1. Análisis de la forma de onda de señales de Emisión Acústica producida en ensayos de interfaces ceramo-metálicas
ABSTRACT The study of ceramic-metal interface is of special importance in odontology area by the current demand about dental prostheses, so it is very important to be more and more similar to natural teeth and with a long service life. With the aim of assessing in detail the behavior of ceramic-metal interface used in dental restorations systems, in this wor

2. Microstructure and Mechanical Properties of Borided Inconel 625 Superalloy
ABSTRACT The Ni- based superalloy Inconel 625 is extensively used owing to its high strength, excellent fabricability, good weldability and outstanding resistance to high temperature corrosion against aggressive environments. However, despite its unique properties and extensive use, its wear resistance is in some cases unsatisfactory. In this study, Inconel

3. Effect of Metal Primers on Bond Strength of a Composite Resin to Nickel-Chrome Metal Alloy
Resumo Este estudo avaliou os efeitos de três primers para metais e um sistema adesivo multi-mode na resistência da união por cisalhamento (SBS) de um compósito resinoso de baixa viscosidade a uma liga niquel-cromo (Ni-Cr). Noventa placas Ni-Cr foram divididas em 9 grupos (n=10). As superfícies foram jateadas com Al2O3 e condicionadas com três primers

4. Testing electrode suitability for field stimulation of high-threshold biological preparations
IntroductionA problem posed by electrical field (E) stimulation of biological preparations with high excitation threshold is that the E intensity required for excitation is likely to induce water electrolysis at the electrode surface, which can alter the extracellular medium and cause deleterious effects on the cells. In this study, different electrode mater

5. Influence of metal alloy and the profile of coronary stents in patients with multivessel coronary disease
BACKGROUND: In Brazil, despite the recommendations of the Brazilian Society of Hemodynamics and Interventional Cardiology, the National Health System has not yet approved the use of drug-eluting stents. In percutaneous coronary interventions performed in the public and part of the private health care system, bare metal stents are used as the only option. The

7. Desajuste Marginal de Infra-estruturas metálicas de próteses fixas sobre implantes considerando tipos de pilares, materiais e solda a laser / Marginal misfit of metallic structures of total fixed implant supported prosthesis considering abutments, material and laser welding
The adaptation precision of metallic structures to implant abutments is a very questionable subject and the scientific literature lacks about the alloy that shows an adaptation closer to the ideal. This study had the proposal of: evaluating the vertical marginal misfit levels (in μm) using a digital microscope of one-piece and after laser welding metall

8. A study of the correlation between marginal fit and tensions transmitted to implants by one-piece metal castings - a photoelastic analysis. / Estudo da correlação entre adaptação marginal e tensões transmitidas aos implantes por estruturas metálicas fundidas em monobloco - análise fotoelástica.
Obtaining a good marginal fit of the prosthetic components is one of the main obstacles to the success of rehabilitation with implant-supported prostheses. It is not clear, in the literature, which misfit levels are considered clinically acceptable, but it is known that the absence of a perfect and passive fit may cause inadequate tensions on the osseointegr
