Abstract:

Systems, methods, and devices for improved orthodontic treatment of a patient's teeth are provided herein. In some embodiments, a method includes determining an appliance geometry for a dental appliance. The appliance geometry can include a first region representing a shell comprising a plurality of teeth receiving cavities, and a second region representing at least one integrally formed component to be integrally joined to the shell. The method can also include generating instructions including a first digital representation of the shell based on the first region, and a second digital representation of the at least one integrally formed component based on the second region. The method can further include transmitting the instructions to a fabrication system configured to additively manufacture the dental appliance by fabricating the shell based on the first digital representation, concurrently with fabricating the at least one integrally formed component based on the second digital representation.

International Classification:

A61C 13/00
A61C 7/00
A61C 7/08

Abstract:

A support is coupled to an appliance to decrease warpage. The support may comprise a plurality of extensions coupled to the appliance to decrease warpage. The extensions can be coupled to the appliance at one or more of many locations, such as on an occlusal surface, a wall, an edge or an interior of the appliance. In some embodiments, the extensions are coupled to walls of the appliance such as a buccal wall and a lingual wall, and the extensions can be coupled to the walls of the appliance near edges of the walls, such as a gingivally facing edges of the walls that are oriented toward the gingiva when the appliance is worn.

International Classification:

A61C 7/08

Abstract:

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.

Abstract:

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. An orthodontic device may include a plurally of registration element. A plurality of first flexible arms may extend from each registration element on a lingual side. The first flexible arm may have a connected end and a distal end. The distal end may be configured to extend at least part way over the tooth and apply a lingual force to bias the registration element against the tooth. A plurality of attachment supports may each be located on a buccal side of the plurally of registration elements and include an attachment frame that is releasably coupled to an attachment.

Abstract:

Strategies that reduce shrinkage and ultimately warping of parts that are directly fabricated from photopolymer resins. This increases the accuracy of directly fabricated parts, which is essential for patient specific applications. Implementing these strategies can reduce the need for directly fabricated parts to have supporting structures, which can reduce pre-processing and post-processing steps and facilitate an easier route for production level scale of additive manufacturing.
