Biomaterials, as noted earlier, are designed to have some desirable combination of properties, depending on the application. In the selection of a biomaterial for a specific application, it is worth recognizing at the outset that:

 The primary classes of synthetic materials, metals, ceramics and polymers, and natural materials have vastly different intrinsic (or inherent) properties;

 Within each class, the measured properties can cover a wide range.

A useful starting point is a qualitative understanding of the intrinsic properties of these different classes of materials. Then, we will present the intrinsic properties of these classes of synthetic materials and compare them with those of some natural materials. In Chapter 2, the basic principles for understanding the intrinsic properties of these classes of materials in terms of their atomic structure are presented.
