MACHINE LEARNING DENTAL SEGMENTATION SYSTEM AND METHODS USING SPARSE VOXEL REPRESENTATIONS

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.
