摘要： A method and system are disclosed for finding virtual tooth features on virtual three-dimensional models of the teeth of patients. The tooth features comprise marginal ridges, cusp tips, contact points, central groove and buccal groove. Tooth axes system plays a key role in identifying the tooth features. An iterative method is disclosed for improving the accuracy of the tooth axes system. A virtual three-dimension model preferably obtained by scanning the dentition of a patient forms the basis for determining the tooth features. Tooth features are derived for all categories of teeth including molars, premolars, canines and front teeth. Tooth features are very helpful and used in planning orthodontic treatment. The tooth features are determined automatically using the computerized techniques; and can be manually adjusted when necessary.

摘要： A method and apparatus are disclosed enabling an orthodontist or a user to create an unified three dimensional virtual craniofacial and dentition model of actual, as-is static and functional anatomy of a patient, from data representing facial bone structure; upper jaw and lower jaw; facial soft tissue; teeth including crowns and roots; information of the position of the roots relative to each other; and relative to the facial bone structure of the patient; obtained by scanning as-is anatomy of craniofacial and dentition structures of the patient with a volume scanning device; and data representing three dimensional virtual models of the patient's upper and lower gingiva, obtained from scanning the patient's upper and lower gingiva either (a) with a volume scanning device, or (a) with a surface scanning device. Such craniofacial and dentition models of the patient can be used in optimally planning treatment of a patient.

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 and system for orthodontic treatment planning, evaluation and quality measurement is provided comprising a workstation having computing platform, a graphical user interface, a processor and a computer storage medium containing digitized records pertaining to a patient. The digitized records include image and other types of data. The computer storage medium further includes a set of software instructions providing graphical user interface tools for providing a user with access to the digitized records for planning orthodontic treatment of a patient. Also provided are reference databases for aiding in the decision process during treatment selection, treatment planning and treatment delivery and progress monitoring and evaluation. Also provided are parameter or criteria measurement techniques and generally acceptable thresholds, which can be updated through learning process and through acquisition of patient data. Once the treatment is planned, the virtual dentition model of the patient in the proposed treatment set-up or the target state is evaluated using several virtual model evaluation features and criteria.

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.
