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.

First claim

We claim:

1. A tooth attachment placement device comprising:
a geometry derived from an inverse shape of a virtual model of a dentition of a patient having virtual orthodontic brackets placed thereon, the geometry having an upper spline and a lower spline with a plurality of fixed single tooth jigs interconnected therebetween such that the upper spline and the lower spline extend along a portion of the geometry of the tooth attachment placement device to define a complimentary inverse shape of a virtual model; wherein the plurality of fixed single tooth jigs are configured for placement of orthodontic brackets that correspond to the virtual orthodontic brackets on teeth of the patient thereby enabling bonding of the orthodontic brackets to the teeth at desired locations.

2. The tooth attachment placement device of claim 1 , wherein the upper spline and the lower spline comprise snap points configured for breaking sections of the upper spline and/or the lower spline apart.

3. The tooth attachment placement device of claim 1 , wherein each of the plurality of single tooth jigs comprises a cap, a metal bracket holder, and an O-ring.

4. The tooth attachment placement device of claim 1 , wherein the tooth attachment placement device is formed from a non-flexible biocompatible material.

5. The tooth attachment placement device of claim 1 , wherein the tooth attachment placement device is formed from a semi-flexible material or a flexible material.

6. The tooth attachment placement device of claim 1 , wherein at least two of the plurality of single tooth jigs are of different widths.

7. The tooth attachment placement device of claim 1 , further comprising over mold retention pegs attached to and extending from at least one of the upper spline and the lower spline.

8. The tooth attachment placement device of claim 1 , wherein the tooth attachment placement device comprises clear/transparent or translucent material for carrying ultra-violet light for curing bracket pads attached to surfaces of the teeth.

9. The tooth attachment placement device of claim 8 , wherein the upper spline and the lower spline comprise clear/transparent or translucent material for carrying ultra-violet light for curing bracket pads attached to the surfaces of the teeth.

10. The tooth attachment placement device of claim 8 , wherein the upper spline and the lower spline are of tubular form for carrying ultra-violet light for curing bracket pads attached to the surfaces of the teeth.

11. The tooth attachment placement device of claim 1 , wherein each of the plurality of single tooth jigs includes a tooth number affixed on the single tooth jig.

12. The tooth attachment placement device of claim 1 , further comprising a patient identifier.

13. The tooth attachment placement device of claim 1 , further comprising at least one tooth-sized gap between single tooth jigs.

14. The tooth attachment placement device of claim 1 , wherein the tooth placement device is created with generative manufacturing technologies.

15. The tooth attachment placement device of claim 1 , wherein the plurality of fixed single tooth jigs are in a fixed position.
