Design outcomes

Primary

Measure	Time frame
1. Sagittal and vertical skeletal changes before and after treatment will be assessed using cone-beam computed tomography-generated cephalograms. 2. Dentoalveolar changes including: 2.1. Upper incisor angle changes. 2.2. The permanent maxillary first molar inclination changes. 2.3. Height and thickness of alveolar bone. Dentoalveolar changes before and after treatment will be assessed using cone-beam computed tomography.	—
