|---|---|---|
| Rate of canine retraction | The digital models will be superimposed using 3rd ruguae area. For each model, the distal point of the canine will be marked and the distance between 2 points will be calculated. The amount of canine retraction per month will be calculated from the difference in the canine cusp position in the four models. The digital models will be superimposed using 3rd ruguae area.
