Evaluation of Dentinal Viscoelastic Properties Based on its Microstructural Characters

Article Preview

On the basis of the characters of dentinal microstructures, a new Three-Parameter-Solid viscoelastic mechanics model which can predict strain creep, stress relaxation and instant elasticity with anisotropic constitutive relation for the human dentin is developed in this paper. The porous protein-mineral model is adopted to obtain the independent dentinal viscoelastic moduli based on its microstructural characters. The influencing mechanisms and the viscoelastic properties of the microstructural dentin are also evaluated by the Three-Parameter-Solid viscoelastic model. The viscoelastic predictive results obtained from the Three-Parameter-Solid viscoelastic model agree well with those from the experimental investigation in both wet and dry situations.
