[0050] As Figures 1 to 4 shown, an embodiment of the present application provides a segmentally adjustable oral appliance, including: a sub-upper alveolar monomer 1, a sub-lower alveolar monomer, a middle support body 3, and a displacement adjustment component 4. Among them, a plurality of sub-upper alveolar monomers 1 are sequentially spliced to form an upper alveolar body, and each sub-upper alveolar monomer 1 has a different number of alveoli. A plurality of sub-lower alveolar monomers are sequentially spliced to form a lower alveolar body, and each sub-lower alveolar monomer has a different number of alveoli. The middle support body 3 is disposed between the upper alveolar body and the lower alveolar body. The displacement adjustment component 4 is disposed between the upper end of each sub-upper alveolar monomer 1 and the middle support body 3, and between the lower end of each sub-lower alveolar monomer and the middle support body 3. The detachable connection of each sub-upper alveolar monomer 1 and each sub-lower alveolar monomer relative to the middle support body 3 is realized through the displacement adjustment component 4, and the relative position of each sub-upper alveolar monomer 1 and each sub-lower alveolar monomer relative to the middle support body 3 is changed by adjusting the displacement adjustment component 4.

[0051] Specifically, in an example, the middle support body 3 is set as a single plate-shaped column, and the displacement adjustment component 4 is disposed between the upper end of each sub-upper alveolar monomer 1 and the middle support body 3, and between the lower end of each sub-lower alveolar monomer and the middle support body 3. The detachable connection of each sub-upper alveolar monomer 1 and each sub-lower alveolar monomer relative to the middle support body 3 is realized through the displacement adjustment component 4, and the relative position of each sub-upper alveolar monomer 1 and each sub-lower alveolar monomer relative to the middle support body 3 is changed by adjusting the displacement adjustment component 4.

[0052] Correspondingly, the displacement adjustment assembly 4 includes: a plurality of first positioning rivet grooves 41 and rivets 42. Among them, the plurality of first positioning rivet grooves 41 are respectively arranged on the upper end surface and the lower end surface of the middle support body 3, and the plurality of first positioning rivet grooves 41 on each end surface are arranged side by side along the width direction of the middle support body 3. Among them, the width direction of the middle support body 3 is the width direction between the retaining plates of the upper alveolar body or the lower alveolar body respectively. The rivets 42 are arranged on the root sides of each sub-upper alveolar monomer 1 and on the root sides of each sub-lower alveolar monomer. The rivets 42 can be riveted in the first positioning rivet grooves 41 to achieve the detachable connection of each sub-upper alveolar monomer 1 relative to the upper end surface of the middle support body 3 and each sub-lower alveolar monomer relative to the lower end surface of the middle support body 3; and by riveting the rivets 42 in any one of the first positioning rivet grooves 41 arranged side by side along the width direction, to change the relative positions of each sub-upper alveolar monomer 1 relative to the upper end surface of the middle support body 3 and each sub-lower alveolar monomer relative to the lower end surface of the middle support body 3.

[0053] In one example, the displacement adjustment assembly 4 further includes a plurality of second positioning rivet grooves 43, and the plurality of second positioning rivet grooves 43 are respectively arranged on the upper end surface and the lower end surface of the middle support body 3, and the plurality of second positioning rivet grooves 43 on each end surface are arranged side by side along the direction perpendicular to the width direction of the middle support body 3. It should be noted that the plurality of second positioning rivet grooves 43 are located at the two rear end positions of the middle support body 3. Among them, the middle support body 3 is arranged in a U-shaped structure, and the upper alveolar body or the lower alveolar body is also arranged in a U-shaped structure respectively. The U-shaped structure of the middle support body 3 is adapted to the upper alveolar body or the lower alveolar body, and then the two rear end parts of the middle support body 3 are opposite to the two rear end parts of the upper alveolar body or the lower alveolar body. Correspondingly, the displacement adjustment of the displacement adjustment assembly 4 in the direction perpendicular to the width direction of the middle support body 3 is also limited to the sub-upper alveolar monomer 1 or the sub-lower alveolar monomer where the two rear end parts of the middle support body 3 are opposite.

[0054] In another example, the middle support body 3 includes an upper connecting body 31 and a lower connecting body 32. Among them, the upper end surface of the upper connecting body 31 faces the root side of the upper alveolar body, and the displacement adjustment assembly 4 is arranged between the upper end surface of the upper connecting body 31 and each sub-upper alveolar monomer 1. The lower end surface of the lower connecting body 32 faces the root side of the lower alveolar body, and the displacement adjustment assembly 4 is arranged between the lower end surface of the lower connecting body 32 and each sub-lower alveolar monomer.

