[0061] Here, the tangent plane refers to the tangent plane of the first curved surface 112 to the main cooperation region of the opposite second guide plate 20, and the jaw plane P is substantially a horizontal plane.

[0062] In addition, the jaw is guided along the first slope 111 or the first curved surface 112, and at least a horizontal correction force can be generated, and due to the acute angle, a composite correction force in the horizontal and vertical directions actually exists.

[0063] It should be noted that the acute angle α (or β) is directed towards the lingual side or the buccal side, or the direction of the acute angle deviates from the lingual side or the buccal side.

[0064] That is, in combination with Figure 6 The first slope 111 or the first curved surface 112 can be rotated clockwise or counterclockwise around the longitudinal axis perpendicular to the jaw plane P, so that the direction of the acute angle α (or β) can be adjusted, and then a horizontal correction force with different directions can be provided, for example, the adjustment of different angle malocclusions can be realized.
