Efficacy and Periodontal Parameters in Self-ligating Brackets Alone or With Corticotomy vs Conventional Brackets
Syria57 participantsStarted 2018-08-08
Plain-language summary
Patients who have severe crowding on the upper jaw that requires two first premolars extraction will be enrolled in this trial. The different types of brackets, such as self-ligating brackets and conventional brackets, and the various acceleration methods, such as corticotomy, have different effects on the orthodontic treatment time and the periodontal tissues. So, this study will assess and compare the overall leveling and aligning time and the changes in periodontal indices between patients with severe crowding, treating with self-ligating brackets associated with flapless corticotomy versus conventional brackets alone versus self-ligating brackets alone.
There are three groups:
The first group (control group): the patients in this group will be treated using conventional brackets alone.
The second group (Experimental group): the patients in this group will be treated using self-ligating brackets alone.
The third group (Experimental group): the patients in this group will be treated using self-ligating brackets associated with flapless corticotomy.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Sever crowding greater than 6 mm on the upper jaw in which orthodontic treatment requires extraction of two upper premolars.
* The Little's Index of Irregularity is more than 7 mm.
* Good oral health (plaque Index is less or equal to 1).
* Class I or class II (ANB ≤ 5) or class III (ANB ≥ 0).
* Overbite is between 0-4 mm.
* No skeletal constriction on the upper jaw.
* No congenitally missing or extracted teeth (except for the third molars).
Exclusion Criteria:
* Any systemic diseases affect teeth movement.
* Any congenital syndromes or cleft lip and palate.
* Bad oral health.
* The patient is not committed to periodic follow-up times.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Duration of teeth alignment
Timeframe: This will be measured immediately at the end of the alignment stage; this is expected to be within 180 to 200 days