[0055] In this embodiment, the displacement adjustment assembly 4 includes a plurality of first positioning rivet grooves 41 and rivets 42. Among them, the plurality of first positioning rivet grooves 41 are respectively arranged on the upper end surface of the upper connecting body 31 and the lower end surface of the lower connecting body 32, and the plurality of first positioning rivet grooves 41 on each end surface are arranged side by side along the width direction of the upper connecting body 31 and the lower connecting body 32. Wherein, the width direction of the middle support body 3 is the width direction between the retaining groove plates of the upper alveolar body or the lower alveolar body respectively. The rivets 42 are arranged on the root sides of each sub-upper alveolar monomer 1 and on the root sides of each sub-lower alveolar monomer.

[0056] The rivets 42 can be riveted in the first positioning rivet grooves 41 to achieve the detachable connection of each sub-upper alveolar monomer 1 relative to the upper connecting body 31 and the detachable connection of each sub-lower alveolar monomer relative to the lower connecting body 32. And by riveting the rivets 42 in any one of the first positioning rivet grooves 41 arranged side by side along the width direction, the relative position of each sub-upper alveolar monomer 1 relative to the upper connecting body 31 and the relative position of each sub-lower alveolar monomer relative to the lower connecting body 32 are changed.

[0057] In an example, the displacement adjustment assembly 4 further includes a plurality of second positioning rivet grooves 43. The plurality of second positioning rivet grooves 43 are respectively arranged on the upper end surface and the lower end surface of the middle support body 3, and the plurality of second positioning rivet grooves 43 on each end surface are arranged side by side along the width direction perpendicular to the middle support body 3. It should be noted that the plurality of second positioning rivet grooves 43 are located at the two rear end positions of the middle support body 3. Wherein, the middle support body 3 is arranged in a U-shaped structure, and the upper alveolar body or the lower alveolar body is also respectively arranged in a U-shaped structure. The U-shaped structure of the middle support body 3 is adapted to the upper alveolar body or the lower alveolar body, and then the two rear ends of the middle support body 3 are opposite to the two rear ends of the upper alveolar body or the lower alveolar body. Correspondingly, the displacement adjustment of the displacement adjustment assembly 4 in the width direction perpendicular to the middle support body 3 is also limited to the sub-upper alveolar monomer 1 or the sub-lower alveolar monomer where the two rear ends of the middle support body 3 are opposite.

[0058] In an example, if the positions of the sub-upper alveolar monomer 1 and the sub-lower alveolar monomer are not adjusted, only one rivet 42 is provided on each sub-upper alveolar monomer 1 and each sub-lower alveolar monomer, and each rivet 42 can correspondingly be provided with only one first positioning rivet groove 41. By riveting the rivet 42 in the first positioning rivet groove 41, the positioning installation of the sub-upper alveolar monomer 1 or the sub-lower alveolar monomer can be achieved.

[0059] In an example, the displacement adjustment assembly 4 further includes a plurality of second positioning rivet grooves 43. The plurality of second positioning rivet grooves 43 are respectively arranged on the upper end surface of the upper connecting body 31 and the lower end surface of the lower connecting body 32, and the plurality of second positioning rivet grooves 43 on each end surface are arranged side by side along the width direction perpendicular to the upper connecting body 31 and the lower connecting body 32. It should be noted that the plurality of second positioning rivet grooves 43 are located at the two rear end positions of the middle support body 3.

[0060] In one example, the displacement adjustment component 4 can also be a snap - connectable structure including a groove and a clamping body. That is, a plurality of grooves are provided, and the plurality of grooves are respectively provided on the upper end surface and the lower end surface of the middle support body 3, and the plurality of grooves on each end surface are arranged side by side along the width direction of the middle support body 3. Among them, the width direction of the middle support body 3 is the width direction between the retaining groove plates of the upper alveolar body or the lower alveolar body respectively. The clamping body is provided on the root side of each sub - upper alveolar monomer 1 and on the root side of each sub - lower alveolar monomer. The clamping body can be snap - fitted into the groove to realize the detachable connection of each sub - upper alveolar monomer 1 relative to the upper connecting body 31 and the detachable connection of each sub - lower alveolar monomer relative to the lower connecting body 32. And by snap - fitting the clamping body into any one of the grooves arranged side by side along the width direction, the relative position of each sub - upper alveolar monomer 1 relative to the upper connecting body 31 and the relative position of each sub - lower alveolar monomer relative to the lower connecting body 32 can be changed.

