Abstract
Aim And Objectives: The aim of the study is to evaluate the efciency of locking miniplates and conventional miniplates in the management of mandibular symphysis and para symphysis fractures. The objectives are to assess the Biteforce, Post-operative occlusion, Post operative complications, as Infection, mal union, non-union and Incidence of hard ware failure. Materials And Methods: This clinical study consisted of a sample size of 12 patients who reported to the department of OMFS, Government Dental College and Hospital, Kadapa, Andhra Pradesh with fracture of mandible in symphysis and Para-symphysis region. Patients were randomly divided into 2 equal groups of 6 patients each. Group A patients underwent open reduction and internal xation with locking miniplates and group B patients underwent ORIF with conventional miniplates. Results: In this study we found that the increase in bite force was more in group treated with locking miniplates compared to conventional miniplates, and it was statistically signicant. There was no statistical signicance regarding the parameters like post-operative occlusion, post-operative complications, infection malunion non-union and incidence of hard ware failure. The present study Conclusion: concluded that locking plate system is an extremely useful supplement to plate osteosynthesis as it increases the masticatory efciency. Clinically locking plates were found to be better than conventional miniplates in terms of functional improvement. As the present study was done with a limited sample of 12 patients, further clinical trials with larger sample size are suggested for more afrmative and conclusive results.
