Molar Intrusion Using High Pull Headgear
Syria24 participantsStarted 2016-02
Plain-language summary
This prospective clinical study will evaluate the effect of high pull headgear for molar intrusion, compared with the control group, in adolescent patients with open bite malocclusion.
The study sample will consist of 24 patients with anterior open bite divided equally in two groups. The sample will be collected consecutively from patients attending the Orthodontic Department at Damascus university.
A modified version of the OBA (Open Bite Appliance),introduced by Erverdi and Usumez, will be applied for all patients. High pull headgears will be used in the first group, while, in the second (control) group, Open Bite Appliances will be used only.
The skeletal and dentoalveolar changes occurring after intrusion of posterior teeth will be assessed by using posteroanterior and lateral cephalometric radiographs; pre- and post- treatment changes for each group will be evaluated.

* patients between 12 and 18 years old with permanent dentition stage.
* Negative over bite of more than a mm
* Class I and Class II skeletal anteroposterior relationship.
Exclusion Criteria:
* Previous orthodontic treatment.
* Patients with syndromes, clefts, or craniofacial abnormalities.
* Class III skeletal anteroposterior relationship.
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.

Overbite
Timeframe: This variable will be evaluated twice; T0 before treatment, and T1 at the end of molar intrusion which will be abroximately after 7 months.
