Who can participate

Healthy volunteers accepted: No

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

Inclusion criteria

  • Patients with permanent dentition starting orthodontic treatment requiring vestibular fixed orthodontic appliance according to treatment needs.
  • Fully erupted set of teeth (except for the second and third molars).
  • Mild to moderate crowding.
  • Good oral hygiene.

Exclusion criteria

  • Any medical or dental conditions that may impede orthodontic treatment.
  • Patients with severe crowded or rotated teeth, or partially erupted teeth that will hinder the proper positioning of the brackets or bonding trays.
  • Patients with any enamel abnormalities, hypoplastic enamel, white spot lesions.
  • Presence of large restorations or carious teeth.
  • Presence of supernumerary or impacted teeth or tooth agenesis.

Treatment and study plan

3D printed indirect bonding trays

Other

Intraoral scan of participants' upper dentition will be obtained. Digital stereolithography models will be used for virtual bracket positioning on software. The digital setup of the brackets will be used for designing the customized indirect bonding transferring tray for one quadrant of the upper arch of each patient.

3D printed guiding direct bonding trays

Other

Intraoral scan of participants' upper dentition will be obtained. Digital stereolithography models will be used for virtual bracket positioning on software. The digital setup of the brackets will be used for designing the customized guiding direct bonding tray for the other quadrant of the upper arch of each patient.

Primary outcomes

  1. Bracket Placement Accuracy

    Time frame: Immediately after bonding

    Measured as the linear and angular deviation between the virtually planned and actual bracket positions using 3D superimposition technique of the digital setup model and intraoral scan after bonding.

Secondary outcomes

  1. Immediate Bracket Failure

    Time frame: Immediately after bonding

    Immediate bracket failure will be assessed for each quadrant during the removal of the bonding trays at the bonding appointment.
