The invention relates to a measuring system for measuring an implant-implant situation for planning an implant-supported tooth replacement part supported on at least two implants, comprising a scanning template and the at least two set implants. The scanning template has cut-outs for the individual implants, wherein first markings are arranged on surface regions around the cut-outs.

Measuring system and method for measuring an implant-implant situation

A method of performing a three-dimensional (3D) scan of an object includes applying an optical contrast powder to the object and illuminating the object with light. First and second two-dimensional (2D) color image data corresponding to the object is generated. First and second 2D monochrome image data corresponding to the object is generated using the first and second 2D color image data. 3D data corresponding to the object is generated using the first and second monochrome 2D image data. Color 3D image data corresponding to the object is generated by adding color information to the 3D data. The color 3D image data is displayed.

The invention relates to a method and a camera for the three-dimensional measurement of a dental object, comprising at least one light source that emits an illumination beam, at least one projection mask that produces a projection pattern, focusing optics that display the projection pattern in a plane of sharp focus at a defined focal distance relative to the dental camera. The projection pattern projected onto the object is reflected by the object as an observation beam and is acquired by means of a sensor. During the measurement of the object, the focusing optics are controlled in such a way that the focal distance of the plane of sharp focus relative to the camera is adjusted incrementally between a number of defined scan positions.

The method for optical three-dimensional surveying using an intraoral camera (), wherein the intraoral camera () provides that a 3D image is created from at least one of the 2D recorded images or from at least one of the sequences, and wherein a plurality of all the 2D recorded images and/or sequences created in a first operating mode (M) are used to create at least one overall 3D image. In addition, the method provides that a selection is made between the first operating mode (M) and a second operating mode (M), wherein a plurality of all 2D recorded images and/or sequences created during an interval of time (T) are used in the second operating mode (M) to create at least one 3D image immediately before and/or after a triggering command (A).

The invention relates to a method for the optical three-dimensional measurement of a dental object, wherein a first region of the dental object is measured using a first optical three-dimensional measurement method, wherein the first optical three-dimensional measurement method is based on a triangulation method and on a fringe projection method. According to the invention, a powdering occurs at least on the first region, wherein first image data are generated. Using a less precise, second optical three-dimensional measurement method, a second region of the dental object is subsequently measured without previous powdering, wherein second image data are generated. Afterwards, the first image data are combined with the second image data to form an overlapping three-dimensional exposure.

A method for recording an image of an object includes projecting a strip pattern onto the object, recording the projected strip pattern as raw image data using a camera, and calculating an image of the object from the raw image data. A strip pattern having a duty cycle of less than 1 can be used to increase measuring precision during measurement of a translucent object, and can eliminate a need for additional contrast agents for a recording of the object.
