Abstract: Methods and systems for improving segmentation of a digital model of a patient's dentition into component teeth.

Abstract: A method for determining tooth numbers of teeth within a dental arch includes receiving a digital scan of a patient's dentition, detecting a cusp associated with at least one tooth in the digital scan, where the cusp is detected based at least in part on a radius of a surface of the cusp, matching a molar shape of the at least one tooth, and identifying the patient's molar tooth based on the molar shape.

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: Apparatuses (e.g., systems) and methods for quickly and accurately determining tooth number information associated with a subject's dental data. A stage of a prior treatment plan that most closely matches to a digital model of a subject's current dentition may be used to approximate tooth numbering for the subject's current dentition.

Abstract: Apparatuses (e.g., systems) and methods for quickly and accurately determining tooth axis information associated with a subject's dental data. A stage of a prior treatment plan that most closely matches to a digital model of a subject's current dentition may be used to approximate tooth axis information for the subject's current dentition.

Abstract: Provided herein are systems and methods for automatically segmenting a 3D model of a patient's teeth. A patient's dentition may be scanned. The scan data may be converted into a 3D model, including a sparse voxel representation of the 3D model. Features can be extracted from the sparse voxel representation of the 3D model and input into a machine learning model to train the machine learning model to segment the 3D model into individual dental components.

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: Methods and apparatuses to determine the best (e.g., closest) match between a patient's current or jaw configuration and one actual or intended jaw configurations from a series of jaw configurations for the same patient that were previously generated. These methods and/or apparatuses may be used to transform a prior tooth model, from a prior stage or stages of a treatment plan, into a current tooth arrangement. This may include revising the digital model.

Abstract: Methods and apparatuses for the automatic determination of the quality of a digital three-dimensional (3D) models of a patient's dentition. These methods and apparatuses may determine the if a digital 3D model is of sufficient quality for use in treatment planning and may use a machine learning agent (e.g., neural network) that is trained using a set of defects that are recognized as impacting the quality and/or utility of the digital 3D model for treatment planning of a particular treatment.

Abstract: Methods and apparatuses for adjusting three-dimensional (3D) dental model data of a patient's dentition to detect and remove one or more attachments on a dental structure (e.g., tooth) of the patient's dentition. These methods and apparatuses may be used for generating treatment plans for treating the patient's teeth, including for more accurately and efficiently aligning the patient's teeth.

Abstract: Provided herein are apparatuses (e.g., systems) and methods for assisting in generating and segmenting a 3D dental model of a subject's dentition. A 3D dental model may be generated from a dental scan. The apparatuses described herein can determine if the subject has previously undergone a dental or orthodontic treatment, and the 3D dental model can be compared to prior 3D dental models from the previous treatment(s). In some examples, the 3D dental model can be updated or supplemented with data from the prior 3D dental models.
