Abstract: 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.

Abstract: A method of aligning two 3D digital representations of at least a part of each of the upper and lower jaw of a patient, the method including segmenting the 3D digital representations to determine the shape and position of each of the patient's teeth in each of the 3D digital representations; and using a set of known anatomical concepts to constrain the fit of the two 3D digital representations to get a preliminary fit.

Abstract: 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.

Abstract: A method for placing and using design guides in a virtual environment for use in dental treatment includes steps of obtaining a 3D representation of a dental setup a patient, obtaining a 2D image of at least a part of the face of the patient, aligning the 2D image and the 3D representation, generating at least one design guide based on facial features in the 2D image, and applying the at least one design guide to the 3D representation.

Abstract: A method of virtually designing a customized healing abutment and a drill guide for a patient, where the method includes: obtaining a CT scan including at least part of the patient's jaw bone; virtually placing at least one implant relative to the jaw bone of the CT scan, such that a planned implant placement is defined; virtually designing: a drill guide for guiding the surgical drilling of a bore for the implant into the patient's jaw bone at the planned implant placement; and a customized healing abutment configured for shaping the soft tissue according to a target profile when arranged in the implant; where the design of the drill guide and of the customized healing abutment is at least partly based on the CT scan and on the planned implant placement.

Abstract: Disclosed is a method for compensating for motion blur when performing a 3D scanning of at least a part of an object by means of a 3D scanner, where the motion blur occurs because the scanner and the object are moved relative to each other while the scanning is performed, and where the motion blur compensation comprises: —determining whether there is a relative motion between the scanner and the object during the acquisition of the sequence of focus plane images; —if a relative motion is determined, performing a motion compensation based on the determined motion; and —generating a 3D surface from the sequence of focus plane images.

Abstract: A method for creating a digital model of a denture for a patient, where the denture includes a gingival part and artificial teeth, includes obtaining digital models of artificial teeth representing the artificial teeth; obtaining a 3D scan comprising a digital representation of at least part of the patient's existing gingiva; digitally modeling a gingival part of the digital model of the denture using the 3D scan and the digital artificial teeth; digitally determining a first offset defining a first thickness of a first portion of the gingival part of the digital model of the denture that extends from the digital representation of the at least part of the patient's existing gingiva; and digitally determining a second offset defining a second thickness of a second portion of the gingival part of the digital model of the denture that extends from the digital artificial teeth.

Abstract: A computer product for generating a digital 3D model for use in a dental component based on a digital 3D model of the dental component showing a shape of the teeth and a digital 3D representation of a pre-prepared set of teeth showing the region for which the dental component is intended, said product causing a system to generate a digital 3D combined model representing a target dental situation when the dental component is arranged at the teeth, where the instructions are configured for digitally replacing one or more teeth of the digital 3D representation of the pre-prepared set of teeth with the digital 3D model of the dental component by digitally removing the one or more teeth of the digital 3D representation of the pre-prepared set of teeth and adding the digital 3D model of the dental component to the digital 3D representation of the pre-prepared set of teeth.
