The invention provides a digital dentistry system that utilizes a haptic interface and features a computer-based design application configured to allow the intuitive construction of irregular, amorphous three-dimensional structures typically seen in dental restorations, utilizing, where appropriate, the design skills of a user. In certain embodiments, the system provides a comprehensive digital solution for dental labs in the business of creating dental restorations such as partial frameworks, crowns, copings, bridge frameworks, implants and the like, with a sense of touch provided by a haptic interface device.

Haptically enabled dental modeling system

The invention provides a system for modeling three-dimensional objects using hybrid geometric/volumetric representation, wherein sharp edges are created by a geometric representation that is connected to the volumetric representation. The system creates, maintains, and updates the hybrid representation according to user input. The system also provides for conversion of the hybrid representation into either a wholly geometric representation or a wholly volumetric representation, as may be needed for output to a given device, such as a display device, a printer, and/or a fabricating device.
