New rigid internal fixation layout for sagittal split osteotomy: finite element analysis comparison against other two estabilished methods

Background: Numerous rigid internal fixation (RIF) techniques in orthognathic surgery for bilateral split osteotomy (BSSO) have been reported in the literature, but there is no consensus about the best choice. Finit element analysis (FEA) improved the evaluation of these osteosyntheses methods in terms of many aspects of mechanical behavior.
