Titanium (Ti) and Ti-based alloy are widely used in the biomedical field owing to their excellent mechanical compatibility and biocompatibility. However, the bioinert bioactivity and biotribological properties of titanium limit its clinical application in implants. In order to improve the biocompatibility of titanium, we modified its surface with TiOx/TiNx duplex composite films using a new met...
Ti-6Al-4V triply periodic minimal surface (TPMS) structures with biomorphics scaffold designs are expected to be the most promising candidates for many biological applications such as bone implants. Fracture is the main failure mode of Ti-6Al-4V cellular structures at room temperature. However, there is currently less investigation on general analysis about the fracture mechanism of Ti-6Al-4V T...
Total knee replacement implants consisting of a Co-29Cr-6Mo alloy femoral component and a Ti-6Al-4V tibial component are the basis for the additive manufacturing of novel solid, mesh, and foam monoliths using electron beam melting (EBM). Ti-6Al-4V solid prototype microstructures were primarily α-phase acicular platelets while the mesh and foam structures were characterized by α(')-martensite wi...
Cp-Ti is the most common material used for dental implants, but its elastic modulus is around five times higher than that of bone. Recently, promising alloys that add Nb, Ta, Zr and Mo to Ti have been developed. The mechanical properties of these alloys are directly related to its microstructure and the presence of interstitial elements, such as oxygen, carbon, nitrogen and hydrogen. In this st...
To prevent infection in dental implants using photocatalytic activity under visible-light irradiation, the fabrication of Au-added TiO2 layers on Ti substrates and their antibacterial properties were studied. Pure Au Ti–(60, 40) mol%Au alloy films with thicknesses 10–47 nm sputtered onto Ti, followed by thermal oxidation air at 873 K for 1.8 ks to form layers. The against Escherichia coli, cyto...
Additive manufacturing (AM) enables fully dense biomimetic implants in the designed geometries from preferred materials such as titanium and its alloys. Titanium aluminum vanadium (Ti6Al4V) is one of pioneer metal alloys for bone implant applications, however, reasons eliminating toxic effects Ti6Al4V maintaining adequate mechanical strength have increased potential commercially pure (cp-Ti) to...
Recently, the development of ?-titanium (Ti) alloys with a low Young’s modulus as human implants has been trend research in biomedical materials. However, designing by conventional experimental methods is too costly and inefficient. Therefore, it necessary to propose method that can efficiently reliably predict microstructures mechanical properties titanium alloys. In this study, machine learni...
PURPOSE Although the laser has become one of the most commonly used tools for implant dentistry, research is lacking on whether or not the laser causes any changes on the surface of titanium (Ti) implants. The present study analyzed the morphology, composition, crystal structure, and surface roughness changes of machined and anodized Ti surfaces, irradiated with erbium chromium-doped yttrium-sc...
Present work aims at multi-mechanical surface treatment of Ti-6Al-4V based-miniplate implant manufactured by electrical discharge machining (EDM) for biomedical use. Mechanical surface treatment consists of consequent use of ultrasonic cleaning, rotary tumbler polishing, and brushing. Surface layers are analyzed employing scanning electron microscopy and energy dispersive X-ray spectroscopy. Al...
An increasing number of patients receiving radiation therapy have metallic implants such as hip prostheses. Therefore, beams are normally set up to avoid irradiation through the implant; however, this cannot always be accomplished. In such situations, knowledge of the accuracy of the used treatment planning system (TPS) is required. Two algorithms, the pencil beam (PB) and the collapsed cone (C...
