An indirect bonding apparatus is made by initially placing spacer material
over a replica of the patient's tooth structure. A tray is then formed
over the spacer material and hardened. Next, the spacer material is
removed from the tooth replica and orthodontic appliances are placed on
the replica at desired locations. A matrix material is placed between the
tray and the replica and allowed to harden. Optionally, the apparatus
includes features for facilitating removal of the transfer apparatus
after the bonding procedure has been completed, and features for applying
firm, uniform pressure to the appliances during the bonding procedure.
Other aspects of indirect bonding are also described.
