Purpose: The study purpose was to assess whether mandibular setback surgery by intraoral vertical ramus osteotomy (IVRO) induces obstructive apnea and hypopnea in healthy Class III patients without a history of respiratory dysfunction. We hypothesized that the apnea-hypopnea index (AHI) would not exceed 5 events per hour after surgery.

Patients And Methods: A prospective cohort study was conducted.

Purpose: A retrospective evaluation was performed of dentoalveolar and skeletal stability 1 year after mandibular setback surgery using intraoral vertical subcondylar osteotomy (IVSO) combined with intermaxillary fixation.

Patients And Methods: Twenty-eight patients (16 men, 12 women) with skeletal Angle Class III malocclusions were included. Mean age at start of treatment was 23.

Introduction: The aims of this study were to determine reasons for orthodontic-surgical treatment, to quantify the perceptions of possible improvement 10 to 14 years after treatment, and to assess factors that affect treatment satisfaction and socio-dental impacts on quality of life.

Methods: The participation rate was 36 of 78 patients; their mean age was 45.7 years (SD, 10.

Purpose: To evaluate the short- and long-term stability of mandibular advancement surgery with sagittal split osteotomy (SSO), and to investigate when relapse occurs and identify variables contributing to relapse.

Patients And Methods: Thirty-six patients with Class II anomalies were included; the mean age at surgery was 33.0 years.

The purpose of the study was to investigate root lengthening during orthodontic treatment in relation to the age of the patient, the developmental stage of the root, and the anticipated growth. Specifically, the potential benefit of treating young teeth was addressed. The sample consisted of 80 patients with Angle Class II division 1 malocclusions, treated with extraction of at least two maxillary first premolars, and edgewise technique with 0.
