An Introduction and History of the Bioactive Glasses

When the hierarchy turns towards higher level, the molecular events become more complex and convoluted. The human embryo development is quite complex as it originates from a 32-celled stage and metamorphoses by a series of metabolic and physical processes. The process of fetus formation is full of breathtaking complexity as it involves the development of lungs, heart, gut, nerves, limbs, bones, blood vessels, cartilages, circulatory system, nervous system and excretory system. The constant wear and tear of muscles, joints and other vital body tissues takes place during the lifetime of human body. Due to the advancement of medical science, artificial limbs and transplantation have helped the human body to resume the day-to-day chores, but the biomaterials have revolutionized the world due to their capability to repair the damaged tissues by self-healing mechanism. These days, the bioactive materials have become an imperative and indispensable tool for the medical science due to their numerous advantages. Hence, the current focus is given on the history, categories and requirements of the biomaterials especially bioactive glasses (please consult the Editor’s note in order to clarify the usage of the terms bioglass, bioactive glass and biocompatible glasses).
