Abstract:
Disclosed herein is a method that generally relates to comparing a current dental setup with a series of preset dental setups. More particularly a method is disclosed where this comparison is used to determine which aligner should be used from a series of dental aligners for proceeding with an orthodontic treatment.
Abstract:
Disclosed is a method of creating a digital abutment design of a customized dental abutment, the method comprising: - obtaining a bone scan comprising a digital representation of at least a part of a patient's jaw including the surface of the jawbone; and - designing the digital abutment design of the customized dental abutment; wherein the design of the digital abutment design is at least partly based on fulfilling a set of predefined design criteria comprising the relationship between the digital representation of the jawbone and the digital abutment design.
Abstract:
Disclosed is a method, a system and a user interface for generating a digital design for use in the manufacture of a molding-shell for a patient's teeth, where the molding-shell and the teeth together enclose a volume for forming a dental restoration, where the method comprises: - obtaining a digital 3D representation of the patient's teeth, said digital 3D representation comprising a tooth part relating to one or more teeth for which the dental restoration is formed; - obtaining a set of one or more digital teeth anatomies; - arranging the set of digital teeth anatomies and the digital 3D representation according to a preferred relative arrangement; and - generating the digital design where a first portion of the digital design is derived from the digital teeth anatomies and a second portion of the digital design is derived from the tooth part of the digital 3D representation.
Abstract:
There is disclosed a method for manufacturing a denture comprising an artificial gingiva surface, a seating surface facing at least a part of the gingiva surface when placed in the mouth of a patient, at least one tooth receiving hole provided in the artificial gingiva surface and extending through to the seating surface and an artificial tooth arranged in the tooth receiving hole, The method comprises printing an intermediate denture base comprising the artificial gingiva surface, the at least one tooth receiving hole for receiving the artificial tooth, arranging the artificial tooth in the at least one tooth receiving hole, fixing the intermediate denture base in a milling machine, and milling the denture comprising providing the seating surface by removing at least a part of the tooth extending through the tooth receiving hole. This provides an improved manufacturing process of denture.
Abstract:
Disclosed is a drill guide assembly (1) used to guide a drill into the jawbone of a patient during dental surgery, the drill guide assembly comprises at least one through going guide bore (5, 6, 7) for guiding the drill, at least one attachment means (9, 10, 11) for securing a part of the drill guide assembly to the jaw of the patient during surgery, wherein the drill guide assembly comprises a first part (2 and 4) comprising the at least one first through going guide bore (5, 6, 7), the at least one first attachment means (9, 10, 11) and at least a first reference area for referring the first part to a first anatomical feature of the patient, a second part (3) comprising a second reference area for referring the second part (3) to a second anatomical feature of the patient, and a guiding structure (12, 13', 13'') for guiding the first part (2 and 4) and the second part (3) into a desired configuration.
Abstract:
Disclosed is a method, a user interface and a system for use in determining shade of a patient's tooth, wherein a digital 3D representation comprising shape data and texture data for the tooth is obtained. A tooth shade value for at least one point on the tooth is determined based on the texture data of the corresponding point of the digital 3D representation and on known texture values of one or more reference tooth shade values.
Abstract:
Method for digitally designing a denture for a patient, where the denture comprises a plurality of denture teeth, where designing the denture comprises relocating, repositioning and/or rotating the teeth of the denture, and where the denture teeth are grouped in at least two blocks where each block comprises at least two denture teeth, comprising: • obtaining a 3D scan of the upper jaw and lower jaw of the patient; • obtaining a digital 3D arrangement of the denture teeth, where the denture teeth are pre-set in occlusion; • digitally arranging the 3D scan of the upper jaw and lower jaw relative to the 3D arrangement of the denture teeth; • digitally transforming at least one denture tooth based on input from a user; where at least one design rule is enforced that affect one or more, but not all of the blocks, when the at least one denture tooth is transformed.
Abstract:
Disclosed are a scanner system and a method for recording surface geometry and surface color of an object where both surface geometry information and surface color information for a block of said image sensor pixels at least partly from one 2D image recorded by said color image sensor.
Abstract:
Disclosed is a method of virtually designing a reduced shape of at least one artificial tooth adapted to be inserted in a denture for a patient, where the artificial tooth is configured to be provided as a physical artificial tooth and as a corresponding virtual artificial tooth, where the artificial tooth is configured to have an original shape, and where the denture is configured to comprise physical artificial teeth and an artificial gingival, wherein the method comprises: obtaining a 3D digital representation of at least part of the patient's oral cavity; virtually designing the denture by virtually designing the artificial gingival and the placement of the artificial teeth in the artificial gingival based on the 3D digital representation of at least part of the patient's oral cavity; virtually designing a reduced shape of the artificial tooth; virtually determining the part of the artificial tooth to be cut away by milling in a milling machine based on the difference between the original shape of the artificial tooth and the virtually designed reduced shape of the artificial tooth; and where the physical artificial tooth is configured to be placed in a milling fixture, such that the arrangement of the physical artificial tooth relative to the milling fixture is known, whereby the determined part of the physical artificial tooth is configured to be cut away by milling in the milling machine, thereby obtaining a reduced physical artificial tooth.
Abstract:
Disclosed is a method for modeling a digital design of a denture for a patient, said denture comprising a gingival part and a teeth part comprising a set of denture teeth, where the method comprises: - obtaining a digital 3D representation of the patient's gum; - obtaining virtual teeth models corresponding to the denture teeth; - virtually arranging the virtual teeth models in relation to the digital 3D representation of the patient's gum; and - generating a virtual outer gingival surface of the gingival part of the denture
