Design outcomes

Primary

Measure	Time frame
Accuracy of maxillary repositioning measured as the linear difference between the preoperative virtual surgical planning plan and the postoperative skeletal position in anterior and vertical dimensions. Timepoint: Three months after surgery. Method of measurement: Linear measurements in millimeters comparing the preoperative virtual surgical planning model with the postoperative cone beam computed tomography image in anterior and vertical dimensions.	—

Secondary

Measure	Time frame
Linear measurement of bone contact at maxillary buttresses after Le Fort I osteotomy, recorded in millimeters on postoperative CBCT. Timepoint: Three months after surgery. Method of measurement: Linear bone contact is measured on postoperative cone-beam computed tomography using a standardized imaging protocol.	—
