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 ().
