Background

The mouth mirror is one of the most common instruments used in the oral cavity diagnosis and treatment process. In a patient's mouth, the field of view under direct vision is often limited, and the dentist needs to use an oral mirror to observe the conditions in the patient's mouth and perform the treatment.

The existing mouth mirror is mainly of a structure that a long mirror handle is connected with a mirror surface, and helps a doctor to obtain a visual field which cannot be seen under direct vision in the process of preparing a tooth body by the doctor. Because the space in the mouth is limited, when a tooth body is prepared at certain tooth positions, the placement of the mouth mirror is limited, and the mouth mirror cannot be placed at an ideal position, so that a doctor cannot well see the conditions in the mouth. Particularly, when the second molar tooth body in the upper jaw is prepared, the far middle surface of the tooth body becomes a blind area of a visual field, and after a dental handpiece is placed in the tooth, the mouth mirror cannot be placed in the far middle area of the tooth due to the limited space, so that a doctor can obtain a good visual field, and the doctor can only operate the tooth by experience and feeling. In addition, the doctor needs to rely on a light source outside the mouth for illumination, and the angle of the light is difficult to control. Both of these factors add to the difficulty of treatment for the physician.
