Conventional 2.0 mm miniplates versus 3-D plates in mandibular fractures

Abstract

Aim:To compare and evaluate the treatment outcome and postoperative complications in mandibular fractures using 2- and 3-dimensional miniplates.Materials and Methods:This study consisted of a sample of 28 patients (40 fracture sites) divided randomly but equally (single-blind control trial study) into two groups. Each group contains 14 patients (20 similar fracture sites in each group). Group 1 was treated with open reduction and internal fixation using 3-dimensional (3-D) miniplates. Group II was treated using 2-dimensional (2-D) 2-mm miniplates.Results:Out of 14 patients treated by conventional 2-mm miniplates, 2 patients developed occlusal discrepancy, another 2 had postoperative mobility at fracture site, and 1 developed plate failure and subsequent infection, which was treated by removal of the plate under antibiotic coverage. One patient treated by 3-dimensional plates had tooth damage.Statistical Analysis:Chi-square test.Conclusion:The results of this study suggested that the treatment of mandibular fractures (symphysis, parasymphysis, and angle) with 3-dimensional plates provided 3-dimensional stability and carried low morbidity and infection rates. The only probable limitations of 3-dimensional plates were excessive implant material due to the extra vertical bars incorporated for countering the torque forces.

“…Similar results are presented by Arcuri et al [78] and Domanski et al [79]. Regardless of dubious effectiveness, 2D plates is reported, for example, by Sadhwani and Anchlia, who argue that the use of 3D plates results in correct 3-dimensional stability of the fracture and enhances the resistance to undesirable forces [119]. They also report that better stabilization of bone fragments with the 3-dimensional plates reduces the number of infectious complications in the postoperative period.…”

Computer-Assisted Surgery in Management of Mandibular Fracture Using a Custom-Made Titanium Mesh Tray

“…The titanium mesh gives the fracture line a significantly better stability than the conventional miniplates, owing to its excellent physical and biomechanical properties along with the presence of extra vertical support that effectively counter torque forces from acting on the fracture line, thus decrease the probability of fracture line infection, mal-union or non-union (9,13). Furthermore, the mesh's malleablility, semi-rigidity and lack of elastic memory features, prevent subsequent stress shielding in the fractured area (14).…”

The use of three-dimensional strut plates for the management of mandibular angle fractures: a retrospective analysis of 222 patients

“…7,17,[25][26][27] All patients in the present study had their archbars and IMF removed at the conclusion of the case. Patients were allowed to consume a nonchewing soft diet post-surgery for 6 weeks.…”

“…Therefore the greater bulk of soft tissue can be surmised to decrease the risk of wound breakdown and plate exposure. 1,23,27,29 Nine patients developed postoperative trismus based on clinically measured inter-incisal distances. None of the patients had a limited mouth opening after 3 months.…”
