Aseptic loosening (bone resorption) and infection are some of the main causes leading to the failure of orthopaedic implants. Between other causes, aseptic loosening is attributed to stress shielding and/or to the over-activation of osteoclasts (bone resorbing cells) induced by the release of wear debris by the implant. Infection is due to the colonization of the surface of the implant by…
Alloys of the Ti-Nb system are promising in the orthopedic area, due to the fact that niobium has a minimum dissolution rate, which contributes to low cytotoxicity, and is also a beta-stabilizing element, acting in decrease of the elastic modulus. On the other hand, the surface of an orthopedic implant strongly interferes in the osseointegration process, due to its direct interaction with…
Ti and your alloys are commonly used in the biomedical area, mainly as cardiovascular, orthopedical and dental implants. Its applications occur due your favorable properties, as high mechanical strength and density ratio, relative low Young's modulus, excellent corrosion and wear resistance, further good biocompatibility. The development of new metallic biomaterials has searched for Ti a…
Titanium and titanium alloys are widely used for the production of dental implants due to their good mechanical properties, excellent biological behavior and good corrosion resistance. However, some implant failures are still reported in the literature. This way, it is essential to develop new titanium surfaces with improved properties to achieve a more efficient behavior in the intra-ora…
Total hip arthroplasty has become more and more a common surgery mainly due to the ageing population. As a result, the development of new materials for this type of prosthesis is an issue of extreme importance, aiming at greater durability and efficiency. Currently, the hip prosthesis is modular, divided into four components. One of these components is the femoral stem, commonly made of t…
Infection and tribocorrosion degradation are among the main complications by prosthesis-associated factors, leading to the failure of orthopedic implants. In order to solve this issue, the implant material can be functionalized by micro-arc oxidation (MAO), an effective technique to produce porous coatings incorporated with bioactive elements. According to recent works, improved tribologi…
