In the present embodiment, the maxillary occlusal pad 10 is made of a hard resin material.

The upper contact surface 13 of the maxillary occlusal pad 10 is provided with a coating groove 20 which is sunken downwards, the coating groove 20 is formed in a mode of reverse molding, the coating groove 20 has an appearance matched with the maxillary tooth structure of the patient, the inner wall of the coating groove 20 is made of soft silicon rubber materials, and when the maxillary occlusal pad is used, the maxillary teeth are stuffed in the coating groove 20, so that the whole maxillary occlusal pad 10 is coated outside the maxillary teeth of the patient.

The upper edge of the coating groove 20 corresponding to the upper jaw contra-dental occlusion, which is close to the tongue side surface 11, is fixed with a hyperbolic tongue spring 30, and the free end of the hyperbolic tongue spring 30 extends into the upper part of the coating groove 20. The hyperbolic reed 30 is formed by bending a stainless steel wire. The number of the hyperbolic tongues is 1-4, and the number of the hyperbolic tongues is determined according to the number of teeth in the opposite occlusion.

After the maxillary occlusal pad 10 is sleeved on the maxillary tooth, the free end of the hyperbolic tongue spring 30 is tightly propped against the gingival end of the lateral surface of the maxillary anti-occlusal tooth, and a gap is reserved between the lateral surface of the anti-occlusal tooth and the inner wall of the corresponding coating groove 20 to serve as a tooth moving space, so that the maxillary occlusal tooth moving pad is suitable for moving the anti-occlusal tooth to a normal occlusion position, and the inner walls of the other coating grooves 20 except the coating groove corresponding to the anti-occlusal tooth are tightly clung to the tooth surface. The gap is arranged, so that the moving range of the orthodontic treatment of the anterior teeth with the reverse occlusions is easier to control, and excessive orthodontic treatment is avoided. The occlusal pad of the full dentition surrounding structure protects the teeth of the full dentition of a patient while correcting the affected teeth, and avoids the damage to normal teeth in the correcting process of the traditional corrector.

Meanwhile, due to the arrangement of the hyperbolic tongue spring, the lower teeth are prevented from being occluded on the labial side of the anterior teeth of the opposite occlusal teeth when the upper and lower teeth are occluded, and the palate side inward tilting force is effectively prevented from being applied to the upper teeth of the opposite occlusal teeth in the motion process of the lower teeth. Meanwhile, the anterior teeth with the reverse occlusions are released, so that the anterior teeth have a lip side moving space. The hyperbolic tongue 30 superposes the occlusion force, so that the upper anterior teeth cut toward the palate side are corrected toward the labial side to achieve the purpose of correcting the inverse occlusal occlusion of the anterior teeth, and the occlusion relation of the anterior teeth is corrected. The device has simple structure, no design of retention snap ring, good correction effect, short correction period and comfortable wearing for the sick children.
