Tribocorrosion behaviour of anodic treated titanium surfaces intended for dental implants
(2013-10-09)
Tribocorrosion plays an important role in the lifetime of metallic implants. Once implanted, biomaterials are subjected to micro-movements in aggressive biological fluids. Titanium is widely used as an implant material ...
Streptococcus mutans attachment on a cast titanium surface
(2009-08-13)
This study examined by means of scanning electron microscopy (SEM), the attachment of Streptococcus mutans and the corrosion of cast commercially pure titanium, used in dental dentures. The sample discs were cast in ...
Avaliação da formação do biofilme de Candida albicans sobre superfície de titânio revestida com hidroxiapatita por meio de microscopia eletrônica de varredura
(2004-12-01)
In this study Candida albicans biofilm formation on the surface of commercially pure titanium (cp-Ti) coated with hydroxyapatite was observed by means of scanning electron microscope. The biofilm was formed after 45 days ...
Influence of a Fluoridated Medium with Different pHs on Commercially Pure Titanium-Based Implants
(Wiley-Blackwell, 2009-02-01)
Purpose: The objective of this study was to assess the influence of a fluoride medium with different pHs on the corrosion resistance of three commercially pure titanium-based dental implant commercial brands, under scanning ...
Effect of thermal treatments on tensile strength of commercially cast pure titanium and Ti-6Al-4V alloys
(2005-08-01)
Heating titanium structures is assumed to relieve tensions induced by the casting process as well as possibly optimizing some mechanical properties. The aim of this investigation was to evaluate the effect of thermal ...
Evaluation of the fretting fatigue behaviour of commercially pure titanium
(Professional Engineering Publishing Ltd, 2007-07-01)
Fretting fatigue occurs when the contact surfaces of two components undergo small oscillatory movement while they are subjected to a clamping force. A cyclic external load gives rise to the early initiation of fatigue ...
Response of rat bone marrow cells to commercially pure titanium submitted to different surface treatments
(Elsevier B.V., 2003-03-01)
Objectives. Alterations in the commercially pure titanium (cpTi) surface may be undertaken to improve its biological properties. The aim of this study is to investigate the biocompatibility of cpTi submitted to different ...
Vickers hardness of cast commercially pure titanium and Ti-6Al-4V alloy submitted to heat treatments
(2006-12-01)
The purpose of this study was to evaluate the effect of heat treatments on the Vickers hardness of commercially pure titanium and Ti-6Al-4V cast alloys. Six-millimeter-diameter cylindrical specimens were cast in a Rematitan ...
Analysis of failed commercially pure titanium dental implants: A scanning electron microscopy and energy-dispersive spectrometer X-ray study
(Amer Acad Periodontology, 2005-07-01)
Background: the failure of osseointegration in oral rehabilitation has gained importance in current literature and in clinical practice. The integration of titanium dental implants in alveolar bone has been partly ascribed ...
What is the role of lipopolysaccharide on the tribocorrosive behavior of titanium?
(Elsevier B.V., 2012-04-01)
In an oral environment, titanium dental implants are exposed to a complex degradation process which is predominantly influenced by the intermittent mechanical events (mastication), continuous exposure to varying chemical ...
