An oral cavity insertion tool (1) has a flat base part (10), which includes a pressing piece (30) that is tabular and folded back forward at the upper end, a pressing piece (40) that is tabular and folded back forward at the lower end and, and an air hole (13) that penetrates in forward and backward directions, a backward projection part, which includes an opposing wall part (21) that projects backward from the center of the base part (10), provides a gap in which upper teeth can be inserted between the opposing wall part (21) and the base part (10), and faces the base part (10), and an opposing wall part (81) that provides a gap in which lower teeth can be inserted between the opposing wall part (81) and the base part (10), and faces the base part (10), and a lingual frenotomy pressing plate (50), which is tabular and provided to extend downward and backward from the rear end of the backward projection part, and the lingual frenotomy pressing plate (50) has a pressing part (51) that curves to curl up, towards the back, at the rear end. |

1. An oral cavity insertion tool that is wholly elastically deformable and that is inserted in an oral cavity, the oral cavity insertion tool comprising:
a flat base part comprising:
a first pressing piece that is tabular and folded back forward at an upper end;a second pressing piece that is tabular and folded back forward at a lower end and; andan air hole that penetrates in forward and backward directions; a backward projection part that projects backward from a center of the base part, and comprises:
a first opposing wall part that provides a gap in which upper teeth can be inserted between the first opposing wall part and the base part, and faces the base part; anda second opposing wall part that provides a gap in which lower teeth can be inserted between the second opposing wall part and the base part, and faces the base part; and a lingual frenotomy pressing plate that is tabular and provided to extend downward and backward from a rear end of the backward projection part, wherein the lingual frenotomy pressing plate comprises a pressing part that curves to curl up, towards the back, at a rear end. |
