INTRODUCTION
In surgery, a biocompatible material (sometimes shortened to biomaterial) is a synthetic material used to replace part of a living system or to function in intimate contact with living tissue. The CLEMSON UNIVERSITY ADVISORY BOARD for BIOMATERIALS has formally defined a biomaterial to be "a systematically and pharmacologically inert substance designed for implantation within or incorporation with living systems." By contrast a biological material is a material such as bone matrix or tooth enamel, produced by a biological system.
The use of biomaterials, as indicated in Table 1, include replacement of a body part that has lost function due to disease or trauma, to assist in healing, to improve function, and to correct abnormalities.
Table 1 Uses of Biomaterials
