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: 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: 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: 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: 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.
