Finite Element Analysis of Stress and Strain Distribution in the Bone around the Implants used for Orthodontic Anchorage

Abstract

Biomechanical influences on bone structure play an important role in the longevity of bone around an implant. The quantity and direction of applied force influence the implant and cause deformation of the bone. FEA was used to analyze the changes in the bone on loading the implant with orthodontic force in oblique and vertical directions and orthopedic force. The Mini-implants used in the present study efficiently resisted the oblique loading. But their use, for the purpose of orthopedic loading is questionable. FE models showed the area with the highest stress and strain to be around the neck of the implant and the surrounding bone at the cervical margin.
