Abstract: A method and system to automate an administration and restoration generation process that includes forming a spline along a jaw, proposing potential interdental gaps, weighting the potential interdental gaps to obtain one or more delimiters, automatically proposing tooth number probabilities, and computing a best fit tooth number distribution to generate a patient specific restoration.

Abstract: Method for visualizing a tooth situation. The invention relates to a method for visualizing a tooth situation, wherein an image of the face of a patient is recorded and stored as a facial data record (1), feature points (3) within the facial data record (1) are automatically recognized by means of a facial recognition method, a mouth area (4) located between the lips is recognized automatically on the basis of the feature points (3), a position of the face in the facial data record (1) and a three-dimensional direction (5) of an orientation of the face in the facial data record (1) is automatically recognized on the basis of the feature points (3), a virtual tooth data record (2) of the tooth situation is oriented according to the three-dimensional direction (5) of the orientation of the face and is positioned according to the position of the face with respect to the facial data record (1), the mouth area within the facial data record (1) is partially overlaid and/or overlaid and/or replaced by the tooth data record (2), and the result is displayed as a visualization data record.

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 may be for example, a 3D model of a tooth or teeth or dental anatomy.

Abstract: The invention relates to a method for constructing a dental component (I) using a graphic representation of a dental condition. A 3D volume model of the dental condition is thus already correlated with a 3D surface model of the dental condition, wherein the graphic representation of the 3D volume model is restricted to relevant regions by delimitation using the 3D surface model or using a section thereof, wherein the remaining regions of the 3D volume model are hidden.

Abstract: Using a configuration recommendation module, a recommendation for configuring a dental manufacturing system is proposed. The recommendation takes into consideration user-specific information such as preferred dental practitioner tools, preferred restoration esthetics and dynamic and static inputs automatically retrieved by a CAD/CAM (computer-aided design/computer-aided manufacturing) resource.

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.
