“…Biomechanical studies have shown that ipsilateral molar loading causes lower border splaying with Champy's technique. 2,3 Also, in vitro studies point out the greater stability of two point fixation (2 bone plates) in angle fractures as compared to one. 4 However, clinical studies provide a different picture.…”

“…SaiKrishna et al [13] assessed both systems on a clinical study and found the locking plate/screw system to be more rigid than conventional plate/screw system reducing the need and duration of IMF. In a prospective study by Cawood, 5.7 % of mandibular fractures excluding additional condylar neck fractures treated by miniplate osteosynthesis had malocclusion detected on review [15] and other study reported a 4.8 % malocclusion rate in their group treated by miniplate osteosynthesis [4]. Seemann et al [16] assessed both types of plating systems in condylar fractures and found that locking plates were more likely to break and non-locking plates showed screw loosening.…”

To compare and evaluate the effectiveness of 2.0 mm locking miniplates versus 2.0 mm standard miniplates in treatment of mandible fractures. Sixty randomly selected patients who sustained mandibular fractures were selected for this study. The fractured fragments were stabilized using 2.0 mm locking miniplates in 30 cases and in the remaining 30 cases the fractured fragments were fixed with conventional 2.0 mm miniplates. Post-operative stability was assessed with radiographs at 7th day, 1st, and 3rd months. The stability of the reduced fracture was assessed clinically and both the types of plates were assessed with an OPG or conventional radiographs. This study shows favorable results on use of locking miniplates in mandibular fractures. The results show that there were no significant differences in the post-operative complications between the conventional and the locking plate/screw mandibular systems. The locking plate/screw system was more rigid than conventional plate/screw system, thereby reducing the need and duration of intermaxillary fixation (IMF).

“…Three-dimensional (3D) numerical [26, 27] and experimental [28] models often lead to questions about the prevailing lever-based (tot/cob) stress distribution dogma. However, those previous criticisms involve the location of occlusal forces; the focus of this paper is on the direction of those forces.…”

Objectives. The purpose of this analytical study was to examine and critique the engineering foundations of commonly accepted biomechanical principles of mandible fracture repair. Materials and Methods. Basic principles of static equilibrium were applied to intact and plated mandibles, but instead of the traditional lever forces, the mandibles were subjected to more realistic occlusal forces. Results. These loading conditions produced stress distributions within the intact mandible that were very different and more complex than the customary lever-based gradient. The analyses also demonstrated the entirely different mechanical environments within intact and plated mandibles. Conclusions. Because the loading and geometry of the lever-idealized mandible is incomplete, the associated widely accepted bone stress distribution (tension on top and compression on the bottom) should not be assumed. Furthermore, the stress gradients within the bone of an intact mandible should not be extrapolated to the mechanical environment within the plated regions of a fractured mandible.
