Voxel-based micro-finite element analysis of dental implants in a human cadaveric mandible: Tissue modulus assignment and sensitivity analyses.

ABSTRACT: The success of dental implant treatment is related to the complex 3-dimensional (3D) biomechanics of the implant-bone interaction. In this work, 3D numerical models are built based on micro X-ray computed tomography (micro-CT) images of a cadaveric mandible specimen with implants placed in it. The simulation results show that the computed strain values in bone are sensitive to the uncertainties in trabecular tissue modulus and fairly insensitive to the modulus of implants and teeth and the detailed geometry of the fixed boundary condition. A bone-volume-fraction (BV/TV) based method is proposed to assign the tissue moduli of bone elements based on their BV/TV to increase the connectivity of the mesh and to improve the accuracy of the models. These models are potentially powerful for calcul
