Abstract: A method may include obtaining a plan model of a patient's teeth, obtaining a tracking model of the patient's teeth representing an arrangement at an intermediate stage of a treatment plan, generating a comparison of the plan model with the tracking model using a coarse to fine volume 3D array to represent one or both of the plan model and the tracking model, detecting one or more positional differences between anatomical reference shapes and surface features of the plan model and corresponding anatomical reference shapes and surface features of the tracking model based on the comparison and using the coarse to fine volume 3D array, generating a modified treatment plan based on the one or more detected positional differences, and fabricating a dental appliance based on the modified treatment plan.

Abstract: Methods and systems for analysis of dental attachments. The dental attachments may be used in conjunction with a dental aligner worn by the patient to move the patient's teeth in accordance with a clinical treatment plan. A series of images may be taken while the patient is wearing the dental aligner. The series of images may be analyzed to confirm that the dental attachment(s) are present and bonded on the patient's tooth/teeth. Additionally or alternatively, the series of images may be analyzed to assess an interaction between the dental aligner and the attachment(s) bonded on the patient's tooth/teeth to determine if the attachment(s) have a defect. An indication of the status of the attachment(s) may be output to a user.

Abstract: Palatal expander apparatuses for expanding a patient's palate (“palatal expanders”) and methods of using and making them. These palatal expanders may be configured to have a variable surface smoothness on one side (e.g., the lingual-facing surface) compared to the opposite side (e.g., the palatal-facing surface). These palatal expanders may be configured to have a varying thickness in the palatal region. These palatal expanders may be adapted for ease in removal by the patient or caregiver (e.g., including a hinged region and/or detachment region, and/or including a thinner buccal side then occlusal side, etc.).

Abstract: Dental attachment positioning apparatuses and methods of use. A dental attachment apparatus may include an orthodontic attachment having a surface shaped to conform to a contour of a buccal surface of a tooth, and one or more registration surfaces that are shaped to conform to one or more occlusal surfaces of the patient's teeth. The one or more registration surfaces may be configured to aid in proper positioning or orientation of the orthodontic attachment. When the attachment positioning apparatus is placed on the patient's dentition, the orthodontic attachment is positioned at a specified location with respect to the buccal surface of the tooth.

Abstract: Embodiments are provided for using an individualized orthodontic treatment index. One method embodiment includes receiving an initial virtual dental model from a first scan of a patient's dentition, modifying the initial virtual dental model to create a target virtual dental model according to a treatment goal, assigning a number of dental references to the target virtual dental model, receiving a treatment outcome virtual dental model from a second scan of the patient's dentition, mapping the number of dental references from the target virtual dental model to a treatment outcome virtual dental model, and calculating an individualized treatment index score for the treatment outcome virtual dental model according to one or more differences between the target virtual dental model and the treatment outcome virtual dental model based on the number of dental references.

Abstract: Methods and systems for generating a three-dimensional occlusogram are disclosed. One method includes determining a virtual three dimensional (3D) mesh model object of at least one tooth of a patient and displaying the determined virtual 3D mesh model object of at least one tooth of a patient wherein the 3D mesh model object includes a plurality of data sets associated with a set of occlusal information for the at least one tooth of the patient.

Abstract: A dual aligner assembly including a plurality of aligners, including a first aligner and a second aligner. The first aligner has a first shape corresponding to a set of target tooth positions and applies an orthodontic force against a set of target teeth. The first orthodontic force generates movement of the set of target teeth to the set of target tooth positions. The second aligner has a second shape corresponding to a combination of current tooth positions of the set of target teeth, the set of target tooth positions, and a thickness of the first aligner. The second aligner partially encloses the first aligner and provides an anchor for at least a portion of the first aligner. Via the anchor, a combination of the first aligner and the second aligner provides an orthodontic force that prevents the set of target teeth from moving to unwanted tooth positions during orthodontic treatment.

Abstract: Methods and apparatuses for 3D imaging to measure the shape of orthodontic aligners, teeth, and other oral structures simultaneously, in-vivo or in-vitro. These methods and apparatuses may be used to determine contact locations of aligners with teeth and/or teeth with other teeth with very high precision, including determining the size of gaps where they are not in contact. These measurements may be used design, modify or replace an aligner and/or to verify aligner fit. 3D models of the whole aligner and teeth may be generated.
