Evaluating the Efficacy of the Sliding Mechanisms on Round-section Arch Wire
Syria38 participantsStarted 2023-07-07
Plain-language summary
Patients at the Orthodontic Department of the University of Damascus Dental School will be examined, and subjects who meet the inclusion criteria will be included. Then, initial diagnostic records (diagnostic gypsum models, internal and external oral photographs, and radiographic images) will be studied to ensure that the selection criteria are accurately matched.
This study aims to compare two groups of patients with mild to moderate skeletal Class II malocclusion (ANB angle between 5° and 7°), a normal to slightly increased vertical growth pattern (Björk's sum \> 390° and \< 406°), and an overjet of 5-10 mm. Experimental group: the patients in this group will be treated in the canine retraction phase with a sliding on a round-section archwire of 0.020 inch Control group: the patients in this group. Maxillary canine distalization was carried out using sliding mechanics on a 0.019 × 0.025-inch stainless steel archwire.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Adult patients aged 18-25 years
* Mild to moderate skeletal Class II malocclusion (ANB angle between 5° and 7°),
* A normal to slightly increased vertical growth pattern (Björk's sum \> 390° and \< 406°),
* An overjet of 5-10 mm.
* A further prerequisite was a camouflage treatment plan involving the extraction of the maxillary first premolars.
Exclusion Criteria:
* the presence of no systemic health issues or any systemic condition known to influence the rate of orthodontic tooth movement,
* active periodontal disease,
* absence of any permanent teeth in the upper arch (excluding third molars),
* crowding of 4 mm or greater,
* inadequate oral hygiene.
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
Change in the Rate of Maxillary Canine Retraction
Timeframe: T0: 10 minutes before starting canine retraction stage; T1: 30 days following the onset of canine retraction; T2: 60 days; T3: 90 days following canine retraction onset; TF: At completion of canine retraction (expected to occur within 3-5 months)
