EQUIPMENT AND METHOD OF MEASURING ANGLE BETWEEN CAMPER PLANE AND HIP PLANE, AND METHOD OF MANUFACTURING FALSE TOOTH BY USING SAME ANGLE

摘要

PURPOSE:To measure an angle made by a Camper plane and a plane including the bihamular notch and incisive papilla of the upper jaw (HIP plane) by regulating a rotating plane part so as to parallel one line on the rotating plane part with the Camper plane while keeping of the standard plane part in parallel with the HIP plane. CONSTITUTION:The center part 2a of a standard plane part 2 of a Camper HIP deviation angle gauge 1 is inserted into the mouth. A side plane part 3 and a rotating plane part 4 are made of transparent material, and several straight lines parallel with the standard plane part are carved on the rotating plane part 4. While the standard plane part 2 is held in the state parallel to the HIP plane, the rotating plane part 4 is moved vertically or property rotated to the side plane part 3 so as to contain one line on the rotating plane part 4 in the plane CAMPER including the wings of the nose N and the external auditory miatus upper edge E, and the both plane parts are fixed to each other. The angle theta made by a line on the side plane part and a line on the rotating plane part 4 is practically equal to the angle made by the Camper plane and the HIP plane.
