Customized plate fixation
maxillomandibular fixation
Customized Plate fixation of Vertical Ramus Osteotomy after Mandibular Setback - intervention: All cases will undergo one surgery under general anesthesia. Incision was made medial to external oblique ridge from the asendindg ramus to second molar region The intraoral vertical osteotomy is accomplished by using an oscillating saw to make the cut from the sigmoid notch through the inferior border of the mandible. 3D virtual planning and 3D mandible model represented fom CBCT in MIMICS The customized fixation plate is positioned to fix the proximal and distal segment together
Mandibular Setback by Vertical Ramus Ostotmy fixed with Maxillomandibular fixation - intervention: All cases will undergo one surgery under general anesthesia incision was made medial to external oblique ridge from the asendindg ramus to second molar region . The intraoral vertical osteotomy is accomplished by using an oscillating saw to make the cut from the sigmoid notch through the inferior border of the mandible. Patient is placed in maxillomandibular fixation (MMF) using a prefabricated occlusal splint
