Mg-Zr-Sr alloys as biodegradable implant materials.
Novel Mg-Zr-Sr alloys have recently been developed for use as biodegradable implant materials. The Mg-Zr-Sr alloys were prepared by diluting Mg-Zr and Mg-Sr master alloys with pure Mg. The impact of Zr and Sr on the mechanical and biological properties has been thoroughly examined. The microstructures and mechanical properties of the alloys were characterized using optical microscopy, X-ray dif...
متن کاملMagnesium, Zinc and Iron Alloys for Medical Applications in Biodegradable Implants
Biodegradable materials are developed for designing temporary medical implants, like fixation devices for fractured bones or stents. At present, polymeric biomaterials such as poly-lactic acid (PLA) are currently used in these applications. The disadvantage of polymers is a low mechanical strength, hardness and wear resistance that is the main limitation for the use in load-bearing implants. Fo...
متن کاملBiodegradable 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 کاملSynthetic biodegradable polymers as orthopedic devices.
Polymer scientists, working closely with those in the device and medical fields, have made tremendous advances over the past 30 years in the use of synthetic materials in the body. In this article we will focus on properties of biodegradable polymers which make them ideally suited for orthopedic applications where a permanent implant is not desired. The materials with the greatest history of us...
