  • Patent number: 12025427
    Abstract: The invention relates to an optical measuring method for the three-dimensional detection of the surface of an object using an optical recording unit. The optical recording unit is moved relative to the object during a first measurement time interval, height maps are successively detected by the recording unit at a recording frequency, and at least some of the detected height maps are each added to an overall height map and displayed. The recording frequency is regulated by control signals during the measurement time interval. The control signals are generated spaced apart in time and for the purposes of producing each control signal, a statistic for the quality of the height map is determined for the respectively last detected height image and used for producing the control signal.

  • Patent number: 11361524
    Abstract: The quality of digital impressions geometry and color but also fluorescence, transillumination, reflection and absorption properties can be inferior to single frame 2D/3D images e.g. due to averaging effects, rendering effects, difficult scanning situation etc. This can lead to difficulties in the dental workflow such as the creation of a preparation margin line or detection of diseases such as caries. By providing a correlated view of high-quality single frame images and corresponding 3D models, the dental workflow can be guided to be completed more efficiently using the single frame images.

  • Patent number: 11109947
    Abstract: The invention relates to a method for performing an optical three-dimensional recording by using hand-held dental camera. The camera automatically records a plurality of individual optical recordings in succession at a defined frequency during the measurement. The individual three-dimensional optical recordings are combined into an overall recording of a dental object to be measured and before the measurement is performed, a three-dimensional standard jaw model is displayed using a display device and a first control point on the standard jaw model is displayed using the display device. The hand-held dental camera is then positioned in relation to the object to be recorded in such a way that the camera points at the first control point of the standard jaw model and records a corresponding recording region of the dental object.

  • Patent number: 10325365
    Abstract: The invention relates to a method for measuring a dental object (1) using a dental camera (2). During measurement, several optical three-dimensional images (3, 50, 51) of the object (1) are produced. During measurement, an acoustic sound (10, 12) is generated by means of a sound producer (9, 11), said sound (10, 12) being used as feedback for the user and information relating to the current status of a recording of the images (3, 50, 51) and/or relating to image requirements of the dental camera (2) are transmitted to the user. Then, each individual image (3, 50, 51) it is automatically checked by a computer (6) as to whether an overlapping area (7, 8) between the images (3, 50, 51) which are to be combined meets the defined recording requirements for a correct recording.

  • Publication number: 20180240270
    Abstract: The invention relates to a method for recording individual three-dimensional optical images to form a global image of a tooth situation comprising an upper jaw and a lower jaw. A first 3D model of a first subsection of the upper jaw and a second 3D model of a second subsection of the lower jaw are produced from the individual images. Subsequently, a geometric positional relationship between the first 3D model and the second 3D model is determined, said positional relationship being determined by using a lateral image and/or using a contact pattern. Said lateral image comprises an image area which comprises at least part of the first subsection of the upper jaw and at least part of the second subsection of the lower jaw. Said contact pattern comprises several contact areas between the upper jaw and the lower jaw. Said contact pattern is measured by means of an occlusion paper.
