ABSTRACT
Eggshell is an inexpensive and abundant biomaterial with interesting properties, which can be tailored to numerous potential applications. This chapter foregrounds the promising area of research in the application of eggshell waste for medical and dental benefits. Hydroxyapatite polymer composite has been used as a biocomposite and osteo-conductive substitute for bone repair and implantation. The chapter highlights the use of eggshell-derived hydroxyapatite as an adaptive innovative bone graft substitute that has shown favourable results in the treatment of bone and dental defects. It also discusses the medical application of collagen extracted from eggshell membrane. The chapter provides an overview of literature related to eggshells. The focus is on the extraction of the starting material from eggshell powder for the synthesis of hydroxyapatite. A. E. Broadus revealed that calcium is an essential requirement to the human body for a range of physiological functions and for the maintenance of bone tissues throughout life.
