Method of modifying the gingival part of a virtual model of a set of teeth

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, the 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.

Designing a virtual preparation and a virtual gingival

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

A method of designing a virtual 3D model of a dental restoration for a target site of a patient's set of teeth, the method including-obtaining a digital 3D representation of the set of teeth, the digital 3D representation comprising a section corresponding to the target site; determining an insertion path for the dental restoration to the target site; and designing the virtual 3D model of the dental restoration based on the digital 3D representation of the set of teeth, where the designing includes generating an outer surface of the virtual 3D model, where the determined insertion path and the outer surface of the designed virtual 3D model provide that a dental restoration manufactured from the designed virtual 3D model can be moved along the insertion path to the target site.

A method of digitally designing a dental component for a patient, wherein the method includes: obtaining a 3D representation of the patient's upper jaw; obtaining a 3D representation of the patient's lower jaw; obtaining at least a first 3D representation of a first bite configuration of the patient's jaws in a first occlusion and a second 3D representation of a second bite configuration of the patient's jaws in a second occlusion different from the first occlusion; digitally determining a occlusal contact movement of the patient's jaws relative to each other based on the at least first 3D representation, the second 3D representation and contact between the patient's upper jaw and lower jaw; and digitally designing the dental component based on the occlusal contact movement of the patient's jaw relative to each other.

Multiple bite configurations

A method, a system and a user interface for creating a digital restoration design for the manufacture of a dental restoration for one or more of a patient's teeth where minimal manual interaction is required when setting the restoration margin line includes obtaining a digital 3D representation of the patient's unprepared teeth; obtaining a set of one or more digital teeth anatomies; arranging the digital teeth anatomies and the digital 3D representation according to a preferred relative arrangement and creating a digital restoration design including a restoration margin line, where the restoration margin line is derived at least partly from an intersection of the digital 3D representation and the digital teeth anatomies.

Creating a digital restoration design
