Abstract: The current document is directed to methods and systems for monitoring a dental patient's progress during a course of treatment. A three-dimensional model of the expected positions of the patient's teeth can be projected, in time, from a three-dimensional model of the patient's teeth prepared prior to beginning the treatment. A digital camera is used to take one or more two-dimensional photographs of the patient's teeth, which are input to a monitoring system. The monitoring system determines virtual-camera parameters for each two-dimensional input image with respect to the time-projected three-dimensional model, uses the determined virtual-camera parameters to generate two-dimensional images from the three-dimensional model, and then compares each input photograph to the corresponding generated two-dimensional image in order to determine how closely the three-dimensional arrangement of the patient's teeth corresponds to the time-projected three-dimensional arrangement.

Abstract: Embodiments are provided for digital dental modeling. One method embodiment includes receiving a three-dimensional data set including a first jaw and a second jaw of a three-dimensional digital dental model and receiving a two-dimensional data set corresponding to at least a portion of the first jaw and the second jaw. The method includes mapping two-dimensional data of the two-dimensional data set to the three-dimensional digital dental model by transforming a coordinate system of the two-dimensional data to a coordinate system of the three-dimensional data set. The method includes positioning the first jaw with respect to the second jaw based on the two-dimensional data mapped to the three-dimensional data set. The method includes using at least a portion of the two-dimensional data mapped to the three-dimensional data set as a target of movement of the first jaw with respect to the second jaw in the three-dimensional digital dental model.

Abstract: Methods, systems and non-transitory computing device readable media for bite setting in dental treatment planning. In some examples, the methods may include using images and a three-dimensional (3D) model of a dentition. Points may be marked on the 3D model corresponding to points marked in the images of first and second jaws in the different relative positions. A pivot point and/or a range of motion of the first and second jaws may be based on the marked points. Forces may be repeatedly applying on the points of the 3D model to move the first jaw with respect to the second jaw using the determined pivot point and/or range of motion until the first jaw ceases moving, thereby indicating that a stable bite position has been achieved. The forces on the points of the 3D model may be provided for a dental treatment plan for the dentition.

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.
