Throughout history, people use different types of biomaterials to repair or replace damaged human tissues. Ancient Egyptians used golden wires to replace the missing teeth; Ancient Mayans used nacre or mother of pearl to achieve the same goal 1, 2. Fast forward to the 20th century; Sir Ridley used Perspex as the material for intraocular lenses 1. Many surgeons pioneered using synthetic polymeric membranes as the material for kidney dialyzers 1. The modern time of biomaterials has come. Science, instead of try-and-error, has been developed to study biomaterials systematically. Professor Larry Hench, who is the inventor of Bioglass©, came up a classification of three generations of biomaterials, starting from bioinert materials to bioactive materials, to the combining of bioactive materials and resorbable materials 3.
