Abstract: In a preferred embodiment of the disclosure, tooth attachment placement (TAP) device or for assisting a user in placing one or more appliances or attachments on one or more teeth is disclosed. The TAP device comprises single tooth jigs connected through splines. The geometry of the device is automatically designed in the treatment planning unified workstation, thereby generating a digital STL file. Then the device is created from a non-flexible biocompatible material by a 3D printer in accordance with the digital STL file. Appliance, for example, may be a bracket or a bracket shim; and the attachment may be an aligner attachment or a pad. Different embodiments of the TAP device are disclosed. Methods for verifying the accuracy of the placements of the brackets on the teeth using the TAP device are disclosed.
