Finite Element Modelling of Bioactive Contact in Bone-Implant Interface

The use of finite element analysis to model bone-implant contact with basal implants.

OBJECTIVE The purpose of this study was to develop a model that accurately represents the interface between bone and basal implants throughout the healing process. STUDY DESIGN The model was applied to the biological scenario of changing load distribution in a basal implant system over time. We did this through finite element analysis (FEA, or finite element method [FEM]), using multiple mode...

Finite Element Modelling of a Total Wrist Implant

The aim of the project was to create finite element model of a commercially available wrist implant to examine its behaviour under loading. The finite element model was validated by carrying out mechanical tests. Little is known about the mechanics of wrist implants under loading and how they interact with the surrounding bone. Surgical outcomes have been poor and further research is needed to ...

Finite Element Modeling of Tibia Bone and Implant

Finite Element Simulation of Contact Mechanics of Cancer Cells in Manipulation Based on Atomic Force Microscopy

The theory of contact mechanics deals with stresses and deformations which arise when the surfaces of two solid bodies are brought into contact. In elastic deformation contact occurs over a finite area. A regular method for determining the dimensions of this area is Hertz Contact Model. Appearance of atomic force microscope results in introduction of Contact ...

3D finite element non linear analysis on the stress state at bone-implant interface in dental osteointegrated implants.

PURPOSES The aim of the study was to assess by means a 3D finite element linear and non-linear analysis mechanical interaction between an implant-supported crown and surrounding tissues. MATERIALS AND METHODS A three-dimensional FEM model was developed. Four different material combinations for the abutment and the core were evaluated: Y-TZP - Y-TZP, Y-TZP - microhybrid composite, T - microhyb...
