About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Class I malocclusion with moderate crowding (between 4-6 mm of tooth-size-arch-length-discrepancy).
  • Good oral hygiene and periodontal health.
  • No severe skeletal discrepancy.
  • Normal proclination for the upper and lower incisors.

Exclusion criteria

  • Bimaxillary dentoalveolar severe protrusion.
  • Need for extraction.
  • Previous orthodontic treatment.
  • Subject with psychological abnormalities.
  • congenitally missing or extracted teeth (except for the third molars).

Treatment and study plan

Fixed orthodontic appliances

Device

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.

Primary outcomes

    Patients will be asked: Do you expect the orthodontic treatment to improve your chance of a good career? Question will be answered on paper using the Visual Analogue Scale (VAS) with grades from 0 to 10.

    Grade 0 = not expected. Grades 1-3 = less expected. Grades 4-6 = average expected. Grades 7-9 = highly expected. Grade 10 = most expected.

  7. Change in patient's expectations towards getting a better social confidence

    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
