Apparatus for use in indirect bonding of orthodontic appliances includes a container having a chamber and a placement device received in the chamber. At least one orthodontic appliance is releasably connected to the placement device and has a base with a contour that is a replica of a portion of the patient's tooth structure. A bonding composition for bonding the appliance to the patient's tooth structure is applied to the base before the container is closed by the manufacturer, such that the practitioner can simply remove the placement device from the chamber and immediately transfer the appliances to the patient's teeth.

The invention claimed is: 1. Apparatus for use in indirect bonding of orthodontic appliances comprising: a container having a chamber, said container including a barrier layer to reduce the passage of volatile components therethrough; an orthodontic placement device received in the chamber, wherein the placement device comprises a tray and has a construction matching at least a portion of the patient's dental arch; a plurality of orthodontic appliances releasably connected to the placement device, each appliance having a base with a contour that is a replica of a contour of a portion of the patient's tooth structure; and a bonding composition on the base of each appliance for bonding to the patient's tooth structure. 2. The apparatus of claim 1 wherein the tray comprises a shell and a matrix material received in the shell, wherein the matrix material has a Shore A hardness that is less than the Shore A hardness of the shell. 3. The apparatus of claim 1 wherein the placement device extends across all of the teeth of a dental arch. 4. The apparatus of claim 1 wherein the placement device extends across the teeth of a quadrant of a dental arch. 5. The apparatus of claim 1 wherein the base is made of a curable composition. 6. The apparatus of 5 wherein the curable composition is a light-curable composition. 7. The apparatus of claim 1 wherein the container is made of a material that substantially blocks the passage of actinic radiation. 8. The apparatus of claim 1 wherein the container includes structure for substantially hindering shifting of the placement device in the chamber. 9. The apparatus of claim 1 wherein the chamber has a configuration substantially matching the configuration of the placement device. 10. The apparatus of claim 1 wherein the bonding composition comprises a light-curable composition. 11. The apparatus of claim 1 wherein the bonding composition comprises a chemical curing composition. 12. The apparatus of claim 1 wherein the bonding composition comprises one component of a two-component adhesive. 13. The apparatus of claim 1 wherein the container also includes an additional quantity of at least one volatile component of the bonding composition in a location other than in the bonding composition that is applied to the base of each appliance. 14. A method of making apparatus for orthodontic indirect bonding comprising: providing a plurality of orthodontic appliances; obtaining information in an orthodontic practitioner's office relating to the contour of at least a portion of the patient's tooth structure; providing the information to a manufacturer of indirect bonding trays; forming a base at the manufacturer's facility on each appliance to replicate a portion of the patient's tooth structure; connecting each appliance to a placement device, wherein the placement device comprises an indirect bonding tray; applying at the manufacturer's facility a quantity of bonding composition to each base; placing the placement device within a container; and sending the container to an orthodontic practitioner after the placement device is placed within the container. 15. The method of claim 14 wherein the act of determining the contour of at least a portion of the patient's tooth structure is carried out using digital data. 16. A method of making apparatus for orthodontic indirect bonding according to claim 14 wherein the act of determining the contour of at least a portion of the patient's tooth structure is carried out by taking an impression of the patient's tooth structure. 17. A method of making apparatus for orthodontic indirect bonding according to claim 16 and including the act of making a physical replica using the impression. 18. A method of making apparatus for orthodontic indirect bonding according to claim 14 wherein the base is made of a curable composition. 19. A method of making apparatus for orthodontic indirect bonding according to claim 14 wherein the act of placing the placement device within a container includes the act of placing the placement device in a chamber of the container that is protected from actinic radiation.
