• Good oral hygiene.

Exclusion Criteria

Primary Outcome Measures

Name	Time	Method
Alveolar bone thickness	From date of randomization until the date of first documented acceptable teeth alignment, assessed up to 12 months.	Alveolar bone thickness will be assessed in vestibular and oral sides, parallel to the cervical reference line (CRL) at both mid root and apex levels and expressed in millimeters.
Alveolar bone height	From date of randomization until the date of first documented acceptable teeth alignment, assessed up to 12 months.	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.

Secondary Outcome Measures

Name	Time	Method
Comparison of transverse dental changes (inter-molar and inter-canine widths) between the two groups.	From date of randomization until the date of first documented acceptable teeth alignment, assessed up to 12 months.	Assessment of inter-molar and inter-canine widths at crown, CEJ and mid-root levels.
