Syria22 participantsStarted 2017-05-01

Plain-language summary

This experimental study aims to evaluate the efficiency of the orthodontic removable traction appliance in the treatment of skeletal class III malocclusion. The study sample will consist of 44 patients with skeletal class III malocclusion. The sample will be allocated randomly into two groups: experimental group and control group. The dentoskeletal changes will be assessed by using lateral cephalometric radiographs before treatment and after obtaining 3mm positive overjet.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Patients in early mixed dentation (8-10 years old). * Skeletal class III caused by maxillary deficiency with or without mandibular prognathism judged clinically and confirmed radiographically(ANB≤1). * Anterior crossbite on two teeth or more or an edge-to-edge bite. * Normal inclination of the lower incisors with the mandibular plane. Exclusion Criteria: * Poor oral hygiene. * Previous orthodontic treatment. * Patients with syndromes, clefts, or craniofacial abnormalities. * Severe skeletal class III primarily resulting from mandibular prognathism (ANB less than - 4) * Patients with facial asymmetry. * Patients with vertical growth pattern.

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

The change of the ANB angle

Timeframe: Assessment will be done before treatment (T0) and after obtaining 3-mm positive overjet which will be approximately obtained after 6 months (T1).
