Abstract:
Disclosed is a method, a system and a user interface for creating a digital restoration design for the manufacture of a dental restoration for one or more of a patient's teeth where minimal manual interaction is required when setting the restoration margin line. The method comprises: - obtaining a digital 3D representation of the patient's unprepared teeth; - obtaining a set of one or more digital teeth anatomies; - arranging the digital teeth anatomies and the digital 3D representation according to a preferred relative arrangement; and - creating a digital restoration design comprising a restoration margin line, where the restoration margin line is derived at least partly from an intersection of the digital 3D representation and the digital teeth anatomies.
Abstract:
Disclosed is a method for designing a virtual dental restoration for manufacturing a dental restoration for a patient, said dental restoration comprising an anatomy portion and a sub-gingival portion, wherein the method comprises: - obtaining a virtual anatomy surface expressing a target shape of the anatomy portion of the dental restoration; and - creating a virtual sub-gingival surface for the sub-gingival portion of the dental restoration; where the created virtual sub-gingival surface is shaped such that it contacts the virtual anatomy surface.
Abstract:
Disclosed is a method, a system, and a user interface for creating a virtual positioning jig for manufacturing a positioning jig, where said manufactured positioning jig is for use in 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; - 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.
Abstract:
Disclosed is a structured light 3D scanner based on the principle of triangulation with a light source for generating a light pattern, two cameras with two-dimensional sensors recording the reflection of the light pattern from a target object, and one axis moving the cameras. Wherein the cameras are arranged with at least partly overlapping fields of view and where the sensors in the cameras are read out partially and concurrently during at least some period of the scanning process, thus providing partial images and where the partial images are merged prior to performing the triangulation calculations.
Abstract:
Disclosed is a 3D scanner for recording topographic characteristics of a surface of at least part of a body orifice, where the 3D scanner comprises: - a main body comprising a mounting portion; - a tip which can be mounted onto and un-mounted from said mounting portion, where said tip is configured for being brought into proximity of said body orifice surface when recording said topographic characteristics such that at least one optical element of the tip is at least partly exposed to the environment in the body orifice during said recording; and - a heater system for heating said optical element, said heater system comprising a source of electromagnetic energy and a receptive element configured for receiving the electromagnetic energy and converting it into heat, where the generated heat is provided by way of thermal conduction directly to said optical element or indirectly through a heat conducting element; where the tip can be sterilized in a steam autoclave when un-mounted from the main body of the 3D scanner such that it subsequently can be reused.
Abstract:
Disclosed is a method of virtually designing a number of 3D teeth restorations for a patient, where the method comprises: - providing a number of initially composed 3D virtual teeth restorations, where each of the virtual teeth restorations is represented by a separate surface; - defining a centre of modification in relation to the initially composed 3D virtual teeth restorations; and - modifying the shapes and/or the positions of at least two of the initially composed 3D virtual teeth restorations simultaneously to obtain a modified set of 3D virtual teeth restorations, where the magnitude of the modification depends on the distance to the centre of modification.
Abstract:
Disclosed are methods and systems for generating a virtual model of a customized impression tray and for manufacturing such a customized impression tray. A 3D digital representation of a patient's set of teeth is obtained and a virtual model of the customized impression tray is generated, where the generating comprises shaping the virtual model of the customized impression tray according to the 3D digital representation.
Abstract:
Disclosed is fixation by means of any type of adhesive of an assembly consisting of two or more sub-parts internally joined rigid together, e.g. a cemented doublet, or - as detailed in an example - a beam splitter. It is often beneficial to constrain the fixation to only one of the subparts in order to prevent either optical degradation of the performance or even physical damages due to thermal stress. The invention consists in limiting the adhesive area by adding a patterned - non adhesive - element to part of the interface.
Abstract:
Disclosed is an integrated 3D scanner for scanning a surface of an object, said integrated 3D scanner comprising: - a scanning device capable of operating in a first configuration and in a second configuration, where • in said first configuration the scanning device is capable of acquiring a first data set relating to the surface of the object; and · in said second configuration the scanning device is capable of acquiring a second data set relating to the surface of the object; - a data processing unit configured for combining one or more first data sets and one or more second data sets to provide a combined data set; where the first and second configurations of the scanning device are such that the second data set represents data with a higher spatial resolution than the first data set. The two configurations may be realized by two separate scanners. The scanning device may scan at different focal planes in the different configurations. The switching between the two configurations may be automatically performed depending on the distance of the scanner from the object.
