This study introduces a computer-assisted three-dimensional virtual osteotomy system (CAVOS) for orthognathic surgery. It enables surgeons to plan and predict bony segment movements in a virtual reality environment before the actual operation.

Area of Science:

  • Medical Technology
  • Computer Science
  • Surgical Planning

Background:

  • Orthognathic surgery requires precise planning to correct jaw deformities.
  • Traditional surgical planning methods can be limited in visualizing complex 3D bony movements.

Purpose of the Study:

  • To present a novel computer-assisted three-dimensional virtual osteotomy system (CAVOS) for orthognathic surgery.
  • To evaluate the utility of virtual reality in surgical planning and pre-surgical prediction.

Main Methods:

  • Development of a computer-assisted three-dimensional virtual osteotomy system (CAVOS).
  • Utilizing a virtual reality workbench for immersive surgical planning.
  • Employing a 3D mouse as a virtual scalpel for manipulating 3D bony models.
  • Simulating virtual surgery on computer-generated 3D head models.

Main Results:

  • The CAVOS system allows surgeons to immerse in a virtual reality environment for planning.
  • Pre-surgical prediction of 3D bony segment movements is achievable.
  • Virtual surgical simulations can be visualized from any arbitrary viewpoint.

Conclusions:

  • The computer-assisted three-dimensional virtual osteotomy system (CAVOS) offers a powerful tool for orthognathic surgery planning.
  • Virtual reality enhances the visualization and prediction capabilities for complex surgical procedures.
  • This technology has the potential to improve surgical outcomes in orthognathic procedures.
