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: The present disclosure provides computing device implemented methods, computing device readable media, and systems for adjustment of tooth position in a virtual dental model. Virtual dental modeling can include detecting space and/or collision between posterior teeth of an upper jaw and posterior teeth of a lower jaw in a virtual dental model that has been set in a preliminary target position. An energy function can be defined including the space and/or collision, tooth root movement, and align points. Weights can be assigned for each variable in the energy function. A position of the posterior teeth of the upper jaw and the posterior teeth of the lower jaw can be adjusted in six degrees of freedom to minimize the energy function. The detection, definition, assignment, and adjustment can be repeated until the energy function converges. The weights can be adjusted to reduce the space and/or collision.

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.
