Alveolar bone thickness
Alveolar bone thickness will be assessed in vestibular and oral sides, parallel to the cervical reference line (CRL) at 3 different evels and expressed in millimeters.
Time frame: From date of randomization until the date of first documented acceptable teeth alignment, assessed up to 12 months.
Alveolar bone height
Alveolar bone height loss will be measured perpendicularly to the CRL in both vestibular and oral sides. It will be represented as the difference between pretreatment and post treatment distance from alveolar crest to the CRL, expressed in millimeters.
Time frame: From date of randomization until the date of first documented acceptable teeth alignment, assessed up to 12 months.
Comparison of transverse dental changes between the two groups.
Assessment of inter-molar and inter-canine widths
Time frame: From date of randomization until the date of first documented acceptable teeth alignment, assessed up to 12 months.
Assessment of Apical root resorption
comparison of root length changes after treatment
Time frame: From date of randomization until the date of first documented acceptable teeth alignment, assessed up to 12 months.
