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.

Systems and methods for automatic detection of dental features, such as cusps, ridges, and grooves, are disclosed. In accordance with an exemplary embodiment, a computer-implemented system and method for automatic detection of dental features for an occlusal surface of a patient's tooth comprises receiving three dimensional data for the tooth's occlusal surface, projecting the three dimensional data into a two dimensional plane, forming a height map from the projected three dimensional data, and detecting a set of points from the height map.

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.

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. 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. 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.
