The Impact of a 3D Imaging Tool on Reducing Gum Recession During Orthodontic Treatment With Aligners
Belgium40 participantsStarted 2025-09-04
Plain-language summary
This study investigates whether using 3D imaging technology (Cone Beam Computed Tomography or CBCT) for orthodontic treatment planning with aligners can reduce the risk of gingival recession in adult patients seeking dental arch expansion. Many aligner treatments involve expanding the dental arches to address issues like crowding and "black corridors," but this can sometimes lead to gum recession.
The research compares two groups of patients: one group will have their treatment planned using CBCT, which allows for detailed 3D visualization of the teeth and bone structure, while the other group will follow a conventional 2D treatment plan. The goal is to see if the 3D tool helps prevent gum recession and other periodontal problems like bone thinning, as well as to assess the impact on other factors like upper airway dimensions.
The study is a randomized controlled trial with 40 participants. It will track changes in gum health, bone structure, and airway volume over the course of treatment. The researchers aim to find out if the advanced imaging tool provides significant benefits compared to traditional planning methods.

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?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
