About this study

Official title: The Influence of Showing Patients the Three-dimensional Digital Simulation of Their Teeth Alignment Produced by Orthodontic Treatment With Fixed Appliance on Their Expectations and Satisfaction

Patients who have moderate crowding will be treated in this study. The efficacy of showing the predicted alignment of patient's teeth at the end of orthodontic treatment previously to treatment on their expectations from orthodontic treatment and their satisfaction with their teeth alignment will be assessed.

Read the detailed description

It is known that most patients expect that orthodontic treatment will improve their appearance which increases their confidence and self-esteem level.

The ability to approach patient's expectations to reality is crucial to making them reasonable and to improve patient's satisfaction with treatment outcomes.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Fixed orthodontic appliancesDevice

    Visual presentation of patient's predicted teeth alignment at the end of orthodontic treatment:

    Presenting predicted teeth alignment after orthodontic treatment to patients before treatment starts, by using photos and videos of dental digital set-up.

    Predicted teeth alignment can be described as: well-leveled and aligned patient's dental arches, well engaged posterior teeth and normal frontal teeth relationships.

Study groups in NCT05010616
Study groupRoleWhat they receive
Three-dimensional digital simulation with fixed applianceExperimentalThe records will be obtained at the first visit, which will be one week before placing brackets. At the second visit, the orthodontic appliances will be applied; then assessments will be taken after 15 minutes of showing the patient the digital simulation of their teeth alignment at the end of orthodontic treatment.

The record says: finished, as of the sponsor's last update on 14 Nov 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Syria. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

What does the primary outcome measure?

Change in patient's expectation towards teeth alignment: (time frame: T0: 1 week before placing brackets, T1: patient's second visit to clinician to begin the orthodontic treatment and after 15 minutes of showing patient the digital simulation of their teeth alignment at the end of orthodontic treatment). The study lists 13 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05010616, which also lists 6 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
