Abstract
A method, a system, and a user interface for creating a virtual positioning jig for manufacturing a positioning jig, where the manufactured positioning jig is for use in positioning a manufactured dental restoration at a patient's set of teeth, the method including: obtaining a digital 3D representation of the set of teeth; designing a virtual model of the dental restoration at the digital 3D representation; creating an inner surface and an outer surface of the virtual positioning jig; and defining a through hole of the virtual positioning jig at the implant region.
Claims21
A method for creating a virtual positioning jig for manufacturing a positioning jig, where said manufactured positioning jig is configured for use when positioning a manufactured dental restoration at a patient's set of teeth, said method comprising:
- obtaining a digital 3D representation of the set of teeth, said digital 3D representation comprising an implant region portion relating to an implant region and a neighbor region portion relating to a neighbor region of the set of teeth;
- designing a virtual model of the dental restoration at the digital 3D representation such that the designed virtual dental restoration model is arranged according to a target arrangement relative to the digital 3D representation, said virtual dental restoration model comprising an outer restoration surface;
- creating an inner surface and an outer surface of the virtual positioning jig, where the inner jig surface is created based on said outer restoration surface, the target arrangement, and the neighbor region portion of the digital 3D representation;
- and
- defining a through hole of the virtual positioning jig at the implant region portion of the digital 3D representation, where the through hole extends from the inner jig surface to the outer jig surface.
