    摘要： A method and apparatus are disclosed enabling an orthodontist or a user to create an integrated three dimensional digital model of dentition and surrounding anatomy of an orthodontic patient from a three-dimensional digital model obtained using a scanner with a three-dimensional digital model obtained using a Cone Beam Computed Tomography (CBCT) or Magnetic Resonance Tomography (MRT) imaging devices. The digital data obtained from scanning as well as from CBCT imaging are downloaded into a computer workstation, and registered together in order to create a comprehensive 3-D model of the patient's teeth with roots, bones and soft tissues. The invention provides substantial improvement over the traditional two dimensional imaging modalities such as x-rays, photographs, cephalometric tracing for diagnosis and treatment planning.

    摘要： A single surface representation is created from a cloud of points. Each point in the cloud of points is assigned three-dimensional spatial coordinates. The cloud of points is stored in a memory of a computer. Machine-executable instructions are provided for the computer that operate on the cloud of points. The instructions construct an initial triangle from the cloud of points. The instructions construct a multitude of adjacent triangles forming a single continuous surface representing the object. The triangles comprise planar surfaces having three vertices. The vertices of the adjacent triangles comprise the three points forming the initial triangle and a multitude of other points. Except for the initial two points, the points forming the triangles are each computed as a weighted average of a set of nearby points in the cloud of points that satisfy selection criteria. The resulting vertex also has to satisfy one or more selection criteria. The final weighted average surface representation requires much less data to represent the object surface than the initial point cloud.

    摘要： A method is provided for automatically separating tooth crowns and gingival tissue in a virtual three-dimensional model of teeth and associated anatomical structures. The method orients the model with reference to a plane and automatically determines local maxima of the model and areas bounded by the local maxima. The method automatically determines saddle points between the local maxima in the model, the saddle points corresponding to boundaries between teeth. The method further positions the saddle points along a dental arch form. For each tooth, the method automatically identifies a line or path along the surface of the model linking the saddle points to each other, the path marking a transition between teeth and gingival tissue and between adjacent teeth in the model. The areas bounded by the lines correspond to the tooth crowns; the remainder of the model constitutes the gingival tissue.
