    Abstract: The invention relates to a removable dental appliance comprising an appliance body configured to at least partially surround a plurality of teeth of a patient. The appliance body defines a shell configured to receive a tooth of the plurality of teeth in an initial position and a bendable flap integrally formed with the appliance body to extend from a hinge axis of the shell. The bendable flap defines a boundary region extending from a first end of the hinge axis around the bendable flap to a second end of the hinge axis and including an arcuate member. In one specific embodiment, the arcuate member comprises a spring bellows extending away from a plane of the shell. The bendable flap and the arcuate member are configured to apply a force to the tooth to cause movement of the tooth toward a desired position when the removable dental appliance is worn by the patient.

    Abstract: The invention relates to a removable dental appliance comprising an appliance body configured to at least partially surround a plurality of teeth of a patient. The appliance body defines a shell configured to receive a tooth of the plurality of teeth in an initial position and a bendable flap integrally formed with the appliance body to tether the flap to the shell. The bendable flap defines a boundary region around the bendable flap and includes abridge, wherein the bridge extends between the body and the flap at or adjacent the boundary region. In one specific embodiment, the bridge is an arcuate member and includes a spring bellows. The bendable flap and the bridge are configured to apply a force to the tooth to cause movement of the tooth toward a desired position when the removable dental appliance is worn by the patient.

    Abstract: A method to combine dental anatomy data includes, by the use of a computing device: receiving volumetric dental data and superficial dental data; segmenting the crowns of the volumetric dental data from the roots of the volumetric dental data; segmenting the crowns of the superficial dental data from the gingiva of the superficial dental data; transforming superficial dental data of the crowns to substantially align with volumetric dental data of the crowns; stitching the transformed superficial dental data of the crowns to volumetric dental data of the crowns; and outputting for display an image data based on the combined dental data.

    Abstract: Systems and techniques are described for determining at least one of a translational force or a rotational force applied by a dental appliance to a tooth or teeth of a patient. A system includes model teeth configured to represent a portion of a dental arch and receive a dental appliance, a post extending from a first end coupled to a respective tooth to a second end coupled to a base, at least one strain gauge integrally formed on a surface of the post between the first end and the second end, and processor communicatively coupled to the at least one strain gauge and configured to determine at least one of a translational force or a rotational force applied by the dental appliance to the respective tooth.
