are used extensively in orthopedic implants because of their excellent biocompatibility,mechanical properties and corrosion resistance. However,titanium-based implant materials face many severe complications,such as implant loosening due to poor osseointegration and bacterial infections,which may lead to implant failure. Hence,preparing a biomaterial surface,which enhances the interactions......
of solution volume to sample surface area should be adopted based on the real implant situation, and the dynamic corrosion is preferred. As to the evaluation methodology of corrosion rate, different... by observing the time-dependent change in the metallic volume of the remaining implant [68]. The computation equation is as follows: ......
alloy for surgical implants were directly observed by in situ scanning electron microscopy(SEM).The effect of phase transformations on deformation-induced martensitic transformation accompanying......
" name="ChDivSummary">Titanium rods were processed into implant samples with cavity and groove in which was filled with HAP/β-TCP porous osteoconduction composite materials in order to increase the mechanical stability of the implant in vivo.The phase compositions of the composite was characterized by X-ray diffraction (XRD) and scanning electron microscopy(SEM).Histological evaluation showed......
="ChDivSummary">A new concept for development of metallic biomaterials is proposed in this article,i.e.,a certain bio-function can be realized for a metal implant through continuous release of a designed bio-functional metal element from surface of the metal implant in the body environment.This creative idea has been verified to be possible by several different in vitro and in vivo experimental......
生物可降解塑料PHB的压电性能及在骨移植中的应用 蒋凌飞1,胡平1 (1.清华大学化工系,北京,100084) 摘要:综述了PHB及其共聚物和复合材料的压电性能及其在骨头生长中的可能应用. 关键词:聚-β-羟基丁酸酯; β-羟基丁酸共聚物; 压电性能; 骨移植材料; [全文内容正在添加中] ......
implant in order to improve osseointegration. Based on the above, a novel antimicrobial dental implant material, Ti-Cu alloy, was treated with SLA, to combine chemical design(Cu addition... importantly, in vivo studies also demonstrated that Ti-Cu/SLA implants had wonderful biological performance. In the osseointegration model, Ti-Cu/SLA implant promoted osseointegration via increasing peri......
that reveals the best wear and corrosion resistances as compared with the substrate. Hence, this coating will perform best for orthopaedic implant material enhancement.
