Effects of Flapless Laser Corticotomy in Canine Retraction

Effects of Flapless Laser Corticotomy in Canine Retraction: A Randomized Controlled Trial

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

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
