Abstract
Improved methods for indirect bonding of orthodontic appliances, such as brackets, to the tooth surfaces of dental patients are provided. The methods use a transfer tray to accurately position the brackets on the tooth surfaces. Preferably, the tray is made of an ethylene vinyl acetate copolymer (EVA)/siloxane material. The brackets are coated with a protective coating to prevent them from becoming embedded in the tray. Preferably, a translucent, blue-tinted coating is used to cover the brackets. Dental restorative materials are used to bond the brackets to the teeth. The transfer tray is then removed from the mouth, while the appliances remain firmly bonded to the tooth surfaces.
