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: Methods and systems for taking images of a patient's teeth for tracking a progress of an orthodontic procedure. The methods and systems include a mobile device holder with one or more adjustable stops for providing a compressive force on a mobile device placed therein; a cheek retractor coupled to the mobile device holder; and a user interface on the mobile device indicating whether the mobile device holder is in a correct position relative to the patient's teeth as the mobile device holder is moved while the cheek retractor engages a cheek of the patient to expose the patient's teeth, while taking one or more visual images of the exposed teeth using a camera of the mobile device.

Abstract: Methods and apparatuses for orthodontic treatment planning. A treatment plan may be for a patient's teeth and for a specific dental professional. A set of combined treatment preferences may include a first set of rules converted from a set of textual instructions from the specified dental professional into a domain-specific language specific to the specified dental professional. The textual instructions may include unscripted instructions. A second set of rules may be converted from a set of scripted instructions from the specified dental professional. The scripted instructions may include responses from a script of predefined choices. An orthodontic treatment plan may be generated for the patient's teeth using the set of combined treatment preferences and a digital model of the patient's teeth.

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. Raw dental features, principal component analysis (PCA) features, and/or other features may be extracted and compared to those of other teeth, such as those obtained through automated machine learning systems. A classifier can identify and/or output probability that the 3D tooth model requires trimming. Trimming of the 3D tooth model can be implemented without human intervention.

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: Computer-implemented methods and systems for modeling a patient's tooth. The methods may include generating a clinical crown mesh of the patient's tooth, where the clinical crown mesh includes known surfaces of a clinical crown of the patient's tooth. The methods may also include generating a parametric tooth model representing an average of multiple etalon tooth models of the same tooth type as the patient's tooth, where each of the multiple of etalon tooth models is represented by a mesh having a topical equivalence to a sphere and having no self-intersections. The methods may further include fitting the clinical crown mesh with the parametric tooth model to create an interim tooth model, and morphing the interim tooth model to substantially mimic an anatomical shape of the clinical crown mesh.
