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 کاملBiodegradable Materials and Metallic Implants—A Review
Recent progress made in biomaterials and their clinical applications is well known. In the last five decades, great advances have been made in the field of biomaterials, including ceramics, glasses, polymers, composites, glass-ceramics and metal alloys. A variety of bioimplants are currently used in either one of the aforesaid forms. Some of these materials are designed to degrade or to be reso...
متن کاملStarch-based completely biodegradable polymer materials
Starch is a natural polymer which possesses many unique properties and some shortcoming simultaneously. Some synthetic polymers are biodegradable and can be tailor-made easily. Therefore, by combining the individual advantages of starch and synthetic polymers, starch-based completely biodegradable polymers (SCBP) are potential for applications in biomedical and environmental fields. Therefore i...
متن کاملAn introduction to biodegradable materials for tissue engineering applications.
Tissue generation by autogenous cell transplantation is one of the most promising treatment concepts being developed as it eliminates problems of donor site scarcity, immune rejection and pathogen transfer. Cultured cells are seeded onto a three-dimensional biocompatible scaffold that will slowly degrade and resorb as the soft and hard structures grow and assimilate in vitro and/or in vivo. The...
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...
