    摘要： An interactive, software-based treatment planning method to correct a malocclusion is described. The method can be performed on an orthodontic workstation in a clinic or at a remote location such as a lab or precision appliance manufacturing center. The workstation stores a virtual three-dimensional model of the dentition of a patient and patient records. The virtual model is manipulated by the user to define a target situation for the patient, including a target archform and individual tooth positions in the archform. Parameters for an orthodontic appliance, such as the location of orthodontic brackets and resulting shape of an orthodontic archwire, are obtained from the simulation of tooth movement to the target situation and the placement position of virtual brackets. The treatment planning can also be executed remotely by a precision appliance service center having access to the virtual model of the dentition. In the latter situation, the proposed treatment plan is sent to the clinic for review, and modification or approval by the orthodontist. The method is suitable for other orthodontic appliance systems, including removable appliances such as transparent aligning trays.

    摘要： A method for monitoring tooth wear and a method for monitoring tooth wear and gingival recession and erosion by comparing three-dimensional virtual models at different times are described, as well as occlusal contact between upper and lower virtual three-dimensional teeth of a patient when the upper and lower arches are in an occluded 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： A method is described for taking a three-dimensional virtual model of the dentition and associated anatomical structures of a patient and isolating individual teeth from the rest of the anatomical structure, e.g. gums, to thereby produce individual, virtual three-dimensional tooth objects. The individual tooth objects can be displayed on the display of an orthodontic workstation and moved independently from each other, and thereby form the basis of planning treatment for the patient. The individual, virtual three-dimensional tooth objects are created by comparing the virtual model of the dentition to virtual, three-dimensional template teeth that are stored in memory in a process described in detail herein. The template teeth can include roots as well as crowns. The template teeth can be stored objects acquired from some external source or alternatively developed from a database of patient scans. Virtual three-dimensional brackets are also stored in the memory of the workstation. The virtual brackets can be placed on the virtual teeth and moved relative to the teeth as needed in a preliminary step in treatment planning.
