- Primary Outcome Measures
Name Time Method <br> Tooth movement measured using 3D inspection software at pretreatment, at various set up stages which are: the 6th clear aligners, at 12th clear aligners and at completion:<br> 1. Mesial/distal teeth movement (distance change in millimeters)<br> 2. Extrusion/ intrusion teeth movement (distance change in millimeters)<br> 3. Rotation / tip/ torque (angulation change in degree)<br> 4. Canine teeth retraction<br> 5. Incisor teeth retraction<br>
- Secondary Outcome Measures
Name Time Method <br> 1. Pain level will be measured using visual analogue scale (VAS) at baseline, day 1, day 3 and day 7<br> 2. Teeth off track from clear aligners will be evaluated at pretreatment, at 12th clear aligners, at 24th clear aligners and at completion by observation.<br> 3. Root resorption will be evaluated using periapical radiograph at completion of treatment<br>
