Book Description
Coatings based on hydroxyapatite and calcium phosphates have a significant relevance in several research fields, such as biomaterials, cultural heritage, and water treatment, due to their characteristic properties. Hydroxyapatite can easily accommodate foreign ions, which can either be incorporated into the lattice, thanks to its specific lattice characteristics, or be adsorbed onto its surface. All these substitutions significantly alter the morphology, lattice parameters, and crystallinity of hydroxyapatite so they influence its main properties. These ion substitutions can be sought or can derive from substrate contaminations, which is an important aspect to be evaluated. Finally, this capability can be used to obtain hydroxyapatites with specific properties, such as antibacterial characteristics, among others. For these reasons, the aim of this Special Issue is to document current advances in the field of ion-substituted hydroxyapatites and highlight possible future perspectives regarding their use. Contributions in the form of original articles and review articles are presented, covering different areas of application.

Book Description
Due to a great chemical similarity with the biological calcified tissues, many calcium orthophosphates possess remarkable biocompatibility and bioactivity. Materials scientists use this property extensively to construct artificial bone grafts that are either entirely made of or only surface-coated with the biologically relevant calcium orthophospha

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.

Book Description
Handbook of Ionic Substituted Hydroxyapatites provides scientists and researchers with comprehensive information on the synthesis processes of hydroxyapatite, also explaining the application of substituted hydroxyapatite. The book's content is very structured and explanatory, starting with a detailed overview of biological apatite in bones and teeth, as well as a presentation of the analytical tools for hydroxyapatite. Bioceramics and the relative modern and emerging processing techniques are covered, as is 3-D printing, which has gained increasing importance within biomedical materials and in the use of hydroxyapatite in tissue engineering. Finally, the advantages and disadvantages of using ionic substitutions in clinical application are presented. Students and researchers in disciplines, such as Material Science, Ceramics, and Bioengineering will find this book to be very helpful in their work. It will also be a valuable resource for practitioners and surgeons in orthopedics, perio/implantology and maxillo-facial disciplines, and professionals working in R&D in ceramics and pharmaceuticals. - Provides responses to the lack of scientific information about hydroxyapatites for biomedical applications - Solves researchers' issues regarding phase changes with respect to substituted ions and how these substitutions can alter/improve the properties of stoichiometric hydroxyapatite - Explains modern clinical applications and the effects of apatites within biomedical applications - Includes both the advantages and disadvantages of using ionic substitutions in clinical application

Book Description
Hydroxyapatite in the form of hydroxycarbonate apatite is the principal mineral component of bone tissue in mammals. In Bioceramics, it is classed as a bioactive material, which means bone tissue grows directly on it when placed in apposition without intervening fibrous tissue. Hydroxyapatite is hence commonly used as bone grafts, fillers and as coatings for metal implants. This important book provides an overview of the most recent research and developments involving hydroxyapatite as a key material in medicine and its application. - Reviews the important properties of hydroxyapatite as a biomaterial - Considers a range of specific forms of the material and their advantages - Reviews a range of specific medical applications for this important material

Reflecting the progress in recent years, this book provides in-depth information on the preparation, chemistry, and engineering of bioceramic coatings for medical implants. It is authored by two renowned experts with over 30 years of experience in industry and academia, who know the potentials and pitfalls of the techniques concerned. Following an introduction to the principles of biocompatibility, they present the structures and properties of various bioceramics from alumina to zirconia. The main part of the work focuses on coating technologies, such as chemical vapor deposition, sol-gel deposition and thermal spraying. There then follows a discussion of the major interactions of bioceramics with bone or tissue cells, complemented by an overview of the in-vitro testing methods of the biomineralization properties of bioceramics. The text is rounded off by chapters on the functionalization of bioceramic coatings and a look at future trends.

Book Description
The chemistry, structure and biological importance of octacalcium phosphate (OCP) are thoroughly discussed in this volume, which covers a wide scope of topics relevant to the field of calcium phosphates in general. The first chapter reviews the structures of OCP and other important calcium phosphates. It is followed by a description of the mimicry of OCP growth in vivo using in vitro model systems and an extensive review of OCP in biological systems. The remarkable ability of OCP to incorporate biologically relevant organic carboxylates into its structure is also discussed, along with the solubility and surface properties of calcium phosphate salts, and amorphous calcium phosphate and its relationship to OCP. The last chapter centers on the emerging technology of calcium phosphate cements as bone defect repair materials. The book provides in-depth, up-to-date information to all scientists studying calcium phosphate chemistry, biomineralization, pathological calcification, dental caries, biomaterials, and recovery of environmental phosphorus.
