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.

Abstract: The invention relates to a method for recording individual three-dimensional optical images (1) to form a global image (50) of a tooth situation comprising an upper jaw (2) and a lower jaw (3). A first 3D model (6) of a first subsection of the upper jaw and a second 3D model (8) of a second subsection of the lower jaw are produced from the individual images. Subsequently, a geometric positional relationship between the first 3D model (6) and the second 3D model (8) is determined, said positional relationship being determined by using a lateral image (20, 21, 22) and/or using a contact pattern (31, 32). Said lateral image (20, 21, 22) comprises an image area which comprises at least part of the first subsection of the upper jaw (2) and at least part of the second subsection of the lower jaw (3). Said contact pattern comprises several contact areas (31, 32) between the upper jaw and the lower jaw. Said contact pattern (30, 31, 32) is measured by means of an occlusion paper (29).
