Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To evaluate the external apical root resorption in the maxillary anterior teeth using cone beam computed tomography taken pre (T0) and at the end of the space closure (T1) with modified intrusion and retraction mechanics.Timepoint: Pre Retraction (T0)(Before space closure - 0 months ) Post Retraction (T1)( After space closure- 12 months) | — |
Secondary
| Measure | Time frame |
|---|---|
| To evaluate change in buccal & palatal crestal bone height after completion of retraction. To evaluate change in buccal & palatal alveolar bone thickness of the maxillary anterior teeth after completion of retraction.Timepoint: Pre Retraction (T0)(Before space closure -0 months) Post Retraction (T1)(After space closure- 12 months). | — |
