Area of Science:

  • Oral and Maxillofacial Surgery
  • Orthognathic Surgery
  • Biomedical Engineering

Background:

  • Large mandibular setbacks present surgical challenges.
  • Accurate planning is crucial for achieving desired outcomes in orthognathic surgery.
  • Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM) technologies offer precision in surgical guides.

Observation:

  • A case report details a patient requiring substantial mandibular setback.
  • The surgical approach utilized a mandibular step osteotomy.
  • A custom CAD/CAM-derived wafer was employed to guide the osteotomy and fixation.

Findings:

  • The mandibular step osteotomy facilitated a significant mandibular setback.
  • The CAD/CAM wafer ensured precise execution of the planned osteotomy and repositioning.
  • Successful arch reduction was achieved concurrently with the mandibular setback.

Implications:

  • Mandibular step osteotomy is a viable technique for complex mandibular deformities.
  • CAD/CAM technology enhances accuracy and predictability in orthognathic procedures.
  • This approach offers a solution for combined mandibular setback and arch length discrepancy.
