Abstract: 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.

Abstract: The invention relates to a method for contructing at least one dental prosthetic part (20) or a bracket, with at least one adhesive surface (2), in which a 3D model (1) is made of the dental prosthetic part (20). Recesses (3,9,12,15,29,31) are constructed on the adhesive surface (2) of the 3D model (1).

Abstract: The invention relates to a method and to a camera for the three-dimensional measurement of a dental object, comprising at least one light source, which emits an illumination beam, at least one projection means, which produces a projection pattern, focusing optics, which 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. In 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 varied incrementally between a plurality of defined scan positions.

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.
