Osteotomy, Le Fort I

The purpose of this study is to find out if 3D printed patient-specific titanium plates improve surgical accuracy and decrease operative time compared to milled patient-specific titanium plates in patients having Le Fort I osteotomy for jaw correction. The main questions it aims to answer are: * Do 3D-printed patient specific titanium plates improve surgical accuracy (as measured by ability to transfer the computer plan to the patient's jaw)? * Do 3D-printed patient specific titanium plates decrease operative time when compared to milled patient specific titanium plates? This study will compare two groups of patients. One group will receive 3D printed plates (study group) and the other will receive milled plates (control group) to see if the different methods of making the plates changes the surgical accuracy or operative time. All participants in the study will: * Have Le Fort I osteotomy surgery using patient specific titanium plates (either 3D printed or milled). * Have CT scans before and after surgery to evaluate accuracy. Have their operative time recorded. * Have a post-surgical follow-up to evaluate healing, stability and orthodontic treatment.
