Precise control of maxillary multidirectional movement in Le Fort I osteotomy using a surgical guiding device

We introduced a surgical protocol to achieve accurate maxillary multidirectional movement in Le Fort I osteotomies. This comprised a way of controlling precision and a guiding device together with prebent titanium plates. We evaluated the protocol using a semiautomated 3-dimensional assessment in 22 patients with maxillary multidirectional movement (movement in three or more of six directions). Operations were all done between October 2015 and April 2017 by the same surgeon, who followed the protocol strictly.
