Abstract
Introduction: The aim of this study was to employ the finite element method (FEM) to compare the stability of 2.0 mm titanium screws in a triangular configuration with that of a 2.0 mm titanium miniplate as osteosynthesis material following bilateral sagittal split osteotomy. Material: A model of the mandible was produced, consisting of 19854 elements and 4285 nodes. The mechanical parameters of the materials investigated were taken from the literature and notified by the manufacturer. Results: On condition that the materials were subjected only to their respective ultimate tensile stress, it was possible to neutralise a masticatory force of 1246 N (Newtons) with the miniplate and of 1675 N with the bicortical triangular screw configuration. The strain limit was determined by the peri-implant bone and not the osteosynthesis material. Conclusion: The finite element method (FEM) appears to be suitable for simulating complex mechanical stresses in the maxillofacial area, as also confirmed by the agreement between our data and those in the literature, and with clinical experience. It should enable considerable savings to be made in terms of time, material and animal experiments in the future development of osteosynthesis materials and techniques.
