Table 1.1 Typical mechanical properties of dental biomaterials


Dental biomaterials are used in laboratory procedures and for the restoration and replacement of teeth and bone. Material selection must consider function, properties, and associated risks, and all dental biomaterials must satisfy certain criteria (Box 1.1).

Mechanical properties are important since teeth and r/>
