Eligibility Criteria
You may qualify if:
- Orthodontic patients needed extraction of upper first premolars, with age range from 18 - 25 years old.
- All patients were medically free. (See Appendix II)
- No previous orthodontic treatment.
- Adequate oral hygiene and periodontally healthy teeth.
- The canines were almost leveled and aligned.
- Maximum anchorage requirements.
- Healthy canines; no deep carious lesions, no endodontic lesions, no root canal treatment, nor internal or external root resorption.
- All patients were informed of the procedure and signed the consents.
You may not qualify if:
- Subjects were excluded from the study when:
- They failed to keep several consecutive appointments.
- Oral hygiene was subjectively judged as deteriorating during the preliminary stages of patient preparation.
- Compliance with the instructions provided was inadequate.
