Apparatus for measuring bruxism and system for diagnosing bruxism

The invention relates to an apparatus for measuring bruxism and a system for diagnosing bruxism. The bruxism measuring apparatus comprises: an earplug-type body, which is inserted into an ear and hasa first contact line and a second contact line spaced apart from each other at a distance at a front end; and a sensor unit, which is coupled to the front end of the earplug-type body to detect the surface movement of an ear canal due to molar or mandibular occlusion. The sensor unit includes: an earphone detachably fitted into the front end, a deflection sensor mounted on the earphone to detect the surface movement of the ear canal, a first signal line, which is arranged in the earphone so as to electrically connect the deflection sensor with the first contact line; and a second signal line,which is arranged in the earphone so as to electrically connect the deflection sensor with the second contact line. 本发明涉及磨牙症测量设备和磨牙症诊断系统。根据本发明的一个实施方式的磨牙症测量设备包括：耳插式主体，所述耳插式主体被插入到耳朵中并且在前端处具有彼此以一距离间隔开的第一接触线和第二接触线；以及传感器单元，所述传感器单元联
