Design and Analysis of a New Dental Implant using Finite Element Method

An overall treatment with dental implant consist of several essential parts, including a superstructure containing fixture (part of the implant embedding in the bone), abutment (a machined tapered prepared superstructure attached to the fixture), a retainer (which hold the aesthetic portion of the restoration) and the crown (aesthetic part of the restoration). In this common kind of restoration, crown is cemented to metal framework. However, in this research a novel method of design of dental implant is presented which includes only two components: Integrated implant, and Crown. The new design is based on an integrated implant which enables dentist to fit the crown by a snap-fit ringinstantly. In order to carry out stress analysis, the finite element method (FEM) is applied on implant and bones to verify different loading conditions. The results of FEM analysis indicate thatthe proposed design undergoes different loading conditions successfully.
