'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.

人牙力学性能研究综述.

“青铜牙”在一定程度上反映了天然牙的力学性能。它们的机械性能类似于坚韧的金属，这些性能的梯度是由外向内的。这些属性赋予人类牙齿有效的咀嚼能力。了解人类牙齿和牙科材料的各种力学性能是开发修复材料的基础。本研究综述了牙釉质和牙本质的弹性、动态力学性能（粘弹性）和断裂力学性能，以更深入地了解人类牙齿的力学性能。
