CATHODIC BEHAVIOUR of ANODIZED TITANIUM IN SIMULATED PHYSIOLOGICAL CONDITIONS
(Plapiqui(uns-conicet), 2011-07-01)
In the present work, anodic oxide films on titanium specimens were formed in physiological solution under potentiostatic condition. The immediate- to short-term changes in the oxide film were studied by open-circuit potential ...
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 ...
Porous titanium scaffolds produced by powder metallurgy for biomedical applications
(2008-07-01)
Porous titanium scaffolds are promising materials for biomedical applications such as prosthetic anchors, fillers and bone reconstruction. This study evaluated the bone/titanium interface of scaffolds with interconnected ...
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 ...
Osteogenesis-inducing calcium phosphate nanoparticle precursors applied to titanium surfaces
(2013-05-20)
This study investigated the effects of the morphology and physicochemical properties of calcium phosphate (CaP) nanoparticles on osteogenesis. Two types of CaP nanoparticles were compared, namely amorphous calcium phosphate ...
Titanium in Dentistry: Historical development, state of the art and future perspectives
(2013-06-01)
Titanium is a metallic element known by several attractive characteristics, such as biocompatibility, excellent corrosion resistance and high mechanical resistance. It is widely used in Dentistry, with high success rates, ...
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 ...
Adsorption of chromium(VI) by titanium(IV) oxide coated on a silica gel surface
(Royal Soc Chemistry, 1991-03-01)
Titanium(IV) oxide, coated on the surface of silica gel (surface area, 308 m2 g-1; amount of Ti(IV) per gram of modified silica gel, 1.8 x 10(-3) mol), was used to adsorb CrO4(2-) ions from acidic solutions. The exchange ...
A comparison of molar root canal preparation using stainless-steel and nickel-titanium instruments
(1999-12-01)
Fifty-four extracted human mandibular molars were embedded and sectioned at two levels. The reassembled mesial root canals were prepared with stainless-steel hand K-files (Flexofiles) and either Nitiflex or Mity nickel-titanium ...
Growth of Calcium Phosphate Using Chemically Treated Titanium Oxide Nanotubes
(Trans Tech Publications Ltd, 2011-01-01)
Many materials with different surfaces have been developed for dental and orthopedics implants. Among the various materials for implants, titanium and bioactive ones such as calcium phosphates and hydroxyapatite, are widely ...
