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 apparatuses (e.g., systems) and methods for automatically assessing a segmented 3D dental model. The segmented 3D dental model may be classified by a trained machine learning classifier (a trained neural network). In some cases, the segmented 3D dental model may be classified as a passing (acceptable) or failing (unacceptable) model. The machine learning classifier may be trained with labeled 3D dental models that illustrate passing and failing segmented 3D dental models.

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.
