摘要： An apparatus and method are described for forming 2D views of a structure from 3D point data. In the present invention, a plane is specified and triangulated meshes are intersected with the plane to form a group of polylines. The significant features of each polyline are then extracted, and the features are then connected to form intersection polylines that closely approximate the intersection polylines that would be generated by intersecting the real 3D structure with the specified plane. The final 2D view consists of the connected features extracted from the polylines.

摘要： A system and method for modeling of complete tooth, including root and crown, of a patient to facilitate orthodontic treatment are provided, wherein a generic tooth modeling is combined with a tooth crown modeling for a patient to yield a complete tooth modeling. In accordance with an exemplary embodiment, a generic tooth three-dimensional model for a particular tooth is morphed with a three-dimensional model of a patient's crown for the corresponding tooth to yield a complete three-dimensional model for that tooth. Such modeling techniques can be conducted with one or more computer-based systems, such as systems configured for storing patient data and generic tooth data, morphing such data and/or facilitating additional orthodontic treatment applications, through the use of one or more algorithms. Further adjustment of the complete tooth model for the tooth can also be provided through additional patient information, such as X-ray imaging, to address variations in root shape between a generic root and an actual root shape for a patient.

摘要： In accordance with various aspects of the present invention, system and method for modeling and application of interproximal reduction (IPR) of teeth to facilitate orthodontic treatment is provided. In accordance with an exemplary embodiment, a system and method for modeling and application of IPR are configured within a treatment methodology that initially determines whether stripping is needed for two neighboring teeth. If stripping is necessary, the exemplary method for modeling and application of IPR is conducted. In an exemplary embodiment, a stripping plane or other surface is constructed to determine the amount and region of stripping for two neighboring teeth, in other words, the volume to be removed between two neighboring teeth. After stripping of the tooth, the tooth geometry can be reconstructed to enable application of the IPR tooth model, such as enabling the clinician to utilize the IPR tooth model for teeth movement planning.

摘要： The present disclosure provides computing device implemented methods, computing device readable media, and systems for adjustment of tooth position in a virtual dental model. Virtual dental modeling can include detecting space and/or collision between posterior teeth of an upper jaw and posterior teeth of a lower jaw in a virtual dental model that has been set in a preliminary target position. An energy function can be defined including the space and/or collision, tooth root movement, and align points. Weights can be assigned for each variable in the energy function. A position of the posterior teeth of the upper jaw and the posterior teeth of the lower jaw can be adjusted in six degrees of freedom to minimize the energy function. The detection, definition, assignment, and adjustment can be repeated until the energy function converges. The weights can be adjusted to reduce the space and/or collision.
