Comparison between sandblasted acid-etched and oxidized titanium dental implants: in vivo study
(MDPI, 2019-07-03)
The surface modifications of titanium dental implants play important roles in the
enhancement of osseointegration. The objective of the present study was to test two di erent
implant surface treatments ...
Direct extrusion of individually encapsulated endothelial and smooth muscle cells mimicking blood vessel structures and vascular native cell alignment
(IOP Science, 2020)
Cardiovascular diseases (CVDs) are considered the principal cause of worldwide death, being atherosclerosis the main etiology. Up to now, the predominant treatment for CVDs has been bypass surgery from ...
Comparison of the superelasticity of different nickel–titanium orthodontic archwires and the loss of their properties by heat treatment
(Springer Nature, 2016)
The aim of this work is to describe and compare mechanical properties of eight widely used nickel–titanium orthodontic wires under uniform testing conditions and to determine the influence of the heat ...
Effects of different undersizing site preparations on implant stability
(MDPI, 2020)
As immediate loading protocols are becoming more frequent, the primary stability of implants has become an essential criterion for the osseointegration of dental implants. Based on this, the objective ...
In vitro corrosion behavior of lingual orthodontic archwires
(Hindawi Publishing Corporation, 2011)
To investigate the in vitro electrochemical corrosive behavior of archwires used in lingual orthodontics and the effects on the phase transition temperatures. Materials and Methods. Six different types ...
New bactericide orthodonthic archwire: NiTi with silver nanoparticles
(MDPI, 2020)
A potential new bactericide treatment for NiTi orthodontic archwires based in the electrodeposition of silver nanoparticles on the surface was studied. Twenty-five archwires were treated by electrodeposition, ...
Porous titanium-hydroxyapatite composite coating obtained on titanium by cold gas spray with high bond strength for biomedical applications
(Elsevier, 2019-04-24)
The lack of bioactivity of titanium (Ti) is one of the main drawbacks for its application in biomedical implants since it can considerable reduce its osseointegration capacities. One strategy to overcome ...
Wear in two cases of ceramic on ceramic total hip arthroplasty after 30 years follow up
(Biomedical Research Network, 2018)
Background: Ceramic-on-ceramic (CoC) bearings have been in use in total hip replacement (THR) for more than 40 years, with excellent long-term survivorship but concerns over the ceramic-on-ceramic ...
Mechanical and microstructural characterization of new nickel-free low modulus beta-type titanium wires during thermomechanical treatments
(Elsevier, 2015-06-11)
NiTi alloy is the only practical shape memory alloy (SMA) in biomedical use because of its excellent mechanical stability and functionality. However, it is estimated that between 4.5% and 28.5% of the ...
RE-irradiation of silver nanoparticles obtained by laser ablation in water and assessment of their antibacterial effect
(Elsevier, 2018-12-20)
The rapid evolution of resistant bacteria is a huge problem in medicine because makes the treatment of infections more and more difficult. The bactericidal properties of noble metal nanoparticles could ...
