Evaluating the Influence of Showing Patients Their Predicted Teeth Alignment on Their Expectations and Satisfaction
Study Details
Study Description
Brief Summary
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.

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.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Three-dimensional digital simulation with fixed appliance The 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. |
Device: Fixed orthodontic appliances
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.
