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. 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. The results of the current study demonstrate a good control over the maxillary movements with both splint designs in both vertical and horizontal planes UR - http://172.23.153.220/th.pdf ER -
