This is a case with history of traumatic accident to the face which caused Lefor I fracture + nasal bone fracture + multiple fractures of both arches + inrusive displacement of front teeth. Thanks to my dear friend @drkianiofficial for taking care of all surgical procedures which includes fixation of Lefort I and multiple fractures within the arches + nasal bone repair simultaneously and reffering the case for post surgical orthodontic force eruption of front teeth. Cantilever spring with double extrusive helix anchored to the surgical screw used to apply extrusive force to the front teeth. Take note on 👉👉 1.The distance of helix to the achorage unit (surgical screw), 2. Orientation of helix and 3.The distance of spring hook to the upper central incisor before activation which are the 3 key points of spring design
