Abstract
Aim: Evaluation of changes in intercondylar distance, intercondylar angle and other clinical outcomes regarding intra-operative time, mobility of fractured segments and need for elastics guidance while using Three-dimensional miniplates versus conventional 2.0 mm miniplates in the treatment of anterior mandibular fractures. Methodology: It is a controlled comparative clinical trial on 30 patients with anterior mandibular fractures who were treated in the study group (15 patients) using 3D miniplate fixation and in the control group (15 patients) using Champy{u2018}s miniplates. Patients were randomly divided into either control or study group using opaque sealed envelopes. On the most representative cut of an axial computed tomography showing both right and left condyles in their largest and defined mediolateral diameter, the medial and lateral poles were marked. This marking allowed measuring of intercondylar distance, furtherly determination of condylar axis which is mandatory for measuring intercondylar angle as it results at the intersection of the right condylar axis and left one. Intra-operative time assessed using stopwatch. Results: Parasymphyseal fractures in the study found to be of higher incidence than symphyseal fractures. The main cause of mandibular fracture in this study was Road Traffic Accidents representing (80%) followed by Inter Personal Violence (13.3%) then Fall from Height (6.7%). 3D miniplate osteosynthesis needed less time than two miniplates osteosynthesis with a difference around (8.4 min.) which is statistically significant of P value (0.012). Overall (pre-operatively to 3 months postoperative), 3D plate osteosynthesis recorded less median percent increase in intercondylar distance than two miniplates osteosynthesis
