Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0022] First embodiment:

[0023] See also Figure 1As shown, the utility model provides an invisible brace, including a brace bracket 1, the brace bracket 1 includes an outer wrapping surface 101, a tooth surface layer 102 and an inner wrapping surface 103, the outer wrapping surface 101, the tooth surface layer 102 and the inner wrapping surface 103 form a "U"-shaped opening covering the crown position, the outer wrapping surface 101, the tooth surface layer 102 and the inner wrapping surface 103 are processed as one piece, and the tooth surface layer 102 is provided with a tooth-shaped protrusion 102a corresponding to the inner tooth working surface, so as to prevent food debris from reaching the tooth surface groove from the edge position of the brace bracket 1, and the tooth-shaped protrusion 102a can be used to limit and protect the inner tooth position;

[0024] A metal strip 3 corresponding to the external teeth is provided inside the outer wrapping surface 101. The metal strip 3 extends laterally along the outer wrapping surface 101. A plurality of tensioning bands 301 are connected to the metal strip 3. There are two tensioning bands 301, which are respectively close to the two ends of the metal strip 3. The tensioning bands 301 extend from the outer wrapping surface 101 and the tooth surface layer 102 to the surface of the inner wrapping surface 103 in sequence, and are used to pull the external teeth. The metal strip 3 and the tensioning band 301 are used to form a support for the orthodontic bracket 1, and the external teeth are pulled laterally and longitudinally to improve the correction effect on the teeth.

[0025] The second embodiment is different from the first embodiment in that:

[0026] The inner side of the inner wrapping surface 103 is provided with an inner cushion layer 2 corresponding to the position of the inner gums of the outer teeth. The side of the inner cushion layer 2 away from the inner wrapping surface 103 is in an arc structure, which can be tightened more after the device is worn.
