Accuracy of Computer Guided Screw Holes Locating Guide and Patient Specific Champy Plate vs Conventional Champy Plate Osteosynthesis in Management of Mandibular Angle Fracture: Randomized Controlled Trial

the operation will under general anesthesia with nasal intubation and oral pack, Injection of 20 cc saline adrenaline 1:00000 to 0 in the sulcus for hemostasis, Vestibular mucosal incision, Reflect the flap to visualize the broken segments. Full thickness mucoperiosteal flaps were then carefully raised to expose enough underlying alveolar bone then mobilize the broken segment , Arch bar was made to achieve proper occlusion put the Champy 2.0 plate on the ventral surface of the external oblique of the mandible and remove it for further bending using plate pliers for further accommodation of the plate then fix it in place using mono cortical screws.

"the operation will under general anesthesia with nasal intubation and oral pack, Injection of 20 cc saline adrenaline 1:00000 to 0 in the sulcus for hemostasis, Vestibular mucosal incision, Reflect the flap to visualize the broken segments.~Full thickness mucoperiosteal flaps were then carefully raised to expose enough underlying alveolar bone to accommodate the screw holes locating guide and the custom-made Champy plate.~, Put the specific screw holes locating device in place and drill the screw holes, remove the screw holes locating device and mobilize the segments then apply the custom-made Champy plate and fix it with screw for passive reduction of the segments. Then suture the mucosa."
