Abstract Aim: The purpose of this study was to evaluate the stability and compare the outcome of the open reduction and internal fixation of the parasymphyseal mandibular fracture when using a combination one microplate and one miniplate versus two miniplates. Material and methods: this was conducted on sixteen patients with isolated parasymphyseal mandibular fracture; they were divided randomly into 2 study groups, group I was managed by ORIF using two 2.0mm miniplates while group II was managed by ORIF one 1.2mm microplate at the subapical region and one 2.0mm miniplate at inferior border. A control group consisted of 40 healthy individuals to maximum biting force of the Egyptians. The bite force was recorded for the study groups at 1week, 1 month and 3 months postoperative visits. Also the fracture stability, occlusion, plate palpability and wound healing were evaluated and any complications were recoded. Results: The mean bite force for the control group was 385 N ±219, 78.2 N±4.8, and 340.6 N ±195.4 at the right molar region, incisor region, and left molar region respectively. Regarding there was statistically non significant difference between the study groups at the different follow up visits and the bite force of group I&II was comparable to the control group. The fracture stability of both groups was optimal, one patient in group I suffer from mild occlusal derangement, one case of paresthesia and two cases of plate palpability in group I |
