Calcium Phosphate Bone Cements

Biomaterials utilized in biomedical applications are of various characteristics and cements are unique in their in situ , biomimetic formation ability. They present the most topographically complex surfaces that usually elicit a favorable cellular response for tis- sue regeneration. In addition their composition may provide an effective chemical gradi ent around the resorbing implant to induce desired cellular activity that leads to rapid wound healing and regeneration. These are the main reasons for many cement systems to function well in the body, especially as hard tissue replacements. The properties and the setting mechanisms of the clinically most relevant cement system, calcium phosphate cements have been elucidated in this chapter.
