Abstract

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.
