- Primary Outcome Measures
Name Time Method Canine retraction rate. Timepoint: Before intervention, 4 months after intervention. Method of measurement: The distance between canine cusp tip and the line connection first rugae will be measured on occlusograms using a digital caliper. This amount will be divided to 4 to show canine retraction rate per month.
- Secondary Outcome Measures
Name Time Method Anchorage loss. Timepoint: before intervention and 4 months after intervention. Method of measurement: The distance between mesiobuccal cusp of first molar and the line connection first rugae will be measured on occlusograms using a digital caliper. This amount will be divided to 4 to show anchorage loss rate per month.
