This comparative controlled clinical study aims to evaluate and compare the effectiveness of piezocision and low-level laser therapy (LLLT) as adjunctive interventions to accelerate orthodontic canine retraction. Participants will be randomly assigned to one of three groups: piezocision, LLLT, or a control group (no adjunctive procedure). The study will assess the impact of these interventions on the rate of tooth movement, the type of tooth movement, and patient experience.

On both right and left sides, LLLT will be performed at the beginning of canine retraction, after 3, 7, 14 days, and then every 14 days for a total four-month period.
On both right and left sides, a minimally invasive flapless piezocision procedure will be performed each month from the beginning of the canine retraction for a total four-month period.

Rate of canine retraction
The rate of distal movement of the maxillary canine measured in millimeters per month (mm/month).
Time frame: Four months from the beginning of maxillary canine retraction.
Maxillary canine rotation and tipping.
Measured in degrees
Time frame: Four months from the beginning of maxillary canine retraction.
Maxillary first molar mesial movement
Maxillary first molar mesial movement (measured in mm)
Time frame: Four months from the beginning of maxillary canine retraction.
Maxillary first molar rotatiob
(measured in degrees).
Time frame: Four months from the beginning of maxillary canine retraction.
Patient-Reported Pain Intensity
Pain intensity will be measured using a 10-centimeter Visual Analogue Scale (VAS). The scale ranges from 0 to 10, where 0 represents "no pain" and 10 represents "the worst possible pain" . Therefore, higher scores indicate a worse outcome (greater pain intensity).
Time frame: Four months from the beginning of maxillary canine retraction.
