Abstract

Objective: This paper introduces a method to make a transfer tray for indirect bracket bonding by using the Three-Dimensional (3D) software packages. Using the advanced technology of Computer-Aided Design (CAD) and Rapid Prototyping (RP) technology to reduce chair time and improve the bonding precision in orthodontics.

Method: The procedure included data acquisition of cast model and CBCT data. With the data, the tooth was segmented one by one, and the segmented data was saved as Stereolithography (STL) files. The tooth data and the cast data could be seen in a same 3D digital software and with the data the bracket position was decided by doctors. The transfer tray was designed in a reverse engineering software and printed by a 3D printing device.

Result: The method was used to make an individualized transfer tray in orthodontics.

Conclusion: With 3D scanning, CAD and RP technology, an efficient method of transfer tray production was established, which could meet clinical needs in indirect bonding of orthodontic and achieve a high efficiency and accuracy
