Abstract
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.

A method for creating a digital restoration design comprising a restoration margin line for the manufacture of a table-top restoration for one or more of a patient's teeth, wherein the method comprises:
- obtaining a digital 3D representation of the one or more of the patient's teeth, when the one or more of the patient's teeth are unprepared, in a coordinate system;
- downloading a set of one or more digital 3D teeth anatomies expressing a desired target shape of the table-top restoration;
- mapping the set of the one or more digital 3D teeth anatomies into a common coordinate system with the digital 3D representation of the one or more of the patient's unprepared teeth, or vice versa;
- arranging the set of the one or more digital 3D teeth anatomies and the digital 3D representation of the one or more of the patient's unprepared teeth according to a preferred relative arrangement in the common coordinate system;
- defining a restoration margin line at least partly by identifying a plurality of locations where an outer surface of the digital 3D representation of the one or more of the patient's unprepared teeth intersects with a surface of the set of the one or more digital teeth anatomies after the digital 3D teeth anatomies and the digital 3D representation of the one or more of the patient's unprepared teeth are arranged according to the preferred relative arrangement;
- and
- creating, by modifying the downloaded set of the one or more digital 3D teeth anatomies, the digital restoration design.
A method for creating a digital restoration design comprising a restoration margin line for the manufacture of a minimum-preparation veneer for one or more of a patient's teeth, wherein the method comprises:
- obtaining a digital 3D representation of the one or more of the patient's teeth, when the one or more of the patient's teeth are unprepared;
- downloading a set of one or more digital 3D teeth anatomies expressing a desired target shape of the dental restoration;
- mapping the set of the one or more digital 3D teeth anatomies into a common coordinate system with the digital 3D representation of the one or more of the patient's unprepared teeth, or vice versa;
- arranging the set of the one or more digital 3D teeth anatomies and the digital 3D representation of the one or more of the patient's unprepared teeth according to a preferred relative arrangement in the common coordinate system in which the manufactured minimum-preparation veneer improves the aesthetic appearance of the patient's teeth;
- defining a restoration margin line at least partly by identifying a plurality of locations where an outer surface of the digital 3D representation of the one or more of the patient's unprepared teeth intersects with a surface of the set of the one or more digital teeth anatomies after the set of one or more digital 3D teeth anatomies and the digital 3D representation of the one or more of the patient's unprepared teeth are arranged according to the preferred relative arrangement;
- and
- creating, by modifying the downloaded set of one or more digital 3D teeth anatomies, the digital restoration design.
A method for creating a table-top restoration for one or more of a patient's teeth, wherein the method comprises:
- acquiring a digital design for a table-top restoration, wherein the digital design is created by:
- obtaining a digital 3D representation of the one or more of the patient's teeth, when the one or more of the patient's teeth are unprepared;
- downloading a set of one or more digital 3D teeth anatomies expressing a desired target shape of the table-top restoration;
- mapping the set of the one or more digital 3D teeth anatomies into a common coordinate system with the digital 3D representation of the one or more of the patient's unprepared teeth, or vice versa;
- arranging the set of the one or more digital 3D teeth anatomies and the digital 3D representation of the one or more of the patient's unprepared teeth according to a preferred relative arrangement in the common coordinate system;
- defining a restoration margin line at least partly by identifying a plurality of locations where an outer surface of the digital 3D representation of the one or more of the patient's unprepared teeth intersects with a surface of the set of the one or more digital teeth anatomies after the digital 3D teeth anatomies and the digital 3D representation of the one or more of the patient's unprepared teeth are arranged according to the preferred relative arrangement;
- creating, by modifying the downloaded set of one or more digital 3D teeth anatomies, the digital restoration design;
- and
- manufacturing the table-top restoration using the acquired digital design for the table-top restoration.
