Abstract: A method of making a transfer apparatus includes providing a physical mockup having a shape that corresponds to a positive shape of a patient's dental arch and a positive shape of one or more appliance analogs including ramps extending in a generally gingival direction from the analog. A transfer tray may be formed over the physical mockup, with the transfer tray representing a negative replica of at least a portion of the mockup. One or more receptacles and related channels are accordingly formed in the ray, each receptacle approximating a least a portion of the shape of an appliance analog and each channel approximating at least a portion of the shape of a ramp. An appliance associated with an appliance analog is placed into a receptacle of the one or more receptacles, and the appliance may be bonded to a tooth surface of the patient's dental arch.
