Abstract: A method and system for manipulating a 3D model during treatment planning and automatically adjusting the 3D model based on a localized area of the 3D model proximate to a location of said manipulation. The 3D model is automatically adjusted during the course of treatment planning such that a user has an unobstructed view of the surface. The 3D model may be for example, a 3D model of a tooth or teeth or dental anatomy.

Abstract: The invention relates to a method for constructing tooth surfaces of a dental prosthesis and for producing dental restorations, starting from a 3D data record of an upper mandible layout and a 3D data record of a lower mandible layout, each layout comprising a number of teeth arranged in each mandibular arch and the teeth of the upper mandible layout and the teeth of the lower mandible layout at intercuspation making contact with each other at multiple contact points. The contact surfaces are selected by approximation. Relevant surface pairs lying opposite one another are identified and are incorporated by an optimization algorithm into local minimum distances, taking into consideration surfaces that can slide past one another. This allows the desired contact points to be produced. Surfaces that have not been selected are not considered in the production of the points of contact.

The first region is selected to comprise at least two implants and/or preparations. Subsequently, object regions surrounding the implants and/or the preparations are established, and, while using a second measuring method, the established object regions are detected, and second measurement data are generated. The second measuring method is more precise than the first measuring method.
