Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 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: 1. Mesial/distal teeth movement (distance change in millimeters) 2. Extrusion/ intrusion teeth movement (distance change in millimeters) 3. Rotation / tip/ torque (angulation change in degree) 4. Canine teeth retraction 5. Incisor teeth retraction | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Pain level will be measured using visual analogue scale (VAS) at baseline, day 1, day 3 and day 7 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. 3. Root resorption will be evaluated using periapical radiograph at completion of treatment | — |
