A surgical extra-oral incision was made 2 cm below the inferior mandibular margin, at the angle. A blunt dissection to reach the mandibular border and a subperiosteal dissection of the masseter muscle were performed. Osteotomy line was marked on the mandible outer cortex; the device was correctly positioned and fixed with four monocortical screws. The steps were repeated on the other side. The devices were then removed, a deepening of the osteotomy line with a fissure bur was produced and the osteotomy was completed, applying a rotational force with a chisel. Care was applied when opening the ostectomy site to preserve the alveolar nerve. The devices were re-fixed to the mandible using the same screw holes and assessed for stability (Figure ). The skin was dissected anteriorly to the surgical incision, allowing the activation bar to merge from the skin. The devices were activated immediately (2 mm) with no latency period and the integrity of the infe...
