Abstract

Objective: The objective of this study was to evaluate the efficacy of a new bony/bony-supported virtual splint design to control the maxillary vertical, rotational, and anteroposterior intraoperative movements.Material and methods: 12 patients need le fort I osteotomy were divided into 2 equal groups randomly. In the study group A, bone/bone-borne splint was designed to position the osteotomized maxilla intraoperatively. Lateral cephalometric radiographs were obtained before the operation and 1 week after to compare the planned and actual movements of the maxilla. In the controlled group conventional splint was designed.Results: The rapid protyped template showed deviation for the planned position with a value less than 1 mm. while the conventional stent show deviation for the planned position with a value less than 1.5 mm.Conclusions: The results of the current study demonstrate a good control over the maxillary movements with both splint designs in both vertical and horizontal planes.
