Abstract
Polymer/Ceramic composites are now being considered as third-generation orthopedic biomaterials due to their ability to closely match properties of natural bone when compared with first generation and second generation bone substitute materials. The combination of polymers and ceramic phases leads to composite materials with improved mechanical properties due to the inherent higher stiffness and strength of the inorganic material. Among all existing biomaterials calcium phosphate ceramics have been extensively used for bone replacement and augmentation due to their similarity to the mineral component of bone. They also have the additional benefits of biocompatibility, bioactivity and nontoxicity. This review focuses on selected polymer ceramic composites, their physical and biological properties. It also includes their current biomedical applications like bone fillers, coatings, cements, scaffolds and drug carriers. These composites are promising as bone substitute materials. They have great potential starting from bone augmentation, to controlled delivery devices to revolutionize the field of hard tissue engineering.
