Time Used for Orthodontic Surgical Treatment of Dentofacial Deformities in White Patients

PurposeThe aim of the present study was to assess the duration of each treatment phase that a patient with dentofacial disorders and eligible for orthodontic surgery undergoes and to identify those factors that determine the time. We have also included a description of the demographic and skeletal characteristics of the patients treated at our center, the surgery type, and movements performed.Patients and MethodsA sample of 148 patients undergoing orthognathic surgery from 2004 to 2007 at Princesa University Hospital, Madrid, was studied. The demographic data of each patient, their facial pattern, skeletal disorders, and surgical movements performed were recorded, as was the duration of orthodontic treatment, both pre- and postoperatively, length of surgery, and length of hospital stay.ResultsThe length of preoperative orthodontic treatment was 24 months and that of postoperative treatment was 12 months. The average operative time was 4 hours for those interventions in which both dental arches were involved, and the average length of hospital stay was 3 days. No relevant differences were found for the length of orthodontic treatment according to gender, age, or type of skeletal disorder. Differences were observed in the length of hospital stay between those patients who underwent segmentation of the maxilla and those who did not.ConclusionsThe length of the different phases into which an orthodontic surgical treatment is divided can differ within some given limits. However, it does not depend on either the patients' demographic skeletal characteristics or the surgical movements performed.
