Ceramic-polymer nanocomposites for bone-tissue regeneration... 

This chapter reviews biomedical grade ceramic-polymer nanocomposites, focussing on their impact and recent trends in the field of bone grafting and bone-tissue regeneration. 

Biomaterials must be properly selected because their physical, mechanical and biological properties will determine, to a great extent, the properties of the tissue-engineering scaffold. In Section 15.4, the main characteristics of monolithic biomaterials, precisely ceramics and polymers, are depicted, whereas in Section 15.5 the potential of ceramic-polymer nanocomposites in bone-tissue regeneration is illustrated. 

Nanomaterials are often reported to possess snperior properties over their microscale connterpart. Moreover, natnral bone is a typical example of a nanocomposite material (see Section 15.2). Therefore, the design of a bone graft in the form of nanocomposite is perceived beneficial over monolithic and microcomposite materials. The main advantages presented by ceramic-polymer nanocomposites for regenerative medicine, as compared to conventional ones, are listed below ... 

Ceramic-polymer nanocomposites are generally processed through three different methods (1) conventional mixing (2) self-assembly approach and (3) tissue-engineering approach.
