Disclosed in a method, a user interface and a system for use in determining shade of a patient's tooth, wherein a digital 3D representation including shape data and texture data for the tooth is obtained. A tooth shade value for at least one point on the tooth is determined based on the texture data of the corresponding point of the digital 3D representation and on known texture values of one or more reference tooth shade values.

Detecting tooth shade

Disclosed is a computer-implemented method of designing a number of dental restorations for a patient, wherein the method includes: selecting a composed set of teeth including a number of teeth, where the number of teeth are arranged spatially relative to each other forming a high aesthetic composition; applying the composed set of teeth to a virtual three dimensional representation of the patient's present oral situation to obtain an initial set of teeth; optionally modifying one or more parameters of one or more of the teeth in the initial set of teeth to obtain a finalized set of teeth.

Method of composing and designing a set of teeth

3D modeling of an object using textural features. Disclosed is a method and a system for 3D modeling of a 3D object adapted to be inserted in or worn by a patient. The 3D modeling applies information of one or more features from an acquired 2D digital representation including textural data of the location where the 3D object is adapted to be arranged.

3D modeling of a dental restoration using textural features

A method for visualizing a 3D dental restoration on a 2D image of the mouth of a patient includes obtaining a 3D dental model of at least a part of the patient's oral cavity, designing the 3D dental restoration, obtaining the 2D image of the mouth of the patient, estimating a virtual camera including at least one virtual camera property corresponding to at least one physical camera property of the physical camera used to obtain the 2D image, viewing the 3D dental restoration using the virtual camera, determining the visible area of the 3D dental restoration, which is not overlapped by surrounding anatomic features when viewed with the virtual camera, imaging the visible area of the 3D dental restoration with the 2D image. This advantageously provides an image which with high accuracy gives the dentist and the patient a visual presentation of the final result of a dental treatment.

Tools in a system for the design of customized three-dimensional models of dental restorations for subsequent manufacturing. Dental restorations such as implant abutments, copings, crowns, wax-ups, bridge frameworks. Moreover, a computer-readable medium for implementing such a system on a computer. A system for designing at least one dental restoration, said system including: a display, means for acquiring and displaying a three dimensional dental restoration model of the dental restoration, and means for displaying a plurality of control points, each of the control points corresponding to a respective location on the dental restoration model, and each of said control points enabling manual customization of the dental restoration model.

The present invention provides a method for computer-controlled creation of non-occluding earpieces with tube bore. The non-occluding earpieces are created based on a three-dimensional computer model of at least part of the outer ear and at least part of the auditory canal. The said model is created by a laser scanner, in the ear scanner or by other means. The said three-dimensional computer model is virtually modified to create the non-occluding earpieces and the tube bore. Finally the physical non-occluding earpieces are manufactured using rapid prototyping equipment.

A method, a user interface and a system for use in determining shade of a patient's tooth, wherein a digital 3D representation includes shape data and texture data for the tooth is obtained. A tooth shade value for at least one point on the tooth is determined based on the texture data of the corresponding point of the digital 3D representation and on known texture values of one or more reference tooth shade values.

A method for planning, visualizing, and/or optimizing dental restoration on the pre-prepared teeth of a patient. The method includes obtaining 3D digital models of the pre-prepared teeth and the prepared teeth, and aligning these 3D models. A CAD model of a dental restoration for the prepared teeth is designed based on the 3D digital model of the pre-prepared teeth.

System and method for effective planning, visualization, and optimization of dental restorations

A method for visualizing a 3D dental restoration on a 2D image of the mouth of a patient, the method including obtaining a 3D dental model of at least a part of the patient's oral cavity, designing the 3D dental restoration, obtaining the 2D image of the mouth of the patient, estimating a virtual camera comprising at least one virtual camera property corresponding to at least one physical camera property of the physical camera used to obtain the 2D image, viewing the 3D dental restoration using the virtual camera, determining the visible area of the 3D dental restoration, which is not overlapped by surrounding anatomic features when viewed with the virtual camera, imaging the visible area of the 3D dental restoration with the 2D image. This provides an image which with high accuracy gives the dentist and the patient a visual presentation of the final result of a dental treatment.

A system and a computer-implemented method of designing and/or manufacturing a post and core to match a bore of a tooth, said method including the steps of: a) obtaining at least one impression of a set of teeth comprising a bore; b) scanning the impression of the set of teeth comprising the bore; c) providing a three-dimensional scan representation of the impression comprising the bore; d) transforming the three-dimensional scan representation to a three-dimensional positive working model of the set of teeth and the bore; and e) designing a post and core model from the positive working model of the bore. In particular, CAD/CAM design and/or manufacture of post and core.
