The present invention is a device for space closure and space securing during orthodontic treatment, which enables the movement of teeth, the intrusion and extrusion of teeth, and can be aesthetic and comfortable. . When the interdental space was closed or the space was secured by using a circular spring, an elastic force such as silicone or rubber, the tooth movement could not be performed. The space between the teeth was non-aesthetic when the interdental space was closed. Anterior teeth were defined when the interdental space was closed during orthodontic treatment with extraction. The present invention uses a plate-shaped spring, the tooth movement of the tooth is possible. When using a circular spring and rubber, silicone elastomer, there is a problem of dropping by the mastication pressure, and when the method of the orthodontic method is usually used, the patient suffers from swelling, causing discomfort and pain, and a lot of trouble during the procedure. The effect of the present invention is the tooth movement of the tooth, the intrusion (intrusion) and extrusion (extrusion) of the tooth is possible, and can also be inclined movement as necessary. In addition, the artificial tooth is attached to the plate-shaped spring narrow side (cheek side) (cheek side) during the extraction correction process to make the extraction space aesthetically invisible. By using the bending elasticity of the leaf spring and using the hinge, tooth movement, tooth intrusion and extrusion are possible. In the space closing and space securing device using a plate-shaped spring, a hole is drilled in the adjacent part of the tooth so that the teeth are completely collected and attached to each other. Abutment is made on the cheek side (cheek side) or labia side (lip side) to improve the aesthetics. A polygonal shape is formed on the narrow side (cheek side) (cheek side) or the labial side (lip side) on the linear spring to attach artificial teeth to improve aesthetics. When using a
