About this study

The aim of the study is to compare the accuracy of orthodontic bracket and tube transfer between double layer silicone and double layer vacuum formed trays. The sample included 368 attachments bonded in 16 patients. Each patient received one silicone and one vacuum formed tray which were randomly allocated to provide 8 trays of each type for the upper and lower arches. 3D scan data and local best-fit alignments were used to calculate the translational and rotational movements of the orthodontic attachments. Chi-square and Mann-Whitney U tests were used to compare transfer accuracy and success between the groups.

Who can participate

Healthy volunteers accepted: No

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

Inclusion criteria

  • The presence of indication for both arches to be bonded in the same appointment

Exclusion criteria

  • Presence of restorations, hypoplasia or decalcification on vestibular tooth surfaces
  • Abnormal crown morphology

Treatment and study plan

Indirect bonding

Device

Indirect bonding is the technique where orthodontic appliances are first placed on a model of the patient and then transferred to the patient using some kinf of trays

Primary outcomes

  1. Transfer accuracy (composite outcome) in milimetres and degrees. Which is measured on computer software.

    Time frame: Day 0 - Day 2

    The positional deviations between the attachments on the models and the mouth
