Abstract: Systems and methods for monitoring a dental patient's progress during treatment. A camera coordinate system of a virtual camera is aligned to be coincident with a world coordinate system of a 3D) model representing a expected configuration of the patient's teeth at a particular time during treatment. One or more expected 2D images generated by mapping points from the 3D model to points on an image plane of the virtual camera. One or more 2D images of the patient's teeth taken at the particular time during treatment are compared to the expected 2D images to determine whether a configuration of the patient's teeth is within a threshold level of correspondence to the expected configuration of the patient's teeth. An indication about whether the dental treatment is proceeding as expected based on whether the configuration of the patient's teeth is within the threshold level can be provided.
