The Use of 2D and 3D Imaging Modalities and Its Influence on Diagnosis and Treatment Planning in Orthodontics

Belgium32 participantsStarted 2012-01

Plain-language summary

Research questions: 1. Will the panoramic images derived from cone beam CT data give better diagnostic ability than conventional panoramic radiographs? 2. Will 3D cephalometric analysis offer the orthodontists and surgeons better information for treatment planning? 3. Will the 3D cephalometric analysis give more accurate treatment plan and better treatment outcome? General hypothesis and special aims Overall aims: * To compare 2D versus 3D cephalometric analysis: treatment planning and therapeutic outcome. * To determine the accuracy and diagnostic ability and usability of the 3D cephalometric analysis. * To evaluate the diagnostic ability and usability of the panoramic image derived from cone beam CT data as compared to 2D panoramic images. * To evaluate the value of the cone beam CT data in cephalometric analysing process for orthodontic and maxillofacial surgery treatment. Hypotheses: 1. The availability of the 3D cephalometric analysis influences the orthodontic and maxillofacial treatment plan and decision, and might change the treatment outcome. 2. Panoramic images derived from cone beam CT data may provide equal information for diagnosis as conventional panoramic images. 3. Cone beam CT will be able to replace "classic orthodontic imaging" being more time and dose efficient and having a beneficial effect on treatment outcome.

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.
