“…Yellow circles indicate amounts of gable bends generated by the pliers. Japan), we aligned and leveled with a broad arch form (Ormco, Glendora, Calif) and referred to the studies of Andrews, 23 Germane et al, 24 and Park and Yang 25 for inclinations and angulations. We did not add a curve of Spee or a curve of Wilson (Fig 2, A).…”

“…The use of preadjusted appliance systems is based on the concept that ideal bracket placement will allow correction of tooth positions in all three planes of space with the placement of straight archwires. [1][2][3][4] For this reason, accurate bracket positioning is of critical importance in realizing the full potential of preadjusted edgewise appliances.…”

Objective: To elicit the magnitude, directional bias, and frequency of bracket positioning errors caused by the transfer of brackets from a dental cast to the patient's dentition in a clinical setting. Materials and Methods: A total of 136 brackets were evaluated. The brackets were placed on dental casts and scanned using cone beam computed tomography (CBCT) to capture 3-D positioning data. The brackets were then transferred to the patient's dentition with an indirect bonding method using vinyl polysiloxane (VPS) trays and later scanned using CBCT to capture the final bracket positioning on the teeth. Virtual models were constructed from the two sets of scan data and digitally superimposed utilizing best-fit, surface-based registration. Individual bracket positioning differences were quantified using customized software. One-tailed t tests were used to determine whether bracket positioning was within limits of 0.5 mm in the mesiodistal, buccolingual, and vertical dimensions, and 2u for torque, tip, and rotation. Results: Individual bracket positioning differences were not statistically significant, indicating, in general, final bracket positions within the selected limits. Transfer accuracy was lowest for torque (80.15%) and highest for mesiodistal and buccolingual bracket placement (both 98.53%). There was a modest directional bias toward the buccal and gingival. Conclusion: Indirect bonding using VPS trays transfers the planned bracket position from the dental cast to the patient's dentition with generally high positional accuracy.

“…1,2 Although the indirect bonding (IDB) method enables precise placement of the brackets on the tooth surface, thereby reducing the chair time, [3][4][5][6][7][8][9] it has a few disadvantages-cumbersome manual procedure, high cost, technique-and material-sensitivity, and significant learning curve. 8,10,11 Keim et al 10 and Sheridan 8 reported that 10% to 12% of the orthodontists in the United States have used the IDB method.…”

The purpose of this article is to introduce a new virtual orthodontic treatment (VOT) system, which can be used to construct three-dimensional (3D) virtual models, establish a 3D virtual setup, enable the placement of the virtual brackets at the predetermined position, and fabricate the transfer jig with a customized bracket base for indirect bonding (IDB) using the stereolithographic technique. A 26-year-old woman presented with anterior openbite, crowding in the upper and lower arches, and narrow and tapered upper arch, despite having an acceptable profile and balanced facial proportion. The treatment plan was rapid palatal expansion (RPE) without extraction. After 10 days of RPE, sufficient space was obtained for decrowding. After a 10-week retention period, accurate pretreatment plaster models were obtained using silicone rubber impression. IDB was performed according to the protocol of the VOT system. Crowding of the upper and lower arches was effectively resolved, and anterior openbite was corrected to normal overbite. Superimposition of the 3D virtual setup models (3D-VSM) and post-treatment 3D virtual models showed that the latter deviated only slightly from the former. Thus, the use of the VOT system helped obtain an acceptable outcome in this case of mild crowding treated without extraction. More cases should be treated using this system, and the pre-and post-treatment virtual models should be compared to obtain feedback regarding the procedure; this will support doctors and dental laboratory technicians during the learning curve.
