Abstract: Embodiments are directed to techniques, methods and systems for analyzing orthodontic treatments during treatment and correcting the orthodontic treatments when analysis shows that a patient's actual dentition for a stage of treatment deviates from a planned dentition for the stage of treatment. Analysis may be performed by comparing image data of an actual condition of the patient's dental arch at a stage of treatment to a planned condition of the patients dental arch for the stage of treatment, and identifying clinical signs that the actual condition of the patient's dental arch has a deviation from the planned condition of the patient's dental arch for the stage of orthodontic treatment.

Abstract: Embodiments for determining a dental treatment difficulty are described herein. One method embodiment includes receiving an initial and subsequent position of each of a first tooth and a second tooth and calculating a change in position of each of the first tooth and the second tooth. The method embodiment can also include projecting the changes in position of each of the first tooth and the second tooth onto a reference line and calculating a change in position on the reference line for the first tooth and the second tooth. The method embodiment can further include determining the dental treatment difficulty based on the changes in position on the reference line.

Abstract: Embodiments are provided for tracking teeth movement correction. One method embodiment includes using a set of positioning appliances shaped to move teeth through a number of successive stages of arrangements of an expected teeth arrangement model where each stage corresponds to a particular positioning appliance, mapping a current teeth position based upon positions of a number of physical markers attached to a number of physical teeth, comparing the positions of the number of physical markers with a corresponding number of virtual markers positioned on a number of virtual teeth of a stage in the expected teeth arrangement model, determining whether midcourse correction is needed.

Abstract: 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.

Abstract: Embodiments are provided for digital dental modeling. One method embodiment includes receiving a three-dimensional data set including a first jaw and a second jaw of a three-dimensional digital dental model and receiving a two-dimensional data set corresponding to at least a portion of the first jaw and the second jaw. The method includes mapping two-dimensional data of the two-dimensional data set to the three-dimensional digital dental model by transforming a coordinate system of the two-dimensional data to a coordinate system of the three-dimensional data set. The method includes positioning the first jaw with respect to the second jaw based on the two-dimensional data mapped to the three-dimensional data set. The method includes using at least a portion of the two-dimensional data mapped to the three-dimensional data set as a target of movement of the first jaw with respect to the second jaw in the three-dimensional digital dental model.

Abstract: Provided herein are systems and methods for determining if a 3D tooth model requires trimming or removal of incomplete or missing data (e.g., gingiva covering a portion of a tooth such as a molar). A patient's dentition may be scanned and/or segmented. Features of the patient's teeth can be determined, including a tooth center point of at least three of the patient's teeth. The features of the patient's teeth are used to access a parametric model. A trim plane normal vector is identified for a distal tooth. Trimming of the 3D tooth model is based on the trim plane normal vector.

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.
