Abstract: Systems, methods, and devices for computer-aided design, digital treatment planning, and direct additive manufacturing of dental appliances are provided. In some embodiments, a method includes receiving a treatment plan for a patient's teeth, the treatment plan specifying a target arrangement for the teeth and a plurality of treatment stages to reposition the teeth from an initial arrangement toward the target arrangement. The method can include identifying appliance design parameters for one or more dental appliances to implement at least one treatment stage of the plurality of treatment stages. The appliance design parameters can include one or more manufacturability parameters corresponding to an additive manufacturing process to be used to directly fabricate the one or more dental appliances. The method can further include determining an appliance geometry for the one or more dental appliances using the set of appliance design parameters.

Abstract: The present disclosure provides methods, computing device readable medium, devices, and systems having a dental attachment formation structures. One dental appliance includes a body having a first surface shaped to abut an exterior surface of a tooth and a well portion of the first surface shaped to form an attachment that is to be attached to the exterior surface of the tooth, a release layer formed over a surface of the well to allow the attachment to be removed from the well, and an attachment material that is used to form the attachment positioned within the well.

Abstract: Orthodontic systems and related methods are disclosed for designing and providing improved or more effective tooth moving systems for eliciting a desired tooth movement and/or repositioning teeth into a desired arrangement. Methods and orthodontic systems include the generation of an overcorrection in the tooth-receiving cavities of an appliance worn in the dentition. The overcorrection may provide an improved and more accurately applied force or moment applied to a tooth. The overcorrected force or moment can move a tooth closer to a desired position than if not overcorrected as sufficient force can still applied to the tooth as it gets closer to the desired position. The overcorrected force or moment may also better target the root of the tooth where the biological response to tooth movement occurs. The overcorrection may be calculated in various ways as described herein.

Abstract: Systems and methods of generating an orthodontic model are disclosed. The method may include: generating an initial model of a patient dentition; generating a target model of the patient dentition; defining a plurality of caps and a plurality of links, wherein each link connects two of the plurality of caps; generating a relaxed model of a dental appliance from the plurality of caps and the plurality of links; generating a deformed model of a dental appliance from the plurality of caps and plurality of links; and determining a plurality of movements, wherein the plurality of moments transform the relaxed model to the deformed model and wherein the moments are configured to direct the patient dentition from the initial model to the target model.

Abstract: The present disclosure includes computing device related, systems, and methods for identifying force placed on a tooth are described herein. One method includes receiving initial orthodontic data (IOD) including teeth data; creating a virtual set of teeth from the IOD; receiving dental appliance information including at least one of dental appliance material properties and characteristics; virtually placing a dental appliance, formed from the dental appliance information, onto the virtual set of teeth; and determining one or more forces applied to the teeth based on information from the IOD and dental appliance information.

Abstract: Methods and apparatuses for 3D imaging (including 3D optical coherence tomography 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.

Abstract: Orthodontic systems and related methods are disclosed for designing and providing improved or more effective tooth moving systems for eliciting a desired tooth movement and/or repositioning teeth into a desired arrangement. Methods and orthodontic systems of the invention include tooth attachments having improved or optimized parameters selected or modified for more optimal and/or effective application of forces for a desired/selected orthodontic movement. Attachments of the present invention can be customized to a particular patient (e.g., patient-customized), a particular movement, and/or a sub-group or sub-set of patients, and configured to engage an orthodontic tooth positioning appliance worn by a patient, where engagement between the attachment and orthodontic appliance results in application of a repositioning force or series/system of forces to the tooth having the attachment and will generally elicit a tooth movement.
