Background: In orthognathic surgery, virtual planning is gradually taking over in clinical practice. To start with, virtual surgery planning (VSP) is believed to be less time-consuming and less expensive than conventional surgery planning (CSP). Moreover, the improved visualization of craniofacial deformities, such as occlusal canting and asymmetries, is a further advantage. Aim: To assess the result of Le Fort I osteotomy using CAD/CAM and 3Dcustomized titanium plate with virtual planning in orthognathic surgery. Materials and Methods: 8 patients with vertical maxillary excess will be included in the study. Le Fort I osteotomy using CAD CAM surgical guide and 3Dcustomized plate will be done for the study group. All patients will be followed clinically and radiographically for one month.

Le Fort I osteotomy will be performed with the aid of a surgical guide through the mucosal incision at the maxillary vestibule region, providing adequate surgical exposure. The planned position will be obtained using a customized titanium plate for precise maxillary position and fixation as planned virtually on the software.

Change in pain
pain will be scored using visual analogue scale. it ranges from 0 to 10, 0 mean no pain and 10 means severe pain
Time frame: 2nd and 7th days
change in edema
it was evaluated by its ability to pit. The examiner's fingers will press into the dependent area for 5 seconds, and the pitting will be graded on a scale of +1 to+4.
Time frame: 2nd and 7th days
Change in post operative osteotomy position
Computed tomography (CT) will be used immediately postoperative to assess surgical position by comparing the clinical results with the virtually planned outcome.
Time frame: Immediate post operative
