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: A method for designing a dental component, specifically a restoration, a bite guard or an impression tray, comprising the steps of measuring a dental situation; generating a 3D model of the dental situation; applying an artificial neural network for machine learning (convolutional neural network; CNN) to the 3D model of the dental situation and/or an initial 3D model of the dental component, and automatically generating a fully designed 3D model of the dental component, specifically the restoration, the bite guard or the impression tray.

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: In a method of planning a restorative dental treatment for a patient, at least two dental restorations are digitally constructed (20). In the process, an optimum specification (40) for the insertion of the restorations into the mouth of the patient is calculated (30), wherein the optimum specification for the insertion of the restorations comprises an optimum sequence of the restorations to be inserted; if applicable, including optimum insertion paths for the restorations to be inserted.
