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: Manufacturing a dental part with volumetric units that vary in translucency, shading and/or color. A beam translation module of a 3D printing system is used to translate an input pattern into an output for controlling a spatial structuring of light for 3D printing an object from a resin material that is sensitive to light intensity, light color or light exposure time.

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: A method, system and computer readable storage media for defects in images during three-dimensional measurement of teeth. An operator may use a dental camera to scan teeth and a trained deep neural network may automatically detect portions of the input images having defects and generate output information regarding those defects for corrective measures to be taken.

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: A method for designing a drilling template, wherein a dental situation is measured by means of a 3D surface measuring device and a 3D surface model of the dental situation is produced and/or measured by means of an X-ray device or an MRI device, wherein the dental situation is measured and a volume model of the dental situation is produced, the method comprising the steps of: applying an artificial neural network for machine learning (convolutional neural network; CNN) to the 3D surface model of the dental situation and/or the volume model of the dental situation and/or to an initial 3D model of the drilling template; and automatically producing a ready made 3D model of the drilling template.

Abstract: invention further relates to a method for producing a dental prosthesis. In this method the dental prosthesis block is provided and the dental prosthesis is produced by removing material from the dental prosthesis forming block by means of a CAD/CAM method, such that the pin forms part of the finished dental prosthesis.
