ABSTRACT:
An occlusal force-meter 1 includes an occlusal force detecting portion 2 for detecting an occlusal force and a main body 3 for processing the detected signal obtained by the occlusal force detecting portion 2 to display the occlusal force measured value on a display 4. The occlusal force detecting portion 2 includes a transmitting portion (second pressure transmitting portion) 5 having diaphragm portions 7, 8 at an upper surface and/or a lower surface of one end portion 5f thereof. A pressure medium liquid L is filed therein, for transmitting the occlusal force added to the diaphragm portions 7, 8 to a pressure detector 9 disposed on the other end portion 5r thereof. A first pressure transmitting portion 10 is positioned between teeth T and the diaphragm portions 7, 8 at the time of occlusion of the tested person for adding the occlusal force to surfaces of the diaphragm portions 7, 8 perpendicularly through the pressure applied surfaces of the diaphragm portions 7, 8 perpendicularly through the pressure applied surfaces Fu, Fd abutted to outer surfaces of the diaphragm portions 7, 8.
