Area of Science:

Orthodontics and Maxillofacial Surgery
Medical Engineering
Surgical Planning Technology

Background:

Maxillofacial dysgnathia treatment necessitates precise surgical and orthodontic planning.
Current planning methods may have limitations in accuracy for complex three-dimensional jaw movements.

Purpose of the Study:

To describe a novel system for on-line presentation of jaw displacements during orthognathic surgery.
To enhance the accuracy of surgical planning for maxillofacial dysgnathia.

Main Methods:

Utilized the hexapod principle to plan operations with six degrees of freedom.
Measured three-dimensional jaw and jaw segment movements during the planning phase.
Employed routinely prepared casts for surgical simulation and recorded planned displacements.

Main Results:

The hexapod system allows for detailed planning of jaw movements in six degrees of freedom.
Three-dimensional jaw movements were accurately measured during the planning stage.
Achieved superior accuracy in surgical planning compared to intra-operative methods.

Conclusions:

The described hexapod system significantly improves the accuracy of orthognathic surgical planning.
This technology offers a more precise method for managing maxillofacial dysgnathia.
The system provides a valuable tool for orthodontic surgeons, enhancing pre-operative planning and potentially patient outcomes.
