入选标准
- •Full complement of teeth with no congenitally missing teeth except 3rd molars.
- •Minor or no crowding cases requires four premolars extraction, canine retraction & maximum anchorage with bimaxillary dentoalveolar protrusion.
- •No history of previous orthodontic treatment
- •Clinically healthy patients with no history of drug intake and\or no history for any systemic illness, syndromes, craniofacial deformities.
- •Vital teeth with normal periodontium and no root resorption.
- •Adequate oral hygiene; probing depth values not exceeding 3 mm across the entire dentition; adequate thickness of the attached gingiva (1-2 mm).
- •No radiographic evidence of bone loss.
排除标准
- •Systemic disease that might have affected bone formation or density, such as osteoporosis, hyperparathyroidism, or vitamin D deficiency.
- •Presence of any local or systemic surgical contraindication.
- •Extracted or missing permanent tooth/teeth except for 3rd molars.
- •Facial asymmetry
研究组 & 干预措施
Maxillary flapless laser corticotomy group
Flapless laser corticotomy will randomly be assigned to one side of the 14 maxillary arches (experimental side) before canine retraction.

结局指标
主要结局
Rate of canine retraction.
时间窗: 3 months of canine retraction , distance (mm) moved by the canine distally per month
distal movement of the canine , measurement unit mm divided by time unit month , using scanned digital models
次要结局
- First molar anchorage loss(3 months, assessed immediately before canine retraction and at the end of 3 months of canine retraction)
- Periodontal condition(3 months , immediately before canine retraction , and at the end of 3 months of canine retraction)
- Pulp vitality(3 months, assessed immediately before canine retraction , and at the end of 3 months of canine retraction)
- Canine rotation(3 months, assessed at the beginning of treatment (base line ), and at the end of 3 months of canine retraction)
- Root resorption(3 months , assessed at the beginning of treatment (base line ), and at the end of 3 months of canine retraction)
