Abstract:
Disclosed herein is a method of reducing the x-ray dose of a patient in an x- ray system, comprising defining a region of interest of the patient, obtaining at least two tracking images of a tracking element taken with at least one camera having a known positional relationship relative to an x-ray source and/or sensor, determining any movement of the tracking element between the acquisition of at least two tracking images, adjusting the collimator of the x-ray source to compensate for any movement of the tracking element between the acquisition of the at least two tracking images, providing that the field of exposure of the x-ray source is confined to the region of interest and obtaining at least one x-ray image of the region of interest after the adjustment of the collimator.
Abstract:
Disclosed is a method for scanning an edentulous patent who has a denture, where an impression material arranged at the gum-facing surfaces of the dentures is shaped by the patient's gums and both the teeth side and the gum-facing surface of the denture is scanned and the obtained digital 3D representations are used to determine the relative arrangement of the patient's edentulous jaws in a bite determined by the dentures.
Abstract:
Disclosed is a method, an occlusion setup fixture and system for recording digital 3D representations of physical teeth models of a patient's jaws and for arranging the digital 3D representations according in a common coordinate system such that the digital 3D representations are arranged according to the patient's occlusion. The recorded digital 3D representations are virtually brought into occlusion by a virtual movement, where the virtual movement comprises a translation along a path according to the confined relative movement of the occlusion setup fixture.
Abstract:
Method for digitally designing at least two attachment abutments, each attachment abutment comprising an implant connection section adapted for connection to a respective implant along an implant axis, a transition section separating the implant connection section from an attachment section, wherein the attachment section is adapted for receiving a mating part, the method comprises the steps of, - obtaining a digital 3D representation of at least a part of a jaw comprising information on the location and orientation of at least two implants extending along respective implant axes within the jaw represented by the digital 3D representation, - digital selecting the shape of the respective connection section from a set of pre-determined digital connection shapes for each attachment abutment, - digital aligning the implant connection sections of the attachment abutments to coextend along the implant axis of the respective implants, - digital selecting the shape of the respective attachment section from a set of pre-determined digital attachment shapes for each attachment abutment, - digital generating the transition section extending between the respective connection section and the respective attachment section of each abutment attachment.
Abstract:
The invention relates to a method for visualising a 3D dental restoration on a 2D image of the mouth of a patient, wherein the method comprises obtaining a 3D dental model of at least a part of the patient's oral cavity, designing the 3D dental restoration, obtaining the 2D image of the mouth of the patient, estimating a virtual camera comprising at least one virtual camera property corresponding to at least one physical camera property of the physical camera used to obtain the 2D image, viewing the 3D dental restoration using the virtual camera, determining the visible area of the 3D dental restoration, which is not overlapped by surrounding anatomic features when viewed with the virtual camera, imaging the visible area of the 3D dental restoration with the 2D image. This advantageously provides an image which with high accuracy gives the dentist and the patient a visual presentation of the final result of a dental treatment.
Abstract:
Disclosed is a method for designing a virtual mould used for manufacturing a corresponding physical mould adapted to be used in manufacturing of a dental restoration for a patient, wherein the method comprises: - obtaining a 3D representation of the patient's set of teeth comprising a restoration site where the manufactured dental restoration is adapted to be arranged; - virtually designing at least a first layer and a second layer of the dental restoration, where the first layer is part of a first portion of the dental restoration, and where the combination of the first portion and the second layer provides at least part of the dental restoration; and - virtually designing the mould, which is adapted for the manufacturing of the second layer, where the inside surface of the mould is adapted to match the combination of at first portion and the second layer, where the inside surface of the mould corresponds to the shape of the dental restoration, where virtually designing the mould comprises designing a virtual retention structure of the mould, where the corresponding physical retention structure is applicable in retaining the first portion of the dental restoration in its correct position in the mould.
Abstract:
Disclosed is a method for detecting a movable object in a location, when scanning a rigid object in the location by means of a 3D scanner for generating a virtual 3D model of the rigid object, wherein the method comprises: providing a first 3D representation of at least part of a surface by scanning at least part of the location; providing a second 3D representation of at least part of the surface by scanning at least part of the location; determining for the first 3D representation a first excluded volume in space where no surface can be present; determining for the second 3D representation a second excluded volume in space where no surface can be present; if a portion of the surface in the first 3D representation is located in space in the second excluded volume, the portion of the surface in the first 3D representation is disregarded in the generation of the virtual 3D model, and/or if a portion of the surface in the second 3D representation is located in space in the first excluded volume, the portion of the surface in the second 3D representation is disregarded in the generation of the virtual 3D model.
Abstract:
Disclosed is a method for modeling and manufacturing a denture for a patient, where the denture comprises a gingival part and artificial teeth, wherein the method comprises: providing a 3D scan comprising at least part of the patient's oral cavity; virtually modeling at least part of the denture using the 3D scan; obtaining virtual teeth to represent the artificial teeth; virtually modeling at least one of the virtual teeth to obtain a set of modeled virtual teeth; manufacturing the modeled virtual teeth in a first material; manufacturing the gingival part in a second material; and manufacturing at least part of the denture by means of computer aided manufacturing (CAM).
Abstract:
Disclosed is a method of designing a dental restoration (1140) for a patient, wherein the method comprises: -providing one or more 2D images (1101), where at least one 2D image (1101) comprises at least one facial feature (1103); -providing a 3D virtual model (1102) of at least part of the patient's oral cavity; -arranging at least one of the one or more 2D images (1101) relative to the 3D virtual model (1102) in a virtual 3D space such that the 2D image (1101) and the 3D virtual model (1102) are aligned when viewed from a viewpoint, whereby the 3D virtual model (1102) and the 2D image (1101) are both visualized in the 3D space; and -modeling a restoration (1140) on the 3D virtual model (1102), where the restoration is designed to fit the facial feature (1103) of the at least one 2D image (1101).
