[0022] Combination Figure 1-4The mandibular anterior guide shell-shaped dental device for tooth correction of this embodiment includes a shell-shaped dental device for accommodating teeth, and the shell-shaped dental device includes a first orthodontic appliance 1 and a second orthodontic appliance 2. The first orthodontic appliance 1 is provided with a first protrusion 3 on the occlusal surface corresponding to the posterior tooth area in the direction of the jaw, and the second orthodontic appliance 2 is provided with a second protrusion 4 on the occlusal surface corresponding to the posterior tooth area in the direction of the jaw. The first protrusion 3 and the second protrusion 4 are arranged correspondingly up and down, and the first protrusion 3 and the second protrusion 4 are provided with corresponding guide surfaces for auxiliary guidance during occlusion, so that the mandibular incisor end and the maxillary incisor end tend to be aligned, and the guide surface is a ramp slide. The first protrusion 3 is provided with a first guide surface 61, and the second protrusion 4 is provided with a second guide surface 62, and the first guide surface 61 and the second guide surface 62 cooperate with each other.

[0023] Specifically, in this embodiment, a friction portion is provided on the guide surface of the first protrusion 3 and the second protrusion 4. When the occlusal incisor ends are aligned and reconstructed, the friction portion allows the upper and lower jaws to contact smoothly, further improving the correction effect.

[0024] Preferably, in this embodiment, the first protruding portion 3 on the first orthodontic appliance 1 is provided with a plurality of first concave structures 51 , and the first concave structures 51 are symmetrically arranged on both sides of the first protruding portion 3 .

[0025] Preferably, in this embodiment, the first concave structure 51 is elliptical.

[0026] Specifically, in the present embodiment, two first concave structures 51 are provided on each side of the first protruding portion 3 . The first concave structures 51 are arranged inwardly along the height direction. The concave curved surface can act as a reinforcing rib, thereby effectively enhancing the strength of the first protruding portion 3 .

[0027] In this embodiment, the guide surface of the first protrusion 3 is a convex block, and the guide surface of the second protrusion 4 is a concave groove matching the convex block. The concave-convex guide surface is conducive to occlusal stability and can effectively limit the coronal sliding of the mandible.

[0028] In this embodiment, preferably, a gap is left between the matching guide surfaces of the first protrusion 3 and the second protrusion 4, and the gap is controlled to be 1±0.2 mm. This gap is used to increase the thickness of the appliance after coating, thereby increasing the effect of incisor end alignment.

[0029] Preferably, in this embodiment, the width of the second protrusion 4 at one end away from the guide surface is smaller than the width of the other end of the guide surface, and a circular arc-shaped concave structure is used as a transition between the two ends. The setting of the circular arc-shaped concave structure can enhance the strength of the second protrusion 4.

[0030] Specifically, in this embodiment, the width of the second protrusion 4 away from one end of the guide surface is in a decreasing trend, and the closer to the guide surface, the larger the width. Such a configuration can further enhance the strength of the second protrusion 4.

[0031] In this embodiment, preferably, the end of the first protrusion 3 away from the guide surface is provided with the second concave structure 52. The second concave structure 52 is provided so that the end surface forms a reinforcing rib structure, further improving the strength of the first protrusion 3.

[0032] Preferably, in this embodiment, the first orthodontic appliance 1 and the second orthodontic appliance 2 are both integrally formed structures.

[0033] Preferably, in this embodiment, the first protrusion 3 and the second protrusion 4 are both hollow structures in the middle.

[0034] In this embodiment, preferably, the guide surface of the shell-shaped dental instrument except the first protrusion 3 is not chamfered, and the rest of the parts are chamfered.

[0035] Specifically, in the present embodiment, except for the guide surface, all other parts of the first raised portion 3 are designed with chamfered corners, such as the first concave structure 51, the second concave structure 52 and the end face corners, and the arc-shaped concave structure and the end face corners of the second raised portion 4 are designed with chamfered corners. The chamfered corner design is used to improve the demolding process.

[0036] The mandibular leading shell-shaped dental instrument for tooth correction in this embodiment effectively enhances the strength of the first protrusion 3 by arranging the first concave structure 51 and the second concave structure 52 on the first protrusion 3. The second protrusion 4 effectively enhances the strength of the second protrusion 4 by the transition design of decreasing away from the guide surface and the arc-shaped concave structure. The ramp matching design of the concave and convex guide surfaces between the first protrusion 3 and the second protrusion 4 improves the stability of the occlusion, and the mandibular position is improved by gradually guiding the movement of the mandible, thereby achieving the treatment purpose.
