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.
摘要翻译：提供了一种用于在牙齿和相关解剖结构的虚拟三维模型中自动分离牙冠和牙龈组织的方法。该方法参照平面定向模型，并自动确定模型的局部最大值和由局部最大值限定的区域。该方法自动确定模型中局部最大值之间的鞍点，鞍点对应于牙齿之间的边界。该方法进一步沿着牙弓形式定位鞍点。对于每颗牙齿，该方法自动识别模型表面上沿着模型表面连接鞍点的线或路径，该路径标记模型中牙齿与牙龈组织之间以及相邻牙齿之间的过渡。这些线所包围的区域对应于牙冠; 模型的其余部分构成牙龈组织。

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.
摘要翻译：单个表面表示是从点云创建的。点云中的每个点都被分配三维空间坐标。点云被存储在计算机的存储器中。为在云点上运行的计算机提供机器可执行指令。指令从点云构造一个初始三角形。指令构造了形成表示对象的单个连续表面的多个相邻三角形。三角形包括具有三个顶点的平面表面。相邻三角形的顶点包括形成初始三角形的三个点和多个其他点。除了最初的两点之外，形成三角形的点各自被计算为满足选择标准的点云中的一组附近点的加权平均值。所得到的顶点也必须满足一个或多个选择标准。最终加权平均表面表示需要比初始点云要少得多的数据来表示物体表面。

摘要： An integrated system is described in which digital image data of a patient, obtained from a variety of image sources, including CT scanner, X-Ray, 2D or 3D scanners and color photographs' , are combined into a common coordinate system to create a virtual three-dimensional patient model. Software tools are provided for manipulating the virtual patient model to simulation changes in position or orientation of craniofacial structures (e.g., jaw or teeth) and simulate their affect on the appearance of the patient. The simulation (which may be pure simulations or may be so-called "morphing" type simulations) enables a comprehensive approach to planning treatment for the patient. In one embodiment, the treatment may encompass orthodontic treatment. Similarly, surgical treatment plans can be created. Data is extracted from the virtual patient model or simulations thereof for purposes of manufacture of customized therapeutic devices for any component of the craniofacial structures, e.g., orthodontic appliances.

摘要： A method and workstation for orthodontic treatment planning of a patient. The workstation is based on a computing platform having a graphical user interface, a processor and a computer storage medium containing digitized records pertaining to a patient including image data (3D image data and/or 2D image data). The workstation further includes a set of software instructions providing graphical user interface tools which the user marks a midline and an aesthetic occlusal plane in a two- or threedimensional virtual model of the patient, marks an occlusal plane in the virtual model; selects a reference tooth in the virtual model; aligns virtual teeth in the virtual model in a proposed arrangement to treat the patient; manages space between the virtual teeth in the proposed arrangement; and repeats one or more of these steps in an iterative fashion to make any further adjustments in the proposed arrangement. When the adjustments are complete, the user selects or identifies a finalized proposed treatment plan for treating the patient.

摘要： An interactive, unified workstation is described that unifies in a single system multitude of functions pertaining to a practitioners practice that would otherwise require disjointed, more expensive, and less efficient individual workstations dedicated to a specific, limited task or a sub-set of tasks. The invention is directed towards benchmarking for a practitioner's business practice, and for clinical aspects of treatment planning; and integrating overall patient care planning functions. The unified workstation further facilitates access to archived database resources and facilitates both knowledge base services to practitioners and also hybrid treatment planning, wherein different types of appliance systems (fixed, such as brackets and wires, or removable, such as aligning shells) may be used during the course of treatment.
