Distalization With Aligners: Anchorage Options
Turkey (Türkiye)22 participantsStarted 2021-12-30
Plain-language summary
Background: To compare the dentoskeletal effects of Class II elastic anchorage and infrazygomatic crest (IZC) miniscrew anchorage in sequential maxillary molar distalization using clear aligners.
Methods: A total of 22 patients with Angle Class II malocclusion treated with clear aligners and maxillary molar distalization were included. Based on the anchorage method patients were divided into two groups: Class II elastics (Group 1) or IZC miniscrews (Group 2). Lateral cephalometric radiographs and digital models were obtained from all patients before treatment (T0) and after distalization of the second premolars (T1) to assess skeletal and dental changes. Geomagic Control X was used to superimpose the digital models.

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
1
Evaluation of the Dentoskeletal Effects of Maxillary Molar Distalization with Clear Aligners: Class II Elastic Anchorage vs. Miniscrew Anchorage
Timeframe: Patients were collected and treatmets were started up to 9 months. At 12 weeks, miniscrews were inserted in group 2 and elastics were started to be used in each group. Final data were collected up to 20 months.
