Finite Element Prediction of Cortical and Trabecular Bone Remodelling in an in Vivo Model of Bone Adaptation
INTRODUCTION Bone remodelling is known to be a function of its mechanical environment. However the precise nature of the mechanical signal governing bone formation is poorly understood. As well as improving our understanding of bone formation and bone quality maintenance, a quantitative understanding may ultimately reveal novel approaches for the treatment or prevention of age related fractures...
متن کاملTrabecular surface remodeling simulation for cancellous bone using microstructural voxel finite element models.
A computational simulation method for three-dimensional trabecular surface remodeling was proposed, using voxel finite element models of cancellous bone, and was applied to the experimental data. In the simulation, the trabecular microstructure was modeled based on digital images, and its morphological changes due to surface movement at the trabecular level were directly expressed by removing/a...
متن کاملEfficient Harmonic Simulation of a Trabecular Bone Finite Element Model by means of Model Reduction
Three-dimensional serial reconstruction techniques allow us to develop very detailed microfinite element (micro-FE) model of bones that can very accurately represent the porous bone micro-architecture. However, such models are of very high dimension and, at present, simulation is limited to a linear elastic analysis only. In the present paper, we suggest to use model reduction in order to enabl...
متن کاملFinite element simulation of bone remodelling in human mandible around osseointegrated dental implant
Modern dental implant is a biocompatible titanium device surgically placed into a jawbone to support a prosthetic tooth crown in order to replace missing teeth. Implants are superior to conventional prostheses, in both function and long-term predictability. However, placement of an implant changes the normal mechanical environment of jawbone, which causes the bone density to redistribute and ad...
متن کاملFinite Element Simulation of Bone Microstructures
The geometric construction of finite element spaces suitable for complicated shapes or microstructured materials is discussed. As an application, the efficient computation of linearized elasticity is considered on them. Geometries are supposed to be implicitly described via 3D voxel data (e. g. μCT scans) associated with a cubic grid. We place degrees of freedom only at the grid nodes and incor...
