Outcome Measures
Primary Outcomes (1)
Rate of canine retraction.
Rate of orthodontic tooth movement will be measured by calculating the difference in the canine position in mm throughout digital superimposition of consecutive digital models that will be made every four weeks.
5 months
Secondary Outcomes (1)
1. Assess bone level between intervention and control side.
bone level will be measured at the beginning of the study (T1) and by the fifth month of the study (T5)
Other Outcomes (1)
Assess Periodontal health at the injection side.
5 months
Study Arms (2)
injection site
EXPERIMENTALit is the arm where the patients will receive the PRF injection intraligamentally in distobuccal, and distopalatal areas of the distal surface of the canine also submucosal injection will be given buccally and palatially (0.25mm) for each side in either the right or left side of the arch.
control site
NO INTERVENTIONit is the arm where the patients will not receive any injection with the same method of retraction as the intervention side.
Interventions
Preparatory phase * Space closure will be done on a 17x25 stainless steel wire * Both molars will be indirectly anchored to the miniscrew * Extend closing coil spring of suitable length from the canine hock to the first molar hock for retraction. * Apply a force of 150gm for each side. The force is measured by a force gauge and activated each visit to keep it constant all over the retraction phase. PRF Injection protocol * The First injection will be 3 weeks before extraction * By the end of the fourth week the patients will be referred for pre-intervention records. Upper arch CBCT will be obtained to take preintervention measurements of the alveolar bone. * At the time of canine retraction patient will receive another injection immediately and an alginate impression will be taken * follow up every month and injection will be repeated month after month with an observational period of 5 months.
Eligibility Criteria
You may qualify if:
- adult patient
- Full set of permanent dentition (excluding third molars).
- Good oral hygiene
- protrusion cases that require extraction of premolars (Bimaxillary protrusion or class II div 1)
You may not qualify if:
- History of previous orthodontic treatment.
- Systemic disease or drugs affecting tooth movement.
- Smokers
- Poor oral health that precludes orthodontic treatment (presence of caries, active white spots, or periodontal diseases)
- Severe crowding cases with ectopic erupted canines
