  • Patent number: 11129522
    Abstract: The invention relates to a measurement system for optically measuring an object, comprising a dental camera and an optical attachment. In this case the optical attachment comprises at least one lens, which is shaped and arranged in such a way that the optical attachment has a negative focal length so that a measurement field or a measurement volume of the dental camera is enlarged by the optical attachment.
    Type: Grant

  • Patent number: 10438417
    Abstract: The invention concerns a device (1) for editing a virtual 3-D model (2) of teeth (2.1, 2.2, 2.3, 2.4) positioned in a dental arch (9, 11) by means of a virtual tool (21, 22, 23, 24, 25, 26, 27, 28, 50). The tool (21, 22, 23, 24, 25, 26, 27, 28, 50) can be used on a first tooth (2.1, 2.3) of the 3-D model (2), whereby the corresponding application is carried out on a second mirrored tooth (2.2, 2.4), contralateral to the first tooth with respect to a plane of symmetry (12), that is, on the tooth on the other side of the plane of symmetry (12), which is positioned as a mirror image of the first tooth (2.1, 2.3) with respect to the plane of symmetry (12).

  • Patent number: 7801632
    Abstract: A method and apparatus for designing the surface of a dental prosthetic item consisting of three-dimensional data, wherein three-dimensional data of a surface (30) of an electronically stored tooth (11) are used at least as part of the surface of the dental prosthetic item to be fabricated, to which end the surface of the tooth (30) is first of all determined as to size and then placed against an electronically stored prosthetic item or the region of a preparation site (1;21) existing as three-dimensional data. The position of the digital tooth surface (30) over the dental prosthetic item or in the preparation site (1; 21) can be set with regard to at least one spatial axis and/or at least one direction of rotation.

  • Publication number: 20040185422
    Abstract: The invention relates to a data base for the storage of data, which comprises dental data relating to real teeth in the form of digitized images, which digitized images involve universally applicable dentition-specific and/or universally applicable tooth-specific features or structural properties, such as sex-specific and/or tooth family-specific and/or biography-specific and/or person-specific characteristics, with or without anomalous characteristics.
