ABSTRACT:
The invention comprises a pair of one-piece, flat recording plates that are mirror symmetric about a sagittal plane S, or which an upper part (200), which is provided with a stylus (202), can be affixed to the upper jaw of the patient, and a lower part (100), which is provided with a writing surface (101), can be affixed to the lower jaw of the patient. A recording plate comprises a planar base area (110; 210), planar transition areas (113, 114; 213, 214), which border thereon, and supporting surfaces (111, 112; 211, 212), which border on the latter and which have continuous retention openings (119; 219). The base area is approximately shaped in the form of a forward tapering isosceles trapezoid, which is mirror symmetric about the sagittal plane S, whereas each transition area is approximately shaped in the form of an elongated parallelogram, which is angled away both from the base area as well as from the supporting surface. As a result, the supporting surfaces are offset from the plane of the base area whereby, in the upper recording plate, they are downwardly offset and, in the lower recording plate, they are upwardly offset. The supporting surfaces are upwardly angled with regard to the base area of the respective recording plate at approximately the same angle. Corner areas (124, 125; 224, 225) of the supporting surfaces located outside and at the rear are approximately shaped in the form of an isosceles right triangle and are upwardly angled.
