Objective
The objective of this study was to evaluate the efficacy of a novel tooth/bony-supported
virtual splint design to control the maxillary vertical, rotational, and anteroposterior
intraoperative movements.
Study Design
A tooth/bone-borne splint was designed to position the osteotomized maxilla intraoperatively.
Lateral cephalometric radiographs were obtained 1 week before the operation and 1
week after to compare the planned and actual movements of the maxilla.
Results
The paired t test showed no significant difference between the planned and actual movements in
both the vertical and horizontal measurements (P ≤ .05). The difference between the planned and actual horizontal movements in 4 (66.7%)
of the 6 patients was 1 mm or less. For the vertical movements, 5 (83.3%) of the 6
patients showed a difference equal to or less than 1 mm.
Conclusions
The 2-piece surgical stent showed accurate control on the osteotomized maxilla and
succeeded its repositioning to the preplanned positions.
