Evaluation of Maxillary Posterior Teeth Intrusion by Skeletally Anchored Mousetrap Appliance in Adult Patient With Anterior Open Bite.
Egypt20 participantsStarted 2024-08-25
Plain-language summary
Aim of the study: This clinical study aims to evaluate the dental, skeletal, and soft tissue effects of the Mousetrap appliance on the intrusion of maxillary posterior teeth in adult patients with anterior open bite.
Material and methods: An uncontrolled clinical trial will be conducted involving 20 participants aged 15 to 27 years with skeletal Class I, II, or mild Class III relationships and a measured AOB of 3-8 mm. Participants will receive mini-implants inserted in the anterior palate, with the Mousetrap appliance designed to promote molar intrusion while maintaining vertical dimension. Intraoral scans, radiographs, and clinical photographs will be recorded at baseline and post-intrusion.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Age ranging from 15 to 27 years.
* High angle patients with skeletal Class I, II or mild Class III.
* Patients with anterior open bite requiring maxillary posterior teeth intrusion as part of orthodontic treatment.
* Anterior open bite: range from 3-8 mm.
* Healthy adult patients.
* No previous orthodontic treatment.
* No evidence of either periodontal problems, gingival problems, or bruxism, at the beginning of orthodontic treatment.
* No medical problems interfering with orthodontic treatment.
Exclusion Criteria:
* Moderate to severe Class III skeletal relationship patients were excluded, as the molars intrusion would lead to increase the severity of Class III malocclusion.
* Patient with bad oral hygiene.
* Periodontal problems.
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?

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?
