“…This went in accordance to Levy et al [3], Frost et al [4] and Tonima et al [5] as they stated that the smaller, more flexible bone plates have minimal stress shielding effect, with less hazard effect on mineral content of bone and its mechanical properties as compared to the effect of AO plate. This went in accordance with Champy et al [7] who stated that smaller plates placed with monocortical screws in ideal osteosynthesis lines were needed to achieve healing under functional load without roots injury. And also in agreement with Potter and Ellis [8] who reported that thin malleable miniplates had minor complications.…”

“…5 Tension banding principle denotes the principle of plating along this tension line for stable internal fixation of the mandibular fracture, which is the theoretical basis for the miniplate osteosynthesis. 6 Contrary to balancing side, the working side of the functioning mandible is subject to twisting forces causing torsional stress which must be neutralized by some powerful load-bearing plate. Also called as reconstruction plate, it is applied to buttress the comminuted fractures (as a buttressing plate) or to bridge the gaps of the segmental defect caused by major facial trauma or ablative tumour surgery (as a bridging plate).…”

Working and balancing sides are subject to torsional and the tensile stresses, respectively. Tension banding principle denotes the principle of plating along the tension line for stable internal fixation on the balancing side of the mandibular fracture, which is the theoretical basis for the miniplate osteosynthesis. On the contrary, Arbeitsgemeinschaft fϋr Osteo - synthesefragen/Association for the Study of Internal Fixation (AO/ASIF) introduced the idea of stable fixation which confirms the stability of the fracture segment across the fracture line of the working side. Merging the principles of the miniplate osteosynthesis and compression osteosynthesis, the author suggests a new technique of angled eccentric osteosynthesis in case of simple mandibular fractures. The drilling holes are eccentrically positioned away from the fracture gap and intentionally angled to each other. The advancement of the miniscrews through these eccentrically angled drill holes will exert an axial load toward the fracture gap providing an interfragmental compressive force

“…Champy and colleagues determined "the ideal line of osteosynthesis" in the mandible, where miniplate fixation is the most stable [ 27 ]. In the mandibular angle region, this line indicates that a plate may be placed either along or just below the oblique line of the mandible [ 9 ].…”

Three lateral osteotomy designs for bilateral sagittal split osteotomy: biomechanical evaluation with three-dimensional finite element analysis

BackgroundThe location of the lateral osteotomy cut during bilateral sagittal split osteotomy (BSSO) varies according to the surgeon's preference, and no consensus has been reached regarding the ideal location from the perspective of biomechanics. The purpose of this study was to evaluate the mechanical behavior of the mandible and screw-miniplate system among three lateral osteotomy designs for BSSO by using three-dimensional (3-D) finite element analysis (FEA).MethodsThe Trauner-Obwegeser (TO), Obwegeser (Ob), and Obwegeser-Dal Pont (OD) methods were used for BSSO. In all the FEA simulations, the distal segments were advanced by 5 mm. Each model was fixed by using miniplates. These were applied at four different locations, including along Champy's lines, to give 12 different FEA miniplate fixation methods. We examined these models under two different loads.ResultsThe magnitudes of tooth displacement, the maximum bone stress in the vicinity of the screws, and the maximum stress on the screw-miniplate system were less in the OD method than in the Ob and TO methods at all the miniplate locations. In addition, Champy's lines models were less than those at the other miniplate locations.ConclusionsThe OD method allows greater mechanical stability of the mandible than the other two techniques. Further, miniplates placed along Champy's lines provide greater mechanical advantage than those placed at other locations.
