| Measure | Time frame |
|---|---|
| Me- y axis: It is the distance between Menthon and Y-Axis on cephalogram. Timepoint: It is evaluated in three time periods: before intervention (T0), one week after intervention (T1) and one year after intervention (T2). Method of measurement: it would be evaluated by standard metallic ruler based on distance between cephalometric reference points on lateral cephalograms.;B-Y axis: It is the distance between B point and Y-Axis on cephalogram. Timepoint: It is evaluated in three time periods: before intervention (T0), one week after intervention (T1) and one year after intervention (T2). Method of measurement: it would be evaluated by standard metallic ruler based on distance between cephalometric reference points on lateral cephalograms.;Pog -Y axis: It is the distance between Pog and Y-Axis on cephalom. Timepoint: It is evaluated in three time periods: before intervention (T0), one week after intervention (T1) and one year after intervention (T2). Method of measurement: it would be evaluated by standard metallic ruler based on distance between cephalometric reference points on lateral cephalograms.;Me- X axis: It is the distance between Menthon and X-Axis on cephalogram. Timepoint: It is evaluated in three time periods: before intervention (T0), one week after intervention (T1) and one year after intervention (T2). Method of measurement: it would be evaluated by standard metallic ruler based on distance between cephalometric reference points on lateral cephalograms.;B-X axis: It is the distance between B point and X-Axis on cephalogram.
