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.

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: An intelligent restoration proposal including using an input resource to segment a 3D jaw model to obtain a segmented missing or unhealthy teeth and omitting the segmented missing or unhealthy teeth from the 3D jaw model to obtain a modified 3D jaw model. The modified 3D jaw model is used as input to a restoration proposal module to propose an output restoration. The restoration proposal module is operated as a machine learning engine. The restoration proposal is trained using a database that includes healthy teeth.

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: A parameter recommendation module is used to propose a recommendation for dental restoration material parameters. The recommendation takes into consideration final tooth color influencing factors such as underlying tooth stump color and color of restoration fastening material such that at least one output restoration characteristic value needed to achieve a final user-specific tooth color for at least one tooth layer of the restoration is proposed.

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.
