摘要： 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.

摘要： The invention provides systems for integrated haptic design and fabrication of dental restorations that provide significant advantages over traditional practice and existing computer-based systems. The systems feature technical advances that result in significantly more streamlined, versatile, and efficient design and fabrication of dental restorations. Among these technical advances are the introduction of voxel-based models; the use of a combination of geometric representations such as voxels and NURBS representations; the automatic identification of an initial preparation (prep) line and an initial path of insertion; the ability of a user to intuitively, haptically adjust the initial prep line and/or the initial path of insertion; the automatic identification of occlusions and draft angle conflicts (e.g., undercuts); the haptic simulation and/or marking of occlusions and draft angle conflicts; and coordination between design output and rapid prototyping/milling and/or investment casting.
