Champy's lines of ideal osteosynthesis pdf files

Using a simple cantilever beam model, champy et al 5, 6 showed that the superior mandibular border was subjected to tension and splaying, and the inferior border was subjected to compression. Plates placed along ideal lines of osteosynthesis were thought to provide optimal fixation and stability. Management of mandibular fractures part 2 free download as powerpoint presentation. An angled screw application will allow plating via preferred intraoral approach. Champy later performed a series of experiments with miniplate that delineated ideal lines of osteosynthesis within the mandible. Plates placed along these lines were thought to provide optimal fixation and stability figure 1.

Champy versus ao for mandible fractures full text view. Inner square screw inner square screw inner square screw inner square screw inner square screw inner square screw inner square screw inner square screw inner square. Ideal plate placement for angle fractures was along the superior border of the mandible above or just below the superior oblique ridge. Patients will either be treated with small 2 mm plates and screws according to champy principles or a modified champy technique that utilizes additional 2mm platesscrews or larger platesscrews 2. Champy s ideal lines of osteosynthesis masticatory muscles produce tension at upper border and compression at lower border torsional forces produced anterior to the canines 102. These techniques contradicted the ao and luhrs emphasis on compression and absolute rigidity. All patients will have orif of their fractured mandible under general anesthesia. Pdf single miniplate osteosynthesis in angle fracture. All the cases were treated successfully, common complications which we have observed in this study, cosmetic disfigurement, delayed union, infection, wound dehiscence and paresthesia. Mandibular fractures are treated surgically by either rigid or semirigid fixation, two techniques that reflect almost opposite concept of craniomaxillofacial osteosynthesis.
