4. THREE DIMENSIONAL MODELS OF AN IMPLANT SYSTEM

The biomechanical analysis of multi-implant prostethic systems necessarly requires the use of three dimensional models. The present analysis shows the functional response of the bone-prosthesis compound in case of osseointegrated implants conditions .
Different elastic properties are assumed for the cortical and trabecular regions of bone. With reference to notation of Fig. 2 the loading condition is defined as follows: an intrusive force of 50 N and a transversal force of 5 N are applied on first and third implant; an intrusive load of 200 N and a transversal force of 20 N are applied on second implant.
Fig. 1 shows the magnitude displacement field for mandible and prosthesis. Fig. 2 shows the magnitude displacement field for the mandible only, while Fig. 3 shows a detail of the section at the level of the first implant.
