The biomechanical analysis of multi-implant prostethic systems necessarly requires the use of three dimensional finite element models. The present case refers to the response of the bone-prosthesis compound in case of detachment of the first implant from bone (reference to notation of Fig. 2).
Different elastic properties are assumed for the cortical and trabecular region of bone. An intrusive force of 200 N and a trasnversal force of 20 N in lingual-buccal direction is applied at the tip of the cantilever.
The magnitude displacement field for mandible and prosthetic systemis is depicted in Fig.1. A detail of the magnitude displacement field for bar and implants is shown in Fig. 2 from lingual to buccal side. In Fig. 3 the magnitude displacement are shown for a section at the level of detached implant.
