óleo de cozinha usado
(Universidade Federal de Minas GeraisUFMG, 2017-04-28)
The use of natural source materials for the production of biocomposites lead to great interest in industries and researchers due to their low cost, abundance and the fact that they are renewable and biodegradable. In this ...
Do mechanical advantages exist in relining fiber posts with composite prior to its cementation?
(2018-01-01)
Purpose: To evaluate two different techniques for glass fiber-reinforced resin post (FRC) insertion by assessing the stress distribution under polymerization shrinkage or masticatory loading and measuring the pull-out bond ...
Methodology for the analysis of post-tensioned structures using a constitutive serial-parallel rule of mixtures: Large scale non-linear analysis
(Elsevier, 2019-05)
The main purpose of this paper is to develop a reliable method based on a three-dimensional (3D) finite-element (FE) model to simulate the constitutive behaviour of reinforced concrete structures strengthened with ...
Fatigue resistance of bovine teeth restored with resin-bonded fiber posts: Effect of post surface conditioning
(2008-01-01)
This study evaluated the effect of post surface conditioning on the fatigue resistance of bovine teeth restored with resin-bonded fiber-reinforced composite (FRC). Root canals of 20 single-rooted bovine teeth (16 mm long) ...
