The occlusal plane plate used in the prior art only has occlusal plane indicating wings, so that the occlusal plane plate needs to be matched with a ruler for use, the front part of the occlusal plane is firstly trimmed, the occlusal plane plate is determined to be parallel to the connecting line of pupils, and then the rear part of the occlusal plane plate is trimmed again to be parallel to the connecting line of the nasal wings of the tragus. Because the relationship between the trim occlusion plane and the pupil line and the tragus-nose line cannot be displayed at the same time, when the trim occlusion plane is parallel to one of the lines, the trim occlusion plane can be influenced to be parallel to the other line. Therefore, the existing simple occluding plane plate is complicated to use and easy to generate errors. The measuring plate for the oral cavity intersection plane provided by the utility model is added with the dimension scale on the middle positive indication rod, and other tools are not required to be matched during measurement, further, the distance between the middle positive indication rod of the measuring plate and/or the two tragus and nose wing indication wing plates and/or the vertical distance between the tragus and nose wing indication wing plates and the bifurcation plate are/is adjusted, the measuring plate can be suitable for the testee with various facial shapes and sizes, more data can be measured by arranging lines on the bifurcation plate, and various data required by one-time occlusion can be measured at the same time, so that the measuring method is simplified, the measuring error is eliminated, and the measuring precision is improved. For the specific structure of the adjustment of the spacing between the respective components, in addition to the adjustment structure exemplified in the present embodiment, a structure capable of performing the same adjustment function is also within the scope of the present utility model.
