Le Fort; I
Conditions
Brief summary
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.
Interventions
PROCEDURELe Fort I osteotomy using CAD CAM surgical guide and 3Dcustomized plate
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in pain | 2nd and 7th days | pain will be scored using visual analogue scale. it ranges from 0 to 10, 0 mean no pain and 10 means severe pain |
| change in edema | 2nd and 7th days | 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. |
| Change in post operative osteotomy position | Immediate post operative | Computed tomography (CT) will be used immediately postoperative to assess surgical position by comparing the clinical results with the virtually planned outcome. |
