Method, system and user interface for creating a digital design for use in manufacturing a molding-shell for a dental restoration

A system for designing a digital design for manufacturing a molding-shell for a patient's tooth, where the molding-shell and the tooth together enclose a volume for forming a dental restoration, wherein the system comprises:

• a computer device comprising a non-transistory computer readable medium and an electronic data processing device, where said computer device is capable of obtaining a set of one or more digital teeth anatomies and a digital 3D representation of the patient's teeth, where said digital 3D representation comprises a tooth part relating to one or more teeth for which the dental restoration is formed;
• a visual display unit for displaying the one or more digital teeth anatomies and the digital 3D representation of the patient's tooth;
• and
• digital tools allowing an operator to arrange the set of one or more digital teeth anatomies and the digital 3D representation according to a preferred relative arrangement;
• where the computer readable medium comprises computer code which when executed on the electronic data processing device generates the digital design, where a first portion of the digital design is derived from the one or more digital teeth anatomies and a second portion of the digital design is derived from the tooth part of the digital 3D representation.
