摘要：
A mouth opening instrument includes an upper member suitable for attaching on an upper jaw side within the mouth of a patient and a lower member suitable for attaching on a lower jaw side. The instrument further includes a connecting section, a control section, and an input section. The connecting section connects end portions of the upper member and the lower member such that a resistance of opening or closing actions of the upper member and the lower member are controllable. The control section controls the resistance of opening or closing actions of the upper member and the lower member. The input section receives an operating state signal indicating an operating state of a dental treatment device. When the operating state signal indicating an operating state of a dental treatment device is inputted, the closing resistance of the upper member and the lower member is set to be greater than that at a time when the operating state signal is not inputted.
