The investigator will assess the inverted sequence approach in the treatment of class III patient undergoing bimaxillary orthognathic surgery
The investigator will compare the maxillary stability in class III orthognathic patients undergoing bimaxillary surgery by two surgical approaches ; the mandible-first (intervention) and the maxilla-first (control)
