Aplication of Atomic Force Microscope for Mechanical and Tribological Characterization of Teeth and Biomaterials
Journal Title: Tribology in Industry - Year 2009, Vol 31, Issue 1
Abstract
This paper describes analysis of mechanical and tribological properties of human teeth and of their restorative materials by use of the atomic force microscope (AFM) and its combination with nanoidentation. By use of the AFM bending mode, stiffness, compliance, hardness and modulus of elasticity of dental enamel and of restorative materials are measurement. By use of the AFM lateral force the coefficients of friction of teeth and of their restorative materials are estimated, respectively. Tribological characterization of human teeth and of their restorative materials, under lubricated condition, was performing in artificial saliva which reduces the friction. Direct measurement of tribo-mechanical behavior of human teeth and of their restorative materials is of importance to clinical tooth preparation and to the development of the new artificial dental materials with a long lifetime.
