Effects of Dextrose and Lipopolysaccharide on the Corrosion Behavior of a Ti-6Al-4V Alloy with a Smooth Surface or Treated with Double-Acid-Etching
(PLOS ONE, 2014-03-26) [Artigo]
Diabetes and infections are associated with a high risk of implant failure. However, the effects of such conditions on the electrochemical stability of titanium materials remain unclear. This study evaluated the corrosion ...
Effect of bleaching agents and soft drink on titanium surface topography
(Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2014-01-01) [Artigo]
The effects of carbamide peroxide, hydrogen peroxide and cola soft drink on the topographic modifications of commercially-pure titanium (CP-Ti) and Ti-6Al-4V were investigated. Ti discs were divided into 18 groups (n=4) ...
The influence of bone quality on the biomechanical behavior of full-arch implant-supported fixed prostheses
(Materials Science & Engineering C-materials For Biological Applications, 2014-04-01) [Artigo]
We evaluated the influence of bone tissue type on stress distribution in full-arch implant-supported fixed prostheses using a three-dimensional finite element analysis. Stresses in cortical and trabecular bones were also ...
Corrosion kinetics and topography analysis of Ti-6Al-4V alloy subjected to different mouthwash solutions
(Materials Science & Engineering C-materials For Biological Applications, 2014-10-01) [Artigo]
This study evaluated the corrosion kinetics and surface topography of Ti-6Al-4V alloy exposed to mouthwash solutions (0.12% chlorhexidine digluconate, 0.053% cetylpyridinium chloride and 3% hydrogen peroxide) compared to ...
Evaluation of Torque Maintenance of Abutment and Cylinder Screws With Morse Taper Implants
(Journal of Craniofacial Surgery, 2012-11-01) [Artigo]
The screw loosening of implant-supported prostheses is a common mechanical failure and is related to several factors as insertion torque and preload. The aim of this study was to evaluate the torque maintenance of retention ...
