Abstract:
Systems and methods are disclosed for producing a digital model by providing a digital model of a tooth; providing a digital model of at least one attachment device having two or more portions, the digital model of the attachment device having the two or more portions extending through two or more surfaces of the tooth; and positioning the digital model of the attachment device on the digital model of the tooth to produce a combined computerized model.
Abstract:
A package for small parts having a first shipping and/or storage position, a second display position, and a third service position. The package has an areal support which is divided into four section by a transversely extending hinge connection and a longitudinally extending hinge connection. In the first position, the right and left portions of the package are folded over on one another to form a package enclosing the parts. In the second position the areal support is laid open in substantially the same plane where the parts are visible but cannot readily be removed from the package. In the third position, the package is folded back on itself along the longitudinal axis to provide access to the parts.
Abstract:
A dental splint includes upper and lower appliances having cavities shaped to receive teeth on a patient's maxillary and mandibular arches, respectively; and a connection member adapted to fixedly secure the upper and lower appliances together.
Abstract:
Systems and methods are disclosed for forming a pontic in a polymeric shell dental appliance, including providing a polymeric shell dental appliance of the type which is removably placeable over a patient's dentition, said shell having a concave trough which conforms to the teeth when the appliance is placed over the dentition and a location in the trough corresponding to a missing tooth; and depositing a flexible, durably affixed material in the location to form the pontic.
Abstract:
Systems and methods are disclosed for moving teeth by moving a first tooth; and moving a second tooth while isolating the first tooth at a rest position.
Abstract:
A system and method for repositioning teeth in a patient jaw includes an attachment bonded to a tooth. The attachment has at least one force receiving component for receiving a force. A polymeric shell repositioning appliance is positioned over at least some of the teeth in the patient jaw. The polymeric shell has at least one force transmitting component for engaging the force receiving component to form a locus of engagement. The locus of engagement transmits the force and moves but is maintained as the tooth is repositioned. In specific embodiments the locus of engagement is maintained over a substantial range of motion. The force transmitted at the locus of engagement increases in response to the tooth lagging an intended position. A space between the positioned appliance and the tooth permits the tooth to move into an intended position.

Abstract:
Systems and methods are disclosed for performing virtual treatment using one or more dental appliances by receiving a digital model of a dental appliance; selecting a standard position and orientation; and mapping the digital model of the dental appliance to the standard position and orientation.
Abstract:
Systems and methods are disclosed for making an arch expander for a patient by scanning the patient's dentition; fabricating an appliance adapted to be positioned between posterior teeth and a palatal arch, the appliance having first and second movable portions; and providing an expander between the first and second portions of the appliance.
