The Use of Combined Microplate And Miniplate in the Fixation of the Mandibular Fractures (A Randomized Clinical Trial)

The study group patients have been treated with 1.6 microplates at the superior border and 2.0 miniplate at the inferior border to evaluate its efficacy in the fixation of symphyseal and parasymphyseal fractures using this technique. The control patients were treated with two 2.0 plates. The stability was assessed using computed tomography immediately performed postoperatively and after 6 months. Assessment of the change in the intercanine distance using the Student T test was statistically Non Significant (P value 0.34). The change of intercanine distance in the study was 0.04 +/- 0.05 mm, compared with that of the control, which was 0.01 +/- 0.03 mm. Assessment of change in intermental foramina distance was statistically NS (P value = 0.06). The average difference in intermental foramina distance in the study was 0.04 +/- 0.05 mm, compared with the control, which was 0.002 +/- 0.004 mm. Based on the findings of the current study, the authors recommend the use of microplates combined with miniplates in the correction of both symphyseal and parasymphyseal fractures successfully.
