Materials science and modern Medicine

Introduction

Modern medicine would be revolutionized , considering the immense number of benefits provided by advanced and complex biomaterials . These materials are being made in such a way that they are similar in composition and structure to the natural structures and tissues of the body . Hence , they can more closely restore or replace the functions of the missing or diseased body part . Several medical procedures such as require materials including

implants , heart valves , ophthalmic devices dental materials , cancer treatments , etc . Today biomaterials are serving to deliver drugs and radiotherapy precisely to certain parts of the body and in this way improve the efficiency , safety and outcome of treatment . Implantable ceramics , which have been developed since twenty years , seem to be more and more natural and have immense dental and medical applications . Previously plastics and metals were utilized which had a huge number of limitations . These materials were neither safe nor effective . One such example has been the use of polyethylene which has been used as an implant material . Studies have shown that the material slowly gets absorbed by the tissues present around it requiring replacements . Newer materials tend to last longer , function better , are definitely safer and more effective (Missouri S T , 2003 .Ceramics and Glass materials

Use of ceramics and glass material are a major advantage on medicine compared to the materials it replaced . They are being utilized in a wide range of clinical...
