摘要
This chapter is an introduction to nanocomposite materials and its classifications with emphasis on orthopedic application. It covers different types of matrix n anocomposites in eluding ceramics, metal, polymer and natural-based nanocomposites with the main features and applications in the orthopedic. In addition, it presents structure, composition, and biomechanical features ofbone as a natural nanocomposite. Finally, it deliberately presents developing methods for nanocomposites bone grafting.
