Clinical efficacy of three plating systems in management of mandibular parasymphyseal fractures: a retrospective study

Abstract

Abstract Background The main goal of management of the mandibular fracture is to obtain the pre-injury contour of the bone and pre-injury occlusion as well as regain function early. For Parasymphyseal fractures, the ideal fixation method is still debatable. It could range from rigid to semi-rigid fixation. The current study aimed to compare the clinical and radiographic effect of two miniplates, 2.3 high-profile Miniplates, and three-dimensional (3D) Miniplates for internal fixation treatment of mandibular para-symphyseal fractures. Methods The study reviewed 240 medical records, dividing 60 patients into three treatment groups: Group I (25 patients received 2.0 mini plates), Group II (22 patients received 2.3 high profile miniplate), and Group III (13 patients received 3D miniplate). Data included demographics, fracture diagnosis, radiographs, maxillomandibular fixation use, surgical time, intervention, postoperative stability, and complications. Results The present study included 60 patients with mandibular parasymphyseal fractures, divided into three treatment groups: Group I (n = 25, 41.67%), Group II (n = 22, 36.67%), and Group III (n = 13, 21.67%). The study found no significant differences in age and sex distribution among the three groups, but the mean surgery time varied significantly. Group II had the highest rate of complications at 22.73%, followed by Group I at 20% and Group III at 7.69%. Conclusion In conclusion, the (3D) Miniplates could provide better internal fixation treatment of mandibular para-symphyseal fractures in terms of easy use, short surgery time and less complication such as malocclusion and infection.
