Biodegradable Magnesium Alloys: A Review of Material Development and Applications.
Magnesium based alloys possess a natural ability to biodegrade due to corrosion when placed within aqueous substances, which is promising for cardiovascular and orthopedic medical device applications. These materials can serve as a temporary scaffold when placed in vivo, which is desirable for treatments when temporary supportive structures are required to assist in the wound healing process. T...
متن کاملSecurity assessment of magnesium alloys used as biodegradable implant material.
The security risk of magnesium alloys used as biodegradable implant material was evaluated in this study. Dose-response assessment was conducted by using toxicological data from authoritative public health agencies (World Health Organization) and assuming 1~3 years of uniform corrosion. Through modification calculation, the tolerable corrosion rate of biodegradable magnesium alloys in vivo was ...
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 کاملMg-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 کاملBiodegradable Materials for Bone Repair and Tissue Engineering Applications
This review discusses and summarizes the recent developments and advances in the use of biodegradable materials for bone repair purposes. The choice between using degradable and non-degradable devices for orthopedic and maxillofacial applications must be carefully weighed. Traditional biodegradable devices for osteosynthesis have been successful in low or mild load bearing applications. However...
