PROBLEM TO BE SOLVED: To provide an occlusion contact checking system required for occlusion adjustment. SOLUTION: The replica of an occlusion contact surface stereoscopically prepared by occlusion is measured and imaged for the intensity of light transmitted through the replica and the position by performing transmission light type scanning by using an image scanner. Thus, a perforation part and a part to be thinned are detected. Similarly, reflected light type scanning is performed and measurement and imaging are performed for the intensity and position of the light reflected on a replica surface. Thus, the three-dimensional image of an occlusion surface is obtained. The measurement is performed from an upper jaw occlusion surface side and from a lower jaw occlusion surface side in the same replica. Image information obtained by scanning the two surfaces on the upper jaw occlusion surface side and the lower jaw occlusion surface side of the replica three-dimentionally prepared by the occlusion by the two systems of a transmission light type and a reflection light type is inputted to a personal computer. The inputted image information is processed and edited by an image processing software and a computer image for analyzing the occlusion of teeth or fillings and an occlusion contact surface state is prepared and displayed on a display. |
