Estimating the term…
A dental attachment placement device comprises a plurality of articulated registration elements shaped for placement on a plurality of teeth, which can facilitate placement, accommodate tooth movement, and improve alignment of the registration elements with the teeth, so as to accurately position an attachment for placement. The plurality of registration elements may comprise one or more attachment supports and one or more retention supports extending from the plurality of registration elements. A dental attachment can be removably coupled to the attachment support. The plurality of registration elements and attachment supports may be located on opposing sides of one or more teeth in order to maintain placement prior to adhering the attachment to the tooth. In some embodiments, each of the plurality of registration elements comprises a tooth registration surface shaped to engage the tooth with a specific position and orientation for accurate positioning of the attachment.
An orthodontic device, comprising:
An orthodontic device, comprising:
The orthodontic device of claim 12, wherein a diameter of the ball of the first coupling is larger than a diameter of the aperture of the second coupling.
The orthodontic device of claim 13, wherein the first and second couplings are fabricated together with the ball of the first coupling captured within the socket of the second coupling.
An orthodontic device, comprising:
The orthodontic device of claim 20, wherein the coupling comprises one or more of a spring, a resilient member, a joint, a ball joint, or a heim joint.
The orthodontic device of claim 20, wherein each of the plurality of registration elements comprises a tooth registration surface, the tooth registration surface comprising a recess sized and shaped to receive a corresponding tooth.
The orthodontic device of claim 22, wherein the tooth registration surface comprises a tooth mating surface, the tooth mating surface shaped to approximate the contour of the tooth.
The orthodontic device of claim 23, wherein the tooth mating surface of each of the plurality of registration elements is sized and shaped to fix an orientation and a translational position of said each of the plurality of registration elements on a respective tooth.