[0061] In this embodiment, in order to improve the connection stability between the upper connecting body 31 and the lower connecting body 32, a plurality of support connection structures 5 that can be connected are provided between the lower end surface of the upper connecting body 31 and the upper end surface of the lower connecting body 32. The connection between the upper connecting body 31 and the lower connecting body 32 and the relative height adjustment of the upper connecting body 31 and the lower connecting body 32 in the vertical direction are realized through the plurality of support connection structures 5.

[0062] Specifically, in one example, the support connection structure 5 includes a plurality of card slots and an adjustable telescopic rod.

The adjustable telescopic rod can be telescopically adjusted to form different lengths, and convex body structures are respectively provided at the opposite ends of the adjustable telescopic rod. The convex body structures can be snap - connected to any one of the card slots. By adjusting the adjustable telescopic rod to form different lengths, the convex body structures at the opposite ends of the adjustable telescopic rod are correspondingly snap - connected to the card slots at different height positions in the vertical direction, so as to adjust the relative height of the upper connecting body 31 and the lower connecting body 32 in the vertical direction.

[0063] In one example, the support connection structure 5 includes a threaded groove and a stud. Among them, the threaded grooves are respectively arranged on the upper connecting body 31 and the lower connecting body 32 along the vertical direction, and the openings of the threaded grooves are respectively arranged on the lower end surface of the upper connecting body 31 and the upper end surface of the lower connecting body 32. The stud is arranged between the upper connecting body 31 and the lower connecting body 32, and the opposite ends of the stud are respectively screwed into the threaded grooves. By adjusting the rotation direction of the end of the stud relative to the threaded groove, the relative height of the upper connecting body 31 and the lower connecting body 32 in the vertical direction is adjusted.

[0064] In this embodiment, in order to prevent substances in the oral cavity from entering the middle support body 3 composed of the upper connecting body 31 and the lower connecting body 32, it further includes: a first encapsulation body, a first snap-in groove, and a first snap-in protrusion.

[0065] An embodiment of the present application provides an orthodontic appliance that can be adjusted segmentally, including: a sub-upper alveolar monomer 1, a sub-lower alveolar monomer, a middle support body 3, and a displacement adjustment component 4. Among them, a plurality of sub-upper alveolar monomers 1 are spliced in sequence to form an upper alveolar body, and each sub-upper alveolar monomer 1 has a different number of alveoli. A plurality of sub-lower alveolar monomers are spliced in sequence to form a lower alveolar body, and each sub-lower alveolar monomer has a different number of alveoli. The middle support body 3 is arranged between the upper alveolar body and the lower alveolar body. The displacement adjustment component 4 is arranged between the upper end of each sub-upper alveolar monomer 1 and the middle support body 3, and between the lower end of each sub-lower alveolar monomer and the middle support body 3. Through the displacement adjustment component 4, the detachable connection of each sub-upper alveolar monomer 1 and each sub-lower alveolar monomer relative to the middle support body 3 is realized, and by adjusting the displacement adjustment component 4, the relative positions of each sub-upper alveolar monomer 1 and each sub-lower alveolar monomer relative to the middle support body 3 are changed.

[0066] In the embodiment of the present application, through the displacement adjustment component 4, the detachable connection of each sub-upper alveolar monomer 1 and each sub-lower alveolar monomer relative to the middle support body 3 is realized, and the segmented replacement of each sub-upper alveolar monomer 1 and each sub-lower alveolar monomer can be realized. Therefore, when only one dental crown groove of the upper dental crown groove or the lower dental crown groove needs to be replaced, it is no longer necessary to replace the upper alveolar body or the lower alveolar body, thereby reducing the cost of using the orthodontic appliance. Based on the relatively low cost of the orthodontic appliance components, the corresponding components can be replaced in a timely manner, and then the orthodontic requirements can be met and the orthodontic effect can be improved.

[0067] In addition, by adjusting the displacement adjustment component 4 to change the relative positions of each sub-upper alveolar monomer 1 and each sub-lower alveolar monomer relative to the middle support body 3, the displacement angles of the sub-upper alveolar monomer 1 relative to some upper teeth and the sub-lower alveolar monomer relative to some lower teeth are adjusted, thereby meeting the orthodontic requirements and improving the orthodontic effect.
