Aim And Objective:
The present study compared the stability of fracture fragments in the management of bilateral parasymphysis mandible fracture with Miniplate fixation and Reconstruction plate fixation using finite element analysis.
Material And Method:
3D FE Mandible model was created using CT scanner. Two bilateral parasymphysis mandible fracture models were created. Model 1 was fixed with Miniplates, and Model 2 was fixed with Reconstruction plate. Loading forces of 120 N at molar region and 62.5 N at incisor region were applied. These two models were imported to ANSY'S Workbench Software.
Result:
Miniplate fixation model showed comparatively reduced gap between fragments than Reconstruction plate. But the gap values of both the models were within the physiologic limit of healing under this specific loading. Analytically Miniplates were superior to Reconstruction plate in the management of bilateral parasymphysis fracture.
Conclusion:
Analytically Miniplates are superior to Reconstruction plate in the management of bilateral parasymphysis fracture. As the masticatory forces were reduced during fracture healing period, both fixations provide satisfactory healing. So both Miniplate and Reconstruction plate can be considered as fixation method for bilateral parasymphysis mandible fracture.
