Biodegradable Composite Materials as Bone Regenerative Implants
Bioresorbable polymers do not provide sufficient load-bearing support within the body as they do not possess the mechanical properties required to fixate bone [1]. Structural implants rely on durable materials such as metal alloys and ceramics which exceed the modulus of the parent bone tissue approximately tenfold. Since bone structure constantly adjusts to local conditions, this tends to weak...
متن کاملA biodegradable polymer-based coating to control the performance of magnesium alloy orthopaedic implants.
Magnesium and its alloys may potentially be applied as degradable metallic materials in orthopaedic implantations due to their degradability and resemblance to human cortical bone. However, the high corrosion rate and accumulation of hydrogen gas upon degradation hinders its clinical application. In this study, we adopt a new approach to control the corrosion rate by coating a controllable poly...
متن کاملBiocompatibility of magnesium-zinc alloy in biodegradable orthopedic implants.
In this study, magnesium-zinc (Mg-Zn) alloy was investigated as a biodegradable orthopedic implant. MC3T3-E1 cell attachment, mineralization and osteogenic-specific mRNA expression were assessed for as measurements of the in vitro biocompatibility of Mg-Zn alloy. In vivo degradation of the Mg-Zn alloy and the accompanying new bone formation in the femoral marrow cavity were analyzed by scanning...
متن کاملCorrosion Resistance Enhancement of AZ91 Magnesium Alloy Using Ni-P Interlayer and Electrophoretic Deposited 3YSZ Coating
The zirconia stabilized by 3mol % Y2O3 (3YSZ) was applied onto the surface of the magnesium alloy AZ91D using electrophoretic deposition (EPD) from a non- aqueous solution. A Ni-P interlayer between the substrate and YSZ coating was also prepared by electroless plating. Finally, coatings were heat treated in control atmosphere at 400 °C. The preparation, microstructure and corrosion resistance ...
