A method for digitally designing a denture for a patient, where the denture includes a plurality of denture teeth, where designing the denture includes transforming denture teeth of the denture, wherein the method includes 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 grouping the denture teeth in four groups, the four groups includes an upper anterior group, a lower anterior group, a left posterior group, and a right posterior group; and digitally arranging the upper anterior group first, the left and right posterior groups second and the lower anterior group third.

Snapping of denture teeth

A scanner includes a camera, a light source for generating a probe light incorporating a spatial pattern, an optical system for transmitting the probe light towards the object and for transmitting at least a part of the light returned from the object to the camera, a focus element within the optical system for varying a position of a focus plane of the spatial pattern on the object, unit for obtaining at least one image from said array of sensor elements, unit for evaluating a correlation measure at each focus plane position between at least one image pixel and a weight function, a processor for determining the in-focus position(s) of each of a plurality of image pixels for a range of focus plane positions, or each of a plurality of groups of image pixels for a range of focus plane positions, and transforming in-focus data into 3D real world coordinates.

Intraoral scanning apparatus

A method for manufacturing/producing a dental restoration for a patient, where the method includes: obtaining a 3D scan of at least a restoration site of the patient's mouth, where the manufactured dental restoration is adapted for fitting to the restoration site; obtaining a computer-aided design (CAD design) of the dental restoration; milling the restoration from a material, where the restoration is milled both on an inside surface configured for fitting to the shape of the restoration site of the patient's mouth and on an outside surface, where the milling is according to the obtained CAD design; transferring the milled restoration to a retention means providing a fixed known position of the restoration relative to a post-processing machinery, where the restoration is retained on the inside surface, such that the outside surface of the restoration is approachable/free/accessible; and performing post-processing of the outside surface of the restoration.

Automated production of dental restoration

Disclosed herein is method for designing a dental prosthesis and a positioning guide for placing the dental prosthesis on implants in the jaw while maintain proper occlusion. In particular the method relates to a method for designing the dental prosthesis and the positioning guide prior to implant placement. Accordingly, the disclosure relates to a method and a kit of components suited for one-day implant surgery thereby reducing the time the patient spend in the dentist chair.

Method for providing a dental prosthesis and a positioning guide for placing the dental prosthesis

According to an embodiment, a method for generating a digital data set for fabricating a physical dental bleaching tray useable to deliver an bleaching agent is disclosed. The method includes obtaining a three-dimensional digital representation of a patient's dentition including teeth and gingiva; segmenting two or more teeth into individual tooth; identifying a facial surface of at least one of the segmented tooth; defining a facial surface portion including a surface area that is at least partly bound by a virtual boundary that is non-interfacing with the gingiva; generating a modified three-dimensional digital representation using the defined facial surface portion; and generating, based on the modified three-dimensional digital representation, the digital data set configured to be used in fabricating the physical dental bleaching tray.

System and method for fabricating a dental tray

Disclosed are methods and digital tools for deriving tooth condition information for a patient's teeth, for populating a digital dental chart with derived tooth condition information, and for generating an electronic data record containing such information.

Deriving tooth condition information for populating digital dental charts

A method of designing a virtual 3D model of a dental restoration for a target site of a patient's set of teeth, the method including: obtaining a digital 3D representation of the set of teeth, the digital 3D representation including a section corresponding to the target site; determining an insertion path for the dental restoration to the target site; and designing the virtual 3D model of the dental restoration based on the digital 3D representation of the set of teeth, where the designing includes generating an outer surface of the virtual 3D model, where the determined insertion path and the outer surface of the designed virtual 3D model provide that a dental restoration manufactured from the designed virtual 3D model can be moved along the insertion path to the target site.

Designing an insertable dental restoration

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.

Detection of a movable object when 3D scanning a rigid object

A 3D scanner system includes a scanning device capable of recording first and second data sets of a surface of an object when operating in a first configuration and a second configuration, respectively. A measurement unit is configured for measuring a distance from the scanning device to the surface. A control controls an operation of the scanning device based on the distance measured by the measurement unit, where the scanning device operates in the first configuration when the measured distance is within a first range of distances from the surface and the scanning device operates in the second configuration when the measured distance is within a second range of distances; and a data processor is configured to combine one or more first data sets and one or more second data sets to create a combined virtual 3D model of the object surface.

Dual-resolution 3D scanner and method of using

A method of aligning two 3D digital representations of at least a part of each of the upper and lower jaw of a patient, the method including segmenting the 3D digital representations to determine the shape and position of each of the patient's teeth in each of the 3D digital representations; and using a set of known anatomical concepts to constrain the fit of the two 3D digital representations to get a preliminary fit.
