Sixty patients requiring extraction-based treatment of the maxillary first premolars, followed by retraction of the maxillary canines, will be randomly assigned to three groups: piezocision, low-level laser therapy, and control. In each group, canine retraction will be initiated after completion of the leveling and alignment phase, using closed nickel-titanium coil springs that apply 150 g of force per side. For anchorage, a soldered transpalatal arch will be used. Pre- and post-distalization dental casts will be assessed to evaluate the rate of canine retraction, canine rotation, and anchorage loss over the follow-up period until a Class I canine relationship is achieved. Periodontal health will be assessed before and after canine retraction by evaluating the following parameters: plaque index, gingival index, bleeding index, and probing depth.

Duration of upper canine retraction
Timeframe: The months required to complete the retraction procedure will be recorded. Completion of this procedure is expected to occur within four months in the experimental groups and seven months in the control group
Rate of retraction
Timeframe: Time Frame: The calculation of the rate of retraction will be done once the retraction procedures have finished. Completion of this procedure is expected to occur within 4 months in the experimental groups and 7 months in the control group.
