摘要： Modeling pontics at successive treatment stages includes: (1) calculating space measurements between first and second teeth by getting first and second tooth transformations at a treatment stage i; (2) applying the first and second tooth transformations to get positions of the first and second teeth at the stage i; (3) calculating a direction vector of the space measurements at the stage i; (4) calculating a reference plane using the direction vector as a normal; (5) determining whether the space is available for a pontic by measuring the distance from the closest point on each of the first and second teeth to the reference plane; (6) generating an original pontic geometry for a first treatment stage; and (7) generating pontic geometries at each successive stage by calculating deformation parameters based on the original pontic geometry and size characteristics of the space and of the first and second teeth at each stage.

摘要： 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： 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.
