Study of Efficacy and the Comparison Between 2.0 mm Locking Plating System and 2.0 mm Standard Plating System in Mandibular Fractures

Abstract

Purpose The purpose of this study was to evaluate the efficacy and comparison between 2.0 mm locking plate system and 2.0 mm Champy's titanium mini plating system in mandible fractures. Materials and Methods A total of 20 patients with mandibular fractures were selected and divided into two groups A and B on randomized basis. Group A was treated with open reduction internal fixation using 2.0 mm locking plates and group B with 2.0 mm Champy's titanium miniplates. All patients were followed up for 12 weeks postoperatively.Results Results of the study show less screw loosening, less precision in plate adaptation and less alteration of the osseous or occlusal relationship upon screw tightening in group A. Chi square test was applied to compare the results between the two groups. Statistical analysis did not show significant difference of incidence of malocclusion between the two groups (p value = 0.606). Statistical analysis using un-paired t test showed significant difference of working time between the two groups (p value = 0.00296). When comparing the overall complication rates according to plates used, the v 2 test showed no statistically significant difference between the locking and nonlocking plates (p [ 0.05).Conclusion It is observed in our study that the locking plate/screw system offers significant advantages over the conventional plating system. The precise adaptation required for using conventional plates is not needed when this locking plate/screw system is used. Locking plate/ screw system provides better stability than the conventional plate/screw system.

Comparison of Transosseous Wiring and Miniplates in Management of Mandibular Parasymphyseal Fractures

“…12,13 The advantage of open reduction and internal fixation include early restoration of occlusal function and proper repositioning of fracture with more stable and predictable results. 14 Complications associated with miniplates and transosseous wiring includes infection, malocclusion, mal-union, non-union, nerve damage and TMJ-dysfunction. 15 Of these complications, postoperative infection and malocclusion was 15% and 10% after transosseous wiring 13 and 1.5% and 0.2% after miniplate osteosynthesis, 16 respectively.…”

Complications of locking and non-locking plate systems in mandibular fractures

“…In 16 studies [10][11][12][13]22,[24][25][26][27][28][29][30][31][32][33][34] , 2.0-mm locking plates were compared with a 2.0-mm non-locking plate system. In two studies, a 2.0-mm locking plate, and three-dimensional (3D) locking plate were compared with double 2.0-mm non-locking Plates 35,36 .…”

“…In two studies 33,39 , the condylar fractures were treated with open reduction and internal fixation (ORIF), and four studies 13,23,28,41 did not report whether the condylar fractures were treated with ORIF or closed. In 10 studies [10][11][12]22,26,30,32,34,38,46 , condylar fractures were excluded and 10 studies 25,27,29,35,36,40,42,[47][48][49] did not report whether these fractures were included or not. In the studies that included mandibular fractures concomitant with another mandibular fracture (bilateral or double unilateral), the concomitant fracture was fixated with non-locking 2.0-mm plates.…”
