In order to study comparatively the behaviour of the bone-implant interface at mechanical stresses depending on the length of the implant turns, we chose a complex case, a total bimaxillary edentate. 7 implants were virtually inserted into the maxilla (2 pterigoid implants in the lateral regions and 3 implants in the frontal region), and 4 implants were inserted into the mandible (two in the premolar regions and two corresponding to the canines). The FEA analyzes were performed separately for the maxilla and for the mandible, applying a force of 200N on each type of implant. The critical areas, in which the extreme values of the strains develop, are located into the bone on the neck-implant level, and its apex level, regardless of the type of implant and regardless of the maxillary or mandibular area where the implants were virtually inserted. Implants with small turns induce lower stresses and deformations, compared to implants with large turns.
