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: 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: 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.

Abstract: Methods and systems for determining a dental treatment difficulty in digital treatment planning. The methods may include determining changes in position of first and second teeth between initial and target dental models relative to an arch line of the initial dental model of a patient's dentition. The changes in position may be determined by projecting first and second distances between initial and subsequent positions of the teeth onto the arch line. A treatment difficulty of anterior-posterior correction may be determined by comparing a calculated average change in position to one or more threshold changes in position. The digital treatment plan may be adjusted when the average change in position is greater than at least one of the one or more threshold changes in position.
