Influence of Four Orthodontic Bracket Prescriptions in Arch Width and Torque

76 participantsStarted 2015-05-01

Plain-language summary

The study compares torque and arch width changes between four different orthodontic bracket prescriptions and determine whether changes in dental torque are correlated to changes in arch width at the end of orthodontic treatment. From an initial sample of 250 patients who sought treatment at the Department of Orthodontics (University of Valencia, Spain), a subsample of 76 patients (31 men and 45 women) were selected to meet inclusion criteria. The sample was randomly allocated into four groups according to four different orthodontic bracket prescriptions: Prescription A (n=22): Mini-Taurus® (Rocky Mountain©); Prescription B (n=17): Smart Clip® SL3 High Torque (3M Unitek©); Prescription C (n=18): Tip-Edge Plus® (TP Orthodontics©); Prescription D (n=19): Victory® (3M Unitek©). Initial (T0) and final (T1) plaster and digital study models were available for all patients. Measurements were taken from frontal and occlusal images of the models by a single experienced operator.

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.

Change of posterior torque from the initial occlusion to the final occlusion at the end of the orthodontic treatment.
