Area of Science:

  • Oral and Maxillofacial Surgery
  • Orthognathic Surgery
  • Piezoelectric Surgery

Background:

  • Le Fort I osteotomy allows complex maxillary repositioning but carries risks of complications due to interradicular osteotomy.
  • Existing techniques for maxillary segmentation face challenges regarding safety and precision.

Purpose of the Study:

  • To describe a standardized, safe protocol for maxillary segmentation using piezoelectric technology.
  • To detail an H-pattern osteotomy technique for improved surgical control and reduced complications.

Main Methods:

  • Utilized piezoelectric technology for controlled bilateral segmentation between canine and lateral incisor.
  • Employed an H-pattern osteotomy to create mobile segments, including an anterior premaxilla and intermediate bony island.
  • Integrated direct visualization of the nasal floor and progressive deepening toward the palatal cortex.

Main Results:

  • Systematic application since 2014 demonstrated improved surgical control and preservation of bone vascularization.
  • Reduced incidence of periodontal and dental injuries compared to conventional methods.
  • Achieved safe, reproducible, and efficient maxillary segmentation.

Conclusions:

  • Protocolized maxillary segmentation with piezoelectric technology offers a safe and effective approach for Le Fort I osteotomy.
  • This technique optimizes outcomes in complex orthognathic surgery by minimizing risks and enhancing precision.
  • The described H-pattern osteotomy facilitates independent segment mobilization and superior surgical management.
