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： A robotic bending apparatus for bending archwires and other types of elongate, bendable medical devices into a desired configuration includes a first gripping tool and a moveable gripping tool. The first gripping tool can be either fixed with respect to a base or table for the robot or positioned at the end of robot am. The moveable gripping tool is mounted to the end of a moveable robot arm having a proximal portion also mounted to the base. The robot preferably comprises a six axis bending robot, in which the distal end of the moveable arm can move relative to the fixed gripping tool about three translational axes and three rotational axes. The gripping tools preferably incorporate force sensors which are used to determine overbends needed to get the desired final shape of the archwire. The robot may also include a resistive heating system in which current flows through the wire while the wire is held in a bent condition to heat the wire and thereby retain the bent shape of the wire. A magazine for holding a plurality of straight archwires needing to be bent and a conveyor system for receiving the wires after the bending process is complete are also described. The robot bending system is able to form archwires with any required second and third order bends quickly and with high precision. As such, it is highly suitable for use in a precision appliance-manufacturing center manufacturing a large number of archwires (or other medical devices or appliances) for a distributed base of clinics.

摘要： Occlusal contact between upper and lower virtual three-dimensional teeth of a patient when the upper and lower arches are in an occlused condition are determined and displayed to the user on a user interface of a general purpose computing device. Various techniques for determining occlusal contacts are described. The areas where occlusal contact occurs is displayed on the user interface in a readily perceptible manner, such as by showing the occlusal contacts in green. If the proposed set-up would result in a interpenetration of teeth in opposing arches, such locations of interpenetration are illustrated in a contrasting color or shading (e.g., red). The ability to calculate distances and display occlusal contacts in a proposed set-up assists the user in planning treatment for the patient. The process can be extended to interproximal contact detection as well. The concepts also apply to dental prosthetics, such as crowns, fillings and dentures.

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.

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： A method and apparatus for generating a patient treatment plan includes processing that begins by providing a list of health care services to a patient and/or care provider. The processing continues by prompting for input of digital information regarding the patient when health care services applicable to addressing the patient's treatment needs have been concurrently selected. The processing continues by determining whether a sufficient amount of digital information has been received. If so, the processing continues by simulating treatment of a patient based on the digital information, a treatment objective, and normalized patient data. The processing then continues by generating the patient treatment plan in accordance with the simulating of the treatment when the simulated treatment results have been acknowledged.

摘要： A method is provided for scanning the surface of an object in which moisture such as saliva or water is present on the surface. The method includes the step of applying a saliva and water-resistant composition to the surface, wherein the composition is characterized in that it does not readily wash off the surface after application of the composition to the surface in the presence of saliva or water. The composition forms an opaque film on the surface. The method further includes the step of scanning the surface having the film with a scanner. Several formulations for the composition are disclosed. One includes a liquid alcohol base, such as dehydrated ethyl alcohol, a reflective pigment, and a binder for promoting good adhesion of the formulation to the surface of the object being scanned. A suitable binder for scanning teeth and other oral structures is a denture adhesive such as an off-the-shelf denture adhesive, in powder form, that is mixed with the pigment and the alcohol base. Other suitable compositions can be derived by persons skilled in the art from the teachings disclosed herein.
