Application of silicon hybrid transfer trays to an indirect bonding system through bracket positions referred by 3D digital software

Recently many indirect bonding systems have been developed. However, the necessary laboratory work can be quite complicated. Therefore we developed a method of systematic positioning, and a simple and easy method using a silicone tray.We measured accurate bracket positioning height (BPH-line) and referred to Kalange's method using virtual setup models. We used two characteristically different chemical bonded silicon materials as the tray as part of our indirect bonding method.We found this system to be very useful, simple to apply, and accurate.
