AIMS AND OBJECTIVES: To perform comparative finite element analysis (FEA)for 2.0 mm standard miniplate and 1.5 mm microplate in isolated symphyseal mandibular fractures.
MATERIAL AND METHOD: Two FE models of mandible were developed and symphyseal fracture was created in both of them. Each fractured model was reduced and fixed using two mini plates and two microplates, respectively according Champ's principle. Stresses thus developed in the plates after application of masticatory load were observed in the models.
RESULTS: Results of the study indicated there was no significant difference in the stresses developed in either of the bone plating system.
CONCLUSION: 1.5 mm Microplates can be used in place of 2.0 mm miniplates in isolated symphyseal fractures of the mandible.
