摘要:
An apparatus and method for bending or shaping orthodontic archwires or other medical devices into a complex, patient individual shape is described. The apparatus comprises of two moveable, compact, manipulators with, in total, at least three revolute joints defining three rotation axes and at least three prismatic joints defining at least three translation axes. Gripping tools are provided on the manipulators. The two manipulators are arranged to allow a relative movement in six degrees of freedom. A reduced complexity embodiment is also described having only one or two revolute joints.
摘要:
Method and apparatus for registering an object of known predetermined geometry to scanned three dimensional data such that the object's location may be verified. Such a known object may comprise a less than ideal three-dimensional (3-D) digital object such as a tooth, a dental appliance (e.g., as a tooth bracket model) or other like object, including portions thereof. Knowledge of such an object's location is generally helpful in planning orthodontic treatment, particularly where the location of the object needs to be determined or confirmed or where incomplete or poor scan data is obtained. Aspects of the present invention provide methods of effectively verifying dental appliance location and displaying appliance locations using a computer and three-dimensional models of teeth.
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 colour 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 effect 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 apparatus for generating an orthodontic template that assists in the placement of an orthodontic apparatus includes processing that begins by obtaining a digital model (34) of an orthodontic structure of a patient. The processing continues by obtaining a selection of one of a plurality of orthodontic apparatuses for the orthodontic structure to produce a selected orthodontic apparatus. A digital model of placement of the selected apparatus is obtained, then a digital image of a tooth mounting apparatus (32) is retrieved. An orthodontic template is generated for holding a physical embodiment of the tooth mounting apparatus based on the digital image of the tooth mounting apparatus, the digital model of the placement, and at least a portion of the digital model of the orthodontic structure.

A machine vision system (1102, 1104) for an apparatus (108) for bending or shaping orthodontic archwires (122) or other medical devices into a complex, patient individual shape is described. The apparatus comprises two moveable, compact, manipulators (112,114) with, in total, at least three revolute joints defining three rotation axes and at least three prismatic joints defining at least three translation axes. Gripping tools (116,118) are provided on the manipulators. The two manipulators are arranged to allow a relative movement in six degrees of freedom. The machine vision system is configured to monitor movements of the manipulators and a shape of said archwire before and after bending.
