摘要： Interactive, computer based orthodontist treatment planning, appliance design and appliance manufacturing is described. A scanner is described which acquires images of the dentition which are converted to three-dimensional frames of data. The data from the several frames are registered to each other to provide a complete three-dimensional virtual model of the dentition. Individual tooth objects are obtained from the virtual model. A computer-interactive software program provides for treatment planning, diagnosis and appliance from the virtual tooth models. A desired occlusion for the patient is obtained from the treatment planning software. The virtual model of the desired occlusion and the virtual model of the original dentition provide a base of information for custom manufacture of an orthodontic appliance. A variety of possible appliance and appliance manufacturing systems are contemplated, including customized archwires and customized devices for placement of off-the shelf brackets on the archwires, and removable orthodontic appliances.

摘要： Method and system for designing and making one or more artificial nails customized to fit one or more real nails of a client are disclosed. Additionally, the invention enables customization or selection of decorative patterns for the artificial nail. The process begins with scanning one or more nails of the client with a scanner. The scanned image is then converted into a virtual three-dimensional surface model for each real nail. The virtual three-dimensional model of each nail is displayed on a monitor of a workstation. The user, e.g. a beautician at a beauty saloon, using the workstation and in consultation with the client, designs a customized artificial nail using the virtual three-dimensional model of the real nail. At the user command, the customized design of the artificial nail is then sent to a numerically controlled (NC) or a similar machine, where the artificial nail is made in accordance with the custom design. The artificial nail may be made from acrylic materials or other suitable materials.

摘要： An orthodontic workstation stores a library of virtual three-dimensional brackets in a memory. Each of the virtual brackets has a unique three-dimensional configuration and prescription. Typically, the library of bracket comprises a library of commercially available, off-the-shelf brackets. The workstation further includes an interactive treatment planning program that permits a user to move teeth from a virtual model of the dentition to a proposed set-up. In one possible embodiment, the treatment planning program provides the ability to display a virtual bracket placed on a virtual tooth and change the prescription or configuration of the virtual bracket. The treatment program automatically compares the modified prescription with the prescription information of the virtual brackets in the library and selects a bracket from the library that most closely matches the virtual bracket displayed on the tooth. Thus, the user does not have to use customized brackets. Any deviation in tooth position resulting from a discrepancy between the off-the-shelf bracket and the user-defined bracket can be corrected for by changing the position of the bracket on the tooth or by changing the shape of the archwire.

摘要： A method and apparatus for arch wire receptacle (e.g., brackets, bands, headgear tubes, etc.) optimization includes processing that begins by obtaining a digital model of an orthodontic structure of an orthodontic patient. The processing then continues by retrieving a digital model of an initial arch wire receptacle that was selected from a plurality of digital models of arch wire receptacles. The processing then continues by digitally placing the digital model of the initial arch wire receptacle on a given tooth of the digital model of the orthodontic structure to provide a digital arch wire receptacle placement. The process then proceeds by retrieving a digital model of an arch wire. For the given tooth, the processing continues by digitally modeling a force system on the tooth based on the digital model of the initial arch wire receptacle, the digital arch wire receptacle placement, and the digital model of the arch wire. Having done this, when the force system is not optimal, the force system is modified to achieve an optimal forced system.

摘要： Templates are disclosed that permit an orthodontist to accurately place appliances such as bracket shims or brackets on a tooth or teeth at a desired position. The templates can be used for accurately locating the position of other dental or orthodontic procedures, such as varnishing, tooth etching and root canals. The templates are made from a flexible sheet of material adapted to be adhered directly to the surface of the tooth or teeth. The sheet of material is formed with the outline of the tooth or teeth or in the shape of the tooth to allow the template to be posited in a proper, reference position. The sheet of material is also formed with one or more marks indicating the location of the bracket on the tooth, for example one mark indicting the bracket base location and other marks indicating the orientation of the base and bracket slot. The mark indicating the bracket base is punched out or otherwise removed from the sheet to provide a void in the template, enabling the user to directly bond the bracket to the tooth at the location of the void.
