A comparision of 3-dimensional and standard miniplates fixation in the management of mandibular fractures

Purpose: To compare and evaluate 3-dimensional (3D) and conventional 4-hole miniplates fixation in the management of mandibular fractures. Materials and Methods: In 20 randomly selected patients who sustained mandibular fractures were selected for this study. Of the 20 cases, in 10 cases fractured fragments were stabilized using 2.0mm 3-Dimensional miniplates and in remaining 10 cases the fractured fragments were fixed with conventional 2.0mm miniplates. Post operatively cases were assessed clinically and radiographically at immediate post op, 1month and 3months. Results: This study suggests that fixation of mandibular fracture with 3D Plates provide three dimensional stability and carries low morbidity and infection rates. The only probable limitation of these plates may be excessive implant material due to the extra vertical bars incorporated for countering the torque forces and in cases where the fracture line passing through the mental foramina region. Conclusion: The 3D plate was found to be standard in Profile, strong yet malleable, facilitating reduction and stabilization at both the Superior and inferior borders giving three dimensional stability at fracture site. They seem to be an easy to use alternative to conventional miniplates. But the small sample size and limited follow up could be considered as the limitations of our study.
