Overview of Biomaterials
Human life is invaluable; however, quality and survival of life is greatly affected by numerous factors, including medical complications caused by diseased, damaged, or aged tissues or organs. These circumstances often call for surgical treatments to repair, replace, maintain, or augment the functions of affected tissues or organs using some additional functional components. Traditionally, they have been treated with the help of tissues or organs procured from patients or donors. Depending on the location of reimplantation of the procured tissue (also known as graft), they are termed autograft, allograft, or xenograft (see Figure 1.1).
