Methods and systems for IPR planning. One method includes identifying an overlap between a first tooth and a second tooth in a patient's dentition at a target position of a treatment plan; identifying first and second ridge endpoint reference lines on each of the first tooth and the second tooth; calculating a distance difference between the first and second ridge endpoint reference lines; determining that the distance difference is outside a threshold difference; revising the treatment plan by adding one or more stages to the treatment plan where the distance difference between the first and second ridge endpoint reference lines is within the threshold difference; and prescribing IPR on one or both of the first and second teeth at the one or more additional stages of the treatment plan.

Methods and systems for interproximal reduction planning

The example systems, methods, and/or computer-readable media described herein help with design treatment plans for orthodontic treatments. Treatment templates reflecting a user's treatment preferences are expressed in a domain-specific treatment language and include treatment protocols. Orthodontic treatment plans are customized based on the treatment templates and a physical condition of the patient. Treatment appliances are fabricated based on the customized orthodontic treatment plans.

Systems and methods for treatment using domain-specific treatment protocols

Method of manufacturing a series of aligners for an orthodontic and/or dental treatment of a patient's teeth. In particular, described herein are methods of manufacturing a series of aligners that includes displaying images of the patient's teeth at the final stages for a subset of the treatment plans from the array of treatment plans in a manner that allows the user to select between the different treatment plans in order to select a treatment plan for fabrication.

Methods of manufacturing dental aligners

Orthodontic and/or dental treatment planning methods and apparatuses. In particular, described herein are methods of generating a plurality of orthodontic treatment plans digitally using a hierarchy of bounding boxes enclosing the plurality of 3D shapes to avoid collisions during treatment.

Treatment plan generation using collision detection by shape filling

Methods and systems are provided for manufacturing an appliance for correcting malocclusions of a patient's teeth. The method may include measuring the positions of a patient's teeth and receiving tooth movement constraints. The method may also include generating an initial treatment plan based on the measured tooth positions and the tooth movement constraints and measuring the malocclusions of the patient's teeth for one or more types of dental malocclusions. The method may also include generating a plurality of treatment plans from the initial treatment plan based on the measured malocclusion and generating a model of an appliance for each stage of the treatment plan. The method may also include generating instructions for fabricating the appliance for each stage of the treatment plan based on the model of the appliance for each stage of the treatment plan.

Systems, methods, and apparatus for correcting malocclusions of teeth

Methods and systems including: receiving one or more 2D images of a patient's face including a depiction of the patient's teeth in an initial arrangement; extracting teeth contours of the patient's teeth from within the mouth region of the one or more received 2D images of the patient's face; generating, using a neural network, a 2D rendering depicting a post-treatment arrangement of the patient's teeth based on the one or more received 2D images; generating a realistic composite 2D image depicting the patient's face with the 2D rendering depicting the post-treatment arrangement of the patient's teeth; and sending the realistic composite 2D image for display on a user interface of an output device.

Generating a virtual patient depiction of an orthodontic treatment

A method may include: receiving an image of a mouth region of a patient's face; extracting teeth contours within the image of the mouth region of the patient's face; locating a mouth opening within the image of the mouth region of the patient's face; extracting the tooth contours from a 3D model of the patient's teeth; and aligning the tooth contours from the 3D model with the tooth contours of the teeth within the image of the mouth region of the patient's face.

Automated 2D/3D integration and lip spline autoplacement

The present disclosure includes computing device related, systems, and methods for IPR planning as described herein. One method includes identifying a first tooth and a second tooth in a digital dental model with an overlap in a target final position in a treatment plan and identifying a reference line on each of the first tooth and the second tooth; revising the treatment plan wherein a position of each of the first tooth and the second tooth is determined in which the reference line of each of the first tooth and the second tooth are aligned and the first tooth and second tooth are not overlapping; and prescribing IPR based on the determined position of each of the first tooth and the second tooth.

Interproximal reduction planning

In various implementations, computer-implemented method, such as one executed on a computer system or on instructions stored on computer-readable media may include: receiving from a user device associated with a user, a request to access one or more treatment plans for patient; identifying a treatment template for user, the treatment template representing treatment preferences of the user, the treatment template being expressed according to treatment domain-specific protocols; processing the treatment template with the treatment domain-specific protocols to convert one or more parts of the treatment template into one or more runtime elements that interactively display customized user interface elements related to the treatment plan, the customized user interface elements configured to provide one or more customized user interactions with the treatment plan in accordance with the treatment preferences of the user; and providing instructions to display the one or more runtime elements on the user device.

Systems and methods of managing customized run display elements with treatment templates based on treatment domain-specific protocols

The present disclosure provide for methods of planning restorative procedures. Methods may involve identifying an initial position of a patient's teeth based on a digital representation of the patient's teeth, and determining one or more candidate orthodontic positions for the patient's teeth, wherein each of the one or more candidate orthodontic positions is a target position of the patient's teeth being considered. Methods may further involve virtually modeling a first restorative object at a first evaluated restorative object position on one of the patient's teeth, evaluating a first amount of tooth mass removal corresponding to the first restorative object based on the first evaluated restorative object position and one of the candidate orthodontic positions, and determining a final orthodontic position and a final restorative object position based on the first amount of tooth mass removal.

Restorative smile visualization through digital treatment planning

Orthodontic and/or dental treatment planning methods and apparatuses. In particular, described herein are methods of generating a plurality of potential treatment plan variations for the concurrent and interactive review of the treatment plan variations. Each variation may be optimized to best address the user's treatment goals, as well as approximating as closely as possible an ideal or target final position. Also described herein are orthodontic and/or dental treatment planning methods and apparatuses that allow a user to form, modify, and select a treatment plan from a plurality of different treatment plans, in real time.

Automatic treatment planning

A computer-implemented method for generating a virtual depiction of an orthodontic treatment of a patient is disclosed herein. The computer-implemented method may involve gathering a three-dimensional (3D) model modeling the patient's dentition at a specific treatment stage of an orthodontic treatment plan. An image of the patient's face and dentition may be gathered. A first set of reference points modeled on the 3D model of the patient's dentition and a second set of reference points represented on the dentition of the image of the patient may be received. The image of the patient's dentition may be projected into a 3D space to create a projected 3D model of the image of the patient's dentition. Based on a comparison of the first reference points and projections of the second set of reference points, a modified image of the patient may be constructed and/or modeled.
