The method can also include generating a plurality of intermediate tooth arrangements configured to adjust the patient’s teeth from the initial tooth arrangement toward the target tooth arrangement. The method can further include generating instructions to output a visualization showing a difference in tooth mass between at least one intermediate tooth arrangement of the plurality of intermediate tooth arrangements and the target tooth arrangement.

Provided is a data processing method using a data processing apparatus. The data processing method includes obtaining a 3D oral model including 3D scan data of an object; and generating a prosthesis for the object based on the 3D scan data of the object according to a module selected from a plurality of modules.

Methods of administering a quantity of adhesive to bond orthodontic brackets is disclosed herein. The quantity of adhesive to bond a selected bracket to a tooth at a specific location thereon can be calculated based on a known geometry of the selected bracket and a digital model of the patient's teeth. A instruction guide can visually indicate with a graphic the amount of adhesive to dispense from a syringe or other device to bond the selected bracket to the surface of the tooth at a specific location planned in the digital model.

Systems for chronologically tracking patient dental treatment modalities for a plurality of patients including dental aligner production and manufacture. A device may display a three-dimensional model of the series of the modified teeth positions from the starting teeth positions, the three-dimensional model being used to fabricate a dental device that causes the starting teeth positions of the patient to physically change to the desired teeth positions according to the treatment plan. A device may display a graphical user interface for the chronologically tracking patient dental treatment modalities for the plurality of patients, the graphical user interface for the chronologically tracking patient dental treatment modalities for the plurality of patients comprising: a first row of cells containing a first subject heading displaying pending review status, the pending review being a status of doctor evaluation of the treatment plan for the patient dental treatment modalities.

A method includes to receive, via a computing device, data representing a plurality of teeth, identify data indicating which of the plurality of teeth are unerupted or erupting, predict at least one characteristic of a tooth of the unerupted or erupting teeth after they have fully erupted using one or more tooth eruption prediction factors, generate new data representing the unerupted or erupting teeth in multiple states of eruption based upon the predicted at least one characteristic of the fully erupted teeth, and generate a series of incremental tooth arrangements with the new data to define a proposed orthodontic treatment based on the new data representing the unerupted or erupting teeth in multiple states of eruption.

The present disclosure provides methods, computing device readable medium, devices, and systems having a dental attachment placement structure. One dental attachment placement apparatus includes a body having an attachment placement surface that is to be placed on an attachment affixing surface of a tooth and wherein the attachment placement surface includes a portion that is shaped to allow placement of an attachment at a particular position on the affixing surface of the tooth and a portion of the body having a contour that is shaped to correspond with a contour of an alignment surface of a tooth and when the contour of the body and the corresponding contour is aligned, the attachment is located at the particular position and can be secured to the affixing surface of the tooth.

Systems, methods, and devices for improved orthodontic treatment of a patient's teeth are provided herein. In some embodiments, a method includes determining an appliance geometry for a dental appliance. The appliance geometry can include a first region representing a shell comprising a plurality of teeth receiving cavities, and a second region representing at least one integrally formed component to be integrally joined to the shell. The method can also include generating instructions including a first digital representation of the shell based on the first region, and a second digital representation of the at least one integrally formed component based on the second region. The method can further include transmitting the instructions to a fabrication system configured to additively manufacture the dental appliance by fabricating the shell based on the first digital representation, concurrently with fabricating the at least one integrally formed component based on the second digital representation.

The present disclosure provides method, computing device readable medium, and devices for dental appliances with repositioning jaw elements. An example of a method can include identifying a misaligned jaw of a patient from a virtual image of the patient's jaw, providing a treatment plan for the patient including a virtual model of a dental appliance having a first shell and a second shell configured to reposition at least one tooth of the patient, and adjusting the position of the repositioning jaw elements on the first shell and the second shell to comply with a number of constraints. The virtual model of the dental appliance including repositioning jaw elements on the first shell and the second shell configured to move a position of the misaligned jaw of the patient.

Systems and methods for generating a 3D model of a dentition are disclosed herein. A method includes generating a first 3D model of a dentition including a plurality of model teeth. The method includes receiving at least one digital representation comprising patient teeth. The method includes determining a virtual camera parameter. The virtual camera parameter corresponds with a camera used to capture the digital representation. The method includes comparing, based on the virtual camera parameter, a first position of a model tooth with a position of a corresponding patient tooth of the digital representation. The method includes moving the model tooth from the first position to a second position. The second position is based on the position of the corresponding patient tooth. The method includes generating a second 3D model comprising the model tooth of the first 3D model in the second position.

The present disclosure provides methods, devices, systems, and computer-implemented methods for forming and placing attachments for use with dental appliances, and more particularly to the design, manufacture, and use of three-dimensionally printed attachment templates for use with orthodontic devices. Dental attachment templates include a cavity with one or more openings for injecting and bonding attachment material directly on a patient's tooth, which allow accurate placement of the attachments while providing the dental practitioner flexibility during the attachment forming process. Digital dental attachment template model techniques can be used to accurately place the cavity and opening.
