  • Patent number: 12347546
    Abstract: The invention relates to a method for determining whether a tooth is correctly shaped and oriented to avoid interference with another tooth using virtual articulation. The method comprises a) receiving data indicative of a virtual dentition of an oral cavity of a patient by a computing device, the data indicative of the virtual dentition including data indicative of at least one of a virtual mandibular arch representing a mandibular arch of the patient or a virtual maxillary arch representing a maxillary arch of the patient; b) receiving data indicating a selected point on the virtual dentition of the oral cavity; and c) determining a tangent vector indicating a direction of motion of the selected point and determining whether the orientation of a tooth of the virtual dentition or the shape of the tooth is correctly shaped and oriented based on the determined tangent vector, wherein the tangent vector is based on a rotational axis of the virtual mandibular arch.

  • Patent number: 12239507
    Abstract: An example removable dental appliance includes an appliance body configured to at least partially surround a plurality of teeth of a dental arch of a patient. The appliance body includes a shell shaped to engage a tooth in an initial position and a gingival ridge extending from a mesial interproximal region along a gingival edge of the shell to a distal interproximal region. The gingival ridge is configured to engage a lingual or labial surface of the tooth below a height of contour of the tooth to enable the appliance body to apply a force vector at a contact point on the tooth to cause movement of the tooth toward a desired position of the tooth when the removable dental appliance is worn by the patient.

  • Publication number: 20240173101
    Abstract: A method for determining orthodontic brackets in order to use standard brackets or a combination of standard and custom brackets. The method determines which teeth in a digital 3D model of teeth have surfaces that will virtually fit to a base of a standard bracket within a tolerance. For those teeth that will virtually fit to one of the standard brackets, each of the teeth are associated with the corresponding standard bracket for later placement of the brackets on the surfaces of the patient's teeth. The method also identifies the teeth in the digital 3D model of teeth that will not virtually fit to a standard bracket, and brackets with custom bases can be designed and made for those teeth.

  • Publication number: 20240033044
    Abstract: A method includes wire driven phase in which a plurality of attachments are bonded to teeth, the attachments including a wire-retaining region and an engagement region. The engagement region has a shoulder configured to releasably engage a corresponding indentation in an aligner tray. An archwire is inserted in to the wire-retaining regions to move a first malaccluded tooth from a first position to a second position. An aligner phase follows the wire driven phase, in which the archwire is removed, and an aligner tray is applied over the teeth of the patient. The aligner tray includes cavities shaped to receive and resiliently position the first maloccluded tooth from the second position to a third position, and further includes indentations configured to releasably engage at least a portion of the engagement regions on the attachments.

  • Publication number: 20240008959
    Abstract: An indirect bonding device includes a first tray and a second tray. The first tray is configured to be detachably coupled to a tooth having a tooth surface. The second tray is configured to be detachably coupled to the first tray. The first tray includes a cavity at least partially extending from a first inner surface to a first outer surface along a longitudinal axis. An orthodontic appliance is at least partially and detachably received within the cavity. An adhesive layer is disposed on a base surface of the orthodontic appliance. Upon detachable coupling of the first tray to the tooth, the adhesive layer is spaced apart from the tooth surface. Furthermore, upon detachable coupling of the move the orthodontic appliance towards the tooth surface, such that the adhesive layer contacts the tooth surface.

  • Patent number: 11517272
    Abstract: A system and method for simulating orthodontic treatment using augmented reality. An electronic image of a user's face is received from a digital camera, and a region of interest in the image is identified where the region includes the user's teeth. Virtual orthodontic appliances are placed on the user's teeth in the image, and the user's image with the virtual orthodontic appliances is displayed on an electronic display device. The method occurs in real-time to provide the user with the augmented image simulating treatment when or shortly after the image of the user is received. The system and method can display a 3D representation of the user's face augmented with the virtual appliances. The user's augmented image or 3D representation can also be supplemented for display with an image or model of the user's facial anatomy such as an x-ray or a cone beam computed tomography image.
