Abstract: Methods of forming a dental appliance. The methods may include partially curing a prepolymer mixture into a semi-solid polymer material having a first shape that is a sheet. The semi-solid polymer material may be placed over a dentition mold, wherein the semi-solid polymer material may take on a second shape corresponding to a shell having one or more cavities for receiving one or more teeth. The semi-solid polymer material may be fully cured by exposure to energy until the semi-solid polymer material thermosets in the second shape.

Abstract: Patterned dental positioning appliances including a shell having cavities shaped to receive and exert repositioning forces on one or more teeth of a subject's dentition. The shell may include a first cavity having a first raised pattern configured to exert a first force on a first tooth of the one or more teeth, and a second cavity having a second raised pattern configured to exert a second force on a second tooth of the one or more teeth. The second raised pattern may be different than the first raised pattern.

Abstract: Dental appliances and methods for expanding the lower dental arch. The appliances may be removable mandibular expander devices for efficient arch expansion while being comfortable to wear and easy to use. The appliances may include a lingual portion that is shaped and sized to apply an expansion force to lingual surfaces of one or more teeth. The shape and size of the lingual portion may be configured to distribute the forces among posterior and/or anterior teeth. A series of expander devices may be designed to provide the expansion forces in a stepwise fashion toward a target lower arch configuration according to a treatment plan

Abstract: A method includes to receive, via a computing device, data representing a plurality of teeth, identify data indicating which of the plurality of teeth are unerupted or erupting, predict at least one characteristic of a tooth of the unerupted or erupting teeth after they have fully erupted using one or more tooth eruption prediction factors, generate new data representing the unerupted or erupting teeth in multiple states of eruption based upon the predicted at least one characteristic of the fully erupted teeth, and generate a series of incremental tooth arrangements with the new data to define a proposed orthodontic treatment based on the new data representing the unerupted or erupting teeth in multiple states of eruption.

Abstract: The present disclosure provides methods, devices, systems, and computer-implemented methods for forming and placing attachments for use with dental appliances, and more particularly to the design, manufacture, and use of three-dimensionally printed attachment templates for use with orthodontic devices. Dental attachment templates include a cavity with one or more openings for injecting and bonding attachment material directly on a patient's tooth, which allow accurate placement of the attachments while providing the dental practitioner flexibility during the attachment forming process. Digital dental attachment template model techniques can be used to accurately place the cavity and opening.

Abstract: A series of a palatal expanders increasing width can be used to gradually expand a patient's palate. Each palatal expander may have a palatal region flanked by teeth regions. The palatal region can have a plurality of anchor-receiving features (e.g., anchor interfaces) that allow the palatal expander to be attached to temporary anchorage device anchors that have been implanted into the patient's maxilla.
