• Status: Completed
• Enrollment: 14
• Est. completion date: December 30, 2020
• Est. primary completion date: December 1, 2020
• Accepts healthy volunteers: No
• Gender: All
• Age group: 18 Years and older

Eligibility

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

Related Conditions & MeSH terms

• Bimaxillary Protrusion
• Dental Malocclusion
• Malocclusion

Intervention

Other:
• Flapless laser corticotomy
The flapless laser corticotomy will be done by Er, Cr: YSGG laser as a series of circular holes will be made along with the planned position. The depth of laser cutting will be measured and controlled continuously during the operation by the periodontal probe with stopper read to each 3mm depth in addition to a few parts of a millimetre depth into the medullary bone to enhance bleeding. Canine retraction will be started after this procedure.
• Canine retraction
canine retraction will be done on 17x25 stst archwire using coil spring adjusted to 150 gm, and miniscrews will be used as an indirect method of anchorage reinforcement

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Rate of canine retraction.	distal movement of the canine , measurement unit mm divided by time unit month , using scanned digital models	3 months of canine retraction , distance (mm) moved by the canine distally per month
Secondary	Canine rotation	rotation of canine measured in degrees , after 3 months of canine retraction using scanned digital models	3 months, assessed at the beginning of treatment (base line ), and at the end of 3 months of canine retraction
Secondary	First molar anchorage loss	mesial movement of first molar measured in mm , after 3 months of canine retraction using scanned digital models	3 months, assessed immediately before canine retraction and at the end of 3 months of canine retraction
Secondary	Root resorption	canine root length measured in mm using cone beam CT scans	3 months , assessed at the beginning of treatment (base line ), and at the end of 3 months of canine retraction
Secondary	Periodontal condition	assessed using periodontal probe to measure : probing depth in mm	3 months , immediately before canine retraction , and at the end of 3 months of canine retraction
Secondary	Pulp vitality	assessed using thermal (Cold ) test , by application of dry cotton sprayed with ethyl chloride	3 months, assessed immediately before canine retraction , and at the end of 3 months of canine retraction
