Abstract:
The aim of this paper is to describe a simple and efficient system of indirect bonding that can be easily performed in the orthodontic office. The transfer tray is formed with transparent polyvinylsiloxane of medium viscosity that can be used in combination with light-cured adhesives. Low-friction ligatures are placed on each bracket to eliminate the undercuts under the bracket wings and to prevent penetration of silicone material into the bracket slots. This procedure has several advantages when compared with similar methods for indirect bonding: it allows easier tray removal, it lowers the risk of bracket debonding during the tray removal, and it reduces ligation time with low-friction ligatures.
