Biomaterials are produced in situ and in vivo in the body using mainly hydration reactions, that is, reactions between phosphates, silicates or aluminates, and water. The nanostructural integration of these biomaterials in the body is controlled by six mechanisms. This book describes the new biomaterials based on nanostructural chemically bonded bioceramics and discusses their general and specific properties. It presents an overview of the nanostructural chemically bonded bioceramics, including their processing aspects, properties, integration with tissues, relation to other bioceramics and biomaterials, and nanostructural integration in different dental and orthopaedic applications.
