A 28-year-old male patient presented to a clinic on the 2nd day after the face trauma and complained of bilateral mandibular pain, difficult swallowing and obstructed breathing. Objectively: there was a slight swelling in the region of the molars on both sides, the teeth were intact but the jaw fragment with the 43, 42, 41, 31, 32, 33 teeth deviated downward and backward. Manual reposition didn't produce any positive result. Which appliance should be used for treatment?
