Main Methods:

  • Development of a simplified protocol for 3D virtual simulation.
  • Image segmentation and creation of a composite skull.
  • Condylar position control and sequencing of bimaxillary surgery.
  • Protocol implementation without specialized apparatus or software.

Main Results:

  • The protocol was successfully applied in approximately 2000 cases (2015-2022).
  • The method has gained popularity among local surgeons.
  • Preliminary studies indicate accuracy standards suitable for clinical use.

Conclusions:

  • The described protocol offers a simplified and accessible approach to 3D virtual simulation for orthognathic surgery.
