Abstract

Abstract: Since the natural ligament responsible for the fixation of teeth in jawbone is destroyed when artificial replacements are implanted, the mechanical stimulation of the bone is reversed. Idea of this research project is the development of active implants which provide additional electrical stimulation for bone adaption. A new electromechanically driven bone remodeling theory will be developed and the osseointegration of bone implants has been simulated by means of bio‐active interface theory. The thin bone‐implant interface is described by the Drucker‐Prager plasticity model. Besides the consistent combination of electromechanical bone remodeling simulation, 3D‐finite element model of lower mandible has been reconstructed. As the micromotions at the implant‐abutment level are reported to be a major determinant of longterm implant success, the osseointegration process is limited by micromotion threshold. The applicability is indicated on a dental implant in order to optimize new developed techniques for activating implants with piezo‐electric coatings. (© 2015 Wiley‐VCH Verlag GmbH & Co.
