3-D Finite Element Method Analysis Of Low Elastic Modulus β Ti Alloy Implant-bone Interface Stress Distribution

Implant is one of the popular clinical methods to fix the dentition defect. With the development of the materials and technology of the implants, implants can be applied to all common dentition defects in clinical work. Due to the implant is in the alveolar bone, the reparation effect is closely related to the biomechanical compatibility of the implant. The elastic modulus of newly developed β-Ti alloy is more like that of human bone, and the research on its biomechanical compatibility can supply more choice of the implant material.Finite Element analysis is a stress analysis method that uses the computer to solute the mechanics problem of continuous medium. This method has been widely used in every field of stomatology and demonstrated great superiority. So it is believed that Finite Element analysis is most advanced and effective method in biomechanics research. In this article, we used Slim CT, DICOM, Mimics and several reverse engineering software together to help building 3D finite element model of the mandible, and approached the effect on stress of implant-bone interface with different materials that have their own elastic modulus. After that, we draw these conclusions:...
