No results posted yet for this study

Summary

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.

Conditions

  • Dental Deformity
  • Malocclusion
  • Orthognathic Surgery

Interventions

DEVICE

Conventional fixed orthodontic appliances

Orthodontic preparation with fixed multi-bracket appliances in place at the time of surgery, providing conventional anchorage for intermaxillary fixation and intraoperative occlusal control.

DEVICE

Clear aligner therapy

Orthodontic preparation with clear aligners and no fixed brackets at the time of surgery. Alternative intraoperative strategies may be required to achieve planned occlusal positioning and stabilization.
