This retrospective single-center observational study compared perioperative and early postoperative outcomes in patients undergoing orthognathic surgery after orthodontic preparation with either conventional fixed brackets or clear aligners. The objective was to assess whether aligner-based preparation was associated with differences in intraoperative occlusal management, including fixation stability, technical difficulties, need for additional intraoperative adaptations, and early occlusal outcomes.
