Up to now, we have been using calipers to measure mandibular position, but this method does not assure accurate measurements of andibular position. We have developed a small and light electronic measuring device which can measure mandibular position through magnetic sensors. This device consists of a magnet attached on the lower jaw, a pair of sensor units set on the sides of the nose tip which are kept 40mm apart from the magnet, and a sensor set on the forehead to avoid geomagnetism. Calibration for the output from the sensor unit was made, and the resulting output curve was approximated to a straight line. We also tested several factors that could cause measurement error such as temperature sensitivity of the sensor, temperature sebsitivity and drift of the circuit, improvement of linearity of the sensor output, and the influence of head unrest and geomagnetism. When these factors were cleared, we proceeded to try it clinically. As a result, it was possible to measure mandibular position within a range of 30mm-50mm with an error margin of 3-5%. For centric occlusion and rest position, it became clear that we could measure mandibular position precisely by fixing the magnet onto the gingiva of the lower anterior incisor teeth.","subitem_description_type":"Abstract"},{"subitem_description":"\u54ac\u5408\u304c\u5d29\u58ca\u3057\u305f\u60a3\u8005\u3092\u6cbb\u7642\u3059\u308b\u306b\u306f\u3001\u54ac\u982d\u5d4c\u5408\u4f4d\u3092\u8a2d\u5b9a\u3059\u308b\u306b\u3042\u305f\u3063\u3066\u3001\u54ac\u5408\u9ad8\u5f84\u3092\u8a18\u9332\u3001\u8a3a\u65ad\u3059\u308b\u3053\u3068\u304c\u4e0d\u53ef\u6b20\u3067\u3042\u308b\uff61\u3053\u306e\u6e2c\u5b9a\u306b\u306f\u3001\u5f93\u6765\u30ce\u30ae\u30b9\u3092\u7528\u3044\u305f\u65b9\u6cd5\u306b\u3088\u3063\u3066\u3044\u308b\u304c\u3001\u7d4c\u6642\u7684\u306b\u6b63\u78ba\u306a\u6e2c\u5b9a\u3092\u884c\u3046\u3053\u3068\u306f\u56f0\u96e3\u3067\u3042\u3063\u305f\uff61\u672c\u7814\u7a76\u3067\u306f\u3001\u78c1\u6c17\u30bb\u30f3\u30b5\u30fc\u3092\u5fdc\u7528\u3059\u308b\u3053\u3068\u306b\u3088\u308a\u3001\u4e0b\u984e\u4f4d\u3092\u4e8c\u6b21\u5143\u3067\u7d4c\u6642\u7684\u306b\u6e2c\u5b9a\u3059\u308b\u3053\u3068\u304c\u53ef\u80fd\u306a\u3001\u5c0f\u578b\u8efd\u91cf\u306a\u96fb\u6c17\u7684\u6e2c\u5b9a\u88c5\u7f6e\u3092\u958b\u767a\u3057\u3001\u88c5\u7f6e\u306e\u7279\u6027\u3001\u304a\u3088\u3073\u81e8\u5e8a\u7684\u64cd\u4f5c\u306b\u969b\u3057\u3066\u751f\u3058\u308b\u8aa4\u5dee\u8981\u56e0\u3092\u691c\u8a0e\u3057\u305f\u3002\u88c5\u7f6e\u306f\u3001\u4e0b\u984e\u306b\u78c1\u77f3\u3092\u8a2d\u7f6e\u3057\u3001\u3053\u308c\u3088\u308a40mm\u96e2\u3057\u3066\u9f3b\u90e8\u306b2\u500b\u306e\u30bb\u30f3\u30b5\u30fc\u30e6\u30cb\u30c3\u30c8\u3092\u3001\u524d\u982d\u90e8\u306b\u88dc\u6b63\u7528\u306e\u30bb\u30f3\u30b5\u30fc\u3092\u8a2d\u7f6e\u3057\u305f\u3002\u30bb\u30f3\u30b5\u30fc\u30e6\u30cb\u30c3\u30c8\u304b\u3089\u306e\u51fa\u529b\u3092\u30ad\u30e3\u30ea\u30d6\u30ec\u30fc\u30b7\u30e7\u30f3\u3057\u3001\u5f97\u3089\u308c\u305f\u51fa\u529b\u66f2\u7dda\u3092\u76f4\u7dda\u8fd1\u4f3c\u5f0f\u3067\u88dc\u6b63\u3057\u305f\uff61\u307e\u305f\u3001\u2460
