A Study on the Design of Support of Osseointegrated Implant for the Two Dimensional Finite Element Analysis

ーComparison with the Absolute Values of Displacement Measured from Brånemark Implant Applied to Mandible of Dogー

Abstract

Recently, Finite Element Analysis (FEA) has been often used to study the deformation of osseointegrated implant because its displacement increases in proportion to load increase. In this study, the reliability and problems of FEA were investigated by comparing the measured values in dogs and the analyzed values of FEA. It was revealed that analyzed values were reliable when fixture was supported only by compact bone around the upper region of the fixture. However, it seemed problematic to analyze when the fixture was supported only by compact bone beside the fixture. Therefore, it was very important to choose suitable initial conditions especially when the fixture was supported in an unusual compact bone state.
