Abstract
The aim of the current study is to examine numerically the stress intensity along bone-implant interface for selected implant systems under occlusal load using finite element analysis (FEA) and confirming the result experimentally by optical technique. To see the biomechanical performance at bone-implant interface the five types of implant systems are chosen for the current study. A three-dimensional (3D) computer aided design (CAD) is prepared using CreO Parametric modeling software. A non-linear contact between implant and surrounding bone is defined to analyze the stress intensity in the cancellous bone under the applied load of 100 N axial directions, 40 N laterals (Bucco-lingual) direction and 100 N oblique at 45 degree to the longitudinal axis of implant. An experimental photoelastic technique (Optical technique) is used to predict the stress intensity in a cancellous bone near the bone-implant interface using Tardy's method of compensation. A homogeneous blend of Araldite and hardener material is used to prepare a photoelastic block model. The maximum value of stress intensity is noted in Type-I implant system at apical part of implant whereas minimum value was noted in Type-III implant system under lateral and oblique loads. Stress intensity in cancellous bone at the bone interface is found to be more significant to the applied oblique load. © 2020 The Authors. Published by Elsevier Ltd.
