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.

Abstract: A method for digitally designing a digital restoration design and a digital reduction coping design, the method includes obtaining a digital 3D representation of the upper jaw and the lower jaw of the patient, the digital 3D representation includes a digital 3D preparation representing at least one preparation targeted for receiving a restoration; digitally determining a reduction surface intersecting the digital 3D preparation, the reduction surface arranged order to meet a minimum thickness requirement for the digital restoration design; and digitally designing the digital restoration design and the digital reduction coping design based at least on the reduction surface and the digital 3D preparation. This allows designing the reduction coping and the restoration at the same time and thereby reduces chair time and visits by the patient.

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: Detecting a movable object in a location includes providing a first 3D representation of at least part of a surface; providing a second 3D representation of at least part of the surface; 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: A method for visualising a 3D dental restoration on a 2D image of the mouth of a patient includes 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 including 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.
