简要总结
This study was designed to enroll a series of 10 consecutive patients who met the inclusion criteria. Patients were treated in the Department of Orthodontics and Dento-Facial Orthodopedics of the University of Liège. Two senior's orthodontists and two senior's periodontists were involved in the orthodontic treatment and in the surgical procedures respectively. All clinical, radiographic and periodontal measurements and all orthodontic parameters were performed at baseline and after the orthodontic treatments. Tree examiners collected the overall data.

结局指标
主要结局
Radiographic change from Baseline and after 1year
时间窗: Baseline and after 1year
The patients underwent baseline and post treatment CBCT scans (Somaton® Emotion; Siemens, Munich, Germany). Measurements of the alveolar bone changes in the lower front region on pre- and post- treatment CT volumes were done by reformatting the orthogonal slices, along the sagittal, coronal and axial length axes of each individual tooth. A strict vestibular bone level measurement (sagittal slice) and three alveolar bone width measurements at crestal level, 3mm from the crest and 6mm from the crest (axial slices) were performed per individual tooth. In addition, CT images were analyzed in using a dedicated platform in an image processing software (MeVisLab, MeVis Medical Solutions AG, Bremen,Germany) where pre- and post-treatment volumes were superposed using rigid image registration. Semi-automatically segmentation using region growing with same seed-point and threshold value for both scans, was followed with a hole-filling algorithm to obtain segmented volumes of the cropped image in
