A new customized lingual indirect bonding system.

JCO/AUGUST 2000 M of the methods devised for lingual indirect bonding1,2 have been variations on the technique originally proposed by Hoffman,3 using a transfer tray fabricated on the working cast. Custom bracket positioning with these techniques requires transferring the brackets from the ideal setup back to the working cast, which makes the laboratory procedure more complex and expensive. More recently, several indirect bonding procedures have been developed in which individual transfer trays are fabricated on the ideal setup.4-6 Thus, the customized brackets are directly transferred from the ideal setup to the patient, and the model does not have to be duplicated several times. In 1996, we introduced a lingual indirect bonding method that used a wire-resin assembly as the transfer tray.4 We found, however, that the wire part of the transfer tray can be deformed during laboratory and clinical procedures. A new customized lingual indirect bonding system, presented in this article, avoids such deformation by
