  However, the opener described in Patent Document 1 is held by both back teeth and is strongly mounted in the oral cavity. In the mounted state, the portion held by the back teeth is particularly inside the back teeth. It is difficult to see from the outside, and it is difficult to perform treatment such as treatment in the oral cavity or cleaning by brushing teeth. In addition, if the mouth opener is moved to change the position in the mouth to change the teeth to be treated, the part held in the back teeth will move in the mouth. It may cause discomfort to the therapist and cause resistance.

  In addition, the opening device described in Patent Document 2 is hung on the corners of both sides of the lip, and a photographing assistant pulls the back of the person requiring treatment, and takes a photograph with the teeth arranged with the upper and lower jaws closed. However, if the person requiring treatment is resistant, the upper and lower jaws cannot be opened, so that the oral cavity cannot be reliably cleaned or treated.

  The present invention has been proposed in order to solve the above-mentioned problems, and the opening device is attached to the oral cavity of the person requiring treatment to be opened widely, so that not only the lip side of the tooth but also the lingual side of the mouth An object of the present invention is to provide an opening device that can be used without resistance even for infants and young children because it can be treated and cleaned without any discomfort to the person requiring treatment.

  Therefore, the caregiver can clean the exposed lip side surface, lingual side surface and occlusal surface of the right tooth with a toothbrush or treat the tooth with a treatment tool. During this time, if the person requiring treatment strongly bites the first tongue piece, the lip support part does not move finely, so the caregiver does not need to keep holding the grip part. However, if the person requiring treatment cannot continue to bite the first tongue piece, the caregiver only needs to keep holding the grip portion and maintain the lip support portion.

Then, after cleaning and treating the lip side surface, tongue side surface and occlusal surface of the right tooth, the caregiver removes the lip support part from the oral cavity of the person requiring treatment while grasping the grasping part, and requires treatment by turning the opener upside down. Put the second tongue piece inside the left cheek, and slightly pull it sideways to press the second tongue piece in contact with the buccal surface from the inside of the left cheek. A large space is formed between the molar teeth and the inner surface of the left cheek, the lip support part is slightly rotated in the oral cavity by the grip part, and the first tongue piece is bitten near the right side incisor or canine. I will. Therefore, as with the right side, the left oral cavity of the person requiring treatment is greatly opened, and the left lip side surface, the lingual side surface, and the occlusal surface of the molar tooth are exposed. Can do.
As described above, according to the present invention, a patient who needs treatment is surely brushed with a toothbrush not only on the lip side surface and lingual side surface of almost all teeth in the oral cavity but also on the occlusal surface without causing discomfort or discomfort. Or can be treated with a treatment tool.
