Purpose: This study aimed to compare radiographically and clinically the single 3-D miniplate and the conventional two
miniplates in ORIF of anterior mandibular fractures.
Materials and Methods: Thirty patients with isolated anterior mandibular fractures were randomly divided into 2 equal
groups. ORIF was accomplished in the study group using single 3D miniplates and in the control group using two conventional
miniplates. All patients were radiographically evaluated using OPGs and Multislice CT scans (preoperative, immediately and
at 3 months postoperative) to assess condylar position regarding (intercondylar distance and intercondylar angle). Clinical
parameters evaluated were intraoperative time, occlusion and rigidity of fixation.
Results: Functionally successful osteosynthesis had been achieved in both groups. The 3D miniplates required statistically
significant less intraoperative time than the two miniplates. The 3D miniplates recorded less intercondylar distance and higher
intercondylar angle than the two miniplates although the difference was statistically insignificant.
Conclusion: The quadrangular geometry of the 3-Dimensional miniplate guarantees comparable fixation rigidity and segment
stability and accordingly should be considered an alternative for ORIF of anterior mandibular fractures with the superior
advantage of reduced operative time. The 3-Dimensional miniplates provided superior restoration of post-operative condylar
position and inter-condylar distance compared to the conventional two miniplates although the difference was statistically
insignificant.
