Inorganic Biomaterials

This book provides a practical guide to the use and applications of inorganic biomaterials. It begins by introducing the concept of inorganic biomaterials, which includes bioceramics and bioglass. This concept is further extended to hybrid biomaterials consisting of inorganic and organic materials to mimic natural biomaterials. The book goes on to provide the reader with information on biocompatibility, bioactivity and bioresorbability. The concept of the latter is important because of the increasing role resorbable biomaterials are playing in implant applications. The book also introduces a new concept on mechanical compatibility - 'mechacompatibility'. Almost all implant biomaterials employed to date, such as metal and ceramic implants, do not meet this biological requirement as they have far higher modulus than any biomaterials in the body. The practical techniques that are used in the characterization of biomaterials, including chemical, physical, biological, microscopy and mechanical characterization are described. Some specialised techniques are also introduced such as Synchrotron Micro-Computed Tomography (u-CT) and Magnetic Resonance Imaging (MRI). The reader is given important information on new biomaterials development for orthopaedic and other areas, including controlled release technology, hydroxyapatite and hybrid bioresorbable materials. Finally the book provides a guide to regulatory considerations, an area which is often overlooked, but is an important part of R&D and manufacturing of medical materials and devices.

Inorganic biomaterials include materials for e.g. dental restorations, biocompatible materials for orthopedic appliances and bioactive materials. However, inorganic biomaterials are also developed for use in tissue regeneration, e.g. wound healing. These products either consist of crystalline phases, such as Al2O3 or ZrO2, which makes them suitable for use in hip bone replacement or they are composed of tricalcium phosphate and used as resorbable biomaterials. Or, they contain glassy phases, such as BIOGLASS®, and are employed as bioactive biomaterials to bond to living bone. Inorganic biomaterials are also used to develop inorganic – organic composites which are suitable for use as bioactive products or to produce dental filling materials. In general, the development of composites is state of the art. However, it is also a future technology. Biomaterials for dental restorations consist of glassy or crystalline phases. Glass-ceramics represent a special group of inorganic biomaterials for dental restorations. Glass-ceramics are composed of at least one inorganic glassy phase and at least one crystalline phase. These products demonstrate a combination of properties, which include excellent aesthetics and the ability to mimic the optical properties of natural teeth, as well as high strength and toughness. They can be processed using special processing procedures, e.g. machining, moulding and sintering, to fabricate high quality products. Sintered oxide ceramics, such as Al2O3 or ZrO2, are also used for the fabrication of dental restorations. These products can be veneered with other biomaterials, or they can be polished to achieve the best possible surface quality. The manuscripts dealing with inorganic biomaterials should focus on the development of the products, especially on their chemical nature, the phase formation processes and all the details related to their processing. Very important are the mechanisms of phase formation. The reader of the manuscript should understand all of these reactions in detail. As far as application is concerned, it is important to describe the main properties of the developed products based on the valid standards, e.g. the ISO standards. The papers published should show that the products comply with these standards. It is very important to understand the relationship between biomass and biomaterials. This will help young scientists to follow the development of biomaterials with new, unexpected properties. He manuscripts published in "Frontiers" should also focus on the application of the biomaterials. Every manuscript should show the most important application of the material presented. There are different journals that deal with specific product categories, eg "Dental Materials". However, "Frontiers" should allow young scientists to publish their research results using all kinds of inorganic biomaterials. On the other hand, fundamental discussion and analysis of the findings should be encouraged and conclusions about possible applications in the field of medicine and dentistry should be drawn.

This book overviews the underlying chemistry behind the most common and cutting-edge inorganic materials in current use, or approaching use, in vivo.

Biomaterials offer the potential to restore and supplement the function of tissues and organs following injury or disease. The use of inorganic materials in the clinic to date has been widespread, in the form of metallic joint replacements and ceramic dental and bone implants. Exciting new medical applications continue to emerge, enabled by innovative materials for neural interfaces and as anti-fouling agents. The Chemistry of Inorganic Biomaterials overviews the underlying chemistry behind the most common and cutting-edge inorganic materials in current use, or approaching use, in vivo. Framed from the context of the overarching material class/application, it provides a balanced and critical overview of the field by bringing together experts in both the fundamental inorganic and material chemistry, as well as key clinical considerations for biomedical applications. Written in an accessible style, this book will be of interest to advanced undergraduates, postgraduates and researchers in biomaterials, inorganic materials and materials chemistry.

This book provides a contemporary research-led overview of the applications of inorganic materials in biomedicine. It begins with a short introduction summarising key concepts in inorganic materials (layered materials, framework materials etc.), and explaining the need for new materials in medicine. It then discusses the key areas in which inorganic materials have been applied, considering: drug delivery; imaging; diagnostics and theranostics; hard matter restoration; and vaccines. Each chapter gives an overview of the major extant challenges in the research area, before presenting a systematic review of how inorganic materials have been applied to gain traction in the field. A clear focus is maintained on the fate of the applied materials in vivo, clinical considerations, and the path to translation from lab to clinic. With contributions from leading researchers, Biomedical Applications of Inorganic Materials will provide a comprehensive introduction for advanced undergraduates, postgraduates and researchers wishing to learn about the topic.

This book explores in depth a wide range of functional biomaterials-based systems for drug, gene delivery, and biomedical aspects. The chapters cover newer technologies such as polymeric micelle, pH-responsive biomaterials, stimuli-responsive hydrogels, silk fibroin, inorganic biomaterials, synthetic biomaterials, 3D printed biomaterials, metallic biomaterials, ceramic and hybrid biomaterials. It also describes the theranostic approaches for cancer therapy, the biomaterials-based nanofibers scaffolds in tissue engineering, as well as the strategies applications of metallic biomaterials for the medical and dental prosthetic field. This newer and updated approach will be attractive for biomedical engineering students working on materials science in the development of novel drug delivery strategies. The book will be an important reference for researchers and professionals working on biomaterial research in the pharmaceutical and medical fields.

Nanobiomaterials Science, Development and Evaluation examines the practical aspects of producing nanostructured biomaterials for a range of applications. With a strong focus on materials, such as metals, ceramics, polymers, and composites, the book also examines nanostructured coatings and toxicology aspects. Chapters in Part One look at materials classes and their synthesis with information on all major material groups. Part Two focuses on nanostructured coatings and practical aspects associated with the use of nanobiomaterials in vivo. This book brings together the work of international contributors who are actively engaged on the forefront of research in their respective disciplines, and is a valuable resource for materials scientists in academia, industry, and all those who wish to broaden their knowledge in the allied field. Focuses on the synthesis and evaluation techniques for a range of nanobiomaterials Examines nanostructured inorganic coatings for biomaterials Discusses issues related to the toxicology of nanobiomaterials Presents the practical aspects of nanobiomaterials
