- Primary Outcome Measures
Name Time Method The rate of canine regression. Timepoint: The first month, the second month, the third month and the fourth month after laser corticotomy. Method of measurement: First, a three-dimensional scan is prepared from the study casts prepared each month. The reference lines in the scans include the midpalatal ridge and the Roga line. The Roga line is drawn from the midpoint of the third Roga on the right side of the palate perpendicular to the midline.
- Secondary Outcome Measures
Name Time Method Anchorage loss. Timepoint: Pain score. Method of measurement: vitality test.
