Indirect bonding trays for orthodontic treatment are made from a model of
the patient's dental arch that is manufactured using digital data and
rapid prototyping processes. The model includes one or more guides for
orienting an orthodontic appliance in a desired position on a model tooth
of the dental arch model. A holder is connected to the archwire slot of
the appliance and is brought into contact with the guide in order to move
the appliance to its intended position for subsequent manufacture of the
indirect bonding tray.
