Experimental and Numerical Analysis of the Mobility of Immediately Loaded Dental Implants Using a Pig Model

The aim of this study was to model a system of implant and bone using the finite elements analysis (FEA). For this purpose immediately loaded dental implants were used. In an experimental analysis of preparations from pig jaws the force-displacement behaviour was measured using a self development set-up. With the aid of a micro computer tomograph (µCT) three dimensional surface models were reconstructed. These surface models were imported into the finite elements (FE) software package Marc/Mentat. Then the three dimensional surface models were transformed into FE-models, that mirror the geometry of implant and bone in detail. Comparison of the experimental achieved data and the numerical calculated data showed the magnitude of relative movements between implant and bone.
