Clinical Investigation of the Transfer Accuracy of Semi-Digital and Fully Digital Indirect Bonding Trays

This randomized clinical study compares the transfer accuracy of semi-digital and fully digital indirect bonding trays in orthodontic treatment. Thirty-two patients were randomly divided into two groups to receive brackets bonded with either semi-digital trays (thermoformed on 3D printed models) or fully digital trays (directly 3D printed). The primary outcome measures are linear and angular deviations between the virtually planned and actual clinical bracket positions, analyzed using 3D superimposition techniques.

Inclusion criteria

  • Patients aged 12-25 years in permanent dentition
  • Had a mild irregularity (≤ 3mm)
  • Requiring comprehensive fixed orthodontic treatment and had no previous orthodontic therapy
  • Not having malformed, excessively rotated, large restorations or missing teeth in the upper arch

Treatment and study plan

Semi-Digital Indirect Bonding

Procedure

Bonding brackets using thermoformed transfer trays.

Fully Digital Indirect Bonding

Procedure

Bonding brackets using 3D printed transfer trays.

Primary outcomes

  1. Linear Transfer Accuracy

    Time frame: Immediately after the bonding procedure (Day 1)

    Linear deviations between the virtually planned bracket positions and the actual clinical bracket positions. Measurements are calculated by superimposing the post-bonding intraoral scans onto the virtual setup models using GOM Inspect software.

    Unit of Measure: Millimeters

  2. Angular Transfer Accuracy

    Time frame: Immediately after the bonding procedure (Day 1)

    Angular deviations between the virtually planned bracket positions and the actual clinical bracket positions. Measurements are calculated by superimposing the post-bonding intraoral scans onto the virtual setup models using GOM Inspect software.

    Unit of Measure: Degrees
