Comparison Between Two Rates of Activation of Miniscrew-Supported Upper Jaw Expander in Adolescents

Egypt30 participantsStarted 2019-03-01

Plain-language summary

Miniscrew-supported maxillary expanders provide advantages over conventional tooth-supported expanders. However, there is no consensus in the literature regarding their activation protocol. The purpose of the clinical trial is to evaluate and compare the effects of slow and rapid activation rates of miniscrew-supported expanders on the skeletal changes, dento-alveolar changes and the pain experience.

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

Inclusion Criteria: * Permanent dentition. * Participants indicated for skeletal maxillary expansion due to unilateral or bilateral posterior cross bite or maxillary transverse deficiency * Good oral hygiene Exclusion Criteria: * History of previous orthodontic or orthopedic treatment * History of maxillary trauma * Patients with congenital craniofacial malformations * Patients receiving pharmacological agents or having systemic diseases that might affect the bone metabolism or the pain response

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

Timeframe: At baseline and an average of 5 months after the initial activation

Dento-alveolar inclination changes from baseline to an average of 5 months after the initial activation, measured using CBCT

Timeframe: At baseline and an average of 5 months after the initial activation
