    摘要: 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.

    摘要: A positive mold for use in creating an orthodontic appliance is produced by obtaining a digital dentition model, such as a 3D geometric surface model or a 3D volumetric image model, that defines the shape of an orthodontic appliance and then altering the digital dentition model to remove a portion that does not affect the shape of the orthodontic appliance. The altered digital dentition model then is used to construct a positive mold for the orthodontic appliance. Processing circuitry, such as a programmed computer, is used to obtain and alter the digital dentition model. A rapid prototyping device, such as a stereolithography machine, is commonly used to construct the positive mold.
