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.
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.

The invention relates to a manufactured orthodontic archwire, made from a wire which, in a relaxed state, has a generally arcuate configuration corresponding to an archform for a particular patient. The manufactured orthodontic archwire comprises a series of straight segments for placement into a slot of a bracket bonded to a tooth of the patient, which are connected to each other by curved segments, comprising bends and/or twists, each forming a precision geometrical relationship between adjacent straight segments of the wire. At least one pair of adjacent straight slot segments are connected to each other by a curved segment comprising a combination of a bend and a twist, which forms a precision geometrical relationship between the adjacent straight segments in the wire. The invention also extends to a robotic wire bending system comprising a bending robot and a robot controller, the bending robot producing a multitude of customized archwires as described above for a multitude of patients.
