The purpose of the present invention is to provide an occlusal pressure analysis device which can measure occlusal pressure with high positional accuracy using data obtained by a commonly used method. This occlusal pressure analysis device is provided with an arithmetic unit which: calculates a first dental arch formula on the basis of occlusal pressure data; calculates a second dental arch formula on the basis of occlusion contact position data; calculates a transformation matrix for approximating the first dental arch formula to the second dental arch formula; performs computation for converting positional information contained in the occlusal pressure data into new positional information by means of the transformation matrix; and outputs occlusal pressure data that contains the new positional information.
