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 ). |
