Finite Element Analysis (FEA) of Perpendicular Plating Versus Conventional Plating in Mandibular Symphysis Fracture.

ABSTRACT

AIM AND OBJECTIVE: To perform the comparative finite element analysis of conventional and perpendicular plating in mandibular symphyseal fracture. MATERIAL AND METHOD: Two FE model of mandible were developed and symphyseal fracture was created in both of them. Each fractured model was fixed by conventional method 2.0 mm system and perpendicular method 2.00 mm system. Stresses which developed in plates and mandible after application of load were observed in the model. RESULTS: Results of the study indicated that perpendicular method was more resistant to displacing forces and rest of the parameters was within the permitted limits. CONCLUSION: Perpendicular method was reasonably effective as conventional method of fixation for mandibular symphyseal fracture.
