Orthognathic surgery has traditionally been used to correct dentofacial deformities. Conventional methods rely on 2D radiographic images, occlusal splints, and dental casts, but these approaches have limitations, such as errors during face-bow transfer. Technological advancements, including 3D imaging, virtual surgical planning (VSP), and computer-aided design and manufacturing (CAD/CAM), have improved the precision and outcomes of orthognathic surgery.

This study included one group of patients need orthognathic surgery and fixation of maxilla using custom made plate designed by 3D virtual planning using Materialize mimic soft ware
