Method for registering individual three-dimensional optical images to form an overall image of a tooth situation

摘要

Method for registering individual three-dimensional optical recordings (1) to form an overall recording (50) of a tooth situation comprising an upper jaw (2) and a lower jaw (3), wherein a first 3D model (6) of a first section of the upper jaw and a second 3D- Model (8) of a second section of the lower jaw are generated from the individual recordings, characterized in that a geometric positional relationship between the first 3D model (6) and the second 3D model (8) is determined, the determination of the positional relationship under A lateral receptacle (20, 21, 22) and a contact pattern (31, 32) are used, the lateral receptacle (20, 21, 22) having a receiving area which at least partially encompasses the first section of the upper jaw (2) and at least partially comprises the second section of the lower jaw (3), the contact pattern comprising a plurality of contact areas (31, 32) between the upper jaw and the lower jaw and the like mfasst, the contact pattern (30, 31, 32) being measured by means of an occlusion paper (29) by placing the occlusion paper (29) between the upper jaw (2) and the lower jaw (3) and then the upper jaw (2) and the The lower jaw (3) is brought into a final bite position, with the individual recordings (1) being measured after the occlusion paper has been removed again, so that the contact areas of the contact pattern on the upper jaw (2) and the lower jaw (3) are recorded, wherein the generated first 3D model (6) and the generated second 3D model (8) are analyzed by means of a computer (10) in order to determine the position of the contact areas.
