Use of a single 2.0-mm locking AO reconstruction titanium plate in linear, non-comminuted, mandible fractures

Abstract

Purpose:The aim of the following study is to prospectively evaluate the use of a single Arbeitsgemeinschaft für Osteosynthesefragen (AO) 2.0-mm locking reconstruction plate for linear non-comminuted mandibular fractures without the use of a second plate.Materials and Methods:This study consisted of a sample of 10 patients who reported to the department with fractures of the mandible and were treated over a period of 24 months from November 2010 to November 2012. Out of these, there were 8 male patients and 2 female patients. There were four cases of isolated parasymphysis fractures, 1 of the case had a parasymphysis fracture associated with subcondylar fracture, 4 had a body fracture and 2 had a symphysis fracture.Results:All patients had satisfactory fracture reduction and a successful treatment outcome without major complications. Only one patient (10%) developed minor complications.Conclusion:The study has demonstrated that treating linear non-comminuted mandibular fractures with a single AO 2.0-mm locking reconstruction plate provides excellent stability at the fracture site which in turn leads to sound bone healing and early functional rehabilitation.

Single 2.3 Reconstruction Plate Versus Two Miniplates in the Treatment of Mandibular Fractures (Randomized Clinical Trial)

“…However, given the presence and location of facial lacerations, an extraoral approach was used to extend the primary wound to provide minimal surgical access and expose all fractures for fixation, registered by Kanno et al, (8). The AO/ASIF technique, which uses a single low-profile reconstruction plate placed near the inferior border and has recently been shown to provide excellent stability, was used in Group A (1,8,11,20,21). Group B, on the other hand, was treated using Champy's principles of application, with many authors reporting high success rates (3,(34)(35)(36).…”

“…Maxillofacial surgeons have always had a difficult time dealing with maxillofacial trauma. As a result, numerous studies are frequently conducted to improve on established techniques and materials used over time (1). Uninterrrupted recovery, and instant rehabilitation of performance and form with no InterMaxillary Fixation (IMF) period are the ambitious goals in managing mandibular fractures according to Swiss Association for Study of Internal Fixation (AO/ASIF) (1)(2)(3).…”

“…The thickness of a standard miniplate is 1.0mm, whereas the thickness of a reconstruction bone plate ranges from 1.5 mm to 3.0 mm (9). Besides that, one low-profile reconstruction plate near the mandible's inferior border appeared to be obviating the usage of a second plate as it is capable of resisting tension and compressive forces (1,10).…”

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

“…Re-establishment of previous normal tension (alveolar border) and compression (basal portion) of functional bone trajectories is the fundamental prerequisite for the full recovery of the mechanical integrity of the mandible [15][16][17][18]. A disadvantage of conventional bone plate/screw systems is that the plate must be perfectly adapted to the underlying bone to prevent alterations in the alignment of segments and changes in occlusal plane.…”

“…Other studies report favorable results with the 2.0 mm titanium miniplate system [14]. According to Arbeitsgemeinschaft für Osteosynthesefragen (AO)/Association for the Study of Internal Fixation (ASIF) principles, the main objective of open reduction and rigid internal fixation in the management of mandibular fractures is to achieve undisturbed healing and immediate restoration of form and function without the adjunctive use of maxillomandibular fixation (MMF) [15][16][17][18]. To overcome this problem, the concept of locking bone plates was introduced.…”
