Review: titanium and titanium alloy applications in medicine
Titanium may be considered a relatively new engineering material. It was discovered much later than the other commonly used metals, its commercial application starting in the late 1940s. Its usage as an implant material began in the 1960s, despite the fact that titanium exhibits superior corrosion resistance and tissue acceptance when compared with stainless steels and Cr-Co-based alloys. This ...

Molecular interactions of degradable and non-degradable polymers with hydroxyapatite influence mechanics of polymer-hydroxyapatite nanocomposite biomaterials
Implant materials composed of hard and soft phases (composite materials) have shown much promise for total bone replacement. Interfacial interactions between the components in these composite biomaterials affect the overall mechanical response. Here, the role of interfacial interactions on the load deformation behaviour of soft phase (polymer) have been analysed using constant velocity Steered ...

What can Niobium be used for
Niobium is special because its high level of corrosion resistance is achieved at a relatively low weight. In the chemical industry, niobium is a high-quality acid and liquid metal corrosion resistant material that can be used in cooking machines heaters and coolers. Based on its high transition temperature, niobium is the perfect material for superconducting cables and magnets. Based on its high ...

The effect of mixing technique on fatigue of bone cement when stress concentrations are present
Mixing techniques used to reduce porosity in bone cement demonstrate large improvements in fatigue behaviour in test specimens, but do not appear to reduce the rate of loosening of implants in vivo. We examined data showing the effect of notches on fatigue strength and found, surprisingly, that notches with low stress-concentration factors (Kt Keywords: mixing technique, fatigue strength, bone ...

Titanium but not just titanium
Titanium and its alloys have many advantages as surgical implant materials, such as low density, high strength, good toughness, good biocompatibility, non-toxicity, low elastic modulus, good corrosion resistance, and low X-ray absorption rate Etc., thus occupying an increasingly important position in medical metal materials. Titanium and its alloys can be used for the repair and replacement of ...

Susceptibility of ePTFE vascular grafts and bioengineered human acellular vessels to infection
Background: Synthetic expanded polytetrafluorethylene (ePTFE) grafts are routinely used for vascular repair and reconstruction but prone to sustained bacterial infections. Investigational bioengineered human acellular vessels (HAVs) have shown clinical success and may confer lower susceptibility to infection. Here we directly compared the susceptibility of ePTFE grafts and HAV to bacterial ...

Polysaccharides Function as Backbone for Embryonic Osteogenesis
Osteogenesis, or new bone formation, begins in the early stages of embryonic development and continues postnatally until skeletal maturity is reached in early adulthood. Osteogenesis reoccurs in the event of bone trauma, such as a fracture or surgically created defect. Bone mass can also increase in response to chronic weight bearing from daily use or decrease due to a lack of movement or applied ...

Plastic neuronal probes for implantation in cortical and subcortical areas of the rat brain
We discuss the fabrication of flexible implantable probes for recording neuronal activity in the rat brain. We fabricated such probes bearing 12 platinum electrodes, using polyimide as a substrate and SU–8 as an insulation layer. The fabrication process was simplified through the use of laser ablation to define the probe outline. The probes showed not only good mechanical flexibility but also the ...

Applications of the High Polymers in Medical Science
Introduction With the wide application of high polymers, more and more extensive researches on high polymers have been conducted in recent years. Many papers and monographs discussed the important characteristics of high polymers and their important applications in medicine. Macromolecule/high polymers can be used in surgery, suture, orthopedic fixation and tissue repair. They can also be used as ...
