Stress distribution of the variable dynamic loading in the dental implant: A three-dimensional finite element analysis

Stable osseointegration between implant threads and the surrounding marginal bone, provides the mechanical base of an implant for daily chewing activity. The contact area of implantbone interfaces and the concentrated stresses, on the marginal bones are principal concerns of implant designers. In this work, we numerically analyze by the finite element method the distribution of the equivalent stress and their level in the bone, the most fragile element of the dental prosthesis. Each set of the model contained a crown, framework, abutment, implant and bone, subjected to variable dynamic loading according to time. © 2017 Trans Tech Publications, Switzerland.
