Study Groups

Corticotomy
1. A full-thickness labial mucoperiosteal flap was reflected.
2. Two vertical corticotomies (1 mesial and 1 distal to the canine) were performed . The cortical bone was cut 2 to 3 mm below the alveolar crest towards the apex until bone marrow was exposed.
3. Cortical-cancellous bone grafts (0.5cc; PuraGraft, Kingwood, TX) were placed at the corticotomy sites.
4. The mini-screws were placed.
5. A nickel-titanium (NiTi) closed-coil spring was placed and secured with a 0.014"SS ligature wire at the canine and mini-screw. A Dontrix gauge (Orthopli Corp., Philadelphia, PA) was used to measure the force (150g).

Micro-Osteoperforation
1. MOPs were performed with a stainless-steel manual drill tip that had 1.6mm diameter with an adjustable depth set to 5mm (Excellerator® RT; Propel Orthodontics, Milpitas, CA).
2. Six perforations were made along 2 parallel vertical lines (each line with 3 holes spaced \~2mm apart) distal to the canine and perpendicular to the buccal cortical bone.
3. The mini-screws were placed.
4. A NiTi closed-coil spring was placed and secured with a 0.014"SS ligature wire at the canine and mini-screw. A Dontrix gauge was used to measure the force (150g).
