‘Bronze teeth’reflect the mechanical properties of natural teeth to a certain extent.Their mechanical properties resemble those of a tough metal,and the gradient of these properties lies in the direction from outside to inside.These attributes confer human teeth with effective mastication ability.Understanding the various mechanical properties of human teeth and dental materials is the basis for the development of restorative materials.In this study,the elastic properties,dynamic mechanical properties(visco-elasticity)and fracture mechanical properties of enamel and dentin were reviewed to provide a more thorough understanding of the mechanical properties of human teeth.

‘Bronze teeth＇ reflect the mechanical properties of natural teeth to a certain extent. Their mechanical properties resemble those of a tough metal, and the gradient of these properties lies in the direction from outside to inside. These attributes confer human teeth with effective mastication ability. Understanding the various mechanical properties of human teeth and dental materials is the basis for the development of restorative materials. In this study, the elastic properties, dynamic mechanical properties （visco-elasticity） and fracture mechanical properties of enamel and dentin were reviewed to provide a more thorough understanding of the mechanical properties of human teeth.
