Abstract
AIM OF THE STUDY: The present study compares lingual stability of monocortical miniplate fixation with that of bicortical miniplate fixation in parasymphysis fracture using FEM analysis. MATERIALS AND METHODS: Using multislice CT scanner, 3D FEM of patient's mandible was created. Fracture was simulated at parasymphysis region and fixed with 2-mm titanium miniplates and screws of length 8, 10, 12 mm, respectively. Loading force of 120 N applied at molar region and 62.8 N at incisor region. These three models were imported into ANSYS Workbench FEM software. RESULT: There is no significant difference in results between bicortical fixation and monocortical fixation. CONCLUSION: It was concluded that use of monocortical fixation provides sufficient lingual stability. This suggests monocortical fixation system is as reliable as bicortical fixation.
