METHOD FOR RECORDING INDIVIDUAL THREE-DIMENSIONAL OPTICAL IMAGES TO FORM A GLOBAL IMAGE OF A TOOTH SITUATION

摘要

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).

1. 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, wherein 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 generated from the individual images, characterized in that a geometric positional relationship between the first 3D model and the second 3D model is determined, wherein the positional relationship is determined using a lateral image and/or using a contact pattern, wherein the lateral image has an image area which at least partially comprises the first subsection of the upper jaw and at least partially comprises the second subsection of the lower jaw, wherein the contact pattern comprises a plurality of contact areas between the upper jaw and lower jaw, wherein the contact pattern is measured by means of an occlusion paper in that the occlusion paper is placed between the upper jaw and the lower jaw, and then the upper jaw and the lower jaw are brought into a closed-bite position, wherein after the occlusion paper is removed, the individual images are then measured such that the contact areas of the contact pattern are detected on the upper jaw and the lower jaw, wherein the generated first 3D model and the generated second 3D model are analyzed by means of a computer in order to determine the position of the contact areas.
