Abstract

This biomechanical study investigated the effectiveness of fixation devices of simulated angle fractures in sheep mandibles. The fractures were stabilized by a Leibinger® 8-hole three-dimensional (3-D) plate, a Synthes® eight-hole mesh plate, and a Synthes® six-hole reconstruction plate with 2.0-mm and 2.4-mm mono- and bicortical screws. Each mandible was tested in bending (class III cantilever model). The bone mineral density of the mandibles was measured by computed tomography scan. The Leibinger 3-D plate showed plate deformation in bending of <230 N. None of the plates showed failure in the bone/screw interface. The gap and displacement values for the mesh and 3-D plate were comparable to those of the reconstruction plate. These results indicate that a 3-D or mesh plate can be used for fixation of mandibular angle fractures.

      Moreover, fractures on this location present the highest complication rates amongst all mandibular fractures, despite all the advancements on internal fixation (Passeri et al., 1993; Ellis and Sinn, 1993; Ellis, 1993, 1999; Ellis and Walker, 1994, 1996; Schierle et al., 2013; Feller et al., 2003; Vineeth et al., 2013). Although there are obvious differences related to surgical access, size and type of fixation devices, the basic goals for all fixation techniques are the same: early return to function and enough stability for adequate osseous repair (Wittenberg et al., 1997). In order to minimize the extent of surgery and failure of the monocortical systems, as well as to avoid extra-oral approaches, the grid plates have been developed for the application on maxillofacial trauma and orthognathic surgery.
