Accepts healthy volunteers: no
Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: The 14 patients maxillary and mandibular arches will be allocated into a split-mouth design, so the sample will be set up each patient to act as his/her own control
Primary purpose: TREATMENT

Brief summary: This study is conducted to evaluate the effects of flapless laser corticotomy on the rate of canine retraction.


Eligibility criteria: Inclusion Criteria:

* 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.

Exclusion Criteria:

* 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
