Mandibular Symphysis Fractures; Comparison of Conventional Mini Plates Versus 3D Mini Plates in the Fixation of Isolated Mandibular Symphysis Fractures in Abbasi Shaheed Hospital Karachi - a Clinical Study.
Professional Med J Jan ;25(6):815-22.

Introduction: Mandible is one of the most commonly fractured bones in maxillofacial trauma. Mandibular symphysis is a common site of mandibular fractures. Compare to conventional miniplates, three dimentional plates were found more effective in terms of post operative occlusion, post operative mobility of reduced fractured segments and the degree of anatomic reduction. Objectives: Compare the conventional 2.0mm mini plates versus 3D mini plates in the fixation of isolated mandibular symphysis fractures. Study Design: Interventional study. Setting: Oral & Maxillofacial Surgery Department, Abbasi Shaheed Hospital Karachi. Period: Two years from 1st January 2013 to 2nd January 2015. Material & Methods: One hundred and fifty four patients were randomly selected and allocated into two groups. Group?I? in which patients were treated with conventional mini plates and group?II? where patients were treated with 3D mini plates. Results: Mean (+SD) age of patients was 29.53 (±7.88) years. Among 154 patients in this study, majority (75.3%) of cases had age 20 - 35 years. Majority, 124 (81.2)were males and 29 (18.8%) were females. In Group I, anatomic reduction at 3 month post-operative was observed in 30 (39%). In Group II (3D Plates) at 3 months post-operatively, ideal molar relationship was higher (89.6% Vs. 98.7%; p-value = 0.016), fracture mobility was lower (14.3% Vs. 2.6%; p-value = 0.009) and higher anatomic reduction. Conclusion: Three dimensional miniplates are more effective compared to conventional miniplates.
