Comparative 3-dimensional Superimposition Analysis of Dentition in Horizontal and Vertical Grower During the Retention Phase -A Prospective Clinical Trial''
India44 participantsStarted 2025-02-04
Plain-language summary
This study aims to investigate the relationship between facial type and relapse of dentition post-orthodontically during the retention phase. According to the retention theorem "teeth which have been moved through orthodontic treatment tend to naturally return to their original position. It is hypothesized that significant differences will exist in tooth movement patterns between horizontal and vertical growers, with horizontal growers exhibiting more pronounced tooth movement in the vertical plane particularly in the overbite as compared to the vertical growers . Furthermore, it is expected that facial type will influence the stability of orthodontic treatment outcomes, with long-faced individuals showing more relapse of mandibular incisor alignment and crowding. By exploring this relationship, this study aims to provide valuable insights into the factors influencing orthodontic treatment outcomes and stability. With long-faced individuals exhibiting more mandibular backward rotation and short-faced individuals showing forward rotation, which increases the risk of deep bite . Additionally, understanding these factors is crucial for orthodontists to predict and prevent potential relapse, ensuring optimal treatment results and long-term stability. Hence, the present trial will be undertaken to assess the changes and compare If there is any difference in tooth movement in 3-Dimensional superimposition in the dentition in horizontal and vertical growers post orthodontically over a period of retention phase.

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.
