Abstract:
A retrospective study of 20 patients treated for vertical maxillary excess between 2009 and 2010, solely by superior surgical repositioning of the maxilla. Clinical and radiological cephalometric parameters were analyzed statistically and their impact on achieving the predicted postoperative mandibular autorotation and on relapse. According to our study, patients presenting with an anterior open bite and a low occlusal plane angle might fail to achieve the predicted mandibular autorotation and are prone to postoperative relapse. No correlation was found between the extent of maxillary impaction and the presence of autorotation.
