    Abstract: A computer or other digital circuitry is used to assist in the creation of a digital model of an individual component, such as a tooth or gum tissue, in a patient's dentition. The computer receives a data set that forms a three-dimensional (3D) representation of the patient's dentition, applies a test to the data set to identify data elements that represent portions of the individual component, and creates a digital model of the individual component based upon the identified data elements. Many implementations require the computer to identify data elements representing a 2D cross-section of the dentition lying in a 2D plane that is roughly parallel to or roughly perpendicular to the dentition's occlusal plane. The computer analyzes the 2D cross-section to identify dentition features that represent boundaries between individual dentition components.

    Abstract: A computer obtains a digital model of a patient's dentition, including a dental model representing the patient's teeth at a set of initial positions and a gingival model representing gum tissue surrounding the teeth. The computer then derives from the digital model an expected deformation of the gum tissue as the teeth move from the initial positions to another set of positions.

    Abstract: A programmed computer is used to create a digital model of an individual component of a patient's dentition. The computer obtains a 3D digital mode of the patient's dentition, identifies points in the dentition model that lie on an inter-proximal margin between adjacent teeth in the patient's dentition, and uses the identified points to create a cutting surface that separates portions of the dentition model representing the adjacent teeth.

    Abstract: Systems and methods for fabricating a dental template to position an object on a patient's tooth to move the tooth from an initial position to a target position are disclosed. The system digitizes a model of the patient's tooth at the initial position; places an object on the tooth model at the target position; determines the position of the object at the initial position; and fabricates the dental template to locate the object on the patient's tooth.
