摘要: Purpose The purpose of this study was to assess the transverse displacement and angulation proximal segment after a bilateral intraoral vertico-sagittal ramus osteotomy (IVSRO) its relation with mandibular setback. Patients Methods Sixty patients were recruited into underwent setback IVSRO wire fixation. Posteroanterior lateral cephalometric radiographs obtained 1 month before surgery. segments surgery measured on posteroanterior radiographs, via best-fit method. correlation amount also assessed. Results A statistically significant increase seen in intergonial width (P Conclusions This suggested that leads an inter-ramus width, as well outward condylar fragment. In addition, there between medial angles.
