This book was released on 2012-12-06 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biodegradable, polymer-based systems are playing an increasingly pivotal role in tissue engineering replacement and regeneration. This type of biology-driven materials science is slated to be one of the key research areas of the 21st century. The following aspects are crucial: the development of adequate human cell culture to produce the tissues in adequate polymer scaffold materials; the development of culture technology with which human tissues can be grown ex-vivo in 3D polymer matrices; the development of material technology for producing the degradable, 3D matrices, having mechanical properties similar to natural tissue. In addressing these and similar problems, the book contains chapters on biodegradable polymers, polymeric biomaterials, surface modification for controlling cell-material interactions, scaffold design and processing, biomimetic coatings, biocompatibility evaluation, tissue engineering constructs, cell isolation, characterisation and culture, and controlled release of bioactive agents.

Download or read book Development of Biodegradable Implants for Use in Maxillofacial Surgery written by Benjamin S. Kelley and published by . This book was released on 1986 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maxillofacial injury requiring open or closed reduction is a frequent result of modern military conflicts. Traditional reduction methodologies involve the use of metallic plates, screws, and wires, along with their associated problems. Therefore, biodegradable fixation appliances, which should provide initial rigidity but then gradually weaken so that newly-forming bone is exercised, have been investigated. COmposite plates made from poly (DL-lactide) and reinforced with calcium metaphosphate (CMP) fibers are very strong, but they weaken rapidly when exposed to an aqueous environment because of a disruption of the interface between the reinforcing fibers and polymer matrix. Coating the plates with a hydrophobic, biodegradable film slows this weakening, but more protection is required. Smaller-diameter fibers and better fiber wetting by the matrix also result in more stable composites, but even nonbiodegradable polymers reinforced with CMP fibers rapidly lose strength in saline. Methods to protect the fiber/polymer interface from fluid attack, such as fiber coatings, alternative bioresorbable glasses, and improved composite fabrication techniques have been investigated. Keywords: Resorbable implants; Boneplate; Fracture fixation; Calcium metaphosphate. (AW).

Different failure mechanisms such as corrosion, fatigue, and wear will be reviewed, together with experimental techniques for monitoring them, either in vitro or in vivo. Procedures for implant retrieval and analysis will be presented. A variety of biomaterials (stainless steels, titanium and its alloys, nitinol, magnesium alloys, polyethylene, biodegradable polymers, silicone gel, hydrogels, calcium phosphates) and medical devices (orthopedic and dental implants, stents, heart valves, breast implants) will be analyzed in detail. The book will serve as a broad reference source for graduate students and researchers studying biomedicine, corrosion, surface science, and electrochemistry.

Download or read book Biodegradable Fracture Fixation Plates for Use in Maxillofacial Surgery written by RA. Casper and published by . This book was released on 1985 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Partially biodegradable composites were prepared from a biodegradable polyester, reinforced with carbon or ceramic fibers, and evaluated for their potential use in fixing mandibular fractures resulting from maxillofacial injuries. The composites, made using a lamination technique, were found to possess the strength and rigidity of bone. Their incubation in phosphate-buffered saline at 37°C resulted in the gradual reduction of both flexural strength and flexural modulus of the samples. Reductions in strength and rigidity were paralleled by commensurate reductions in the viscosity of the matrix resin. Evaluation of the model system demonstrated the potential for improved management of fracture wounds using biodegradable materials.

Abstract: In fracture management with open reduction and internal fixation with metallic implant, secondary procedure of removal of implant is often required. Such procedure causes additional surgical risks to patients, including anaesthetic risks, wound infection, bone infection, soft tissue adhesion and joint stiffness. The procedure is also costly to the patient and society. If the fixation implant is self-resorbable, the need for secondary surgery will be completely eliminated and the social resources can be saved. Making use of the corrosion process, metals can be developed into new generation of resorbable (or biocorrodible, biodegradable) implants. An ideal bioresorbable orthopaedic implant should provide adequate mechanical support that matches the bone healing process. The implant should resorb progressively as the bone heals. Many current resorbable materials are biomechanically inferior to conventional metallic implants. Magnesium based alloys are popularly studied because of their mechanical properties and biocompatibility. Implants made of magnesium based alloy are expected to resorb in the human body with no harmful effect. The major research challenge is to identify an alloy that performs satisfactorily in the following aspects: biocompatibility, degradation rate, hydrogen gas formation (gas product from the reaction between Mg and water), and mechanical strength. In addition, there is no standard evaluation method for the biodegradable alloys. It is because the interaction between the degradable implants and the physiological environment is too complicated to mimic. The in vitro and the in vivo results often mismatch. This research involved the design and the tests of three Mg based alloys. Zinc (Zn) and manganese (Mn) were chosen as the alloying elements for corrosion resistance and mechanical enhancement. Mg-1Zn-1Mn, Mg-3Zn-1Mn, Mg-5Zn-1Mn (in wt.%) were developed and compared. The study was divided into three parts: material characterization, in vitro studies, and in vivo (animal) studies. The SEM/EDX confirmed that the surface properties of the alloys were consistent after the surface treatment. From the mechanical test, the yield strengths and the densities of the alloys were found to be close to that of the natural bones. The theoretical calculation showed that the amount of Mn determined the threshold implant mass of the test alloys. The hydrogen evolution test showed that the Mg-1Zn-1Mn was the least corrodible. The elution test showed that the Mg-1Zn-1Mn was the least cytotoxic and the cytotoxicity was affected by the pH changes brought by the alloys. The live cell imaging captured the interaction between the alloys and the cells. The subcutaneous implantation showed that the Mg-3Zn-1Mn formed the smallest gas pocket. In the six-month femoral implantation study (Mg-3Zn-1Mn excluded), the Mg-1Zn-1Mn showed the least volume loss and the steadiest degradation behaviour. It was also found to associate with better bone responses. Concluding from all the results, the Mg-1Zn-1Mn demonstrated better potential to become biodegradable orthopaedic products. This work evaluated the potentials of the new alloys and proposed some suggestions for the mismatch results. Moreover, quantitative investigation of biomechanical properties, long term degradation behaviour, and toxicity are recommended to be carried out in the future.
