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.

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.

Abstract: A series of appliances including a first shell and a second shell can be designed to incrementally implement a treatment plan. The first and second shells can have cavities designed to receive teeth of a jaw. The first shell can be designed to interface with a first surface of a plurality of surfaces of an attachment structure to provide a first engagement force specific to a first stage of the treatment plan. The second shell can be designed to interface with a second surface of the plurality of surfaces of the attachment structure attached to the at least one tooth of the first jaw to provide a second engagement force specific to a second stage of the treatment plan.

Abstract: A system for correcting class III malocclusions is disclosed. The system may include a maxilla appliance having tooth receiving cavities shaped to receive teeth of the maxilla and a first coupling for receiving an elastic. The system may also include a mandibular appliance having tooth receiving cavities shaped to receive teeth of the mandible. In some embodiments, the system includes a class III corrective appliance having a first mount shaped to engage with the mandibular arch of the patient and having a second coupling shaped to receive the elastic.

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: 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: Methods and apparatuses for designing dental attachments. Methods may include generating a 3D model of a dental attachment formation apparatus based on a virtual dentition. Generating the 3D model may include: forming a body having a surface shaped to conform to contours of the virtual dentition, where the body is configured to include a light transmissive portion and an opaque portion; forming one or more wells in the body, wherein each well is shaped to receive a dental attachment; and forming a light path through the body to the one or more wells, where the opaque portion of the body is arranged with respect to the light transmissive portion of the body to keep light from illuminating portions of the body other than the one or more wells.
