Review of Antibacterial Activity of Titanium-Based Implants’ Surfaces Fabricated by Micro-Arc Oxidation
Ti and its alloys are the most commonly used materials for biomedical applications. However, bacterial infection after implant placement is still one of the significant rising complications. Therefore, the application of the antimicrobial agents into implant surfaces to prevent implant-associated infection has attracted lots of attentions. Scientific papers have shown that inorganic antibacteri...
متن کاملShot Peening of a Titanium Alloy for Medical Implant Applications with Ziirconia Shot
Shot peening with steel shot followed by a cleaning process with glass beads is commonly used as surface finish in the production of modular hip endoprostheses. The induced compressive residual stresses increase the resistance against fatigue and fretting fatigue. The surface roughness can be adjusted in a range that enhances the physiological acceptance I compatibility of monolithic ~rnplants....
متن کاملSurface characteristics of and in vitro behavior of osteoblast-like cells on titanium with nanotopography prepared by high-energy shot peening
BACKGROUND AND METHODS Commercial pure titanium with nanotopography was prepared via a high-energy shot-peening (HESP) technique. The surface characteristics were evaluated, and the preliminary cell responses to the nanotopographical surface were investigated. RESULTS The nanotopographical surface layer on titanium was successfully processed by HESP. The average nanoscale grains were approxim...
متن کاملMicro-Arc Oxidation Enhances the Blood Compatibility of Ultrafine-Grained Pure Titanium
Ultrafine-grained pure titanium prepared by equal-channel angular pressing has favorable mechanical performance and does not contain alloy elements that are toxic to the human body. It has potential clinical value in applications such as cardiac valve prostheses, vascular stents, and hip prostheses. To overcome the material's inherent thrombogenicity, surface-coating modification is a crucial p...
متن کاملHydroxyapaptite Layer Formation on Titanium Alloys Surface Using Micro-arc Oxidation
In recent years, research on titanium and its alloys had increased significantly for hard tissue replacement and dental applications due to their excellent mechanical properties such as high strength to weight ratio, low density and biocompatibility. However, there are some surface originated problems associated with titanium (Ti): poor implant fixation, lack of osseoconductivity, wear and corr...
