PROBLEM TO BE SOLVED: To provide a technology capable of determining a biological state on the basis of information, other than a sugar concentration in saliva, detectable in the oral cavity.SOLUTION: A right artificial tooth 10R and a left artificial tooth 10L each have a pressure sensor 26 for detecting pressure applied on the occlusion surface thereof, and a communication device for transmitting information detected by the pressure sensor 26 to a determination unit 23, the determination unit 23 acquiring, via the communication device, the information detected by the pressure sensors 26 of each of the right artificial tooth 10R and the left artificial tooth 10L, and determining a biological state at least on the basis of the magnitude of the pressures applied on each of the occlusion surfaces of the right artificial tooth 10R and the left artificial tooth 10L, and the balance between the pressures applied on the occlusion surfaces of the right artificial tooth 10R and the left artificial tooth 10L.COPYRIGHT: (C)2016,JPO&INPIT【課題】唾液中の糖濃度以外の口腔内で検出可能な情報に基づき生体の状態を判定することが可能な技術を実現する。【解決手段】右側人工歯10R及び左側人工歯10Lのそれぞれが、噛み合わせ面に作用する圧力を検出する圧力センサ26と、圧力センサ26の検出情報を判定部23に送信する通信装置とを有する。判定部23が、通信装置を介して右側人工歯10R及び左側人工歯10Lのそれぞれの圧力センサ26の検出情報を取得し、右側人工歯10R及び左側人工歯10Lのそれぞれの噛み合わせ面に作用する圧力の大きさと、噛み合わせ面に作用する圧力の右側人工歯10Rと左側人工歯10Lとのバランスとに少なくとも基づいて、生体の状態を判定する。【選択図】図1
