Application of Biomaterials in Dentistry

A biomaterial is any substance to fix the defects, repair or replacement of defective organ in the body. Over the past thirty years, a new field of materials science has emerged as biomaterial. It is a result of development and the integration of various branches of materials (metals, composites, ceramics and polymers).These materials are synthetic (synthetic mineral or organic) or natural which have been designed and made to work and fix defects in the organism (mostly men). One of the familiar and experienced biomaterials is dental materials (mercury compounds) for dental fillings. In this way, industries related to biomaterials, gradually emerged over the last thirty years, especially in United States of America, and now has allocated a huge number of world trade (about 70 billion dollars a year), which more than 700 companies are involved in it. A very important point is that, these materials are sold very low in volume but at high price, and are considered as strategic products. In this paper, we try to investigate application of these biomaterials in dentistry [1-3].
