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 generic tooth modeling is combined with tooth crown modeling for a patient to yield complete tooth modeling. A generic tooth 3D model for a particular tooth is morphed with a 3D model of a patient's crown for the corresponding tooth to yield a complete 3D model for that tooth. Modeling techniques can be conducted with 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. Adjustment of the complete tooth model for the tooth can 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.

System and method for automatic construction of orthodontic reference objects, such as the occlusal plane, arch form, and the local occlusal plane for a patient's teeth are disclosed. In accordance with an exemplary embodiment, a computer-implemented system and method for automatic construction of orthodontic reference objects comprises receiving three dimensional data for the teeth, setting an initial direction for a normal of the occlusal plane, determining tips for selected teeth, calculating a plane that matches the determined tip, and determining a new normal for the calculated plane.

The present invention relates to systems and methods for detecting deviations from an orthodontic treatment plan. One method includes receiving a tracking model, performing a matching step between individual teeth in a plan model and the tracking model, comparing the tracking model with the plan model, and detecting one or more positional differences.

In accordance with various aspects of the present invention, systems and methods for representation, modeling and/or application of pontic geometry of teeth to facilitate orthodontic treatment are provided. Such systems and methods for representation, modeling and application of pontic geometry of teeth can automatically facilitate a changeable and stage-dependent pontic geometry that provides various advantages over conventional methods for providing pontics. In accordance with an exemplary embodiment, a system and method for representation, modeling and/or application of pontic geometry automatically detects for the potential location for one or more pontics, i.e., for spaces between the teeth of a patient. Once a desired location for a pontic is automatically determined, an original pontic geometry is automatically generated. Thereafter, stage dependent pontic geometries are automatically generated and positioned during the stages of treatment if pontic is desirable.
摘要:
System and method for automatic construction of the tooth's axes in terms of three orthogonal unit vectors are disclosed. Three dimensional data for a tooth is used to automatically construct the tooth's axes. System and methods for automatic construction of the axes for different types of teeth such as incisors, canines, premolars, and molars are disclosed.

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.

The present disclosure includes computing device related, systems, and methods for identifying force placed on a tooth are described herein. One method includes receiving initial orthodontic data (IOD) including teeth data; creating a virtual set of teeth from the IOD; receiving dental appliance information including at least one of dental appliance material properties and characteristics; virtually placing a dental appliance, formed from the dental appliance information, onto the virtual set of teeth; and determining one or more forces applied to the teeth based on information from the IOD and dental appliance information.
