NCT07836816
Comparison of Maxillary Canine Retraction Rate With and Without Power Arm
The goal of this split-mouth randomized clinical trial is to compare maxillary canine retraction with and without power arm during fixed orthodontic treatment.The main question it aims to answer is What are the differences in the rate of maxillary canine retraction between the power- arm technique and the direct sliding technique over a 6-month period time?

Gingival Cleft Development at Two Time Points of Canine Retraction
The goal of this split-mouth randomized controlled trial is to assess whether the timing of extraction space closure-early vs. delayed initiation-affects the incidence of gingival cleft development in orthodontic patients. The main question it aims to answer is: Does the incidence of gingival cleft development get influenced by the specific time point at which orthodontic space closure is initiated following extraction? Quadrants will be assigned to the early movement group and the other to the delayed movement group and extractions will be performed accordingly. These will be assessed for the effect on development of gingival cleft development.
