Book Description
Ceramic materials that are specially developed for use as medical and dental implants are termed bioceramics. They include alumina and zirconia, bioactive glasses, glass-ceramics, coatings and composites, hydroxyapatite and resorbable calcium phosphates, and radiotherapy glasses. This is the first textbook in a field which is growing rapidly in clinical applications including orthopedics, otolaryngology, maxillo-facial and plastic surgery, oral surgery, periodontology, and tumor therapy. Fourteen chapters, written by world experts, describe the processing, compositions, properties, surface chemistry, tissue response, and clinical applications. There are also chapters on characterization and quality assurance testing, and the procedures that must be followed to satisfy regulatory requirements. A forecast of the future needs of the field and Appendices that summarize the relevant standards and test methods complete this unique book. The purpose of the book is to summarize and synthesize the very large and disparate body of literature in the field. Thus, it is easy to use as a textbook for an undergraduate or first year graduate course, or short industrial course, or as a reference source.

Handbook of Bioceramics and Biocomposites
Author: Iulian Vasile Antoniac
Publisher: Springer
ISBN: 9783319124599
Category : Technology & Engineering
Languages : en
Pages : 0
Book Description
This handbook describes several current trends in the development of bioceramics and biocomposites for clinical use in the repair, remodelling, and regeneration of bone tissue. Comprehensive coverage of these materials allows fundamental aspects of the science and engineering to be seen in close relation to the clinical performance of dental and orthopaedic implants. Bioceramics and biocomposites appear to be the most dynamic area of materials development for both tissue engineering and implantable medical devices. Almost all medical specialties will continue to benefit from these developments, but especially dentistry and orthopaedics. In this Handbook, leading researchers describe the use of bionanomaterials to create new functionalities when interfaced with biological molecules or structures. Also described are technologies for bioceramics and biocomposites processing in order to fabricate medical devices for clinical use. Another important section of the book is dedicated to tissue regeneration with development of new matrices. A targeted or personalized treatment device reduces drug consumption and treatment expenses, resulting in benefits to the patient and cost reductions for public health systems. This authoritative reference on the state-of-the-art in the development and use of bioceramics and biocomposites can also serve as the basis of instructional course lectures for audiences ranging from advanced undergraduate students to post-graduates in materials science and engineering and biomedical engineering.

Acetabular Revision Surgery in Major Bone Defects
Author: Eduardo GarcĂa-Rey
Publisher: Springer
ISBN: 3319985965
Category : Medical
Languages : en
Pages : 223
Book Description
This book reviews the most important issues related to acetabular revision hip surgery and assesses the different management procedures that are currently used in light of the challenging major defects. Since the 1970s there has been a continual rise in the annual number of total hip arthroplasty (THA) procedures which has increased the demand for revision surgeries. Most revisions operations of the hip are the result of acetabular problems and early failures are usually related to acetabular bone defects in complex primary THAs. Long-term failures are mostly due to wear debris and osteolysis-related problems and both types of complications are presented throughout the book. Surgeons with a special interest in hip reconstruction surgery will find this book to be an essential resource for successfully dealing with highly complex revision procedures.

Smart Ceramics
Author: Ajay Kumar Mishra
Publisher: CRC Press
ISBN: 1351671634
Category : Science
Languages : en
Pages : 284
Book Description
Recent advances in nanotechnology have paved the way for the development of new smart materials. The term "smart ceramics" refers to ceramic materials fabricated from ultrafine particles. They have attracted the attention of researchers and scientists thanks to their potential to manipulate the length scale in the nanorange, leading to better and some unusual material properties. Smart ceramics ensure control of particle size, surface contamination, and degree of agglomeration. They play a crucial role in challenging applications such as bone surgery (e.g., the development of substitutes for load-bearing bone parts) and in biomedical science, especially in tissue engineering, dental applications, and drug and antigen delivery using modified ceramics. Porous nanostructured ceramics have potential use in both simple and complex applications, such as bioimaging, sensors, paints and pigments, optics, and electronics, because of their surface- and size-dependent properties. For the synthesis of smart ceramics, the sol-gel route has been mainly utilized because of its ability to produce a large variety of compositions and to ensure homogeneous mixing of the constituent particles at low temperature. This book describes the innovations in technologies through the development of functionalized ceramic materials for various applications. It also describes recent and expected challenges, along with their potential solutions, in advanced techniques for the synthesis and characterization of nanostructured ceramics and their composites: bioceramics, bioactive ceramics, multifunctional nanoceramics, transparent ceramics, nanocore shells, nanowires, thin films, nanotubes, and nanorods. The applications include the environment, health care, electrochemical sensors, high-temperature superconductors, nuclear reactor fuels, electrical insulators, refractory materials, electrical transformers, and magnetic core memory. The book will benefit researchers, scientists, engineers, and technologists working in the industry and in national and international research laboratories; academics who are interested in traditional and advanced smart ceramic composites; and students pursuing their postgraduate, graduate, and undergraduate degrees in smart ceramics, nanomaterials, nanoscience, and engineering.
