Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To prospectively compare axial inclination of the maxillary central incisor post-leveling and aligning and post-treatment with either distalisation using IZC screws or conventional retraction following four premolar extraction. Timepoint: T0 - 6 months (After leveling and aligning) T1 - 14 months (Post distalization and Post treatment) | — |
Secondary
| Measure | Time frame |
|---|---|
| To evaluate the changes in the soft tissue, including upper lip protrusion & nasolabial angle using cephalometric parameters post-leveling & aligning & after treatment using infra zygomatic screws & conventional retraction methods. Timepoint: T0 - 6 months (After leveling & aligning) T1 - 14 months (Post distalization & Post treatment) | — |
