Abstract

Mechanical properties is critical for developing dental materials and designing dental prosthesis. The aim of this study is to investigate the mechanical properties of human enamel material based on resonant ultrasound spectroscopy method (RUS). First, some pure enamel specimens were prepared carefully from five fresh human teeth. Under the assumption of transverse isotropic biomaterial, for all enamel specimens, the theoretical resonant frequencies were calculated using Rayleigh-Ritz method, the experimental resonant frequencies were extracted from resonant ultrasound spectroscopy, and then the optimal elastic constants was estimated based on based on the experimental and theoretical resonant frequencies using Levenberg-Marquardt method. In addition, the mechanical parameters, including Young’s moduli, Shear moduli, and Poisson’s ratios, were also calculated based on the optimal elastic constants. The result showed that RUS method exhibited more consistency of mechanical parameters than previous studies. This method may provide more precise measurement of mechanical properties of Enamel materials.
