Abstract
Purpose: In the present study, we evaluated the difference between the model surgery movement and
the actual surgical movement in the horizontal (X), vertical (Y), and transverse (Z) directions using the
same reference coordinates.
Patients and Methods: Twelve patients (6 male and 6 female, mean age of 24.3years) who underwent
Le Fort I osteotomy and sagittal split ramus osteotomy were included in the study. The maxillary position
was controlled by an intermediate splint and face-bow/bite-fork combination system. A coordinate
transformation system with transition matrices was developed, which enabled objective comparison
between the planned surgical change of the maxilla on the articulator and the actual surgical change
assessed by the 3-dimensional cephalogram.
Results: The absolute mean difference was 2.2 mm. The difference between the model surgery and the
surgical result ranged from 7.7 mm to 6.6 mm. The surgical result differed from the planned surgical
movement by more than 2 mm in more than 45% of the measured coordinate values.
Conclusion: Although all of the patients were satisfied with their postsurgical appearance and occlusion,
the result shows that further development is required in the maxillary positioning system.
