Comparison of Three Internal Fixation Techniques in Mandibular Sagittal Split Osteotomy, A Finite Element Analysis

The aim of this study was to analyse and compare the biomechanical properties of 3 internal fixation techniques (2.0mm bi-cortical screws, 2.0mm miniplate and 1.7mm miniplate) in mandibular sagittal split osteotomy (SSO). A 3-D hemi-mandible model was developed from a patient's skull CT. It underwent sagittal split osteotomy (SSO) virtually and was reproduced 9 models consisting of the 3 fixation techniques with mandibular movements of 3mm setback, 3mm advancement, and 7mm advancement. Bite forces applied were 50, 75, and 100N for the incisors, and 100, 200 and 300N for the molars. (Source: The British Journal of Oral and Maxillofacial Surgery)
