Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Rate of root-position correction (°/month). Timepoint: At the beginning of the study (before the start of the intervention) and 4 months after intervention start. Method of measurement: By measuring the root angle relative to the palatal plane on sagittal CBCT slices. | — |
Secondary
| Measure | Time frame |
|---|---|
| Amount of root resorption (mm). Timepoint: At the beginning of the study (before the start of the intervention) and 4 months after intervention start. Method of measurement: By measuring the change in root length (resorption) on CBCT images. | — |
