Abstract
A system and a method for providing a model of a superstructure joining a denture and a corresponding dental arch, the method includes the steps of obtaining a first 3D representation of at least a part of a preliminary model of the denture, obtaining a second 3D representation of at least a part of the dental arch comprising dental implants, and generating a model of a superstructure based on the first 3D representation, the second 3D representation, dental implant positions and dental implant orientations.
Claims34
A method for providing a model of a superstructure joining a denture and a corresponding dental arch, the method comprising:
- obtaining a first digital 3D representation of at least a part of a preliminary model of the denture,
- obtaining a second digital 3D representation of at least a part of the dental arch comprising dental implants,
- using a computer to modify the first digital 3D representation and the second digital 3D representation to generate a digital model of the superstructure based on the first 3D representation, the second 3D representation, dental implant positions and dental implant orientations, and
- segmenting teeth and gingiva or segmenting individual teeth in the first or second 3D representation, at least partly based on a computer algorithm.
A system for providing a model of a superstructure joining a denture and a corresponding dental arch, the system comprising:
- means for obtaining a first digital 3D representation of at least a part of a preliminary model of the denture,
- means for obtaining a second digital 3D representation of at least a part of the dental arch comprising dental implants, and
- a computer configured to modify the first digital 3D representation and the second digital 3D representation to generate a model of a superstructure based on the first 3D representation, the second 3D representation, dental implant positions and dental implant orientations.
