    • In a preferred embodiment of the invention, 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.

    • In a preferred embodiment of the invention, an interface attachment device which is customized on one side for placement on a patient's tooth surface and locked on to the bottom or base of a bracket on the other side is disclosed. The combination of the interface attachment device and the bracket is bonded to the surface of a tooth for an orthodontic treatment of the patient. One or more interface attachment devices, with or without brackets, can be precisely placed and bonded to the corresponding surfaces of one or more teeth of a patient using a tooth attachment placement device created for the patient.The locking mechanism between the interface attachment and the bracket can be (a) form-locked, i.e. male/female arrangement, (b) friction-locked (i.e. using spring, magnetism, shape memory phase shift, shrinkage, etc.), (c) combination of (a) and (b), or (d) any other type. The interface attachment can be attached to the tooth surface by any kind of adhesive or composite material.The interface attachment device can be manufactured using generative manufacturing technologies; computer numerically controlled machining technologies; or other manufacturing technique suitable for low volume, high precision, custom parts. The interface attachment device can also be made by any additive manufacturing technology such as 3D printing.
    • 在本发明的一个优选实施例中,公开了一种界面附接装置,其在一侧被定制以放置在患者的牙齿表面上并锁定在另一侧的托架的底部或底部。 界面附接装置和支架的组合结合到牙齿的表面,用于患者的正畸治疗。 具有或不具有支架的一个或多个界面附接装置可以使用为患者创建的牙齿附着装置被精确地放置并结合到患者的一个或多个牙齿的相应表面。 接口连接件和支架之间的锁定机构可以是(a)锁定,即公/母布置,(b)摩擦锁定(即使用弹簧,磁性,形状记忆相移,收缩等),( c)(a)和(b)的组合,或(d)任何其他类型的组合。 界面附件可以通过任何种类的粘合剂或复合材料附着到牙齿表面。 接口连接装置可以使用生成制造技术制造; 计算机数控加工技术; 或适用于低体积,高精度,定制部件的其他制造技术。 界面连接装置也可以通过任何添加剂制造技术如3D打印制成。
