This book provides an overview of the composition of polymeric and ceramic bone cements. It also discusses complex, biomimetic structures based on biomaterials, such as cells and bioactive molecules, which more closely resemble natural bone The first chapter describes the main concepts of the cementation process and the parameters affecting it, while the second chapter focuses on the composition and structure of candidate biomaterials. Lastly, the third and fourth chapters present recent research aimed at improving the ability of naked biomaterials to enhance bone healing by adding cells and bioactive agents.

This book reviews drug delivery systems as mechanisms to introduce therapeutic agents into the body to help or improve tissue function, and examines different drug delivery systems applied in various organs. To date, polymeric systems, ceramic particles or composites have been used in different applications such as injectable, coatings of implants, scaffolds, or implantable devices. Such systems should be able to retain the therapeutic agent and release it in uniform amounts at a specific time.
