This randomized comparative study evaluates the accuracy and feasibility of two techniques for maxillary repositioning in Le Fort I osteotomy: Customized titanium plates (splintless technique) Three-dimensional (3D)-printed intermediate splints Participants (n = 12) aged 18-30 years with dentofacial deformities will be equally divided into two groups: Group I: Osteotomy guided by patient-specific surgical guides, fixed with pre-bent customized titanium plates. Group II: Osteotomy guided by 3D-printed intermediate splints with conventional fixation. Primary Outcome Accuracy of maxillary repositioning (measured as millimeter \[mm\] deviation from the virtual surgical plan), assessed via computed tomography (CT) superimposition using Mimics software at one week postoperatively. Secondary Outcomes Operative time Fabrication accuracy of the customized titanium plate and 3D-printed splint Postoperative complications (e.g., infection, plate failure) Hypothesis Customized titanium plates will reduce maxillary positioning errors and operative time compared to 3D-printed splints. Relevance This study may validate splintless techniques for improved precision in orthognathic surgery.
