Abstract
In the present world, where there is increased obesity and poor physical activity, the occurrence of bone disorders has also been increased steeply. Therefore, a significant progress has been made in organ transplantation, surgical reconstruction, and the use of artificial prostheses to treat the loss or failure of an organ or bone tissue in the recent years. Bone contains considerable amounts of minerals and proteins. The major component of bone is hydroxyapatite [Ca(10)(PO(4))(6)(OH)(2)] (60-65%) and is one of the most stable forms of calcium phosphate and it occurs along with other materials including collagen, chondroitin sulfate, keratin sulfate, and lipids. To remedy bone defects, new natural and synthetic materials are needed, which will have very similar properties as that of natural bone. Bone tissue engineering is a relatively new and emerging field, which paves the way for bone repair or regeneration. Polymers can serve as a matrix to support cell growth by having various properties such as biocompatibility, biodegradability, porosity, charge, mechanical strength, and hydrophobicity. Considerable attention has been given to chitin and chitosan composite materials and their applications in the field of bone tissue engineering in the recent years, which are natural biopolymers. This chapter reviews the various composites of chitin and chitosan, which are proved to be potential materials for bone tissue regeneration.
